Abstract:
A method, system and controlling bridge (CB) for acquiring port extension (PE) topology information, and a method and system for processing an upstream port, wherein, the method for acquiring the port extension (PE) topology information includes: a CB receiving a link layer discovery protocol (LLDP) message sent by the PE, and perceiving an attachment of the PE; the CB receiving Extended Port Create message sent by the PE, and instantiating corresponding instantiated ports inside the CB. By adopting the above-mentioned technical scheme, the topology information of the PE connected to the CB can be obtained and a channel for forwarding data can be established, effectively.
Abstract:
This disclosure discloses a method for implementing protection group overlay and a method for implementing Ethernet protection switching based on the protection group overlay. The method for implementing Ethernet protection switching based on the protection group overlay comprises: when the fault of TESI is detected by multiple IPG which protect the same TESI, only one IPG of the multiple nested IPGs performs protection switching. This disclosure further discloses a system for implementing Ethernet protection switching based on the protection group overlay, comprising a protection switching performing unit, configured to when a fault of a TESI is detected by multiple IPGs which protect the TESI, only one IPG of the multiple nested IPGs performing protection switching. Application of the method and system of this disclosure implements protection for key protected path through protection group overlay, and can achieve effects of saving network resource and increasing utilization rate of network resource.
Abstract:
The present invention discloses a method for detection of Ethernet segment protection, and this method includes: configuring a detection point in two segment protection domains with a shared link; configuring a joint monitor group on the shared link of said two segment protection domains; and judging whether the configured detection point and the joint monitor group receive a Continuity Check Message (CCM) in a certain period, if the CCM message is received, determining a detected segment corresponding to this CCM message is normal; if the CCM message is not received, determining the detected segment corresponding to this CCM message has a fault. The present invention further discloses a system for detection of Ethernet segment protection, including: a detection point configuration unit, a joint monitor group configuration unit and a judgment unit. The method and system of the present invention can solve the problem of the segment protection in the case of the multi-node fault and greatly improve the network performance.
