Network-Driven GQOS Components

[This is preliminary documentation and subject to change.]

802.1p

The use of flags in the media access control (MAC) header to establish packet priority in shared-media 802 networks.

IP Precedence

Establishes priority for IP packets, used to establish packet priority in Layer 3 switches (routers).

L2 Signaling

The mapping of RSVP objects to Layer 2 (per the ISO OSI Model) signaling, such as Frame Relay Network Devices (FRNDs) or ATM interfaces.

Subnet Bandwidth Manager (SBM)

Manages shared-media network bandwidth. In GQOS, SBM functionality is incorporated in the Admission Control Service (ACS).

Resource Reservation Protocol (RSVP)

Carries and disseminates QOS information to QOS-aware network devices along the path between a sender and one or more receivers for a given flow.
