Explanation:

Differential Service Tunnels
Differential Service Traffic Engineering (TE) is an extension of the regular MPLS Traffic
Engineering (MPLSTE)feature. Regular TE does not provide bandwidth guarantees to different
traffic classes. A single bandwidthpool (global pool) is used in regular TE that is shared by all
traffic. In order to support various class of service(CoS), the ability to provide multiple bandwidth
pools is required. These bandwidth pools then can be treateddifferently based on the requirement
for the traffic class using that pool.
In RSVP global and subpools reservable bandwidths are configured on a per interface basis to
accommodateTE tunnels on the node. Available bandwidth from all configured bandwidth pools is
advertised using InteriorGateway Protocol (IGP). RSVP is used to signal the TE tunnel with
appropriate bandwidth pool requirements.
