Abstract

We present a model of TCP flows suited to Internet backbone traffic, where links are usually not congested. We characterize the traffic using information on flows, i.e., arrival time, size, and duration. The major contribution of this paper is a model capturing the variation of the transmission rate during a TCP flow solely based on the above flow parameters. This model accounts for the dynamics of TCP congestion window and for the Timeout mechanism. It is independent of the packet loss rate and the round-trip time of the connection. We then model the traffic on a backbone link by aggregating TCP flows. Our model is easy to compute, and we show via simulations that it gives a good approximation of Internet backbone traffic.

Internet backbone

The Internet backbone may be defined by the principal data routes between large, strategically interconnected computer networks and core routers of the Internet. These data routes are hosted by commercial, government, academic and other high-capacity network centers, as well as the Internet exchange points and network access points, that exchange Internet traffic between the countries, continents, and across the oceans.

Backbone network

A backbone or core network is a part of a computer network which interconnects networks, providing a path for the exchange of information between different LANs or subnetworks. A backbone can tie together diverse networks in the same building, in different buildings in a campus environment, or over wide areas. Normally, the backbone's capacity is greater than the networks connected to it.

Internet traffic

Internet traffic is the flow of data within the entire Internet, or in certain network links of its constituent networks. Common traffic measurements are total volume, in units of multiples of the byte, or as transmission rates in bytes per certain time units. As the topology of the Internet is not hierarchical, no single point of measurement is possible for total Internet traffic. Traffic data may be obtained from the Tier 1 network providers' peering points for indications of volume and growth.
