Multidomain traffic engineering (TE) has the potential not only of guaranteeing the quality of service (QoS) to connections spanning multiple domains but also of effectively utilizing intradomain resources. The hierarchical Optical Internetworking Forum (OIF) External Network-to-Network Interface (E-NNI) control plane platform has emerged as a promising candidate aiming at guaranteeing multidomain...
When you design networks that transport voice over packet, frame, or cell infrastructures, it is important to understand and account for the delay components in the network. If you account correctly for all potential delays, it ensures that overall network performance is acceptable. Delay guarantees are critical to real-time applications. To ensure the end-to-end delay guarantee of a flow, the previous...
Wireless ad hoc networks using omni-directional antennas do not scale well due to interference between nearby nodes. Maintaining the QoS of the communications in this type of network is a difficult task. Using multiple narrow beam directional antennas alleviates this problem at the expense of connectivity. Multi-beam smart antennas allow the network topology to be adjusted dynamically by adjusting...
