Network Layer (Congestion and QoS)
... A lighter approach to QoS IntServ is very powerful but has some severe drawbacks: - There is a setup phase, this cases delay in starting data flow. - Routers need to maintain per-flow state. This approach is flow-based and not very scalable. - Complex router-to-router exchange of flow information. ...
