Network-Driven QOS Components
-
The use of flags in the media access control (MAC) header to establish packet priority in shared-media 802 networks.
-
Enables the marking of relative priority for IP packets. Differentiated Services enable the marking of packets with a code point value, called the DiffServe code point, which is used by network devices such as routers to determine the per-hop behavior (PHB) treatment to which the packet is subjected. Essentially, differentiated services specifies a packet's transmission priority as it passes through each network device on its journey through the network.
-
The mapping of RSVP objects to Layer 2 (per the ISO OSI Model) signaling, such as Frame Relay Network Devices (FRNDs) or ATM interfaces.
-
Manages shared-media network bandwidth. In Windows 2000 Quality of Service, SBM functionality is incorporated into Admission Control Service (ACS).
-
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, and also to senders and receivers.
