The Input Buffer Use By Port Report represents a summary of each node’s port input buffer
usage during the simulation. The node is connected to each link via an interface port. Each
port has an input buffer, the size of which is defined on the port (edit the arc that connects
the link to the node to see this). The amount of input buffer space on the node is the sum
total of all the port input buffer spaces. In addition, the node has an upper maximum on the
total amount of input buffer space that can be in use at one time across all ports. This is
defined on the node parameters screen.
When a packet is received, first the port input buffer is checked to see if there is space. If
so, the node input limit is checked to see if the node in total has space. If both tests succeed,
the packet is received into the input buffer.
Node Name
Connected Links
Packets Accepted
Packets Blocked
The name of the node receiving packets.
The name of the link whose input port is being reported.
The number of packets received into the port input buffer.
The number of packets blocked at this port input buffer.
Buffer Use - Average, Std Dev, Max
The average, standard deviation and maximum amount of buffer space
in use at this port input buffer described in either packets or bytes.
