I.e., the present invention sends multicast source message by the core microwave node cycle to microwave node downstream, if certain microwave node does not feed back, then determine that this microwave node does not exists, then need to revise corresponding upstream and downstream list, and reacquire the bandwidth capability information of the end microwave node of microwave link.
For a specific example method of the present invention will be described in detail below:
(actual realization is not limited to layer two message by encapsulated layer two message between the microwave node of the present invention, such as, can also is that layer three message) send mutually multicast group source message, multicast source adds message, it is achieved thereby that each node is all set up and safeguards a upstream and downstream list in network topology, and by this list successively dynamic bandwidth allocation, compared with prior art, method of the present invention can make the bandwidth transmission capability of microwave link be sent to the service of connection devices in real time, reach the effect that the business of microwave carrying is not dropped as far as possible, improve the service bearer ability of microwave equipment.
1) after a microwave equipment is configured to core microwave node, its cycle sends multicast source message, as, set the transmission cycle as 10s, wherein, multicast group message field (MFLD) includes multicast group ID, multicast group ID is himself device IP, and network topological information, and network topological information is used for representing that microwave node is from being in which level in network topology, the network layer of core node is 1, and the multicast source message of the present invention and network topological information are as shown in Tables 1 and 2.

| Title | Type | Value |
| Multicast group ID | WORD32 | Core node IP |
| Network topological information | WORD32 | Self IP |
Table 2, network topological information structure
| Title | Type | Value |
| Multicast group ID | WORD32 | Core node IP |
| Send network topological information | WORD32 | Self IP |
| Network layer | WORD32 | The network layer received adds 1 |
2) after other microwave nodes receive multicast source message, first the network layer in message is added 1 and be recorded as own net level, then network layer is added a restructuring message from upstream and downstream list, searches the forwarding of downstream port record port basis.
3) after monitoring microwave node receives multicast source message; whether the multicast group information first looking at upstream and downstream record is empty; multicast group information is filled in if sky; and open a keep-alive intervalometer for this multicast group; that is, if the appointment time receives multicast source message the most again, then multicast group information is emptied; after completing above-mentioned process, this multicast source message is remained untouched from other port and forward, do not send to the interface direct-connected with base station during forwarding.If multicast group information is not empty, but the multicast source message received is unequal with multicast group ID filled in, and needs to report collision alert to ensure only one of which core node in whole network topology.
4) after end microwave node receives multicast message; whether the multicast group information first looking at upstream and downstream record is empty; multicast group information is filled in if sky; and open keep-alive intervalometer for this multicast group; multicast source addition message is sent with mode of unicast to from upstream port upstream nodes after endpoint node receives multicast message; as shown in table 3, multicast group ID to be added, network topological information, total bandwidth need are carried.

| Title | Type | Value |
| Multicast group ID | WORD32 | Core node IP |
| Network topological information | WORD32 | Self IP |
| Bandwidth demand | WORD32 | Bandwidth demand in upstream and downstream list |
5) after monitoring microwave node receives multicast source addition message, check multicast group information, if multicast group information is sky abandons this message, if multicast group information non-NULL, one downstream microwave nodes records of this message generation is joined the downstream port record in upstream and downstream list.Owing to there may be the scene of access switch, therefore can there is a plurality of downstream microwave node in a downstream port, downstream microwave nodes records is with the device id in downstream port numbers and multicast addition message as key assignments, and so far a downstream microwave node finds complete.Then it is that this downstream microwave nodes records opens keep-alive intervalometer, if the appointment time receives this addition message the most again, deletes this downstream microwave node.Its bandwidth demand is added in the total bandwidth need in upstream and downstream list after setting up by downstream microwave node.
If this downstream microwave node has existed, need to compare whether bandwidth demand changes, if changing renewal total bandwidth need.Monitoring microwave node needs again to collect the total bandwidth need of all downstream microwave nodes, then generates a multicast addition message and is transmitted to the microwave node of upstream from upstream port, and the bandwidth carried is exactly the total bandwidth need of upstream and downstream list.After core node receives addition message, represent that the whole network upstream and downstream list has built up complete,
6) can be by the bandwidth of himself by distributing to all downstream microwave nodes after core microwave node sets up complete upstream and downstream list, downstream microwave node is further continued for issuing after receiving bandwidth allocation, successively issues with this until endpoint node.This bandwidth is finally issued base station after receiving bandwidth allocation and is represented its volume of business that can bear by endpoint node.Microwave node is that the bandwidth value reported according to downstream microwave node determines to the ratio of upstream device distribution bandwidth.Each end microwave equipment port direct-connected with base station is according to the volume of business size configured bandwidth demand of base station, then the total bandwidth need collecting self reports direct-connected upstream node, through reporting the microwave root node being aggregated into most upstream layer by layer, the bandwidth demand that root node collects up according to each downstream node determines allocation proportion.
All downstream port records are each provided with bandwidth demand, bandwidth distribution calculates and proportionally distributes bandwidth, the total bandwidth that such as monitor node 1port0 provides is 60M, the a width of 80M of band of the upstream port notice distribution of port0, so can trigger the distribution of this bandwidth, the bandwidth demand that bandwidth demand is 10M, port2 assuming downstream port port1 is 20M, then be that downstream port distributes bandwidth according to the ratio of 1:2, for port1 distribution 20M, distributes 40M bandwidth for Port2.
7) if establishing a upstream and downstream microwave node listing, open stabilization timer 2 minute, ensure foundation is stable upstream and downstream microwave node listing, if upstream and downstream list afterwards in 2 minutes is not changed in monitor node and should trigger a bandwidth calculation and distribution.
Need to notify all downstream microwave nodes when monitoring bandwidth and changing.Should possess stabilization function during bandwidth change, in preventing the short time, microwave link bandwidth frequently changes, and the stabilization time is 2 minutes, after i.e. Microwave bandwidth changes, needs to keep the stable state of 2 minutes, and roam all around the would is to sending new bandwidth allocation still further below.Such as monitor node in Fig. 5, it is assumed here that the bandwidth that core node originally allocated it is 90M, the allocation proportion of upstream device bandwidth is 1:1:1, the available bandwidth so provided for each downstream microwave node is 30M, if distribution bandwidth become 120M, then can be each downstream microwave node distribute bandwidth be 40M, add 33.33%, needing again to distribute bandwidth to downstream microwave node, table 4 is the bandwidth allocation table of the present invention.
Table 4 bandwidth allocation table
| Multicast group ID | WORD32 | Core node IP |
| Bandwidth change network topological information | WORD32 | Trigger the device IP that bandwidth reassigns |
| Link depth | WORD32 | Self and trigger reassignment equipment network layer interval |
| Available bandwidth | WORD32 | The bandwidth of upstream node distribution |
If upstream and downstream list changes or receives the bandwidth allocation that upstream is sent, then this node distributes bandwidth according to the upstream in self upper and lower list and downstream list information is pro rata distributed again.
It should be noted that the not every bandwidth of the present invention changes and is required for redistributing, only change when monitoring client port band width, and change after bandwidth value less than upstream node provide bandwidth time just reassignment.Such as one microwave node upstream is a width of 50M of band of its distribution, when self monitoring client port band width is changed to 100M, now need not reassign.
After endpoint node receives bandwidth allocation, according to all of direct-connected base station port of downstream list lookup, and the bandwidth demand configured according to each port sends bandwidth allocation in proportion to base station, represents the best service size that this microwave node can bear.Message between microwave and base station uses the encapsulation of 802.3ah message format, referring specifically to table 5.
Message envelope format between table 5 microwave and base station
