Example
[0056] The first embodiment: AAL5 is a connection-oriented service. When data transmission is required, a permanent virtual circuit (PVC) (Permanent Virtual Circuit) between the sending end and the receiving end is first established, and the data is transmitted through the permanent virtual circuit.
[0057] When the present invention is applied to AAL5 data transmission, the buffer pool is first divided into a predetermined number of private sub-buffer pools and shared sub-buffer pools; due to the connection-based data transmission method, both ends of the channel have the same network Identification (VPI (Virtual Pass Identifier, virtual path identifier), VCI (Virtual Channel Identifier, virtual channel identifier)). Therefore, the corresponding relationship between the data transmission channel and the private sub-buffer pool can be set according to the network identifier.
[0058] The method of using each private sub-buffer pool is the same as the method of dynamically using t...

[0065] The second embodiment: SSCOP (Service Specifical Conection Orientated Protocol, connection-oriented protocol for specific services) IPOA (IP Over ATM) is a different upper-layer service based on AAL5 connections, and the protocol groups are SSCOP / AAL5 / ATM, IPOA / AAL5 / ATM. .
[0066] In order to prevent different services from affecting each other, it is usually necessary to allocate different buffer areas for different types of services. When the present invention is applied to these two services, the buffer pool is first divided into two private sub-buffer pools and one shared sub-buffer pool for the two business types; then the private sub-buffer pools are allocated to For the channel corresponding to each service, for example, pool 1 is allocated to SSCOP, pool 2 is allocated to IPOA, and pool 3 is a shared buffer.
[0067] When data transmission is required, first find the corresponding private sub-buffer pool according to the service type of the PVC, and then check whet...
Example
[0069] The third embodiment: In a communication system, there are different trunk lines between different network nodes. In order to ensure that data from different ports does not interfere with each other, it is necessary to allocate different buffer areas for data from different physical ports during transmission. . When the present invention is applied, different private sub-buffer pools are allocated for data from different physical ports, and a buffer area is allocated as a shared buffer for each physical port. The current port types include trunk mapping ports, connection ports between circuit boards, and optical / electrical interfaces. Therefore, the correspondence between the data transmission channel and the private sub-buffer pool can be set according to the port type. The specific management method of the buffer is consistent with the previous example.
[0070] When data transmission needs to be performed, first find the corresponding private sub-buffer pool according to...
