Method For Implementing on-Ring Process, Off-Ring Process and Data Forwarding in Resilience Packet Data Ringnet and a Network Device Thereof

摘要

An inserting and copying processing method for implementing an L2/L3 compatible RPR network is provided. The inserting processing method includes: encapsulating an Ethernet data frame with local mode or remote mode according to whether the source and destination MAC addresses of the Ethernet data frame may be found in the ring station MAC address table or in the correspondence table of host MAC address and RPR station, and whether the destination address of the Ethernet data frame is a unicast address or a non-unicast address. The copying processing method includes: recombining the RPR data frame into an Ethernet data frame according to the forwarding mode of the RPR data frame, and learning the correspondence relationship between source host address and RPR station address according to the Flooding flag and the forwarding mode of the RPR data frame. This invention also provides a data forwarding method and a network apparatus.
