Integrated services is a ---------------------- QoS model designed for IP [CO5]

Integrated Services is a Quality of Service (QoS) model designed for Internet Protocol (IP). This model is also known as IntServ. It provides specific quality guarantees to individual sessions based on resource reservation.

Here are the steps to understand this:

1. Integrated Services (IntServ): This is a model developed to provide quality of service (QoS) on networks, specifically for Internet Protocol (IP).

2. Quality of Service (QoS): This is a measure of the performance of a service such as a telephony or computer network or a cloud computing service. It guarantees a certain level of a specified resource to a service or a session.

3. Internet Protocol (IP): This is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries.

4. The IntServ model works by explicitly reserving network bandwidth for a particular service or application. This reservation remains in place for the duration of the session, ensuring that the required level of service is maintained.

5. The main advantage of the IntServ model is that it can guarantee QoS by reserving resources. However, it does not scale well and can be complex to implement in large networks.

So, in summary, Integrated Services is a QoS model designed for IP that provides specific quality guarantees to individual sessions based on resource reservation.
