QoS Services
Two types of QoS architectures are currently available: Integrated Services (IntServ) and Differentiated Services (DiffServ). IntServ is designed to provide guaranteed resources on the network for applications. For example, a network application via Resource Reservation Protocol (RSVP), a signaling protocol, requests specific bandwidth from the network for a given flow. RSVP visiting each network hop toward the IP destination address will attempt to allocate network bandwidth resources. If the results are positive, the application can send its traffic on the network. RSVP in addition to bandwidth allotment can also help allocate resources for delay-sensitive applications as well as provide the traditional best-effort service. The ...
