The following describes how to allocate the bandwidth capacity to the terminal microwave node according to the embodiment of the present invention with reference to the accompanying drawings. In addition to the allocation method described in the embodiments of the present invention, those skilled in the art may also allocate bandwidth capacity to the end microwave node by other means, such as setting a minimum transmission bandwidth in advance in order to ensure no loss of service data. Or set the transmission bandwidth threshold and so on to ensure that no business data is lost, and so on.

2 is a schematic structural diagram of a microwave link according to an embodiment of the present invention. As shown in FIG. 2, the BTS in the figure refers to a Base Transceiver Station of a base transceiver station, and each microwave node in the microwave link is obtained according to an embodiment of the present invention. Network level information and its required bandwidth capacity information include:

The core microwave node is connected to other devices, such as a Radio Network Controller (RNC), and the core microwave node sends the layer to the downstream microwave node (the downstream microwave node includes the monitoring microwave node and the end microwave node). a broadcast source message, where the multicast source message includes: a multicast group ID and network topology information, the multicast group ID is the core microwave node ID, and the network topology information is a network of the core microwave node Hierarchical information;

Sending a multicast group ID to identify the downstream microwave node, indicating that the downstream microwave node is affiliated with the core microwave node, and sending network topology information to each downstream microwave node by layer by layer The microwave nodes are identified at the network level in the microwave link.

After receiving the multicast source message, the downstream microwave node modifies the network topology information to its own network layer information, and sends it to its downstream microwave node to the end microwave node;

That is, the downstream microwave node identifies its own network topology information and continues to send it to the downstream microwave node, so that each microwave node can know its own location and the upstream and downstream microwave nodes connected thereto. .

After receiving the multicast source message, the end microwave node generates a multicast source join message, and sends the message to the upstream microwave node layer by layer. The multicast source join message includes: the multicast group ID, the The end microwave node ID, and the bandwidth capacity information required by the end microwave node itself and its own network topology information, the network topology information is its own network hierarchy information;

After receiving the multicast source join message, the upstream microwave node modifies the bandwidth capacity information and the network topology information in the multicast source join message into its own bandwidth capacity information and network topology information, and sends it to the multicast bandwidth information. The upstream microwave node is up to the core microwave node.

Optionally, after receiving the multicast source message, each end microwave node in the embodiment of the present invention generates a multicast source join message, and the multicast source join message carries its own bandwidth capacity information and its own The network topology information is sent to the upstream microwave node, so that the upstream microwave node can know the bandwidth capacity information of the downstream demand and the network hierarchy, and after all the information is summarized, the microwave is further sent to its upstream microwave. The node performs corresponding processing up to the core microwave node.

The embodiment of the present invention determines the bandwidth capacity information of the end microwave node according to the network layer information of each microwave node and the bandwidth capacity information thereof, and the total bandwidth, including:

ID, port number, and network topology information. Each node can maintain a list of its upstream and downstream through these messages. Each upstream and downstream record in the upstream and downstream lists has a timer enabled, and these messages are received again within the time limit. Then make sure the record is still valid and do not receive these messages within the time limit, then re-update the list. After the upstream and downstream lists are established, bandwidth allocation is performed from the core node to the end node, and then the bandwidth change of all ports is monitored. If any port changes, the bandwidth needs to be re-allocated until the latest bandwidth value is sent to the BTS directly connected to the end node.

FIG. 3 is a schematic flowchart of establishing an upstream and downstream list according to an embodiment of the present invention. In the following, a method for establishing an upstream and downstream list according to an embodiment of the present invention will be described in detail with reference to FIG.

S301. The core microwave node periodically sends a multicast source message.

S302. After receiving the multicast source message, the monitoring microwave node checks whether it has an upstream and downstream list. If not, it establishes an upstream and downstream list, and starts a keep-alive timer, and sends the multicast source message to the terminal microwave node. ;

S303. The end microwave node checks whether the multicast group ID carried by the multicast source message is the same as the multicast group ID to which the end network element is to join. If different, the alarm is reported. If they are the same, check whether there is an upstream or downstream. List, if no, establish an upstream and downstream list, and enable the keep-alive timer, add the base station ID connected to it, and the port directly connected to the base station to its upstream and downstream list, construct a multicast source join message, and carry the end microwave node ID, The network topology information, the multicast group ID, and the bandwidth required by itself are sent to the monitoring microwave node.

S304. After receiving the multicast source join message, the monitoring microwave node writes information such as the ID of the microwave node corresponding to each port downstream thereof to its upstream and downstream list, and each microwave node downstream thereof The bandwidths are added together, and are written into the upstream and downstream lists, and the self-ID, the network topology information, and the multicast group ID generation multicast source join message are sent to the core microwave node;

After receiving the multicast source join message, the monitoring microwave node first detects the legality of the message, and discards it unreasonably. If it is legal, it records in the upstream and downstream lists.

FIG. 4 is a schematic structural diagram of an upstream and downstream list according to an embodiment of the present invention. As shown in FIG. 4, the upstream and downstream list in the embodiment of the present invention includes:

The multicast group ID (also referred to as the multicast source ID) is the ID of the core microwave node;

The monitoring port ID is the port ID directly connected to the upstream of the microwave node.

The bandwidth of the monitoring port is the bandwidth of the upstream and downstream ports corresponding to the microwave node;

The upstream node ID is an upstream microwave node ID corresponding to the microwave node;

The reason for the change in bandwidth is to record the reason for the change in the specific bandwidth;

The network level is the network level corresponding to the microwave node in the microwave link;

The total bandwidth requirement is the sum of bandwidth requirements of all downstream microwave nodes corresponding to the microwave node;

Bandwidth allocation time, used to record the time when the bandwidth was last allocated;

Number of downstream ports, which is the number of ports downstream of the microwave node;

The downstream port records the port information downstream of the microwave node, such as the downstream port ID, bandwidth requirements, and the status of the downstream nodes.

Optionally, the method of the embodiment of the present invention further includes:

The information in all the upstream and downstream lists is monitored. When the upstream and downstream lists are changed, the bandwidth capacity information of the end microwave nodes of the microwave link is re-acquired from the upstream and downstream lists. That is, the bandwidth capacity information in the microwave link is adjusted.

That is, the embodiment of the present invention sends a multicast source message to the downstream microwave node through the core microwave node period. If a microwave node does not have feedback, it is determined that the microwave node does not exist, and the corresponding upstream and downstream list needs to be modified, and The bandwidth capacity information of the end microwave node of the microwave link is re-acquired from the upstream and downstream lists.

The method described in the embodiment of the present invention will be described in detail below with a specific example:

The microwave nodes in the embodiment of the present invention send the multicast group source message and the multicast source join message to each other through the encapsulation layer 2 packet (the actual implementation is not limited to the layer 2 packet, for example, the layer 3 packet). Therefore, in the network topology, each node establishes and maintains an upstream and downstream list, and the bandwidth is dynamically allocated layer by layer through the list. Compared with the related art, the method in the embodiment of the present invention can enable the microwave link. The bandwidth transmission capability is sent to the docking device in real time, which achieves the effect that the services carried by the microwave are not discarded as much as possible, and the service carrying capacity of the microwave device is improved.

1) When a microwave device is configured as a core microwave node, it periodically transmits a multicast source message, for example, setting a transmission period to 10 s, wherein the multicast group message field includes a multicast group ID, and the multicast group ID is The IP address of the device and the network topology information, the network topology information is used to indicate which level the microwave node itself is in the network topology, and the network level of the core node is 1. The multicast source message and the network topology information in the embodiment of the present invention are as follows: Tables 1 and 2 are shown.

2) After receiving the multicast source message, the other microwave nodes first record the network level in the message as their own network level, then look up the downstream port from the upstream and downstream list, and add the multicast source message after the network level is increased by one. Forward to the downstream port.

3) After receiving the multicast source message, the monitoring microwave node first checks whether the multicast group information recorded in the upstream and downstream list is empty, fills in the multicast group information if it is empty, and starts a keep-alive timer for the multicast group. That is, if the multicast source message is not received again at the specified time, the multicast group information is cleared, and the multicast source message is forwarded from the other port intact after the above processing is completed, but the forwarding is not performed. The interface directly connected to the base station is sent. If the multicast group information is not empty, but the received multicast source message is not equal to the filled multicast group ID, the conflict alarm needs to be reported to ensure that there is only one core node in the entire network topology.

4) After receiving the multicast source message, the terminal microwave node first checks whether the multicast group information recorded in the upstream and downstream lists is empty, fills in the multicast group information if empty, and starts a keep-alive timer for the multicast group; After receiving the multicast source message, the end node sends a multicast source join message to the upstream node from the upstream port to the upstream node in unicast mode. As shown in Table 3, the end node carries the multicast group ID, network topology information, and total bandwidth requirement to be joined.

Table 3 multicast source join message structure

5) After receiving the multicast source join message, the monitoring microwave node checks the multicast group information. If the multicast group information is empty, discards the message. If the multicast group information is not empty, the message generates a downstream microwave node record to join. Go to the downstream port record in the upstream and downstream list. Because there may be a scenario of accessing the switch, multiple downstream microwave nodes may exist in one downstream port. The downstream microwave node records the device ID in the downstream port number and the multicast join message as the key value. . Then, the downstream microwave node records the keep-alive timer, and if the join message is not received again, the downstream microwave node is deleted. After the downstream microwave node is established, its bandwidth requirement is added to the total bandwidth requirement in the upstream and downstream lists.

If the downstream microwave node already exists, whether the bandwidth capacity requirement carried in the multicast source join message needs to be changed, and if there is a change, the total bandwidth requirement is updated. The monitoring microwave node needs to re-synthesize the total bandwidth requirements of all the downstream microwave nodes, and then generate a multicast join message to be forwarded from the upstream port to the upstream microwave node. The bandwidth carried is the total bandwidth requirement of the upstream and downstream lists. When the core node receives the join message, it indicates that the entire online downstream list has been established.

6) When the core microwave node establishes a complete upstream and downstream list, it will allocate its own bandwidth to After all the downstream microwave nodes receive the bandwidth allocation message, the downstream microwave node sends the message to the end node. After receiving the bandwidth allocation message, the end node finally sends the bandwidth to the base station for the service capacity it can bear. The ratio of the bandwidth allocated by the microwave node to the downstream device is determined according to the bandwidth value reported by the downstream microwave node. Each of the terminal microwave device ports directly connected to the base station configures the bandwidth requirement according to the service capacity of the base station, and then reports the total bandwidth requirement of the base station to the directly connected upstream node, and reports it to the upstream microwave root node through layer reporting. The root node determines the allocation ratio based on the bandwidth requirements aggregated by each downstream node.

All the downstream port records provide bandwidth requirements. The bandwidth allocation calculation allocates bandwidth according to the ratio. For example, the total bandwidth provided by the monitoring node 1port0 is 60M, and the upstream port of port0 notifies that the allocated bandwidth is 80M, which triggers the bandwidth allocation. The bandwidth requirement of port 1 is 10 M, and the bandwidth requirement of port 2 is 20 M. Then, the bandwidth is allocated to the downstream port in a ratio of 1:2, and 20 M is allocated for port 1 and 40 M bandwidth is allocated for Port 2 .

7) If an upstream and downstream microwave node list is established, the anti-shake timer is turned on for 2 minutes to ensure that a stable upstream and downstream microwave node list is established. If the upstream and downstream lists are not changed after 2 minutes, the monitoring node should trigger a bandwidth calculation and allocation. .

All downstream microwave nodes need to be notified when the monitoring bandwidth changes. When the bandwidth changes, anti-shake function should be provided to prevent frequent changes of the bandwidth of the microwave link in a short period of time. The anti-shake time is 2 minutes. After the microwave bandwidth changes, it needs to maintain a stable state for 2 minutes, and then send a new bandwidth to the downstream direction. Assign a message. For example, in the monitoring node in Figure 5, it is assumed that the bandwidth originally allocated to the core node is 90M, and the bandwidth ratio of the downstream device is 1:1:1, then the available bandwidth for each downstream microwave node is 30M, if the allocation The bandwidth is changed to 120M, and the bandwidth allocated to each downstream microwave node is 40M, which is increased by 33.33%. The bandwidth needs to be allocated to the downstream microwave node. Table 4 is a bandwidth allocation message table according to an embodiment of the present invention.

Table 4 Bandwidth Allocation Message Table

If the upstream or downstream list changes or receives a bandwidth allocation message sent from the upstream, the node is re-proportionally allocated according to the upstream allocated bandwidth and the downstream list information in its upper and lower lists.

It should be noted that, in the embodiment of the present invention, not all bandwidth changes need to be reallocated, and only when the monitoring port bandwidth changes, and the changed bandwidth value is smaller than the bandwidth provided by the upstream node. For example, the bandwidth allocated to the upstream of a microwave node is 50M. When the bandwidth of the self-monitoring port changes to 100M, no redistribution is needed at this time.

After receiving the bandwidth allocation message, the end node searches all the directly connected base station ports according to the downstream list, and sends a bandwidth allocation message to the base station according to the bandwidth requirement of each port, indicating that the microwave node can withstand the best service. size. The message between the microwave and the base station is encapsulated in the 802.3ah message format. For details, see Table 5.
