We introduce the concept of mobility-based communication in ad hoc networks, meaning that the packet transport is performed mainly by the nodes’ movement. We outline a model for such networks, utilizing a stochastic model for the geographical location of the nodes. A test case is defined in which three strategies for packet forwarding are presented and evaluated.

We demonstrate the first asynchronous 2x2 optical packet switch capable of synchronizing, buffering, and forwarding 10 Gb/s packets generated from independent transmitters with better than 99% packet recovery measured using a burst mode receiver. ©2010 Optical Society of America OCIS codes: (060.1810) Buffers, couplers, routers, switches, and multiplexers; (230.4480) Optical amplifiers

We present a novel scheme for packet forwarding in optical packet-switched networks and we further demonstrate its good scalability through simulations. The scheme requires neither header modification nor any label distribution protocol, thus reducing component cost while simplifying network management.

Networks are expanding very fast and the number of clients is increasing dramatically, this causes the router forwarding table to become very large and present more demand on faster router operations. In this paper, we address the problem of packet forwarding in the routers aiming to increase the speed of address lookup and minimize the memory required for storing the forwarding table. We propo...

We consider the problem of a packet multiplexor that receives packets from multiple input flows, then forwards them to a single output channel. The multiplexor ensures a predefined forwarding rate for each flow. This is achieved as follows. The multiplexor assigns a timestamp to each received packet. When the channel becomes idle, the multiplexor forwards the packet with the smallest timestamp....

Vehicular Ad Hoc Networks (VANETs) represent promising technologies of cyber-physical systems for improving driving safety and communication mobility. Due to the highly dynamic driving patterns of vehicles, effective packet forwarding, especially for time sensitive data, has been a challenging research problem. Previous works forward data packets mostly utilizing statistical information about r...

In a mobile ad hoc network (MANET), the nodes act both as traffic sources and as relays that forward packets from other nodes along multi-hop routes to the destination. Such networks are suited to situations in which in a wireless infrastructure is unavailable, infeasible, or prohibitively expensive. However, the lack of a secure, trusted infrastructure in such networks, make secure and reliabl...

The requirements on IP routers continue to increase, both from the control plane and the forwarding plane perspectives. To improve scalability, flexibility, and availability new ways to build future routers need to be investigated. This paper suggests a decentralized, modular system design for routers, based on control elements for functionalities like routing, and forwarding elements for packe...

This document provides an overview of a novel approach to network layer packet forwarding, called tag switching. The two main components of the tag switching architecture forwarding and control are described. Forwarding is accomplished using simple label-swapping techniques, while the existing network layer routing protocols plus mechanisms for binding and distributing tags are used for control...

The exponential growth in Internet traffic has motivated the development of a new breed of microprocessors called Network Processors, which are designed to address the performance problem resulting from exploding Internet traffic. The development efforts of these network processors concentrate almost exclusively on streamlining their data-paths to speed up network packet processing, which mainl...
