Description

Currently the number of network buffers in LocalBufferPool for SingleInputGate is limited by a * <number of channels> + b, where a is the number of exclusive buffers for each channel and b is the number of floating buffers shared by all channels.

Considering the credit-based flow control feature, we want to create a fix size buffer pool used to manage the floating buffers for SingleInputGate. And the exclusive buffers are assigned to InputChannel directly.
