Status of this Memo
This document specifies an Internet standards track protocol for the
Internet community, and requests discussion and suggestions for
improvements. Please refer to the current edition of the "Internet
Official Protocol Standards" (STD 1) for the standardization state
and status of this protocol. Distribution of this memo is unlimited.
This memo defines a set of general control and characterization
parameters for network elements supporting the IETF integrated
services QoS control framework. General parameters are those with
common, shared definitions across all QoS control services.
This memo defines the set of general control and characterization
parameters used by network elements supporting the integrated
services framework. "General" means that the parameter has a common
definition and shared meaning across all QoS control services.
Control parameters are used by applications to provide information to
the network related to QoS control requests. An example is the
traffic specification (TSpec) generated by application senders and
Characterization parameters are used to discover or characterize the
QoS management environment along the path of a packet flow requesting
active end-to-end QoS control. These characterizations may
eventually be used by the application requesting QoS control, or by
other network elements along the path. Examples include information
about which QoS control services are available along a network path
and estimates of the available path bandwidth.
Individual QoS control service specifications may refer to these
parameter definitions as well as defining additional parameters
specific to the needs of that service.
Parameters are assigned machine-oriented ID's using a method
described in [RFC 2216] and summarized here. These ID's may be used
within protocol messages (e.g., as described in [RFC 2210]) or
management interfaces to describe the parameter values present. Each
parameter ID is composed from two numerical fields, one identifying
the service associated with the parameter (the
the other (the
Because the definitions of the parameters defined in this note are
common to all QoS control services, the
the parameters defined here are assigned from the "general
parameters" range (1 - 127).
