Embodiment Construction

[0035] To facilitate those skilled in the art to understand the technical content of the present invention, the content of the present invention will be further explained below in conjunction with the accompanying drawings.

[0036] First introduce the following two concepts:

[0037] Meeting point: the point where the input side is greater than or equal to 2.

[0038] Combination package: A combination package network N (V, E, S, T, A) includes the following properties:

[0039] 1) Finite directed acyclic multigraph G(V,E), where V represents the set of vertices in the graph G(V,E), and E represents the multiple set of directed edges in the graph G(V,E).

[0040] 2) No duplicate source node collection

[0041] 3) No duplicate destination node collection

[0042] 4) Limited packet symbol set A.

[0043] The vertices in the graph G(V,E) represent the communication nodes in the packet switching network, and the directed edges represent the error-free transmission channels between the commu...

Abstract

The invention discloses a method for selecting coding nodes in network control coding, which is applied in the field of network information transmission; firstly, the coding scheme of chromosomes is determined; Focus on selecting the optimal chromosome for optimization; in order to avoid the genetic algorithm from falling into locality, add some new members through the crossover and mutation links as part of the next iterative population; , has an impact on the final result.

Description

Technical field [0001] The invention belongs to the field of network information transmission, and particularly relates to the selection technology of coding nodes in network control coding. Background technique [0002] With the continuous enrichment of network services such as mobile social networking, cloud computing, and big data, the demand for network communication is increasing, which has brought huge capacity pressure on existing networks. Although upgrading network hardware and increasing network bandwidth can solve part of the pressure, it is usually accompanied by high upgrade costs. Therefore, the existing network information transmission technology has been difficult to adapt to the current demand for rapid and real-time transmission of information. [0003] The network control coding technology regards the entire network as a unified information transfer space, and combines the overall mastery and flexible control of the SDN / NFV technology over the entire network with...
