QoS - QoS Models
4 important questions on QoS - QoS Models
What are the 3 diffrent QoS implementation models?
2. Integrated Services (IntServ) Applications signal the network to make a bandwidth reservation and that they require special QoS treatment.
3. Differentiated Services (DiffServ) The network identifies classes that require special QoS treatment.
How does the QoS model of IntServ work?
To be able to accomplish this the IntServ model needs to support, build and maintain RSVP path state for every flow.
How does the IntServ QoS model establish Reservations?
The data in the RSVP Path messages is stored in the RSVP Path State of each node.
The receiver responds with an RSVP Reservation Request (RESV). On each hop on the return path it will reserve the bandwidth.
