Detailed description of the invention
In order to realize the object of the invention, the core concept that the present invention adopts is: when transmission equipment and opposite end reception equipment room exist multiple communication links, transmission equipment sends detection messages according to default period 1 timing, and copies to described detection messages to receive with opposite end and send on all links of equipment communication simultaneously；Opposite end receives equipment according to adding up the detection messages quantity received in each of the links default second round, and when terminating described second round, the detection messages quantity that every communication link receives is collected；Whether opposite end receives the detection messages quantity in each of the links that equipment judges to add up in the detection cycle more than the threshold value Ccmp set, if it is, judge that this Link State is normal, otherwise, then judges this communication link fails。By the present invention, the multilink fault testing mechanism of LA Management Room is simple, and overhead is little。
For making technical solution of the present invention clearly and understanding, described in detail below in conjunction with the specific embodiment of the invention。As in figure 2 it is shown, be the method flow diagram of a kind of multilink fault provided by the invention detection。Wherein said method is applied to transmission equipment and opposite end receives equipment room and there is the situation of multiple communication links, with reference to Fig. 1, for the network equipment A communication direction to network equipment B, the invention mainly comprises the following steps:
Step 1, transmission equipment send detection messages according to default period 1 timing, and copy to described detection messages to receive with opposite end and send on all links of equipment communication simultaneously。
In the application scenarios shown in Fig. 1, network equipment A sends detection messages by cycle t timing, and described detection messages is copied to and send on all communication links between network equipment A and network equipment B simultaneously。Wherein detection messages, it is possible to adopt the conventional heartbeat message of prior art or hello packet etc., be not repeated herein。
What detection messages sent on all communication links between network equipment A and network equipment B simultaneously is implemented as:
If each of the links has a sending module, then first detection messages is copied into many parts by software or specialized hardware, then transfers to each communication link sending module each to send。
If multiple communication links shares a sending module, then sending module adopts the mode of circulation to send on every communication link。
Step 2, opposite end receive equipment according to adding up the detection messages quantity received in each of the links default second round, and when terminating described second round, the detection messages quantity that every communication link receives are collected。
It is preferred that in embodiments of the present invention, described second round is the integral multiple x of period 1。Specifically, under application scenarios as shown in Figure 1, network equipment B adds up, by cycle T (T=xt, namely T is the integral multiple of t), the detection messages quantity received in each of the links。Counting is designated as C1, C2, C3 respectively ... Cn。
The detection messages quantity judged on step 3, opposite end reception equipment in the detection cycle in each of the links of statistics, whether more than the threshold value Ccmp set, if it is, judge that this link is that state is normal, otherwise, then judges this communication link fails。
Specifically, under application scenarios as shown in Figure 1, in order to enable effectively to judge whether certain communication link exists fault, need to set on network equipment B further a threshold value Ccmp, wherein said threshold value should be less than x, preferably, in embodiments of the present invention, set Ccmp < (1/2) x, within the detection cycle, if the counting of certain communication link is more than Ccmp, then judge that this communication link state is normal, otherwise, then judge that this link exists fault, and by corresponding fault alarm reporting to webmaster personnel。
In order to realize the object of the invention, further, carrying out before this step judges communication link fails, described opposite end receives equipment and also needs to judge detecting whether effectively in described second round。The process of implementing is: opposite end receives equipment and finds out detection messages maximum count Cmax from the detection messages quantity of all links received, and judge that whether the detection messages maximum count Cmax that receives is: Cmin≤Cmax≤x, if, then this detection cycle is effective, enter step 4, otherwise, abandon this detection cycle, returning step 2, wherein said Cmin presets as required。
Under application scenarios as shown in Figure 1, when cycle T terminates, network equipment B finds out a maximum count Cmax from C1-Cn, as Cmin≤Cmax≤x, then it is assumed that the detection in this cycle is effective。Otherwise, the detection in this cycle is invalid, returns step 2 and directly starts the next detection cycle。Wherein Cmin can dynamically regulate as required in advance, it is preferred that, in embodiments of the present invention, minimum detection packet counting Cmin is set as (1/2) x≤Cmin < x。
Further, described threshold value Ccmp should be set as: Ccmp < Cmin。
