Abstract

The embodiment of the invention provides a link fault reporting method and a processing method, and a transmission node and a primary node. The reporting method comprises that: the transmission node on a looped network monitors a primary port of the transmission node so as to wait for receiving a message; if the transmission node does not receive any message on the primary port within a preset receiving period of time, a first link fault message is sent to the primary node on the looped network from a secondary port which is matched with the primary port so that the primary node judges that a link fault occurs in the looped network according to the first link fault message, wherein the receiving period of time is less than a transmission period of time of an entire link of the looped network. The situation that the link fault occurs in the looped network can be judged by the technical scheme under the condition that the primary node does not need to wait until time of a Fail timer of the primary node is out so that time for detecting that the link fault occurs in the looped network by the primary node is reduced.

Specific embodiment
Purpose, technical scheme and advantage for making the embodiment of the present invention are clearer, below in conjunction with the embodiment of the present invention In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described it is clear that described embodiment is The a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art The every other embodiment being obtained under the premise of not making creative work, broadly falls into the scope of protection of the invention.
The flow chart of the link failure report method that Fig. 1 provides for one embodiment of the invention.As shown in figure 1, the present embodiment Method include：
Transmission node on step 101, looped network monitors the master port of transmission node, with etc. message to be received.
If step 102 transmission node does not receive any message within the default reception time on master port, from The secondary port of master port pairing sends the first link failure message to the host node on looped network, so that host node is according to the first link Fault message judges that looped network occurs link failure；Wherein, the above-mentioned default reception time is less than the transmission of the whole piece link of looped network Time.
The looped network of the present embodiment uses RRPP technology in link layer, is the ether net topology that an annular connects.In looped network On, every equipment is all referred to as a node, and the role of node can be determined by the configuration of user.On looped network, have and only have One node is host node, and other nodes are transmission node.Host node is the promoter of looped network state active detecting mechanism, It is the policymaker executing operation after network topology changes.Transmission node is mainly responsible for monitoring the direct-connected RRPP link of oneself State, and link change is notified host node, then come how decision-making is processed by host node.But, for by physical port event Barrier, business board hardware fault and optical module receive and dispatch the situation of the port DOWN that light exception etc. leads to, and transmission node is possibly cannot Monitor, then link change cannot notify host node, lead to host node cannot know that looped network occurs link failure in time.
For the problems referred to above, the transmission node of the present embodiment pre-sets the reception time on its master port, during this reception Between be time needed for the message normally receiving autonomous node, when this reception time is less than the transmission of looped network whole piece link Between.The transmission time of looped network whole piece link refers under normal circumstances, and host node sends hello packet to from it from its master port Secondary port receives the maximum delay of hello packet.Based on this reception time, if transmission node did not received within this reception time To any message, then transmission node thinks that its master port breaks down, then from the secondary port active matched with master port to master Node transmission link fault message（It is designated as the first link failure message）, so that host node can know that looped network occurs link in time Fault.
For different transmission nodes, the reception time pre-setting on its master port can identical it is also possible to differ. In addition, the reception time pre-setting on master port can be according to looped network situation flexible configuration and adjustment.More preferred, The reception time pre-setting on master port is larger than the transmission cycle that host node sends hello packet.
The present embodiment is particularly suited for the situation that transmission node cannot monitor its direct-connected RRPP link failure, but equally It is also applied for the situation that transmission node can monitor its direct-connected RRPP link failure.That is, no matter link failure is Which kind of reason causes, and transmission node passes through to judge whether to receive message on the primary node within the default reception time this Mode all can successfully identify link failure.
In the present embodiment, transmission node by arranging connecing of the transmission time being less than looped network whole piece link for its master port Between the time receiving, if any message is not received on master port then it is assumed that master port breaks down within the default reception time, Therefore actively from the secondary port matched with master port to host node transmission link fault message so that host node is without when its Fail Timer timing time-out can determine that looped network occur link failure, decrease host node detect looped network occur link failure when Between, improve the promptness knowing that looped network occurs link failure.
In an optional embodiment, if transmission node does not receive within the default reception time on master port taken office What message, is not because the direct-connected RRPP link of the master port of the master port of transmission node or transmission node breaks down, and It is because the master port of the upstream node of transmission node or secondary port or the direct-connected RRPP link of master port or secondary direct port connection RRPP link breaks down and causes.In this case, the upstream node of transmission node is as in its default reception Any message do not received in the time on master port and actively to host node transmission link fault message（It is designated as the second link event Barrier message）, the second link failure message that the upstream node of such transmission node sends will be by transmission node to host node Forward, then, transmission node also can receive it after sending the first link failure message to host node on its master port The second link failure message that upstream node sends.If transmission node is after sending the first link failure message to host node Second link failure message of its upstream node transmission is received on its master port, then forwards the second link failure to host node Message, so that according to the first link failure message and the second link failure message, host node judges that looped network occurs link event simultaneously Barrier.
For host node, will successively receive two link failure messages.Link failure report in the present embodiment Literary composition meets the form of RRPP protocol massages, also includes the information such as target MAC (Media Access Control) address, source MAC, protocol type, mode field, According to the source MAC of Link State fault message, host node can identify that looped network is to there occurs link on which node Fault.A kind of form of link failure message is as shown in Figure 2.First link failure message and the second link failure message are come Say, the value of some fields is different, but form is identical.
At this, " upstream node of transmission node " being related in embodiment of the present invention is explained.Real in the present invention Apply in example, using the direction of the secondary port from the master port of host node to host node as reference direction, for any on looped network For two transmission nodes, by transmission node nearer for the master port apart from host node be known as apart from host node master port relatively The upstream node of remote transmission node；Accordingly, by the master port apart from host node, transmission node farther out is known as distance master The downstream node of the nearer transmission node of the master port of node.
In another optional embodiment, if transmission node receives within the default reception time on its master port Message, but it is not meant to that looped network does not occur link failure, also to distinguish the type going back message.If transmission node is default The reception time in receive on its master port this transmission node upstream node send the second link failure message, then with Sample can determine that looped network occurs link failure, then forwards the second link failure message to host node, so that host node being capable of root Judge that looped network occurs link failure according to the second link failure message.
Optionally, if transmission node receives host node transmission within the default reception time on its master port Hello packet, then illustrate that the link from the master port of host node to transmission node does not break down, transmission node also can continue Continue and forward hello packet to host node, if host node successfully receives hello packet from its secondary port, illustrate that whole piece link is Health, do not break down；If what host node received is link failure message, the pair from transmission node to host node is described Link between port may have occurred fault.
For any transmission node on looped network, its processing mode is all identical, therefore the present embodiment is only transmitted with one It is illustrated as a example node.
Transmission node by for its master port setting less than looped network whole piece link transmission time the reception time, either The situation of any message was not received within the default reception time on master port, or receives within the default reception time The situation of the second link failure message sending to its upstream node, can make host node determine without when its Fail timer When time-out can determine that looped network occur link failure, decrease host node detect looped network occur link failure time, improve Know that looped network occurs the promptness of link failure.
In an optional embodiment, transmission node on looped network monitors the master port of transmission node, with etc. report to be received The embodiment of literary composition includes：Transmission node opens fault detect timer on its master port, in the timing of fault detect timer Terminate before monitor master port, with etc. message to be received；Wherein, the timing length of this fault detect timer is above-mentioned default connects Between the time receiving.
Specifically, transmission node gives tacit consent to startup separator detection timer on its master port, in order to default to connect to above-mentioned Carry out timing between the time receiving.If transmission node receives message before fault detect timer timing terminates on master port（Phase When message being received on master port in above-mentioned within the default reception time）, illustrate that the direct-connected RRPP link of this master port is Normally, thus closing fault detection timer, and forward, to host node, the message that receives.Here message is probably host node From its master port send hello packet it is also possible to transmission node upstream node send the second link failure message.
If transmission node does not receive any message after fault detect timer timing terminates on master port（Quite In above-mentioned, any message was not received within the default reception time on master port）, now transmission node is except from secondary port Outside sending the first link failure message to host node, fault detect timer can also be restarted to continue to monitor this main side Mouthful, and until restarting till the number of times of this fault detect timer reaches default frequency threshold value.Wherein, transmission node weight New startup separator detects timer to continue to monitor the situation that master port is to break down in the upstream node of transmission node Under, wait the second link failure message that the upstream node of transmission node to be received sends.
Generally, the propagation delay time from the upstream node of transmission node to transmission node would generally be in certain time range Interior, therefore, it can maximum according to propagation delay time and the frequency threshold value restarting fault detect timer is set.Illustrate, If this frequency threshold value could be arranged to 1 that is to say, that not receiving transmission node yet within two default reception times The second link failure message that upstream node sends, then can directly judge is the master port of transmission node or master port is direct-connected RRPP link failure, then can no longer restart fault detect timer, also imply that and do not continue to monitor this master port.
Here illustrate, above-mentioned restart fault detect timer in the case of, if transmission node fault detect timing Device timing does not receive any message after terminating on master port yet, then can send the first link failure report without to host node Literary composition, only when receiving the second link failure message of its upstream node transmission, the second link failure message is transmitted to master Node.
Present embodiment can be realized in conjunction with the respective embodiments described above, in the present embodiment, the first link failure message Can include：The identification information of the master port of the identification information of transmission node and transmission node.The identification information of transmission node removes It is outside the MAC Address of transmission node, can also be that other is more beneficial for the information of fault point position, for example, can include The IP address of transmission node, title of transmission node etc..Accordingly, the identification information of the master port of transmission node can also be just In the information of the position of fault point, for example, can include the title of master port, the port numbers of master port, the port of master port Type etc..
In addition, the second link failure message can also include：The identification information of the upstream node of transmission node and transmission section The identification information of the master port on the upstream node of point.In the same manner, the identification information of the upstream node of transmission node is except being transmission Outside the MAC Address of the upstream node of node, can also be that other is more beneficial for the information of fault point position, for example, can wrap Include the IP address of the upstream node of transmission node, title of the upstream node of transmission node etc..Accordingly, the upstream of transmission node The identification information of the master port of node can also be easy for the information of the position of fault point, for example, can include master port Title, the port numbers of master port, port type of master port etc..
Based on above-mentioned, for host node, if only receiving the first link failure message, can be directly according to first The identification information of the master port of the identification information of the transmission node that link failure message includes and transmission node, determines on looped network The position of trouble point, the position of this trouble point is the master port of transmission node or the RRPP link that master port is direct-connected；If first After receive the first link failure message and the second link failure message, then can first carry according in each link failure message The identification information of transmission node determine the upstream-downstream relationship of transmission node, then according to being in most upstream in upstream-downstream relationship The identification information that carries of link failure message of transmission node determine the position of ring network fault point.For the first link failure report For literary composition and the second link failure message, host node may determine that needs determine ring network fault according to the second link failure message The position of point.
In conjunction with the form of link failure message shown in Fig. 2, the first link failure message can use any one shown in Fig. 2 Reserved field carrying the identification information of the identification information of transmission node and the master port of transmission node, in the same manner, the second link therefore Barrier message can carry the identification information of upstream node and the transmission of transmission node using any one reserved field Fig. 2 Suo Shi The identification information of the master port on the upstream node of node.Or, transmission node or its upstream node can also be by links Fault message is extended, and adds new field to carry above- mentioned information.
In the present embodiment, each transmission node on looped network is by pre-setting the reception time in its master port, When not receiving any message in the default reception time on master port, active is to host node transmission link fault message, and Carry the identification information of transmission node and the identification information of master port in link failure message, can not only make host node without etc. Can determine that looped network occurs link failure to its Fail timer timing time-out, decrease host node and looped network generation link is detected The time of fault, host node can also be made simultaneously to be accurately positioned out the trouble point on looped network, be conducive to carrying out malfunction elimination, favorably Maintainability in lifting looped network.
