Method for protecting uplink plate card of carrier-grade broadband access equipment

Abstract

The invention relates to a method for protecting an uplink plate card of carrier-grade broadband access equipment, in particular to the protection of the uplink plate card, which comprises the detailed steps: step 1, a master port is set as forwarding state and a slave port is set as blocking state; and step 2, the master port continues forwarding data if the master port works normally according to the detection and waits for the next detection; a main link and a standby link are switched if the link of the master port does not work normally according to the detection and the slave port is set as forwarding state; then the information of the master port is copied to the slave port so as to realize rapid the main / standby switch, and finally the master port is set as blocking state. The method for protecting the uplink plate card of the carrier-grade broadband access equipment realizes rapid switch within a plurality of milliseconds by simple configuration and low cost in a networking environment with double uplink, protects the completeness of the information and meets the requirements of the high service quality by users.

Description

technical field [0001] The invention relates to the protection of uplink boards, in particular to a method for protecting uplink boards of telecom-grade broadband access equipment. Background technique [0002] As the society's dependence on information increases, the influence of the network on people's daily life is also increasing. Once the network fails, it will cause great impact and loss to the normal operation of the society. How to build a secure bearer network has become the most practical issue facing every operator, and whether it can provide a stable and mature protection mechanism also determines the success or failure of its multi-service and emerging services. [0003] In recent years, with the deployment of more and more LAN-based voice and multimedia applications, the performance of the underlying LAN infrastructure has become critical. Availability of every network component is essential, not only the WAN link, ISP and routed network should be redundant, b...

Problems solved by technology

[0011] No matter what tasks the ports take on, they can become alternative ports or standby ports that provide connectivity in case of failure. RSTP ensures that after a switch port or LAN fails, the network connection can be restored quickly, enabling reconfiguration and recovery. The service time is below the second level, but this still cannot meet the needs of high-end Ethernet switches at the core of carrier-class networks

[0012] Although the ring network solution can improve the convergence performance, it has great limitations in networking. For dual uplink networking, the configuration of intersecting rings in the same domain is required, which is more complicated.
