the ip lookup process is a key bottleneck in routing due to the increase in routing table size, increasing traıc and migration to ipv6 addresses. the ip address lookup involves computation of the longest prefix matching (lpm), which existing solutions such as bsd radix tries, scale poorly when traıc in the router increases or when employed for ipv6 address lookups. in this paper, we describe a ...

Sites with the same priority are gathered in the same group. Communication inside a group is organized in a logical rooted tree structure. The tree’s root is the site that last held the token. This organization is similar to that of Raymond's algorithm. For its external communications, a group resorts to an external supplementary element: a router. This router manages external communications. T...

Received Nov 21, 2017 Revised Jan 29, 2018 Accepted Feb 19, 2018 The Internet itself is a worldwide network connecting millions of computers and less significant networks. Computers communicated by routers. Crucial the role of a router is to our technique of communicating and computing. Routers are situated at gateways, the spaces where two or more networks connect, and are the decisive device ...

The IP Lookup Process is a key bottleneck in routing because of increasing routing table sizes, increasing traffic, higher speed links, and migration to 128-bit IPv6 addresses. The IP routing lookup involves computation of the best matching prefix (BMP) for which existing solutions, such as BSD Radix Tries, scale poorly when traffic in the router increases or when employed for IPv6 address look...

This application note describes a reference design for a mixed-version IP router (MIR) servicing up to four gigabit Ethernet ports. MIRs are useful where several gigabit Ethernet networks are operating with a mixture of IPv4 and IPv6 hosts and routers attached directly to the networks, and further nodes reached via the routers. A particular benefit of an approach based on the Virtex-II ProTM fa...

A fully adaptive router with hybrid buuers at the input and output channels was designed, which improves the throughput of its input buuer counterpart by up to 40% and has only 10% higher base la-tency. An in-depth analysis of diierent router buuer organization was carried out for a toroidal network, which uses either a deterministic (DOR) or a fully adaptive routing scheme. Each proposal is de...

This paper introduces a modeling framework for network processing systems. The framework is composed of independent application, system and traffic models which describe router functionality, system resources/organization and packet traffic, respectively. The framework uses the Click Modular router to describe router functionality. Click modules are mapped onto an object-based description of th...

Routers and Switches are key building blocks of global networks. Data rates in the range of multiple gigabit per second are owing trough them and emerging router functionalities (active networking, layer 4 switching,. . .) require fast and eecient routers. Therefore, hardware support is needed in order to speed up the performance critical forwarding task. This paper presents a exible hardware s...
