103rd, for each business, IP layers corresponding to the photosphere control network element request control network element from it is described at least It is that the business is determined for one the 3rd UNI links instead of the first UNI links in one the 2nd UNI links.
Wherein, it is the control network element in IP network that the IP layers, which control network element, can be to the node in IP network, i.e. IP layers The IP layer operating paths of node, and the operating path of business in an ip network, i.e. business are managed and controlled.
For example, for business A, IP layers corresponding to the photosphere control network element request control network element corresponding from business A The 2nd UNI links 1,2 in for business A determine for replace the first UNI links one the 3rd UNI links, for business B, it is business that IP layers corresponding to the photosphere control network element request, which are controlled in the 2nd UNI links 3,4,5 corresponding to network element from business A, B determines one the 3rd UNI links for replacing the first UNI links.
Specifically, there is at least one photosphere control network element in optical-fiber network, there is at least one IP layers control network element in IP network. Alternatively, each photosphere control network element has a corresponding IP layers control network element.
Alternatively, IP layers corresponding to the photosphere control network element request control network element from least one the 2nd UNI links In be the business determine for replace the first UNI links one the 3rd UNI links, including:
The photosphere controls network element to send collaboration recovery request, the collaboration recovery request bag to IP layers control network element Include:Information, the information of the business of the information of the first UNI links, at least one the 2nd UNI links, the collaboration Recovery request is used to ask from least one the 2nd UNI links to be that the business determines to be used to replace the first UNI chains One the 3rd UNI links on road.
Alternatively, the information of the first UNI links includes:The information of the first photosphere node, and/or, described The information of one IP node layers.
Alternatively, the information of the business includes the service identification of the business.

The information of above-mentioned photosphere node or IP node layers alternatively includes the node identification of the node.
In a kind of possible scene, at least one the 2nd UNI links include multiple 2nd UNI links.In this scene In, alternatively, methods described also includes:
Determine the photosphere adjacency of the multiple 2nd UNI links and the first UNI links;
The collaboration recovery request also includes:The photosphere of the multiple 2nd UNI links and the first UNI links is neighbouring Degree.
Generally, when the twoth UNI link higher with the photosphere adjacency of the first UNI links is defined as into the 3rd UNI During link, former photosphere operating path can be retained to large extent.Correspondingly, the photosphere adjacency can indicate the IP layers Control the priority of the multiple 2nd UNI links of network element.Alternatively, the 2nd higher UNI links of photosphere adjacency is preferential Level is higher.Correspondingly, the IP layers control network element can be according to the multiple 2nd UNI links and the first UNI links The order of photosphere adjacency from high to low carries out calculation road successively, if calculating road success, the successful 2nd UNI link conducts in Ze Jiangsuan roads The 3rd UNI links, and stop carrying out calculation road according to the 2nd follow-up UNI links.
Alternatively, the photosphere adjacency of the multiple 2nd UNI links and the first UNI links, respectively with it is each described Hop count between second photosphere node of the 2nd UNI link connections and the first photosphere node of the first UNI link connections has Close.Specifically, hop count is fewer, and photosphere adjacency is higher.
For example, as shown in Figure 1 b, it is assumed that the UNI link failures between O-N3 and IP-N4, i.e. O-N3 are the first photosphere Node, then photosphere control network element determine on the former photosphere operating path and have at least one second photosphere of UNI links Node has:O-N4, O-N8, O-N12, wherein, hop count of the hop count between 1, O-N8 and O-N3 between O-N4 and O-N3 is 2, Hop count between O-N12 and O-N3 is 4;If the 2nd UNI links between O-N4 and IP-N14 are defined as into the 3rd UNI links, The path that O-N4, O-N8, O-N9, O-N12 in former photosphere operating path are formed can then be retained, if by O-N8 and IP-N12 it Between the 2nd UNI links be defined as the 3rd UNI links, then can retain O-N8, O-N9, O-N12 in former photosphere operating path The path of composition, the like, it is known that, determined when by the corresponding 2nd UNI links of the minimum O-N4 of the hop count between O-N3 For the 3rd UNI links when, former photosphere operating path can be retained to large extent.
In adjacent node is also served as into the implementation of the node relevant with former photosphere operating path, alternatively, also Can with according to whether distinguished on former operating path the 2nd UNI links corresponding to the second photosphere node of same number of hops with it is described The photosphere adjacency of first UNI links.Alternatively, in hop count under the same conditions, second corresponding to the node on operating path The photosphere adjacency of UNI links and the first UNI links the 2nd UNI links corresponding higher than adjacent node and described first The photosphere adjacency of UNI links, or, the 2nd UNI links corresponding to the node on operating path and the first UNI links Photosphere adjacency of the photosphere adjacency less than the 2nd UNI links corresponding to adjacent node and the first UNI links.
For example, as shown in Figure 1 b, it is assumed that the UNI link failures between O-N3 and IP-N4, worked with the former photosphere The path-dependent and at least one second photosphere node for having UNI links has:O-N4, O-N8, O-N12, O-N5, O-N7, wherein, O- N4, O-N8, O-N12 are the node on former photosphere operating path, and O-N5, O-N7 are adjacent with the node on former photosphere operating path Node.Hop count between O-N4 and O-N3 is 1, and the hop count between O-N5, O-N8 and O-N3 is between 2, O-N7 and O-N3 Hop count of the hop count between 3, O-N12 and O-N3 be 4;If the 2nd UNI links corresponding to the node on operating path with it is described Photosphere of the photosphere adjacency of first UNI links higher than the 2nd UNI links corresponding to adjacent node and the first UNI links The relation of adjacency, then the photosphere adjacency of the 2nd UNI links corresponding to above-mentioned second photosphere node and the first UNI links For:O-N4>O-N8>O-N5>O-N7>The photosphere of 2nd UNI links corresponding to O-N12, i.e. O-N4 and the first UNI links is adjacent Recency highest, the 2nd UNI links corresponding to O-N8 are higher than O-N5 corresponding second with the photosphere adjacency of the first UNI links The photosphere adjacency of UNI links and the first UNI links, the like;If the 2nd UNI corresponding to the node on operating path Link is with the photosphere adjacency of the first UNI links less than the adjacent corresponding 2nd UNI links of node and the first UNI The photosphere adjacency of link, then the photosphere of the 2nd UNI links corresponding to above-mentioned second photosphere node and the first UNI links is adjacent The relation of recency is:O-N4>O-N5>O-N8>O-N7>2nd UNI links corresponding to O-N12, i.e. O-N4 and the first UNI chains The photosphere adjacency highest on road, the photosphere adjacency of the 2nd UNI links corresponding to O-N5 and the first UNI links are higher than O-N8 The photosphere adjacency of corresponding 2nd UNI links and the first UNI links, the like.
In any of the above-described optional implementation, alternatively, as illustrated in figure 1 c, the present embodiment also includes:
104th, photosphere control network element receives the calculation road successful information that the IP floor control network element is sent, the calculation road into Work(information includes the information of the 3rd UNI links.
Wherein, the information of the 3rd UNI links includes:One the 3rd photosphere node of described 3rd UNI links one end Information, and/or, the information of one the 3rd IP node layers of the other end.The information of above-mentioned photosphere node or IP node layers is alternatively wrapped Include the node identification of the node.
Generally, one at least one the 2nd UNI links during the 3rd UNI links are 103.
Specifically, IP layers control network element can be to described in the first IP node layers, 103 at least one second 2nd IP node layers corresponding to any of UNI links carry out calculation road, and successful one the 2nd UNI links in Bing Jiangsuan roads are defined as institute The 3rd UNI links are stated, detailed process can refer to fault handling method embodiment two provided by the invention.
105th, the photosphere controls network element to determine the new photosphere work of the business according to the information of the 3rd UNI links Make path.
Alternatively, photosphere control network element one the 3rd photosphere node according to corresponding to the 3rd UNI links, it is determined that The new photosphere operating path of the business, the 3rd photosphere node is on the new photosphere operating path.
Generally, the former operating path of a business includes:Former IP layers operating path, former photosphere operating path, and connection are former At least two UNI links of IP layers operating path and former photosphere operating path.As shown in Figure 1 b, two in former operating path UNI links are:IP-N4 → O-N3, O-N12 → IP-N9, wherein, IP-N4 → O-N3 is the first UNI links to break down.It is false If the 3rd UNI links that the IP layers control network element to determine are IP-N14 → O-N4, i.e., corresponding to described 3rd UNI links One the 3rd photosphere node is O-N4, then the photosphere control network element can determine that the new photosphere operating path of the business includes: O-N4→O-N8→O-N9→O-N12;Assuming that the 3rd UNI links that the IP layers control network element to determine are IP-N6 → O- N5, i.e., one the 3rd photosphere node corresponding to described 3rd UNI links is O-N5, then described in photosphere control network element can determine The new photosphere operating path of business includes:O-N5→O-N4→O-N8→O-N9→O-N12.
Alternatively, 105 also include afterwards:The photosphere controls network element to send collaboration recovery to IP layers control network element and opened Dynamic information, the collaboration recover to start information for notifying that photosphere control network element has determined that described described in the IP layers control network element The new photosphere operating path of business.
Specifically, IP layers control network element can be it is determined that after the new IP layers operating path of the business, described new It is new IP layer operating paths described in the business configuration on each IP node layers on IP layer operating paths, if the and the described 3rd The direction of the business is from IP layer to photosphere on UNI links, then the IP layers control network element can also be in the 3rd IP layers It is the 3rd UNI links described in the business configuration on node;Similarly, the photosphere control network element can be it is determined that the business New photosphere operating path after, be new light described in the business configuration on each photosphere node on the new photosphere operating path Layer operating path, and if the direction of the business is the photosphere control from photosphere to IP layers on the 3rd UNI links Network element can also be the 3rd UNI links described in the business configuration on the 3rd photosphere node.Alternatively, if the business New photosphere operating path be not completely contained in the former photosphere operating path of the business, such as, new photosphere operating path is O-N5 → O-N4 → O-N8 → O-N9 → O-N12, former photosphere operating path are O-N3 → O-N4 → O-N8 → O-N9 → O-N12, And the 3rd UNI links are:IP-N6 → O-N5, then the photosphere control network element only need to be in the new light included in the business In layer operating path but the photosphere node that is not included in the former photosphere operating path of the business, as being the business on O-N5 Configure the new photosphere operating path;If the new photosphere operating path of the business is completely contained in the former photosphere work of the business Make in path, such as, new photosphere operating path is O-N4 → O-N8 → O-N9 → O-N12, former photosphere operating path be O-N3 → O-N4 → O-N8 → O-N9 → O-N12, if the 3rd UNI links are:O-N4 → IP-N14, then photosphere control network element is only It is the 3rd UNI links described in the business configuration on O-N4 that need to be in the 3rd photosphere node, if the 3rd UNI links For:IP-N14 → O-N4, then the photosphere control network element need not carry out any configuration, because each light on new photosphere operating path Configuration needed for node layer is identical with its required configuration on former photosphere operating path.
The configuration of each IP node layers, each photosphere node is completed on above-mentioned new operating path, it is believed that fault recovery is completed. After fault recovery is completed, if receiving the packet of the business, each IP node layers on the new IP layers operating path are equal The packet, the new photosphere operating path are forwarded according to the UNI links in the new IP layers operating path or new operating path On each photosphere node forward the packet according to the UNI links in the new photosphere operating path or new operating path.

Generally, when the twoth UNI link higher with the photosphere adjacency of the first UNI links is defined as into the 3rd UNI During link, former photosphere operating path can be retained to large extent.Correspondingly, the photosphere adjacency can indicate the IP layers Control the priority of the multiple 2nd UNI links of network element.Alternatively, the 2nd higher UNI links of photosphere adjacency is preferential Level is higher.Correspondingly, the IP layers control network element can be according to the multiple 2nd UNI links and the first UNI links The order of photosphere adjacency from high to low carries out calculation road successively, if calculating road success, the successful 2nd UNI link conducts in Ze Jiangsuan roads The 3rd UNI links, and stop carrying out calculation road according to the 2nd follow-up UNI links.
Alternatively, the photosphere adjacency of the multiple 2nd UNI links and the first UNI links, respectively with it is each described Hop count between second photosphere node of the 2nd UNI link connections and the first photosphere node of the first UNI link connections has Close.Specifically, hop count is fewer, and photosphere adjacency is higher.
Alternatively, as shown in Figure 2 b, the present embodiment also includes:
203rd, the IP floor controls network element to be sent to photosphere control network element and calculates road successful information, and the calculation road is successfully believed Breath includes the information of the 3rd UNI links, and the calculation road successful information is used to indicate that the photosphere controls network element according to The information of 3rd UNI links determines the new photosphere operating path of the business.
Specifically, the photosphere control network element can determine industry according to fault handling method embodiment one provided by the invention The new photosphere operating path of business.Alternatively, one second photosphere node position corresponding to calculation successful one the 2nd IP node layers in road In on the new photosphere operating path of the business.
For example, as shown in Figure 1 b, it is assumed that the first UNI links to break down are IP-N4 → O-N3, i.e. the first IP Node layer is IP-N4, and the direction of the business is from IP layer to photosphere on the first UNI links, and the photosphere control network element can With the second photosphere corresponding at least one the 2nd UNI links described in being determined according to fault handling method embodiment one provided by the invention Node has:O-N4, O-N8, O-N5, O-N7, O-N12, correspondingly, the 2nd IP layer sections at least corresponding to one the 2nd UNI links Point has:IP-N14, IP-N12, IP-N6, IP-N10, IP-N9, and above-mentioned second photosphere node and the 2nd IP node layers are pressed Arranged according to the order of the photosphere adjacency of affiliated 2nd UNI links and the first UNI links from high to low, the IP layers control Network element can calculate the upstream IP node layers from IP-N4 successively, i.e. IP-N1 works as calculating to the path of above-mentioned 2nd IP node layers During path from IP-N1 to IP-N14, according to the network topology of IP layers as shown in Figure 1 b, it may be determined that from IP-N1 to IP- N14 path is:IP-N1 → IP-N2 → IP-N5 → IP-N14, Ji Suan road success, alternatively terminate calculate road, by IP-N14 → O-N4 determines that the new IP layers operating path of the business includes as the 3rd UNI links:IP-N1→IP-N2→IP- N5 → IP-N14, alternatively, the photosphere control network element can determine the new photosphere of the business according to the 3rd UNI links Operating path includes:O-N4→O-N8→O-N9→O-N12.
Again for example, as shown in Figure 1 b, it is assumed that the first UNI links to break down are O-N12 → IP-N9, i.e. first IP node layers are IP-N9, and the direction of the business is from photosphere to IP layers on the first UNI links, and the photosphere controls network element Can the second light corresponding at least one the 2nd UNI links according to determining fault handling method embodiment one provided by the invention Node layer has:O-N8, O-N7, O-N4, O-N5, O-N3, correspondingly, the 2nd IP layers at least corresponding to one the 2nd UNI links Node has:IP-N12, IP-N10, IP-N14, IP-N6, IP-N4, and above-mentioned second photosphere node and the 2nd IP node layers are equal Arranged according to the order of the photosphere adjacency of affiliated 2nd UNI links and the first UNI links from high to low, the IP layers control Network element processed can calculate from above-mentioned 2nd IP node layers to IP-N9 path successively, when path of the calculating from IP-N12 to IP-N9 When, road failure is calculated, then calculates the path from IP-N10 to IP-N9, it may be determined that the path from IP-N10 to IP-N9 is:IP- The success of N10 → IP-N11 → IP-N9, Ji Suan road, alternatively terminate to calculate road, using O-N7 → IP-N10 as the 3rd UNI chains Road, and determine that the new IP layers operating path of the business includes:IP-N1 → IP-N4, IP-N10 → IP-N11 → IP-N9, it is optional Ground, the photosphere control network element can determine that the new photosphere operating path of the business according to the 3rd UNI links includes:O- N3→O-N4→O-N8→O-N7。
Alternatively, 203 also include afterwards:It is extensive that the IP layers control network element receives the collaboration that the photosphere control network element is sent Start information again, the collaboration recovers to start information for notifying that photosphere control network element has determined that described in the IP layers control network element The new photosphere operating path of the business.
Specifically, IP layers control network element can it is determined that after the new IP layers operating path of the business, i.e., 202 it Afterwards, on each IP node layers on the new IP layers operating path it is new IP layer operating paths described in the business configuration, and If the direction of the business is from IP layer to photosphere on the 3rd UNI links, the IP layers control network element can also be in institute State on the 3rd IP node layers is the 3rd UNI links described in the business configuration;Similarly, the photosphere control network element can be true It is that the business is matched somebody with somebody on each photosphere node on the new photosphere operating path after the new photosphere operating path of the fixed business The new photosphere operating path is put, and if the direction of the business is the institute from photosphere to IP layers on the 3rd UNI links It can also be the 3rd UNI links described in the business configuration on the 3rd photosphere node to state photosphere control network element.Alternatively, If the new photosphere operating path of the business is not completely contained in the former photosphere operating path of the business, such as, new photosphere Operating path is O-N5 → O-N4 → O-N8 → O-N9 → O-N12, and former photosphere operating path is O-N3 → O-N4 → O-N8 → O- N9 → O-N12, and the 3rd UNI links are:IP-N6 → O-N5, then the photosphere control network element only need to be included in described In the new photosphere operating path of business but the photosphere node that is not included in the former photosphere operating path of the business, on O-N5 For new photosphere operating path described in the business configuration;If the new photosphere operating path of the business is completely contained in the business Former photosphere operating path in, such as, new photosphere operating path is O-N4 → O-N8 → O-N9 → O-N12, former photosphere working ways Footpath is O-N3 → O-N4 → O-N8 → O-N9 → O-N12, if the 3rd UNI links are:O-N4 → IP-N14, the then photosphere It is the 3rd UNI links described in the business configuration on O-N4 that control network element only need to be in the 3rd photosphere node, if described the Three UNI links are:IP-N14 → O-N4, then the photosphere control network element need not carry out any configuration, because new photosphere working ways Configuration needed for each photosphere node on footpath is identical with its required configuration on former photosphere operating path.
The configuration of each IP node layers, each photosphere node is completed on above-mentioned new operating path, it is believed that fault recovery is completed. After fault recovery is completed, if receiving the packet of the business, each IP node layers on the new IP layers operating path are equal The packet, the new photosphere operating path are forwarded according to the UNI links in the new IP layers operating path or new operating path On each photosphere node forward the packet according to the UNI links in the new photosphere operating path or new operating path.
In a kind of optional implementation, the IP layers control network element opens when receiving the collaboration recovery request A dynamic timer, the expired time of the timer is acceptable failure recovery time, if during the timer expiration, the IP layers Control network element does not determine the 3rd UNI links yet, such as, each Ci Suan roads performed fail, then the IP layers control Network element processed stops calculating road, is returned to photosphere control network element and calculates road failure information.
A kind of possible scene is, before the timer expiration, the IP floor control network element calculates road success, that is, determines institute The 3rd UNI links are stated, correspondingly, the IP layers control network element closes the timer.
Another possible scene is, before the timer expiration, the IP layers control network element is directed to the collaboration All 2nd UNI links in recovery request carry out calculation road, and the failure of Qie Junsuan roads, now, the IP layers control network element can also Calculation road failure information is returned to photosphere control network element and closes the timer.
Correspondingly, the photosphere control network element can stop fault recovery according to the calculation road failure information.
The present embodiment controls network element to control network element Coordination to carry out troubleshooting with corresponding photosphere by IP layers, A kind of processing scheme for being directed to link failure between photosphere and IP layers in optical network bearing IP network is provided, further can be with Take into full account, former operating path of the retained business in optical-fiber network, accelerate the response speed of fault recovery, to shorten failure extensive Multiple switching time, realize the fault recovery of highly reliable, high efficiency, low cost.

Generally, an at least business described in the first UNI links carrying refers to, the packet of an at least business can be through The first UNI links are crossed, in other words, the first UNI links are included in the former operating path of an at least business.
In a kind of optional implementation, the first determining module 31 is specifically used for:Receive the first photosphere node hair The fault message sent, the fault message include the service identification of an at least business.
Specifically, the photosphere node of UNI both link ends and IP node layers can perceive the failure of the UNI links.Generally, Compared to IP node layers, photosphere node can quickly perceive the failure of UNI links, so as to respond earlier, as above Report fault message.
Generally, the new operating path of the business includes:New IP layers operating path, the new light of the business of the business Layer operating path, and connect at least the two of the new IP layers operating path of the business and the new photosphere operating path of the business Bar UNI links;The former operating path of the business is also similar.
For operating path of the retained business in photosphere as much as possible, i.e. the new photosphere operating path of business to the greatest extent may be used Energy ground overlaps with the former photosphere operating path of the business, to shorten the recovery time of failure, alternatively, described at least one second UNI links are relevant with the former photosphere operating path of the business.
For example, the business of the first UNI links carrying has business A and business B, and mould is determined for business A, first Block 31 determines that the 2nd UNI links 1,2 of the first UNI links can be replaced in business A new operating path, for business B, the first determining module 31 determine that the 2nd UNI links of the first UNI links can be replaced in business B new operating path 3、4、5;Alternatively, the 2nd UNI links 1,2 are relevant with business A former photosphere operating path, the 2nd UNI links 3,4,5 with Business B former photosphere operating path is relevant.
Specifically, every one second UNI links can by the photosphere node of the 2nd UNI links one end, and/or, it is another The IP node layers at end, to identify/determine.
Alternatively, the second determining module 32 is specifically used for:It is determined that relevant with the former photosphere operating path and have UNI links At least one second photosphere node.
That is, the second determining module 32 will be relevant with the former photosphere operating path of the business and have UNI links An at least UNI links corresponding to an at least photosphere node are defined as that described the can be replaced in the new operating path of the business The UNI links of one UNI links.
Specifically, the photosphere node for having UNI links refers to that the photosphere node is connected with UNI links and the UNI links are in Normal operating conditions, wherein, the first UNI links of failure can consider in abnormal operating state.
Alternatively, the second determining module 32 is specifically additionally operable to:It is determined that pass through UNI links and at least one second photosphere section At least one the 2nd IP node layers of point connection.
For example, as shown in Figure 1 b, there is photosphere node O-N1~O-N12 in optical-fiber network, there are IP node layers in IP network IP-N1~IP-N14, it is assumed that the UNI link failures between O-N3 and IP-N4, then the second determining module 32 determine photosphere node O- N2, O-N4, O-N5, O-N7, O-N8, O-N12 have UNI links, photosphere node O-N1, O-N3, O-N6, O-N9, O-N10, O-N11 Without UNI links.Second determining module 32 is determined by UNI links and photosphere node O-N2, O-N4, O-N5, O-N7, O-N8, O- The IP node layers of N12 connections are respectively:IP-N3、IP-N14、IP-N6、IP-N10、IP-N12、IP-N9.
In a kind of optional implementation, the second determining module 32 is specifically used for:It is determined that in the former photosphere working ways On footpath and there is an at least one second photosphere node of UNI links.
For example, as shown in Figure 1 b, the former operating path of a business includes:IP-N1→IP-N4→O-N3→O-N4→ O-N8 → O-N9 → O-N12 → IP-N9, wherein, the former photosphere operating path of the business includes:O-N3→O-N4→O-N8→O- N9 → O-N12, i.e. the photosphere node on former photosphere operating path has:O-N3, O-N4, O-N8, O-N9, O-N12, it is assumed that The first UNI links to break down are IP-N4 → O-N3, then the second determining module 32 determines have with the former photosphere operating path At least one second photosphere node for closing and having UNI links has:O-N4、O-N8、O-N12.
In another optional implementation, the second determining module 32 is specifically used for:It is determined that worked in the former photosphere On path and there is an at least one second photosphere node of UNI links;It is determined that with it is any adjacent at least one second photosphere node And there is at least one second photosphere node again of UNI links.
Alternatively, the adjacent hop count referred between node is 1.For example, as shown in Figure 1 b, the former working ways of a business Footpath includes:IP-N1 → IP-N4 → O-N3 → O-N4 → O-N8 → O-N9 → O-N12 → IP-N9, wherein, the former photosphere of the business Operating path includes:O-N3 → O-N4 → O-N8 → O-N9 → O-N12, then the second determining module 32 determine in the former photosphere work At least one second photosphere node made on path and have UNI links has:O-N4, O-N8, O-N12, further, second determines mould Block 32 determines have with least one second photosphere node again that is any adjacent in O-N4, O-N8, O-N12 and having UNI links:O-N5、 O-N7, i.e. the second determining module 32 determines at least one second photosphere relevant with the former photosphere operating path and having UNI links Node has:O-N4、O-N8、O-N12、O-N5、O-N7.
Wherein, the request object of request module 33 --- the IP layers control network element, are the control network element in IP network, can With the IP layer operating paths to the node in IP network, i.e. IP node layers, and the operating path of business in an ip network, i.e. business It is managed and controls.
For example, for business A, request module 33 ask IP layers corresponding to photosphere control network element 300 control network element from One the 3rd UNI links for replacing the first UNI links are determined for business A in 2nd UNI links 1,2 corresponding to business A, For business B, request module 33 asks the 2nd UNI corresponding to IP layers control network element from business A corresponding to photosphere control network element 300 In link 3,4,5 one the 3rd UNI links for replacing the first UNI links are determined for business B.
Specifically, there is at least one photosphere control network element 300 in optical-fiber network, there is at least one IP layers control net in IP network Member.Alternatively, each photosphere control network element 300 has a corresponding IP layers control network element.
Alternatively, request module 33 is specifically used for:Collaboration recovery request, the collaboration are sent to IP layers control network element Recovery request includes:The information of the first UNI links, at least information of one the 2nd UNI links, the letter of the business Breath, the collaboration recovery request are used to ask from least one the 2nd UNI links to be that the business determines to be used to replace institute State one the 3rd UNI links of the first UNI links.
Alternatively, the information of the first UNI links includes:The information of the first photosphere node, and/or, described The information of one IP node layers.
Alternatively, the information of the business includes the service identification of the business.
Alternatively, the information of at least one the 2nd UNI links includes:The information of at least one second photosphere node, And/or the information of at least one the 2nd IP node layers.
The information of above-mentioned photosphere node or IP node layers alternatively includes the node identification of the node.
In a kind of possible scene, at least one the 2nd UNI links include multiple 2nd UNI links.In this scene In, alternatively, as shown in Figure 3 b, photosphere control network element 300 also includes:3rd determining module 34, for determining the multiple The photosphere adjacency of two UNI links and the first UNI links;
The collaboration recovery request also includes:The photosphere of the multiple 2nd UNI links and the first UNI links is neighbouring Degree.
Generally, when the twoth UNI link higher with the photosphere adjacency of the first UNI links is defined as into the 3rd UNI During link, former photosphere operating path can be retained to large extent.Correspondingly, the photosphere adjacency can indicate the IP layers Control the priority of the multiple 2nd UNI links of network element.Alternatively, the 2nd higher UNI links of photosphere adjacency is preferential Level is higher.Correspondingly, the IP layers control network element can be according to the multiple 2nd UNI links and the first UNI links The order of photosphere adjacency from high to low carries out calculation road successively, if calculating road success, the successful 2nd UNI link conducts in Ze Jiangsuan roads The 3rd UNI links, and stop carrying out calculation road according to the 2nd follow-up UNI links.
Alternatively, the photosphere adjacency of the multiple 2nd UNI links and the first UNI links, respectively with it is each described Hop count between second photosphere node of the 2nd UNI link connections and the first photosphere node of the first UNI link connections has Close.Specifically, hop count is fewer, and photosphere adjacency is higher.
For example, as shown in Figure 1 b, it is assumed that the UNI link failures between O-N3 and IP-N4, i.e. O-N3 are the first photosphere Node, then the second determining module 32 determine on the former photosphere operating path and have at least one second photosphere section of UNI links Point has:O-N4, O-N8, O-N12, wherein, hop count of the hop count between 1, O-N8 and O-N3 between O-N4 and O-N3 is 2, O- Hop count between N12 and O-N3 is 4;If the IP layers control network element determines the 2nd UNI links between O-N4 and IP-N14 For the 3rd UNI links, then photosphere control network element 300 can retain O-N4, O-N8, O-N9, O-N12 in former photosphere operating path The path of composition, if the 2nd UNI links between O-N8 and IP-N12 are defined as the 3rd UNI chains by IP layers control network element Road, then photosphere control network element 300 can retain the path that O-N8, O-N9, O-N12 in former photosphere operating path are formed, successively Analogize, it is known that, when IP layers control network element determines the corresponding 2nd UNI links of the minimum O-N4 of the hop count between O-N3 For the 3rd UNI links when, photosphere control network element 300 can retain former photosphere operating path to large extent.
In adjacent node is also served as into the implementation of the node relevant with former photosphere operating path, alternatively, the Three determining modules 34 can be with according to whether distinguish corresponding to the second photosphere node of same number of hops on former operating path The photosphere adjacency of two UNI links and the first UNI links.Alternatively, in hop count under the same conditions, on operating path The photosphere adjacency of 2nd UNI links corresponding to node and the first UNI links twoth UNI corresponding higher than adjacent node The photosphere adjacency of link and the first UNI links, or, the 2nd UNI links and institute corresponding to the node on operating path State light of the photosphere adjacency less than the 2nd UNI links corresponding to adjacent node and the first UNI links of the first UNI links Layer adjacency.
