In recent years, a variety of unicast and multicast routing protocols for Mobile Ad hoc wireless NETworks (MANETs) have been developed. The Zone Routing Protocol (ZRP) is a hybrid unicast protocol that proactively maintains routing information for a local neighborhood (routing zone), while reactively acquiring routes to destinations beyond the routing zone. In this paper, we extend ZRP for appl...

IP has become the dominant networking paradigm for the present century. The evolution towards an all-IP core network infrastructure continues, with an enriched IP layer often implementing the networking functionalities directly on top of WDM (Wave Division Multiplexed) links. Furthermore, IP over switched 1/10 GigaEthernet is replacing the traditional, relatively slow-speed, access technologies...

When given a plan by a satisficing planner, it is usually not intuitive as to how close it is to the optimal solution. However, real world planning problems often require some metric on which to optimize, especially when goals are soft and resource constraints are involved, as is the case in oversubscribed planning problems. Unfortunately, little effort is given to find how close any plan may b...

For networks providing a specific level of service guarantees, capacity planning is an imperative part of network management. Accurate dimensioning is especially important in DiffServ networks, where no per-flow signaling or control exists. In this paper, we address the problem of capacity planning for DiffServ networks with only Expedited Forwarding (EF) and best effort (BE) traffic classes. T...
