Method of managing communication buffers for a plurality of communication layers and node employing the same

A node comprising:

• a processor including a memory, a transceiver and a communication routine,
• wherein said memory includes a plurality of communication buffers, and
• wherein said communication routine includes a buffer manager adapted to manage said communication buffers and a plurality of communication layers having a physical layer associated with said transceiver, said buffer manager being independent of said communication layers, one of said communication layers being adapted to request one of the communication buffers from the buffer manager, said buffer manager, responsive to said request, being adapted to provide to said one of the communication layers an identification of said one of the communication buffers, said one of the communication layers being adapted to employ said one of the communication buffers, and being adapted to release said one of the communication buffers to the buffer manager or to indicate said one of the communication buffers to another one of said communication layers.
