Differentiated service (Diffserv) is a set of technologies used to enable the provisioning of class-based, differentiated quality of service. One of the essential building blocks to realize Diffserv is the use of traffic conditioning mechanisms to support the required forwarding behavior. In this paper, a generic model for traffic conditioning is proposed. The generic traffic conditioner (GTC) ...

| We motivate and formally deene dynamic multipath routing and present the problem of packet forwarding in the multipath routing context. We demonstrate that for multipath sets that are suux matched, forwarding can be eeciently implemented with (1) a per packet overhead of a small, xed-length path identiier, and (2) router space overhead linear in K, the number of alternate paths between a sour...

Multiprotocol Label Switching (MPLS) fasten the speed of packet forwarding by forwarding the packets based on labels and reduces the use of routing table look up from all routers to label edge routers(LER) , where as the label switch routers (LSRs) uses Label Distribution Protocol (LDP) or RSVP (Resource reservation Protocol) for label allocation and Label table for packet forwarding . Dynamic ...

As network transmission speeds increase, packet streams increasingly uncover fine details of the interior behavior of router hardware and software. This behavior reveals itself as a set of harmonic effects, as interior clocks periodically interrupt packet forwarding, and interior queues periodically empty and fill. We examine this behavior with a Linux-based router employing a variety of gigabi...

In this paper, we present an efficient IP packet forwarding methodology and architecture. This is achieved by partitioning the lookup table into the smaller ones for each output port and allowing a forwarding engine to process them in parallel. This effectively reduces the complexity of finding “the longest prefix match” problem to “the first prefix match” problem.

These days, commodity-off-the-shelf (COTS) hardware and software are used to build high-end and powerful workstations and servers to be deployed in today’s local area networks of private homes and smallto medium-sized business. Typically, these servers are multipurpose and shared running networking functionalities involving IP packet forwarding in addition to other CPU intensive applications. I...

Due to the dynamism of topology, sharing of bandwidth and constraint of resources in wireless nodes, the provision of quality of service (QoS) for routing in mobile ad hoc networks (MANETs) presents a great challenge. Security is another crucial aspect of providing QoS since the existence of malicious nodes present all kinds of threats to MANETs. Although a number of mechanisms have been propos...

In Delay and Disruption Tolerant Networks (DTNs) [1], packet forwarding is based on the store-carry-and-forward paradigm. Basically, each node has a buffer and is able to store messages persistently, until an appropriate forwarding opportunity arises. In addition, several routing protocols for DTNs employ message replication as an alternative to increase the message delivery rate. The role of a...
