Description
Technical field
The present invention relates to the IP network technical field, relate in particular to a kind of method, system and equipment of protecting ring network link.
Background technology
Rapid ring protection protocol (Rapid Ring Protection Protocol; RRPP) be a link layer protocol that is specifically applied to Ethernet ring; when it can link failure occur on Ethernet ring, enable backup link rapidly to recover the communication path between each node on the looped network.
Use the Ethernet ring of RRPP agreement mainly to be made of a plurality of nodes, one of them is a host node, and other nodes are transmission node, and two ports of host node on ring are divided into Primary port and secondary port.Loop occurs for fear of looped network, the secondary port of host node is in closed condition usually, and secondary port can not the transmitting and receiving service message, but can receive and dispatch protocol massages.
In order to detect the link failure in the looped network, host node cycle ground sends agreement (HELLO) message of ring from master port, encircling under the complete situation, host node can receive the HELLO message that oneself sends on secondary port in some cycles, host node thinks that looped network is in good working condition like this, then keeps secondary port to be in closed condition to guarantee not have loop; If host node does not receive the HELLO message that oneself sends at secondary port in some cycles, think that then looped network is in malfunction, host node can open auxiliary port make it can the transmitting and receiving service message, send other transmission nodes renewals of message notifying simultaneously and transmit, data flow then switched on the backup link after transmission node upgraded and transmits.
In case the secondary port of host node receives the HELLO message that oneself sends, then think the looped network state that regains one's integrity, close secondary port at once, and send message and notify other nodes to refresh to transmit, transmission node upgrades to be transmitted the back data flow and switches back again on the original link.
In addition, when the link between node on the looped network or direct connected node breaks down, can trigger the down incident of node port, this node can initiatively send fault (link_down) message to host node immediately, when host node receives the fault message, think that also looped network is in malfunction, at once the open auxiliary port, send other transmission nodes renewals of message notifying simultaneously and transmit, data flow switched on the backup link after transmission node upgraded and transmits.
If fault recovery, the port of malfunctioning node can get up by UP, at this moment malfunctioning node can block this port temporarily, but this port can also transparent transmission RRPP protocol massages, host node can penetrate interim port blocked from the HELLO message that master port sends, in case the secondary port of host node receives the HELLO message that oneself sends, then think the looped network state that regains one's integrity, close secondary port at once, and send message and notify other nodes to open interim port blocked to refresh simultaneously and transmit, transmission node upgrades to be transmitted the back data flow and switches back again on the original link.
As seen, in the looped network that uses the RRPP agreement, host node does not receive the protocol massages that master port sends or receives two kinds of situations of fault message that transmission node sends at some cycles according to secondary port and detects the loop network link fault.
When certain bar link of transmission node breaks down, the forwarding chip fault of transmission node for example, caused the situation of one-way passage, promptly the master port from host node opens circuit toward the secondary port direction communication of host node, backward channel, perhaps the secondary port from host node opens circuit backward channel toward the master port direction communication of host node.At this moment when host node detects link failure, can the open auxiliary port make it can the transmitting and receiving service message.But owing to being exactly path originally from secondary port toward the master port direction or from master port toward secondary port direction, loop will appear in the open auxiliary port, the serious consequence that finally causes whole net to be paralysed.
Shown in Figure 1A, by node 1, node 2, node 3, in the looped network that is in normal condition that 4 four switches of node are formed, each switch has all enabled RRPP, and node 1 is set to host node, P is the master port of host node, and S is the secondary port of host node, and secondary port is closed in case the stop ring road;
Shown in Figure 1B, suppose that node 4 breaks down, unusual etc. as forwarding chip, cause node 3 obstructed, and node 4 is a path to the link of node 3, the single-pass phenomenon that node 4 arrives node 3 occurs to the link of node 4.When detecting looped network, host node is in malfunction, open auxiliary port S at once then, and this moment, secondary port S just can the transmitting and receiving service message, so had occurred the loop from secondary port to the master port direction in the looped network, and the serious consequence that whole net is paralysed may occur.

Embodiment
The method of a kind of protecting ring network link that the embodiment of the invention provides; in the method; host node sends protocol massages respectively from Primary port and secondary port; when not receiving protocol massages in the certain hour after Primary port and secondary port is sending protocol massages; host node is just opened secondary port; otherwise,, keep secondary port to be in closed condition for avoiding occurring loop.
The embodiment of the invention provides a kind of method of protecting ring network link; be applied to use in the ethernet ring network of RRPP agreement, this looped network mainly is made of a plurality of nodes, and one of them is a host node; other nodes are transmission node, and two ports of host node on ring are divided into Primary port and secondary port.Loop occurs for fear of looped network, the secondary port of host node is in closed condition usually, and secondary port can not the transmitting and receiving service message, but can receive and dispatch protocol massages.
Referring to Fig. 2, the specific implementation flow process of method that the embodiment of the invention provides is as follows:
Step 201: host node sends protocol massages from Primary port and secondary port respectively;
In the looped network that uses the RRPP agreement, in a single day host node enables RRPP, just send protocol massages respectively from Primary port and secondary port, cycle at regular intervals later on, host node all sends protocol massages respectively from Primary port and secondary port, when sending protocol massages, for Primary port and secondary port starts timer.Wherein, the protocol massages that sends from master port under the complete situation of looped network, can arrive the secondary port of host node at last by each transmission node in the looped network; After master port sent protocol massages, if within a certain period of time, secondary port did not receive this protocol massages, and then host node is thought link occurs fault.Equally, the protocol massages that sends from secondary port is under the complete situation of looped network, can arrive the master port of host node by each transmission node in the looped network at last, if within a certain period of time, master port does not receive this protocol massages, and then host node is also thought link occurs fault.
Step 202: when not receiving protocol massages in the certain hour of host node after Primary port and secondary port is sending protocol massages, just secondary port is opened;
This step comprises following three kinds of situations:
When not receiving protocol massages in the certain hour of master port after sending protocol massages, host node is thought link occurs fault, but open auxiliary port immediately not, but judge at first whether secondary port does not receive protocol massages in the certain hour after sending protocol massages yet, if, then mean and do not have one-way passage in the looped network, the detected link failure of host node is not a single-channel fault, this moment, host node was just opened secondary port, make it can the transmitting and receiving service message, send other transmission nodes renewals of message notifying simultaneously and transmit, data flow then switched on the backup link after transmission node upgraded and transmits; Otherwise mean the one-way passage that exists in the looped network from master port to secondary port direction, the detected link failure of host node is a single-channel fault, and do not open secondary port for fear of loop occurring this moment, but keep secondary port to be in closed condition, only with the timer zero clearing;
When not receiving protocol massages in the certain hour of secondary port after sending protocol massages, host node is thought link occurs fault, but open auxiliary port immediately not, but judge at first whether master port does not receive protocol massages in the certain hour after sending protocol massages yet, if, then mean and do not have one-way passage in the looped network, the detected link failure of host node is not a single-channel fault, this moment, host node was just opened secondary port, make it can the transmitting and receiving service message, send other transmission nodes renewals of message notifying simultaneously and transmit, data flow then switched on the backup link after transmission node upgraded and transmits; Otherwise mean the one-way passage that exists in the looped network from secondary port to the master port direction, the detected link failure of host node is a single-channel fault, and do not open secondary port for fear of loop occurring this moment, but keep secondary port to be in closed condition, only with the timer zero clearing;
When host node receives the link failure message that transmission node sends, also open auxiliary port immediately not, but judge that at first whether Primary port and secondary port does not receive protocol massages in the certain hour after sending protocol massages, if, then mean and do not have one-way passage in the looped network, the detected link failure of host node is not a single-channel fault, this moment, host node was just opened secondary port, make it can the transmitting and receiving service message, send other transmission nodes renewals of message notifying simultaneously and transmit, data flow then switched on the backup link after transmission node upgraded and transmits; Otherwise mean and exist from master port to secondary port direction in the looped network or one-way passage from secondary port to the master port direction, the detected link failure of host node is a single-channel fault, this moment is for fear of loop occurring, secondary port is not opened, but keep secondary port to be in closed condition, only with the timer zero clearing.
In this step, described certain hour, can be provided with and change, such as: can in host node, be respectively Primary port and secondary port timer is set, so, can also not receive protocol massages by master port when the timer expiry of master port, judge in the certain hour of master port after sending protocol massages and do not receive protocol massages, equally, can also not receive protocol massages by secondary port when the timer expiry of secondary port, judge in the certain hour of secondary port after sending protocol massages not receive protocol massages; Certainly, the Primary port and secondary port of host node can a shared timer, in this case, also do not receive protocol massages by master port when this timer expiry, judge in the certain hour of master port after sending protocol massages and do not receive protocol massages, equally, can also not receive protocol massages, judge in the certain hour of secondary port after sending protocol massages not receive protocol massages by secondary port when this timer expiry.
Step 203: after secondary port opened, when the master port of host node or secondary port receive the protocol massages that transmission node sends, close secondary port;
Here, after secondary port opened, when Primary port and secondary port receives protocol massages simultaneously, the looped network state that regains one's integrity, for preventing loop, need close secondary port, and send message and notify other transmission nodes to refresh to transmit, transmission node upgrades to be transmitted the back data flow and switches back again on the original link.And when master port or one of them port of secondary port receive protocol massages, owing to have only a port to receive protocol massages, this moment the looped network state that do not regain one's integrity, but communications loop has appearred, cause more serious consequence such as broadcast storm for fear of loop, also need secondary port shutdown, and send message and notify other transmission nodes to refresh to transmit.

Shown in Fig. 4 A, suppose that node 3 and node 4 break down, cause node 3 obstructed to the link of node 3 to node 4 and node 4.When host node detects looped network and is in malfunction, whether be single-channel fault in order to distinguish this fault, judge at first whether Primary port and secondary port does not all receive protocol massages at certain hour in the cycle.Because node 3 is all obstructed to the link of node 3 to node 4 and node 4, there is not one-way passage in the looped network, this moment, master port and secondary end did not all receive protocol massages, therefore the detected link failure of host node is not a single-channel fault, so host node is opened its secondary port, make it can the transmitting and receiving service message, send other transmission nodes of message notifying simultaneously and upgrade and transmit, transmission node upgrades to be transmitted the back data flow and then switches on the backup link.At this moment, between four nodes, set up the communication path of service message transmission again, shown in Fig. 4 B.
Referring to Fig. 5 A, the embodiment of the invention also provides a kind of system of protecting ring network link, and this system comprises: comprise the host node equipment 501 of master port P and secondary port S, be used for sending protocol massages from described master port and described secondary port to transmission node equipment respectively; When described master port and described secondary port do not receive the protocol massages that transmission node equipment sends in described certain hour after sending protocol massages, open described secondary port; Transmission node equipment 502 is used to receive the protocol massages that described master port or described secondary port send, and sends this protocol massages to described secondary port or described master port.
Referring to Fig. 5 B, host node equipment 501 also comprises transmitting element 5011 and fault detection unit 5012, and wherein, transmitting element 5011 is used for sending protocol massages from described master port and described secondary port to transmission node equipment respectively; Fault detection unit 5012 when being used at described master port and described secondary port not receiving in the certain hour after transmitting element sends protocol massages the protocol massages that transmission node equipment sends, is opened described secondary port.
Transmitting element 5011 is used for that the cycle is sent protocol massages from described master port and described secondary port to transmission node equipment respectively at regular intervals.
Referring to Fig. 6, the embodiment of the invention also provides a kind of host node equipment, this equipment comprises master port P and secondary port S, can be applied in the system of protecting ring network link, link to each other with transmission node equipment, this equipment also comprises transmitting element 601 and fault detection unit 602, wherein, transmitting element 601 is used for sending protocol massages from described master port and described secondary port to transmission node equipment respectively; Fault detection unit 602 when being used at described master port and described secondary port not receiving in the certain hour after transmitting element sends protocol massages the protocol massages that transmission node equipment sends, is opened described secondary port.
Transmitting element 601 is used for that the cycle is sent protocol massages from described master port and described secondary port to transmission node equipment respectively at regular intervals.
This equipment further comprises fault recovery unit 603, is used for closing described secondary port when described master port or described secondary port receive the protocol massages that transmission node equipment sends.
In the present invention, host node can not receive protocol massages in the certain hour after sending protocol massages by master port or secondary port, perhaps detect link failure by receiving the fault message that transmission node sends, both can detect link failure, can also detect link failure from secondary port to the master port direction from master port to secondary port direction.But, after host node detects link failure, only under the situation that definite this link failure is not a single-channel fault, just enable backup link, the open auxiliary port, because the open auxiliary port can make looped network communications loop occur when single-channel fault, communications loop then may cause the serious adverse consequences such as broadcast storm.Here,, illustrate that then this link failure is not a single-channel fault if Primary port and secondary port does not all receive the protocol massages that transmission node is sent in the certain hour after sending protocol massages, can the open auxiliary port; If do not receive the protocol massages that transmission node is sent in the certain hour of one of them port of Primary port and secondary port after sending protocol massages, and receive the protocol massages that transmission node is sent in the certain hour of another port after sending protocol massages, illustrate that then this link failure is a single-channel fault, not the open auxiliary port.
This shows, adopt the present invention, can guarantee to occur under the situation of single-channel fault at the link of ethernet ring network, host node can not enabled backup link and secondary port is opened, thereby guaranteed communications loop can not occur in the looped network, and then avoided because the serious adverse consequences that communications loop caused such as broadcast storm.
