> 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 implement a new fixed size
buffer pool type used to manage the floating buffers for {{SingleInputGate}}. 
> Compared with {{LocalBufferPool}}, this is a non-rebalancing buffer pool which will not
participate in redistributing the left available buffers in {{NetworkBufferPool}}.
