Traffic engineering and server selection joint optimization method, system and related equipment

Abstract

The embodiment of the invention provides a traffic engineering and server selection joint optimization method, a traffic engineering and server selection joint optimization system and related equipment. An optimal solution is calculated by utilizing a small amount of information in a relatively shorter convergence time on the premise of not disclosing key bottom-layer network information to a content provider (CP) by an instant service provider (ISP). The method comprises that: a router determines each outgoing link bearing traffic belonging to the same user node; the router acquires optimal link weights of each outgoing link; and the router acquires determines a division strategy of the traffic belonging to the same user node on any outgoing link (u,v) in the outgoing links according to the optimal link weights and the traffic belonging to the same user node. In the method, the system and the related equipment, calculation is not required to be performed for a plurality of turns, so the amount of transmitted information is greatly reduced, the convergence time of the system is shortened, time consumption is low generally, and the traffic division determining efficiency is higher.

Description

technical field [0001] The invention relates to the communication field, in particular to a joint optimization method, system and related equipment of traffic engineering and server selection. Background technique [0002] An Internet Service Provider (ISP, Internet Service Provider) provides Internet connections through its own physical network. Since there are multiple paths between the source node and the destination node in the network topology, when the ISP plans to send certain traffic from a certain source node to a certain destination node, it needs to decide how to allocate traffic on each path. Traffic, so as to optimize the overall performance of the network (for example, delay, load balancing, etc.), the above-mentioned problems that ISPs need to solve are called Traffic Engineering (TE, Traffic Engineering) problems. [0003] A content provider (CP, Content Provider) utilizes an Internet connection to provide content services to its users, such as file, audio a...

But in many cases, such requirements are unreasonable for ISPs, especially when ISPs play a dominant role in cooperation; when the network contains multiple CPs, ISPs are unwilling to leak key underlying network information to each CP
