Embodiment

[0042] A kind of embodiment of the present invention is, a kind of BT flow optimization method that strengthens Internet core network flow stability, the step that comprises is:

[0043] A. BT user p obtains the list of candidate BT users of the user group from the tracking server;

[0044] B. BT user p selects a given number of candidate BT users from the list of candidate BT users to establish a neighbor connection and obtain neighbor BT users;

[0045] C. BT user p periodically selects a given number of neighbor BT users from the neighbor BT users to unblock, forming unblocked BT users, and blocks unselected neighbor BT users, and the unblocked BT users start from BT User p downloads interested file fragments. If BT user p is unblocked by neighbor BT users, BT user p also downloads interested file fragments from neighbor BT users at the same time.

[0046] In step B of this example, BT user p selects a given number of BT users from the candidate BT user list to establish a...

Abstract

The invention discloses a P2P flow optimization method for enhancing network flow stability, which includes improvements to two key algorithms of the BT protocol: (1) BT neighbor user selection algorithm, which introduces the concept of flow slack to describe network flow state, according to the relative size of the traffic slack of the neighbor BT users, select the neighbor BT users according to the probability; (2) block / unclog algorithm, consider the traffic slack and transmission rate of the peer at the same time, and carry out dual-index selection, so that the BT protocol according to the network The current state actively adjusts its own traffic patterns. The invention can significantly enhance the stability of the network traffic matrix without sacrificing the performance of the BT protocol or even increasing the performance.

Description

technical field [0001] The invention relates to a BT traffic optimization method for enhancing the traffic stability of an Internet core network, and belongs to the technical field of computer network communication. Background technique [0002] A large number of studies have shown that Internet traffic has long-term correlation and burstiness. Internet core network traffic shows a stronger diurnal pattern, and has more typical cycle stationary characteristics (period is 24 hours, including several traffic smooth periods). The reasons mainly come from two aspects: First, the traffic of the core network is the aggregation of the traffic from the edge network (that is, the access network). The volatility is reduced and the stability is enhanced; secondly, the traditional Internet is dominated by web traffic, and web users have relatively stable day and night schedules and usage patterns every day. At present, the idea of ​​optimizing network energy consumption for the cycle-...
