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 only 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.

The embodiment of the present invention provides the method for the data retransmission in a kind of group system, as shown in Figure 1, comprising:

101, the controller in group system obtains signaling by the first fringe node in described group system.

Wherein, described signaling is used to indicate described group system and sets up the first path, described the first path is the path of the second fringe node from described the first fringe node to described group system, the required bandwidth of information and described the first path of carrying described the second fringe node in described signaling.

It should be noted that, group system comprises in embodiments of the present invention: controller, at least one forward node.

It should be noted that, in group system can with group system outside external node carry out mutual forward node and be called fringe node.For external node, the annexation between fringe node can be by the TE(Traffic Engineer between fringe node, traffic engineering) link represents.These TE Links can be the direct physical connections between the node of two edges, can be also that the logic between the node of two edges connects, and are two edges node and couple together step by step by the physical connection between non-fringe node in group system.

It should be noted that, group system can only receive the Business Stream that external node sends by fringe node.

It should be noted that, in embodiments of the present invention, the TE ability between group system fringe node can appear as the maximum bandwidth capability that can support between the node of two edges.Wherein, maximum bandwidth capability refers in group system the bandwidth value of the bandwidth summation of all transmission paths between the node of two edges.

It should be noted that, described the second fringe node is node different from described the first fringe node in described group system.Described the second fringe node is the node that described business will send to.

It should be noted that, the information of described the second fringe node can comprise the information such as described the second address of node, edge, port.

Further, described signaling comprises RSVP RSVP(ReSource reserVation Protocol, RSVP).

Further, be to carry out at controller, or carry out at the first fringe node according to the parsing of signaling, the required bandwidth of information and described the first path that described controller obtains the second fringe node can be divided into two kinds of situations.

The first situation, when the parsing of signaling is while carrying out on controller, described the first fringe node receives after the signaling that the external node of group system sends, and after the format conversion of this signaling is the form that can identify of controller, the signaling after format transformation is sent to controller.Controller receives after signaling, then signaling is resolved, and obtains the required bandwidth of information and described the first path of carrying described the second fringe node in signaling.

The second situation, when the parsing of signaling is while carrying out on the first fringe node, described the first fringe node receives after the signaling that the external node of group system sends, the first fringe node is resolved this signaling, and obtain the required bandwidth of information and described the first path of carrying described the second fringe node in signaling, finally the required bandwidth of the information of the second fringe node getting and the first path is sent to controller.

102, controller, according to described signaling, is determined at least two transmission paths in described group system.

Wherein, described at least two transmission paths bandwidth summations are not less than the required bandwidth in described the first path.

Concrete, controller is according to the required bandwidth in the first path of carrying in signaling, in the mode of maximum bandwidth optimal path, according to the first algorithm, determines at least two transmission paths between the first fringe node and the second fringe node in described group system.

It should be noted that, the mode of described maximum bandwidth optimal path is exactly the mode in path of determining according to bandwidth, and the path that is about to bandwidth maximum is defined as the mode of optimal path.

It should be noted that, described the first algorithm can be CSPF(constrained shorest path first, restricted shortest path footpath algorithm), or the off-line algorithm of increasing income, or the algorithm of increasing income online, or other algorithms, the present invention is not restricted this.

Further, controller determines that the method for at least two transmission paths can be divided into two kinds.First method is at least two transmission paths described in controller is determined one by one; Second method is at least two transmission paths described in controller is once determined.

Concrete, first method comprises: described controller, according to described signaling, is determined the first transmission path in described group system; Whether the bandwidth that detects described the first transmission path meets the required bandwidth in described the first path; If the bandwidth of described the first transmission path does not meet the required bandwidth in described the first path, according to described signaling, determine at least one the second transmission paths; Whether the bandwidth summation that detects described the first transmission path and described at least one the second transmission paths meets the required bandwidth in described the first path; If the bandwidth summation of described the first transmission path and described at least one the second transmission paths meets the required bandwidth in described the first path, at least two transmission paths described in described the first transmission path and described at least one the second transmission paths being defined as.If the bandwidth summation of described the first transmission path and described at least one the second transmission paths does not meet the required bandwidth in described the first path, continue according to described signaling, determine described at least one the second transmission paths, until the bandwidth summation of all transmission paths of determining meets the required bandwidth in described the first path, at least two transmission paths described in described all transmission paths of determining are defined as.

It should be noted that, described the first transmission path just refers to the internodal article one transmission path of described the first fringe node and the second edge that described controller is determined.

It should be noted that, the required bandwidth value in the bandwidth value that controller can provide the first transmission path of determining and the first path compares, thereby determines whether the bandwidth of described the first transmission path meets the required bandwidth in described the first path.

It should be noted that, if the bandwidth of described the first transmission path meets the required bandwidth in the first path, the bandwidth value that the first transmission path of determining can provide is not less than the required bandwidth in the first path, identical with situation about just can transmit Business Stream by a paths in prior art, the present invention no longer illustrates at this.

Need to say, described the second transmission path is between the first fringe node and the second fringe node, the path different from described the first transmission path.Any two transmission paths in described at least one the second transmission paths are different.

It should be noted that, controller can the required bandwidth value of the value of the maximum bandwidth sum that can provide between at least one the second transmission paths of having determined and the first transmission path and the first path be provided, and determines whether the bandwidth summation of the first transmission path and at least one the second transmission paths meets the required bandwidth in the first path.

Exemplary, shown in figure 2, group system comprises: controller, forward node B, C, D, E.Wherein, forward node B and E are fringe node, and Node B is the first fringe node, and node E is the second fringe node, and the required bandwidth in the first path is 50G.

Concrete, the bandwidth that controller is required according to the first path, the mode of passing through maximum bandwidth optimal path between Node B and node E is according to the first algorithm, calculate the first transmission path: Node B → node D → node E, and the bandwidth of obtaining the first transmission path and can providing is 30G, controller, by detecting, show that the bandwidth 30G that can provide of the first transmission path does not meet the required bandwidth 50G in first via footpath.Now, controller is according to the bandwidth that can provide of the required bandwidth in the first path and the first transmission path, continues to determine at least one the second transmission paths between Node B and node E.Controller passes through the mode of maximum bandwidth optimal path according to the first algorithm, calculate second transmission path: Node B → node C → node E, and the bandwidth that the transmission path between Node B → node C → node E can provide is 20G, controller detect the first transmission path and second transmission path having determined between bandwidth summation whether meet the required bandwidth in the first path.Be, whether the bandwidth summation 50G of the transmission path between the transmission path between controller detection node B → node D → node E and Node B → node C → node E meets the required bandwidth 50G in the first path.The bandwidth summation 50G that controller detects transmission path between Node B → node D → node E and the transmission path between Node B → node C → node E meets the required bandwidth 50G in the first path, the transmission path between the transmission path between Node B → node D → node E and Node B → node C → node E is defined as at least two transmission paths.

Second method comprises: controller, according to described signaling, is once determined at least two transmission paths between the first fringe node and the second fringe node.

Concrete, the bandwidth that controller can be required according to the first path is passed through the mode of maximum bandwidth optimal path according to the first algorithm between Node B and node E, once calculates two transmission paths.Article one, transmission path is the transmission path between Node B → node D → node E, second transmission path is the transmission path between Node B → node C → node E, now, the bandwidth that transmission path between Node B → node D → node E can provide is 30G, and the bandwidth that the transmission path between Node B → node C → node E can provide is 20G.The bandwidth summation of two transmission paths of once determining necessarily meets the required bandwidth 50G in the first path.Controller is defined as at least two transmission paths by the transmission path between the transmission path between Node B → node D → node E and Node B → node C → node E.

103, controller sends configuration information to described the first fringe node.

Wherein, configuration information and the indication information of at least two transmission paths described in described configuration information comprises, described indication information is used to indicate described the first fringe node and to described at least two transmission paths, forwards described Business Stream after receiving Business Stream.

For instance, in the configuration information of described at least two transmission paths, record a upper forward node address information of each forward node in transmission path and the address information of its next forward node.

For instance, controller not only will send described configuration information to described the first fringe node, but also all nodes that will comprise to described at least two transmission paths send described configuration information, so that all forward node in transmission path, according to the configuration information of described transmission path, can be forwarded to the signaling receiving next forward node in the path of determining.

Further, described indication information is specifically for indicating described the first fringe node after receiving Business Stream, and the mode by described Business Stream with non-equivalence load balancing, described in being sent at least two transmission paths.

It should be noted that, described non-equivalence load balancing is a kind of forwarding data flow strategy, when data flow is transmitted on many transmission paths, the ratio of the bandwidth that can provide according to every transmission paths, in proportion data stream is transmitted, according to the bandwidth that in described at least two transmission paths, each transmission paths can provide, described Business Stream is transmitted respectively with different pro rates to described at least two transmission paths.

It should be noted that, the mode of sharing during transmitting data flow can be not only non-equivalence load balancing, can be also load balancing of equal value, and the present invention does not limit this.

The embodiment of the present invention provides the method for the data retransmission in a kind of group system, controller in group system obtains after signaling by the first fringe node in described group system, according to described signaling, in described group system, determine at least two transmission paths, and send configuration information to described the first fringe node, so that described the first fringe node, after receiving described configuration information, forwards the Business Stream receiving by described at least two transmission paths.Like this, can be when the maximum bandwidth that individual paths can provide in the required band of transmission data is wider than group system, by determine at least two bandwidth summations in group system, be not less than the transmission path of the required bandwidth of transmission data, thereby utilize this group system can transmit the data that required bandwidth is larger, improved the utilance of group system.
