Asynchronous Transfer Mode Communication Method Division and Reassembly of Network Interface Card Memory Usage by Using Receive Buffer for Each Connection in the Subordinate Layer

摘要

The present invention relates to a method and apparatus for determining the size of a maximum transmission packet by reflecting the characteristics of a connection at the time of connection acceptance in a division and reassembly (SAR) sublayer of an asynchronous transfer mode communication method network interface card (NIC) Asynchronous transmission mode that can reduce the waste of memory by using buffer size according to traffic characteristics and to support a lot of connections. Partition and Reassembly of Network Interface Card Separate reception buffer is used for each connection in the sublayer. A method of using memory in a sub-layer (SAR) sublayer of an asynchronous transfer mode communication network interface card (NIC), the method comprising the steps of: A first step of determining the size of the image; And a second step of allocating a memory corresponding to the pointer after the pointer to the buffer of the transport packet TS is recorded in buffering of the memory.
