Methods and apparatus for improving network communication using ethernet switching protection |
摘要 |
A network layout between network elements and routers using network redundancy to improve reliability of network communication is disclosed. Upon detecting a link failure associated with a primary link between an access switch and a primary router by the access switch via a connectivity verification protocol, the access switch sends a message to the primary router indicating connection defect via the connectivity verification protocol such as IEEE 802.1 ag standard. After enabling protection switching mechanism to activate a secondary link between the access switch and a backup router for network communication, routing data streams are routed between the access switch and the router via the secondary link. In one aspect, the protection switching mechanism is operated in accordance with G.8031 under International Telecommunication Union ("ITU") standard. |
