Designing fast and programmable routers
Historically, the evolution of network routers was driven primarily by performance. Recently, owing to the need for better control over network operations and the constant demand for new features, programmability of routers has become as important as performance. However, today's fastest routers, …

Energy efficient links and routers for multi-processor computer systems
… in today's computer industry, it is clear that routers and interconnection networks are critical components of these multi-processor systems. Therefore, there is a need to obtain accurate area and power models for these critical components so that we can better understand the area and power …

Towards a Common System Architecture for Dynamically Deploying Network Services in Routers and End Hosts
… there is little difference between servers and routers for the purpose of running network services. Services can run anywhere on the Internet. Application service providers will have the freedom to choose the best place to run their code. This thesis presents NetServ, our first step to realize …

Network layer support for overlay networks
… implementation in the network layer (i.e., the routers of the physical network). These primitives support the efficient operation and construction of overlay networks. Packet Reflection allows end hosts to request that routers perform specialized routing and duplication for certain packets. Path …

Virtualized dynamic resource allocation algorithm for the internet Diffserv domains
… resources among service classes within the edge routers of the DiffServ domains dynamically according to their traffic conditions and manages these resources between the DiffServ domains in the event of congestion based on their traffic conditions at the egress routers of the upstream domain and …

On constructing correct and scalable iBGP configurations
… about external destinations to other BGP routers within an AS). Full-mesh iBGP and iBGP with route reflection are the two most common methods of configuring iBGP. Although a full-mesh iBGP guarantees correct and predictable routing, it requires a large number of iBGP sessions-approximately …

Trading structure for randomness in wireless opportunistic routing
… MAC with routing, imposing a strict schedule on routers' access to the medium. Although the scheduler delivers opportunistic gains, it eliminates the clean layering abstraction and misses some of the inherent features of the 802.11 MAC. In particular, it prevents spatial reuse and thus may …

The design of a fast and flexible Internet subscription system using content graphics
… for example, F3 uses an overlay network of routers to distribute messages to subscribers. F3 differs from other systems, however, in its use of preprocessors to analyze messages before routing begins. Preprocessors carry out analyses of the relationships between subscription topics, and …

Hop integrity: a defense against denial-of-service attacks
… three conditions hold for every pair of adjacent routers p and q in the network. First, p does not forward any message to q if q has not been up and reachable. Second, when q receives a message m supposedly from p, then q can check that m was not modified after it was sent. Third, when q receives …

Adaptive communication networks for heterogeneous teams of robots
… and a fixed subset of the agents act as mobile routers. Our goal is to position the team of robotic routers to provide communication coverage to the remaining client robots, while allowing clients maximum freedom to achieve their primary coordination task. We develop algorithms and performance …

Systematically controlling the error rates in variation-prone networks-on-chip for energy efficiency
… that dynamically minimizes the Vdd of groups of routers in a variation-prone NoC using formal control-theory methods. The scheme, called Contra, saves substantial energy while guaranteeing the stability and convergence of error rates. Moreover, the scheme is enhanced with a low-cost secondary …

The application of network coding to multicast routing in wireless networks
… in wireless networks. Network coding allows routers to randomly mix packets before forwarding them. This randomness ensures that routers that hear the same transmission are unlikely to forward the same packets, which permits routers to exploit wireless opportunism with minimal coordination. …

A Study of Locator ID Separation Protocol
… table and Forwarding Information bases on core routers is very high. In addition, the number of BGP messages that are currently being processed by the BGP routers is a worrisome issue. Locator/ID Separation Protocol (LISP) is a recently proposed approach that provides a solution to these …

An Analytical Approach to Inventory Management for Telecommunications Network Equipment
Verizon’s core network relies on routers that use expensive plug-in cards (PICs) to function. PIC failures can cause disruptions to FiOS or wireless service in the surrounding area. Maintaining an appropriate level of spare PICs is important to maintaining high service levels. Due to the high cost …

Integrated Mobility and Service Management for Future All-IP Based Wireless Networks
… future all-IP based wireless networks. If access routers in future all-IP based wireless networks are restricted to perform network layer functions only, we investigate the design of intelligent routers, called dynamic mobility anchor points (DMAPs), to implement per-user regional management in IP …

Decoupling congestion control and bandwidth allocation policy with application to high bandwidth-delay product networks
… XCP does not maintain any per-flow state in routers and requires only a few CPU cycles per packet making it implementable in high-speed routers. Its flexible architecture facilitates the design and implementation of quality of service, such as guaranteed and proportional bandwidth …

MicroCuckoo Hash Engine for High-Speed IP Lookup
… due to the exponential growth in the number of routers. Routers implement the packet classification methodology by determining the flow of the packet, based on various rule checking mechanisms that are performed on the packet headers. However, the memory components like TCAMs used by these …

Network coded wireless architecture
… fundamental switch in network design: instead of routers just storing and forwarding received packets, they mix (or code) packets' content before forwarding. We show through practical systems how routers can exploit this new functionality to harness the intrinsic characteristics of the wireless …

Robustness of bus overlays in optical networks
… Our approach allows optical bypass of some routers during normal operation, thus reducing the load on routers, but makes use of routers in case of failures. We analyze the behavior of our linear and T-shaped systems under average use and failure conditions. We show that certain simple …
