Problems solved by technology

[0003] Applying SDN to IP backbone network flow control, SDN can theoretically configure routing paths for each service flow independently. However, due to the huge number of IP backbone network services, SDN needs to maintain and deliver a large number of flow entries, and switches also need to Store a large number of flow entries
In addition, due to the wide geographical distribution of IP backbone network switches / routers, the configuration and reconfiguration of routing paths take effect slowly

[0027] For the convenience of description, first explain the relevant professional terms appearing in the specific implementation:

[0028] SDN (Software-Defined Network routing): Software-Defined Network;

[0029] IP (Internet Protocol): network protocol;

[0030] APP (Application): application;

[0031] MPLS (Multi-Protocol Label Switching): Multi-protocol label switching;

[0032] figure 1 It is an architecture diagram of a specific implementation manner of the SDN flow control system based on sub-path serial connection of the present invention.

[0033] In this embodiment, as figure 1 As shown, an SDN flow control system based on sub-path serial connection of the present invention includes: a flow control APP module, an SDN controller and network base station facilities.

[0034] The flow control APP module also includes a database and a flow control module, which are mainly used to optimize the routing path of the business flow and output the target routing path, and then the flow ...

Abstract

The invention discloses an SDN flow control system based on sub-path concatenation. By introducing sub-paths, the path is transformed into the form of sub-path concatenation, so that the network can flexibly control network traffic. At the same time, due to the introduction of sub-paths, when the network changes, it is only necessary to modify the sub-path sequence of the incoming edge router to realize the control of the network, improve the path update speed, and the introduction of sub-paths reduces the need to install on the switch. The number of forwarding flow tables improves scalability.

Description

Technical field [0001] The invention belongs to the field of network communication technology, and more specifically, relates to an SDN flow control system based on sub-path serial connection. Background technique [0002] SDN separates the network control plane from the data forwarding plane, manages network resources from a global network perspective and global flow status information, realizes flexible control of network traffic, improves network resource utilization, simplifies network management, and reduces operation and maintenance costs. Thereby promoting network innovation and evolution. [0003] Applying SDN to IP backbone network flow control, SDN can theoretically configure a separate routing path for each service flow. However, due to the large number of IP backbone network services, SDN needs to maintain and issue a large number of flow entries, and switches also need Store a large number of flow table entries. In addition, due to the wide geographical distribution ...
