Class of Service
Different telecommunications applications require different Qualities of Service. For example, if a telecommunications service provider decides to offer different qualities of voice connection, then a premium voice connection will require a better connection quality compared to an ordinary voice connection. Thus different Qualities of Service are appropriate, depending on the intended use. To help telecommunications service providers to market their different services, each service is placed into a specific class. Each Class of Service determines the level of service required.
To identify the Class of Service for a specific service, the network’s switches and routers examine the call based on several factors. Such factors can include:
- The type of service and priority due to precedence
- The identity of the initiating party
- The identity of the recipient party
