Description

The method of fault recovery and controller

Technical field

Background technology

In IP-over-Optical network model, procotol (Internet Proticol, IP) layer photoreactive layer controlled respectively independently of each other, not dynamic collaborative between two two-layer control planes.

While breaking down in IP-over-Optical network, what generally take is the mode based on holdoff-timer.Preferentially carry out photosphere recovery, photosphere recovers unsuccessfully or after overtime, carries out the recovery of IP layer again.The mode of this holdoff-timer generally realizes by timer being set at IP layer.In IP-over-Optical network, break down, and this fault causes the time of service disconnection to surpass at timer after set time period, IP layer just can carry out path recovery.

For example, when the photosphere in IP-over-Optical network breaks down, a kind ofly may be: at timer, in set time period, the control plane of photosphere does not complete photosphere and recovers.So at timer after set time period, just further by the control plane of IP layer, carry out the recovery of IP layer.

And wherein, the control plane of photosphere does not complete the reason that photosphere recovers, be likely that the set time period of timer is too short, cause the control plane of photosphere not have time enough to complete photosphere recovery.But if the set time period long enough of timer, when the control plane ability of photosphere does not complete photosphere recovery, the control plane of IP layer carries out the recovery of IP layer again after also needing to wait for the sufficiently long time so.Can cause the overlong time of fault recovery like this, also further cause the overlong time of service disconnection.

Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.

Fig. 1 is the schematic diagram of IP-over-Optical network.Solid box shown in Fig. 1 represents IP layer, and dotted line frame represents photosphere.Node 101 to 104 is wherein the node of IP layer, the node that node 105 to 107 is photosphere.

Suppose, business node 101 in the IP-over-Optical network shown in Fig. 1 to the actual transmission paths of node 104 is: node 101 → node 102 → node 105 → node 107 → node 104.IP aspect, this transmission path is node 101 → node 102 → node 104, as shown in the solid black lines arrow in Fig. 1.

When the node 105 of photosphere and the link occurs fault between node 107, as the star representation node 105 in Fig. 1 and the fiber cut failure between node 107.Now, node 105 and node 107 can be found the loss of light signal, just carry out the protection switching operation of photosphere.For example, the light path between node 105 and node 107 is switched to node 105 → node 106 → node 107.Now, the node 101 of IP layer to the actual transmission paths of node 104 becomes: node 101 → node 102 → node 105 → node 106 → node 107 → node 104.But IP aspect, this transmission path is still node 101 → node 102 → node 104.

On the other hand, the mechanism that has similar heartbeat detection between the node of IP layer maintains the connection between node.When the time that heartbeat between node 102 and node 104 is interrupted surpasses the holdoff timer that it sets in advance, just think that fault has appearred in the link between node 102 and node 104, now IP layer just starts quick heavy-route (Fast Route Restoration, FRR).For example, node 101 can be switched to node 101 → node 103 → node 104 to the transmission path of node 104, and this is the transmission path IP aspect, as shown in the black dotted lines arrow in Fig. 1.And now node 101 to the actual transmission paths of node 104 becomes: node 101 → node 103 → node 106 → node 107 → node 104.

Actual, while breaking down, first by photosphere, carry out protection switching operation in IP-over-Optical network, if in the holdoff of IP layer timer, photosphere does not complete protection switching operation, just start FRR by IP layer.

Because IP layer photoreactive layer is separate, it is enough large that IP layer can only arrange holdoff timer, and guarantee photosphere is carried out the time of protection switching operation.But holdoff timer overlong time, can cause the overlong time of service disconnection.And, by the protection switching operation of photosphere, or the transmission path that redefines of the FRR by the IP layer optimal transmission paths in IP-over-Optical network not necessarily, the wasting of resources may be caused.
