Description of drawings
Fig. 1 is an ethernet ring network structural representation of the present invention.
Embodiment
The common trait of ethernet ring network agreement: when the topology of looped network or segment link changes, agreement will send TCN (Topology Change Notify by each node on ring or segment link, topology change notification) message, after node on ring or the segment link is received the TCN message, node need refresh FDB (ForwardingDatabase transmits) table.Each node can perceive the change in topology of ring (perhaps segment link) on the ring.Although the TCN message format that each looped network agreement realizes is generally different; But nearly all ethernet ring network agreement is when network topology changes, and Control Node all will go up other node to ring and send the TCN message, and the node on the ring receives that the TCN message all will upgrade the FDB table.
Ethernet ring network structural representation of the present invention as shown in Figure 1, N1 is existing ethernet ring network, N is a subring network to be accessed, wherein
E1, E2: be two edge ports of N1.
EC, EA: be two upstream nodes of N.
UPLINK1: the uplink port of upstream node equipment EC.
UPLINK2: the uplink port of upstream node equipment EA.
E_C: the edge port of upstream node EC.
E_A: the edge port of upstream node EA.
N1 operation looped network agreement B, each node operation looped network agreement B on the ring is so edge port E1 and E2 also move looped network agreement B; N operation looped network agreement A.In order to realize that N inserts N1, guarantees that two continuous looped networks keep the intercommunication of data, will make edge port EC and the EA of segment link by upstream node between N or EC and the EA insert N1, need:
Step a, the node that subring network N to be accessed is set are formed level part section link; The edge port E_C of upstream node EC and upstream node EA and other node operation looped network agreement A on E_A and the segment link; UPLINK1 and UPLINK2 do not move looped network agreement A as uplink port, but the TCN message of uplink port transmitting-receiving and explanation looped network agreement B need be set;
The uplink port of step b, the edge port E1 that existing ethernet ring network N1 is set and E2 and subring network uplink node to be accessed is consulted, and makes E1 and E2 be in and can transmit data mode.
When network topology changed, data took place to switch fast, two necessary perception network topology change each other mutually of looped network; After the N topology changes, need each node of N1 to refresh the FDB table; After the N1 network topology changes, also need each node of N to refresh the FDB table, can satisfy data like this and switch fast.
When the network topology of N1 changed, N1 sent out looped network agreement B form TCN message from edge port E1 and E2, and general looped network agreement is supported this function.After the upstream node EC of N and node EA receive this TCN; Need do two things: the one, the TCN of structure looped network agreement A issues each node of N; The 2nd, refresh uplink port UPLINK1 and UPLINK2 and the edge port E_C and the E_A of upstream node.
When the N network topology changed, the TCN message of EC and EA structure looped network agreement B was issued N1, and will refresh the FDB table of uplink port UPLINK1 and UPLINK2.After the edge port E1 of N1 and E2 receive TCN, also need to do two things: the one, the FDB that refreshes edge port E1 and E2 shows; The 2nd, send out TCN to each node of N1, general looped network agreement is all supported this function.
