Embodiment Construction

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments.

[0030] figure 1 It is a typical networking usage scenario of the present invention. The network elements of each node form a network with Ethernet packet forwarding technology. In order to prevent loops and realize service aggregation, a tree-shaped hierarchical structure network is usually used.

[0031] figure 2 The present invention relates to the formation of the organizational structure of the exchange table items and the form of guiding message forwarding. Specifically, when a message enters a network element port, a table corresponding to "...

Abstract

The present invention discloses a packet access network and switching table entry deletion synchronizing method, and can solve the technical problem that switching table entry deletion methods of a network element that can trigger an entire switching path cannot meet requirements. The method includes the following steps: an originating network element initiates an switching table entry deletion action based on VLAN instances; and links and corresponds an LLDP extension TLV message carrying information of deleting switching table entry sent by a registered port in the VLAN instances; a registered port of a neighboring network element responds to the received synchronizing message of the switching table entry deletion, searches and deletes the switching table entry corresponding to the VLANinstances according to the information carried by the extended TLV, and links and corresponds to the LLDP extension TLV message carrying corresponding information of deleting switching table entry sent by the registered port in the VLAN instances. The method can actively trigger synchronous deletion of forward path switching table entries in the network, improves convergence speed of the forward path triggered by the switching table entry deletion, and reduces bandwidth occupied by invalid traffic in the network for a long period, and broadcast storms.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for deleting and synchronizing packet access network switching table items. Background technique [0002] The packet access network is a packetized mobile data backhaul network (IPRAN / PTN / UTN) currently being built by major domestic communication operators to meet the data communication needs of government and enterprise users while transforming the old transmission network. A dedicated transmission network specially constructed for enterprise users, so as to realize the solution that government and enterprise users can exclusively enjoy various high-quality communication services and information services. At the end of the network with complex access services, especially the user central office, a user-side access network based on Ethernet switching and forwarding technology is often deployed to meet multi-point and multi-service access, and then complete ...
