Problems solved by technology

[0004] However, the above-mentioned existing technology has the following technical defects: since the solution is solved in a centralized manner, in the actual network, the solution to the optimal problem requires a lot of network state information, especially when the network scale expands, the information demand varies with the number of nodes As the number increases exponentially, the time it takes to collect information and calculate will increase sharply, and the amount of calculation is too large, making it difficult for network nodes to respond in real time, which brings great difficulty to the implementation of optimization schemes

Abstract

Embodiments of the invention provide a network optimization flow control method, device and system, wherein the method includes the steps that a data source node obtains a sub-data flow transmission path from the data source node to a sever node, and loads a first data flow amount onto the sub-data flow transmission path; a router node aggregates link prices of a plurality of links on the sub-data flow transmission path to obtain link aggregated price and feeds the link aggregated price back to the data source node; and the data source node obtains a second data flow amount according to the link aggregated price and server weight of the server node and loads the second data flow amount instead of the first data flow amount onto the sub-data flow transmission path. Embodiments of the invention greatly reduce calculation amount, and improves instantaneity of network optimization.

Description

technical field [0001] The invention relates to communication technology, in particular to a network optimization flow control method, device and system. Background technique [0002] Traditional Internet Service Providers (Internet Service Providers, referred to as: ISPs) mainly provide Internet connections. In terms of network optimization functions, they mainly solve traffic engineering (TE) problems, designate optimal paths for traffic, and minimize network congestion. The performance of the network is the optimization goal; while the content provider (Content Provider, referred to as: CP) mainly provides users with the content they need, provides users with reasonable resources, and solves the problem of server selection (SS). optimize the target. If the optimization of ISP and CP is combined to perform joint optimization (JO) of TE and SS, the optimal solution of the entire network can be obtained, and end-to-end delay can be minimized while minimizing link congestion...
