Common Fixed Structure QoS Models

IntServ:

•Negotiate Nodal Resource.

•E2E Reservation.

•Resources Blocked till released.

•Sensitive to mobility, and net-work dynamics.

•Not scalable.

•Requires reliable per link behavior.

DiffServ:

•Domain Resources Agreements.

•Policy Based Resources Sharing.

•Undetermined behavior with mobility, and net-work dynamics.

•Require heavy weight gateways.

•Reliable per domain behavior.
