Embodiment
For making the technical problem to be solved in the present invention, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
To the present invention is directed in prior art based on the system of IGMP agreement once break down, the whole network of external test facility paragraph by paragraph examination can only be used, the method can disturb existing network and formality is loaded down with trivial details, the problem that cycle is very long, there is provided in a kind of detection method of multicast link, by sending control command to the network equipment on network link, the network equipment receiving control command joins request to sending multicast with oneself interconnected upstream network device, then the multicast service self received is monitored, and add up, the multicast protocol of judgement system and service condition, carry out fault location, multicast fault point, accurate location, be convenient to fix a breakdown in time, improve the efficiency detected.
As shown in Figure 1, the embodiment of the present invention provides a kind of detection method of multicast link, comprising:
Step 1, the control command that first network equipment sends according to server, to join request order to sending multicast with the upstream network device of this first network devices interconnect;
Step 2, described first network equipment receives described upstream network device and to join request the multicast service that order sends based on described multicast, and described multicast service is sent to described server.
In the above embodiment of the present invention, because equipment each in the system based on IGMP agreement can only know multicast protocol and the Link State of the equipment of oneself and downstream direction, in order to the state allowing each equipment can understand its upstream network device, multicast need be sent to described upstream network device to join request (Report) order, upstream network device is then according to described Report order, multicast service is sent to the network equipment interconnected with this upstream network device based on this IGMP agreement, concrete, described multicast service at least comprises the type of multicast protocol message, the data on flows of frequency and reception interval and group business stream.
Concrete, in the above embodiment of the present invention, can show whether this first network equipment (or link) breaks down according to the frequency of the multicast protocol message of the type of the multicast protocol message of this first network equipment, frequency and reception interval and default same type under normal circumstances, the comparison that receives interval; Or according to the data on flows of the group business stream of first network equipment and with the comparing of data on flows of the group business stream of its other interconnected network equipments can draw the on off operating mode of group business stream and the blocked state etc. of multicast link, the further localization of faults.
In the above embodiment of the present invention, the described multicast service that described first network equipment receives is that described upstream network device is sent by Internet igmpinternet.
In the specific embodiment of the invention, Internet igmpinternet and IGMP agreement, described multicast service be described upstream network device according to Report command request, issued from first network equipment described in trend by the related setting in IGMP agreement; What it was concrete issue process is not described specifically in embodiments of the present invention.
In order to better realize above-mentioned purpose, as shown in Figure 2, the embodiment of the present invention also provides a kind of detection method of multicast link, comprising:
