Resource Manager
An SCMP CONNECT request includes a flowspec that lists the communications
resources required by the proposed stream.
On a Bay Networks router, an ST2 agent that receives a connect request from an
agent upstream passes the flowspec to the local Resource Manager.
The Resource Manager allocates and guarantees the resources required by the
stream.
For information on the Resource Manager, see Configuring Line Services.
ST2 Features
Table 5-1 lists ST2 features and indicates the ones called out in RFC 1190,
“Experimental Internet Stream Protocol, Version 2,” and the ones supported by
