The HPR/IP connection network table. Values for TOS Precedence at the connection network level override those at the level of the containing port. If there is no entry in this table for a given connection network, then that connection network inherits its TOS Precedence values from its port. A node may have connections to a given connection network through multiple ports. There is no provision in the HPR-IP architecture for variations in TOS Precedence values for a single connection network based on the port through which traffic is flowing to the connection network. Thus an entry in this table overrides the port-level settings for all the ports through which the node can reach the connection network.
