Connection Manager and Router
The connection manager responds to connection requests by scheduling
and allocating the connection router path resources. When a link is
established, the linked phys can communicate and transfer data. The
connection router connects signals between pairs of phys, or between a
phy and an internal port (SMP or STP) with minimal latency.
The connection manager establishes a connection when a link requests
a connection. The connection manager looks at all connection requests
and establishes as many connections as possible. The connection
manager uses a distributed arbitration mechanism. Once a connection is
established, the connected links communicate with each other and pass
the receive/transmit data stream.
Registers within the connection manager are readable and writable
through the register bus interface.
