A kind of work flow forwarding method flow chart that Fig. 1 provides for the embodiment of the invention.OTN equipment is the OTN equipment with light crossing in the present embodiment.As shown in Figure 1, the method that provides of present embodiment comprises:
Step 11: optical transport network equipment periodic detection all reachable paths take described optical transport network equipment as start node, and add up the flow information of described all reachable paths.
Optical transport network equipment is by sending the mode of detection packet, detection all reachable paths take oneself as start node, for example, the flow of each next-hop device that optical transport network equipment periodic statistics is adjacent, and periodically to each adjacent next-hop device broadcast probe bag, comprise in the detection packet own node identification, oneself next-hop device node identification and oneself arrive the flow information of next-hop device.Each receives the node of detection packet, oneself node identification and own flow information to next-hop device are added in the detection packet that receives and be broadcast to oneself next-hop device, by that analogy, until reach home, namely there is not the node of next-hop device.After detection packet is reached home, terminal point adds the node identification of oneself in the detection packet to, the node identification of detection packet record and the flow information of node are added in the response bag, to respond bag by original route and return to upper hop equipment, until arrive the optical transport network equipment that first sends detection packet.Behind the node identification that comprises a plurality of nodes that first each adjacent next-hop device of optical transport network equipment reception that sends detection packet returns and the response bag of flow information, according to information in each described response bag, determine described optical transport network equipment as all reachable paths of start node, and add up the flow information of every reachable path.Each responds the flow information that comprises each node in a reachable path and this reachable path.
Step 12: when current period receives Business Stream, described optical transport network is in all reachable paths that current period detects, determine each reachable path of described Business Stream, and in the flow information of all reachable paths that current period is added up, determine the flow information of the former forward-path of described Business Stream.
OTN equipment periodic detection all reachable paths take oneself as start node, the reachable path that different cycles detects may be not identical, and the flow information of each reachable path that counts on might be not identical yet.After optical transport network equipment receives Business Stream from upper hop equipment, in all reachable paths that current period detects, according to the destination node of this Business Stream, determine each reachable path of this Business Stream.And in the flow information of all reachable paths that current period counts on, determine the flow information of the former forward-path of this Business Stream.Former forward-path herein is the former overall forward-path of Business Stream.The former forward-path of Business Stream is the forward-path of planning for this Business Stream according to type of service in the network design stage.

If the Business Stream that receives has many reachable paths, then according to the flow information of the former forward-path of described Business Stream, judge whether the flow of the former forward-path of this Business Stream surpasses predetermined threshold value.If surpass, then from all reachable paths of this Business Stream, select another reachable path as alternative path, the wavelength of this Business Stream is converted to wavelength on the alternative path, thereby transmits this Business Stream at alternative path.Particularly, many wavelength are arranged on the alternative path, the wavelength of this Business Stream is converted to wavelength idle on the alternative path, namely from many wavelength, choose a wavelength that is not used by other Business Stream as the wavelength of current business flow.Above-mentioned alternative path can be a reachable path of flow minimum in all reachable paths of Business Stream.If the flow of the former forward-path of this Business Stream does not surpass predetermined threshold value, continue to transmit this Business Stream at the former forward-path of this Business Stream.
If the Business Stream that receives has a reachable path, this reachable path is the former forward-path of Business Stream, do not need to judge that whether the flow on the former forward-path surpasses predetermined threshold value, optical transport network equipment is dealt into next-hop device on the former forward-path with this work flow.
