Internet traffic monitoring and accounting. Local network traffic monitoring

These are programs that allow you to monitor active connections on all network interfaces.

Modern tools for detailed and detailed traffic monitoring, as a rule:

are quite affordable;
allow you to limit the speed of each connection separately;
give a clear picture of which files and programs load the network and what speed they need to have;
allow you to determine the sources of the greatest traffic consumption.

The program will help you decide on your priorities when using the network.

Today there are many similar utilities for monitoring and planning traffic consumption.

CommTraffic

This is a program for monitoring Internet traffic both on a local network (monitors the Internet activity of several clients at once) and on a personal computer using a modem connection. Accounting and statistics of Internet work will be displayed in the form of bandwidth graphs. They show the amount of outgoing, incoming and total traffic.

The program can be configured for almost any tariff plan, which is based on the established volume, takes into account the time of day and connection time. The CommTraffic utility is equipped with:

convenient indication;
accurate cost calculation;
possibility of notification in case of overspending.

Moreover, it is simple and easy to use. Once you set a traffic and time limit that matches your tariff plan, you will receive notifications with a sound signal or a message to the specified address when you approach the set limits.

Program for monitoring Internet traffic Network Meter

An application for collecting network information that allows you to monitor all network adapters installed in the system. Also provides detailed statistics about outgoing and incoming traffic. First, configure the downloaded program when you first launch it. To do this, specify what data you want to see in the main window, and the adapters that Network Meter will “monitor”.

Minimize the utility window to the notification panel so that it does not take up space on your desktop. Even in this state, the application continues to work in the background.

The program will plot graphs of network connection consumption intensity in real time. It is not overloaded with unnecessary interface elements and settings. The graphical shell of the utility is clear and simple. You can also use it to see:

Internet session duration, MAC address and IP;

Internet speed and Internet traffic accounting program

A free utility for those involved in system administration or home network monitoring.

Traffic counter useful thing. Especially if you have limited access to the network in terms of time or the amount of megabytes used. Not everyone has unlimited, right? Many people have unlimited access at home, but use a 3G connection or mobile Internet outside the home for a laptop, like me, for example. And this type of communication is usually limited. You need to monitor your traffic consumption so as not to lose money if you overspend.

I suggest you use NetWorx — a free program for recording Internet traffic and monitoring Internet connection speed. This small, necessary program will help you monitor the speed (traffic cops don’t sleep!) of movement on the network, and will also show how many kilograms of the Internet have been downloaded in a certain time.

By using NetWorx You can set a time or megabyte limit. And when this threshold is reached, a notification will appear on the screen saying that your song has been sung and it’s time to wind down. You can also set it to automatically disconnect from the network or launch certain programs. Convenient, useful, easy.

Download and install NetWorx: 1.7MB

When you right-click on the tray icon, the following menu will appear...

Any administrator sooner or later receives instructions from management: “count who goes online and how much they download.” For providers, it is complemented by the tasks of “letting whoever needs it in, taking payment, limiting access.” What to count? How? Where? There is a lot of fragmentary information, it is not structured. We will save the novice admin from tedious searches by providing him with general knowledge and useful links to hardware.
In this article I will try to describe the principles of organizing the collection, accounting and control of traffic on the network. We will look at the issue and list possible ways to retrieve information from network devices.

This is the first theoretical article in a series of articles devoted to the collection, accounting, management and billing of traffic and IT resources.

Internet access structure

In general, the network access structure looks like this:

External resources - the Internet, with all sites, servers, addresses and other things that do not belong to the network that you control.
Access device – router (hardware or PC-based), switch, VPN server or concentrator.
Internal resources are a set of computers, subnets, subscribers whose operation on the network must be taken into account or controlled.
A management or accounting server is a device on which specialized software runs. Can be functionally combined with a software router.

In this structure, network traffic passes from external resources to internal ones, and back, through the access device. It transmits traffic information to the management server. The control server processes this information, stores it in the database, displays it, and issues blocking commands. However, not all combinations of access devices (methods) and collection and control methods are compatible. The various options will be discussed below.

Network traffic

First, you need to define what is meant by “network traffic” and what useful statistical information can be extracted from the stream of user data.
The dominant internetworking protocol is still IP version 4. The IP protocol corresponds to layer 3 of the OSI model (L3). Information (data) between the sender and the recipient is packaged into packets - having a header and a “payload”. The header determines where the packet is coming from and to (sender and recipient IP addresses), packet size, and payload type. The bulk of network traffic consists of packets with UDP and TCP payloads - these are Layer 4 (L4) protocols. In addition to addresses, the header of these two protocols contains port numbers, which determine the type of service (application) transmitting data.

To transmit an IP packet over wires (or radio), network devices are forced to “wrap” (encapsulate) it in a Layer 2 (L2) protocol packet. The most common protocol of this type is Ethernet. The actual transmission “to the wire” occurs at the 1st level. Typically, the access device (router) does not analyze packet headers at levels higher than level 4 (with the exception of intelligent firewalls).
Information from the fields of addresses, ports, protocols and length counters from the L3 and L4 headers of data packets constitutes the “raw material” that is used in traffic accounting and management. The actual amount of information transmitted is found in the Length field of the IP header (including the length of the header itself). By the way, due to packet fragmentation due to the MTU mechanism, the total amount of data transmitted is always greater than the payload size.

The total length of the IP and TCP/UDP fields of the packet that are interesting to us in this context is 2...10% of the total length of the packet. If you process and store all this information batch by batch, there will not be enough resources. Fortunately, the vast majority of traffic is structured to consist of a series of “conversations” between external and internal network devices, called “flows.” For example, as part of one operation of sending an email (SMTP protocol), a TCP session is opened between the client and the server. It is characterized by a constant set of parameters (source IP address, source TCP port, destination IP address, destination TCP port). Instead of processing and storing information packet by packet, it is much more convenient to store flow parameters (addresses and ports), as well as additional information - the number and sum of lengths of packets transmitted in each direction, optionally session duration, router interface indexes, ToS field value, etc. This approach is beneficial for connection-oriented protocols (TCP), where it is possible to explicitly intercept the termination of a session. However, even for non-session-oriented protocols, it is possible to perform aggregation and logical completion of a flow record based on, for example, a timeout. Below is an excerpt from the SQL database of our own billing system, which logs information about traffic flows:

It is necessary to note the case when the access device performs address translation (NAT, masquerading) to organize Internet access for local network computers using one, external, public IP address. In this case, a special mechanism replaces IP addresses and TCP/UDP ports of traffic packets, replacing internal (not routable on the Internet) addresses according to its dynamic translation table. In this configuration, it is necessary to remember that in order to correctly record data on internal network hosts, statistics must be collected in a way and in a place where the translation result does not yet “anonymize” internal addresses.

Methods for collecting traffic/statistics information

You can capture and process information about passing traffic directly on the access device itself (PC router, VPN server), transferring it from this device to a separate server (NetFlow, SNMP), or “from the wire” (tap, SPAN). Let's look at all the options in order.

PC router

Let's consider the simplest case - an access device (router) based on a PC running Linux.

How to set up such a server, address translation and routing, a lot has been written. We are interested in the next logical step - information on how to obtain information about the traffic passing through such a server. There are three common methods:

intercepting (copying) packets passing through the server’s network card using the libpcap library
intercepting packets passing through the built-in firewall
using third-party tools for converting packet-by-packet statistics (obtained by one of the two previous methods) into a netflow aggregated information stream

Libpcap

In the first case, a copy of the packet passing through the interface, after passing the filter (man pcap-filter), can be requested by a client program on the server written using this library. The packet arrives with a layer 2 header (Ethernet). It is possible to limit the length of the information captured (if we are only interested in information from its header). Examples of such programs are tcpdump and Wireshark. There is an implementation of libpcap for Windows. If address translation is used on a PC router, such interception can only be carried out on its internal interface connected to local users. On the external interface, after translation, IP packets do not contain information about the internal hosts of the network. However, with this method it is impossible to take into account the traffic generated by the server itself on the Internet (which is important if it runs a web or email service).

libpcap requires support from the operating system, which currently amounts to installing a single library. In this case, the application (user) program that collects packages must:

open the required interface
specify the filter through which to pass received packets, the size of the captured part (snaplen), the buffer size,
set the promisc parameter, which puts the network interface into capture mode for all packets passing by, and not just those addressed to the MAC address of this interface
set a function (callback) called on each received packet.

When a packet is transmitted through the selected interface, after passing the filter, this function receives a buffer containing Ethernet, (VLAN), IP, etc. headers, total size up to snaplen. Since the libcap library copies packets, it cannot be used to block their passage. In this case, the traffic collection and processing program will have to use alternative methods, such as calling a script to place a given IP address in a traffic blocking rule.

Firewall

Capturing data passing through the firewall allows you to take into account both the traffic of the server itself and the traffic of network users, even when address translation is running. The main thing in this case is to correctly formulate the capture rule and put it in the right place. This rule activates the transfer of the packet towards the system library, from where the traffic accounting and management application can receive it. For Linux OS, iptables is used as a firewall, and interception tools are ipq, netfliter_queue or ulog. For OC FreeBSD – ipfw with rules like tee or divert. In any case, the firewall mechanism is complemented by the ability to work with a user program in the following way:

A user program - a traffic handler - registers itself in the system using a system call or a library.
A user program or external script installs a rule in the firewall, “wrapping” the selected traffic (according to the rule) inside the handler.
For each passing packet, the handler receives its contents in the form of a memory buffer (with IP headers, etc. After processing (accounting), the program must also tell the operating system kernel what to do next with such a packet - discard it or pass it on. Alternatively, it is possible pass the modified packet to the kernel.

Since the IP packet is not copied, but sent to the software for analysis, it becomes possible to “eject” it, and therefore, completely or partially restrict traffic of a certain type (for example, to a selected local network subscriber). However, if the application program stops responding to the kernel about its decision (hung, for example), traffic through the server is simply blocked.
It should be noted that the described mechanisms, with significant volumes of transmitted traffic, create excessive load on the server, which is associated with the constant copying of data from the kernel to the user program. The method of collecting statistics at the OS kernel level, with the output of aggregated statistics to the application program via the NetFlow protocol, does not have this drawback.

Netflow

This protocol was developed by Cisco Systems to export traffic information from routers for the purpose of traffic accounting and analysis. The most popular version 5 now provides the recipient with a stream of structured data in the form of UDP packets containing information about past traffic in the form of so-called flow records:

The amount of information about traffic is several orders of magnitude smaller than the traffic itself, which is especially important in large and distributed networks. Of course, it is impossible to block the transfer of information when collecting statistics via netflow (unless additional mechanisms are used).
Currently, a further development of this protocol is becoming popular - version 9, based on the template flow record structure, implementation for devices from other manufacturers (sFlow). Recently, the IPFIX standard was adopted, which allows statistics to be transmitted via protocols at deeper levels (for example, by application type).
The implementation of netflow sources (agents, probes) is available for PC routers, both in the form of utilities working according to the mechanisms described above (flowprobe, softflowd), and directly built into the OS kernel (FreeBSD: ng_netgraph, Linux:). For software routers, the netflow statistics stream can be received and processed locally on the router itself, or sent over the network (transfer protocol - over UDP) to the receiving device (collector).

The collector program can collect information from many sources at once, being able to distinguish their traffic even with overlapping address spaces. Using additional tools such as nprobe, it is also possible to perform additional data aggregation, stream bifurcation or protocol conversion, which is important when managing a large and distributed network with dozens of routers.

Netflow export functions support routers from Cisco Systems, Mikrotik, and some others. Similar functionality (with other export protocols) is supported by all major network equipment manufacturers.

Libpcap “outside”

Let's complicate the task a little. What if your access device is a hardware router from another manufacturer? For example, D-Link, ASUS, Trendnet, etc. It is most likely impossible to install additional data acquisition software on it. Alternatively, you have a smart access device, but it is not possible to configure it (you don’t have rights, or it is controlled by your provider). In this case, you can collect information about traffic directly at the point where the access device meets the internal network, using “hardware” packet copying tools. In this case, you will definitely need a separate server with a dedicated network card to receive copies of Ethernet packets.
The server must use the packet collection mechanism using the libpcap method described above, and our task is to submit a data stream identical to that coming from the access server to the input of the network card dedicated for this purpose. For this you can use:

Ethernet - hub: a device that simply forwards packets between all its ports indiscriminately. In modern realities, it can be found somewhere in a dusty warehouse, and using this method is not recommended: unreliable, low speed (there are no hubs with a speed of 1 Gbit/s)
Ethernet - a switch with the ability to mirror (mirroring, SPAN ports. Modern smart (and expensive) switches allow you to copy all traffic (incoming, outgoing, both) of another physical interface, VLAN, including remote (RSPAN) to a specified port
Hardware splitter, which may require installation of two network cards instead of one to collect - and this is in addition to the main, system one.

Naturally, you can configure a SPAN port on the access device itself (router), if it allows it - Cisco Catalyst 6500, Cisco ASA. Here is an example of such a configuration for a Cisco switch:
monitor session 1 source vlan 100 ! where do we get the packages from?
monitor session 1 destination interface Gi6/3! where do we issue packages?

SNMP

What if we don’t have a router under our control, we don’t want to contact netflow, we’re not interested in the details of our users’ traffic. They are simply connected to the network through a managed switch, and we just need to roughly estimate the amount of traffic going to each of its ports. As you know, network devices with remote control support and can display counters of packets (bytes) passing through network interfaces. To poll them, it would be correct to use the standardized remote management protocol SNMP. Using it, you can quite easily obtain not only the values of the specified counters, but also other parameters, such as the name and description of the interface, MAC addresses visible through it, and other useful information. This is done both by command line utilities (snmpwalk), graphical SNMP browsers, and more complex network monitoring programs (rrdtools, cacti, zabbix, whats up gold, etc.). However, this method has two significant drawbacks:

Traffic blocking can only be done by completely disabling the interface, using the same SNMP
traffic counters taken via SNMP refer to the sum of the lengths of Ethernet packets (unicast, broadcast and multicast separately), while the rest of the previously described tools give values relative to IP packets. This creates a noticeable discrepancy (especially on short packets) due to the overhead caused by the length of the Ethernet header (however, this can be approximately combated: L3_byte = L2_byte - L2_packets * 38).

VPN

Separately, it is worth considering the case of user access to the network by explicitly establishing a connection to the access server. A classic example is the good old dial-up, the analogue of which in the modern world is VPN remote access services (PPTP, PPPoE, L2TP, OpenVPN, IPSEC)

The access device not only routes user IP traffic, but also acts as a specialized VPN server and terminates logical tunnels (often encrypted) within which user traffic is transmitted.
To account for such traffic, you can use all the tools described above (and they are well suited for deep analysis by ports/protocols), as well as additional mechanisms that provide VPN access control tools. First of all, we will talk about the RADIUS protocol. His work is a rather complex topic. We will briefly mention that the control (authorization) of access to the VPN server (RADIUS client) is controlled by a special application (RADIUS server), which has a database (text file, SQL, Active Directory) of allowed users with their attributes (restrictions on connection speeds, assigned IP addresses). In addition to the authorization process, the client periodically transmits accounting messages to the server, information about the state of each currently running VPN session, including counters of transmitted bytes and packets.

Conclusion

Let's bring all the methods for collecting traffic information described above together:

Let's summarize. In practice, there are a large number of methods for connecting the network you manage (with clients or office subscribers) to an external network infrastructure, using a number of access tools - software and hardware routers, switches, VPN servers. However, in almost any case, it is possible to come up with a scheme where information about traffic transmitted over the network can be sent to a software or hardware tool for its analysis and management. It is also possible that this tool will allow feedback to the access device, using intelligent access restriction algorithms for individual clients, protocols, and other things.
This is where I will finish the analysis of the materiel. The remaining unanswered topics are:

how and where the collected traffic data goes
traffic accounting software
What is the difference between billing and a simple “counter”
How can you impose traffic restrictions?
accounting and restriction of visited websites
