Ubiquity can be achieved through multi-technology mobile terminals (nodes), which enables network users to access any available network. In addition, such nodes extend network coverage by relaying traffic for each other. However, to exploit the benefits of the internetworking, it is desirable to have appropriate traffic engineering (TE) mechanisms. Taking into account the co-existence of different physical and Medium Access Control (MAC) layer standards in the individual networks, the multi-hop communication capability and the impairment-prone wireless medium, TE becomes challenging.
- ItemOpen AccessMulti-stage queuing with iterative probabilistic scheduling of IP traffic for QoS provisioning(2006) Salami, Oladayo M; Chan, H Anthony; Dlodlo, Mqhele EQueuing and scheduling are packet processing functions which provide quality of service (QoS) at the first level of the QoS architecture where routers reside. With the continued increase in network speed, queuing and scheduling of traffic needs to be performed at higher speed. In addition, processing co-existing IP traffic from different applications requiring QoS may complicate these functions. Virtual Output Queuing (VOQ) is a strategy that can queue traffic at line rate and achieve 100% throughput with an effective scheduling algorith. It maintains a separate queue for each output port at each inputport. With N input ports and N output ports in the router ther are N² such virtual output queues at the input. The challenge is to schedule the packets at the head on these N² queues.
