The QoS protocols -

ReSerVation Protocol (RSVP): Provides the signaling to enable
network resource reservation (otherwise known as Integrated
Services). Although typically used on a per-flow basis, RSVP is also
used to reserve resources for aggregates (as we describe in our
examination of QoS architectures).


• Differentiated Services (DiffServ): Provides a coarse and simple way
to categorize and prioritize network traffic (flow) aggregates.

• Multi Protocol Labeling Switching (MPLS): Provides bandwidth
management for aggregates via network routing control according to
labels in (encapsulating) packet headers.

• Subnet Bandwidth Management (SBM): Enables categorization and
prioritization at Layer 2 (the data-link layer in the OSI model) on
shared and switched IEEE 802 networks.
