Implementing an OpenFlow Switch on the NetFPGA platform

by G. Adam Covington, Jad Naous, David Erickson, Nick Mckeown
"... We describe the implementation of an OpenFlow Switch on the NetFPGA platform. OpenFlow is a way to deploy experimental or new protocols in networks that carry production traffic. An OpenFlow network consists of simple flow-based switches in the datapath, with a remote controller to manage several sw ..."

’s complexity to a basic IPv4 router implementation and a basic Ethernet learning switch implementation. We describe the OpenFlow deployment into the Stanford campus and the Internet2 backbone.

Providing Guaranteed Services Without Per Flow Management

by Ion Stoica, Hui Zhang
"... Existing approaches for providing guaranteed services require routers to manage per flow states and perform per ow operations [9, 21]. Such a stateful network architecture is less scalable and robust than stateless network architectures like the original IP and the recently proposed Diffserv [3]. Ho ..."

we use is called Dynamic Packet State (DPS), which provides a lightweight and robust mechanism for routers to coordinate actions and implement distributed algorithms. We present an implementation of the proposed algorithms that has minimum incompatibility with IPv4.

PacketShader: a GPU-Accelerated Software Router

by Sangjin Han, Keon Jang, Kyoungsoo Park, Sue Moon
"... We present PacketShader, a high-performance software router framework for general packet processing with Graphics Processing Unit (GPU) acceleration. PacketShader exploits the massively-parallel processing power of GPU to address the CPU bottleneck in current software routers. Combined with our high ..."
Abstract - Cited by 165 (14 self) - Add to MetaCart
high-performance packet I/O engine, PacketShader outperforms existing software routers by more than a factor of four, forwarding 64B IPv4 packets at 39 Gbps on a single commodity PC. We have implemented IPv4 and IPv6 forwarding, OpenFlow switching, and IPsec tunneling to demonstrate the flexibility

A New Theory of Deadlock-Free Adaptive Routing in Wormhole Networks

by Josc Duato - IEEE Transactions on Parallel and Distributed Systems , 1993
"... Abstract- Second generation multicomputers use wormhole routing, allowing a very low channel setup time and drastically reducing the dependency between network latency and internode distance. Deadlock-free routing strategies have been developed, allowing the implementation of fast hardware routers t ..."

IPv4+4

by Z. Turanyi, A. Valko
"... The IPv4+4 architecture presented in this paper provides an evolutionary approach to the extension of IPv4 address space. It builds on the existence of Network Address Translators (NATs) and private address realms. During and after the transition from IPv4 to IPv4+4 there is no need to change router ..."

Requirements for Label Edge Router Forwarding of IPv4 Option Packets

by D. Smith, J. Mullooly, Cisco Systems, W. Jaeger, T. Scholl - Work in Progress, May 2010. [RFC1633] [RFC2209] [RFC2210] [RFC2747] [RFC2748] [RFC2749] [RFC2961 , 1994
"... This document specifies how Label Edge Routers (LERs) should behave when determining whether to MPLS encapsulate an IPv4 packet with header options. Lack of a formal standard has resulted in different LER forwarding behaviors for IPv4 packets with header options despite being associated with a prefi ..."

Paper On Implementing IPTV Platform with IPv4 and IPv6 Devices

by Jordi Mongay Batallaa, Piotr Krawiecb
"... Abstract—The end of IPv4 addresses is now a reality. Providers not updated to IPv6 will have to hurry up the IPv6 start in its own network. Introduction of IPv6 means not only change of main routers but also change of mentality in op-erators, applications ’ programmers besides end users. Even when f ..."

Design, Implementation and Evaluation of IPv4+4

by Zoltan Turanyi, Andras Valko, Anrew Campbell
"... In this paper we present and evaluate the 4+4 architecture. 4+4 extends the IPv4 address space without requiring changes to existing routers. It builds on the existence of NATs and multiple address realms, but it does not use address translation and provides end-to-end address transparency. Existing ..."

Implementation of IPv6/IPv4 Dual-Stack Transition Mechanism

by Niranjan Ravi , Muppidathi , Saravanan A , Manoranjan Periyasamy
"... ABSTRACT: With the exhaustion of the IPv4 addressing space quickly approaching, it has become a high priority for service providers, enterprises, IP appliances manufacturers, application developers, and governments to begin their own deployments of IPv6. A seamless migration from IPv4 to IPv6 is ha ..."

Inversely, IPv6 may be enabled on interfaces and devices for which IPv4 support is no longer needed. In this project the Dual-Stack transition mechanism is implemented in GNS3 (Graphical

Concise Lookup Tables for IPv4 and IPv6 Longest Prefix MatchinginScalableRouters

by Fong Pong, Senior Member, Nian-feng Tzeng
"... Abstract—We present a distinct longest prefix matching(LPM) lookup scheme able to achieve exceedingly concise lookup tables (CoLT), suitable for scalable routers. Based on unified hash tables for handling both IPv4 and IPv6 simultaneously, CoLT excels over previous mechanisms in: 1) lower on-chip st ..."
