Problems solved by technology

In addition, the service implementation mechanism (especially the OAM implementation mechanism) of different SPTN equipment is different, and it is time-consuming and labor-intensive to develop a set of independent southbound interface adapters for each SPTN equipment.

[0041] On the basis of the above, a common AVL tree is maintained between related flow tables, and each flow table maintains a private AVL tree; While maintaining private and public two AVL trees.

[0042] If there is an increase in the flow table, when the identifiers of all related flow tables are set to be issued, the configuration information will be written to the hardware at one time.

[0043] If a flow table is deleted, delete the hardware configuration information immediately, and delete the private AVL tree of the flow table; delete the public AVL tree when all related flow tables are deleted.

[0045] Based on the first embodiment, this embodiment is for the flow table model of the PE node, which is divided into a packet forwarding processing model from the user side to the network side and a packet forwarding processing model from the network side to the user side, and the sequential configuration of the two models The order supports random, and the order of flow table configuration in the forwarding model also supports random.

[0046] Specifically reflected in the MPLS (Multi-Protocol Label Switching, multi-protocol label switching) flow table, MPLS L2 Port flow table, Vlan (Virtual Local Area Network, virtual local area network) of VPWS (Virtual Private Wire Service, virtual private line service) ) flow tables maintain a public AVL tree based on the business id, and each flow table maintains a private AVL tree. Each flow table maintains a Present information, which is used as an identifier to indicate whether the addition and deletion operation of the flow table ...

[0048] Based on the second embodiment, such as figure 1 As shown, in this embodiment, a service id (Tunnel_id) is bound to a flow table in the three types of flow tables of MPLS flow table, MPLS L2 Port flow table and Vlan flow table, that is, three different types of flow tables pass A business id is bound to each other, and the specific flow table adding process includes:

[0049] S101. Receive an instruction to add a flow table issued by the controller.

[0050] S102. Check the validity of the parameters in the flow table to determine whether the check is passed, if yes, go to S103; if not, go to S109.

[0051] S103. Encapsulate and insert the added flow table information into the private AVL tree of the flow table for software storage of the input information, and judge whether the insertion is successful, if yes, go to S104; if not, go to S109.

[0052] S104. Obtain the VPWS public AVL tree according to the input Tunnel_id, and judge whether the public AVL tree exists, ...

Abstract

A method and system for adapting a southbound interface, relating to the field of SPTN southbound interfaces, the method includes that when a flow table is added, after all relevant flow table entry information is configured, the configuration information is written into hardware at one time; any related When the flow table is deleted, the hardware configuration information is deleted immediately. The present invention can support random configuration sequence of relevant flow tables.

Description

technical field [0001] The present invention relates to the field of SPTN (Software Defined Packet Transport Network, software defined packet transport network) southbound interface, and specifically relates to a southbound interface adaptation method and system. Background technique [0002] In the face of future business development needs and the pressure of existing network operation and maintenance, the PTN (Packet Transport Network, packet transport network) network has a strong demand for further evolution, and the advanced concept of SDN (Software Defined Network, software defined network) and the reliability of PTN The integration of advantages such as security and high quality has become a huge driving force for the smooth evolution from PTN to SPTN. The SPTN network follows the requirements of manageability, controllability, and operation and maintenance, and has the advantages of large bandwidth, intelligence, and high reliability. [0003] The SPTN network archi...
