This document provides common terminology and metrics for benchmarking the performance of sub-IP layer protection mechanisms. The performance benchmarks are measured at the IP layer; protection may be provided at the sub-IP layer. The benchmarks and terminology can be applied in methodology documents for different sub-IP layer protection mechanisms such as Automatic Protection Switching (APS), ...

In the next generation backbone networks, IP/MPLS over optical networks, the ability to maintain an acceptable level of reliability has become crucial since a failure can result in a loss of several terabits of data per second. Although routing schemes with protection exist, they generally relate to a single switching layer: either wavelength or packet switching oriented. This paper presents a ...

In this study Hinted Cell Switching is introduced as a new alternative to the Mobile IP advertisement based movement detection methods. It is a method that relies on “hints” generated during subnetwork layer hand-offs for reacting faster to Mobile IP hand-offs. In this study the performance of Hinted Cell Switching is compared through the use of simulations against those of advertisement based ...

The ubiquity of IP associated with the acknowledgment of ATM as a key switching technology has motivated an increasing interest towards the design of a more eecient way of operating IP over ATM networks. This approach is known under the name Label Swapping. A few studies have addressed the primary issue of providing simultaneously quality of service and multicast. We propose a solution where we...

In modern IP networks, processing cost in network nodes is considered as a bottleneck. This problem is tackled with traffic based IP switching. The performance of traffic based IP switching depends heavily on flow classification. We demonstrate a method to evaluate the performance gains available with this technique with an optimal nondeterministic classifier giving a practical lower bound for ...

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...

In this work we compare different methods for router workload deduction and flow classification schemes. Gigabit-routing solutions and different schemes of integrated switching and routing (Internet protocol (IP) switching) have emerged. Several flow classification schemes to be used in traffic-controled IP switching are presented and evaluated. As a new alternative, the ‘Learning Vector Quanti...

ince the Internet was opened to commercial traffic in 1992, it has grown rapidly from an experimental research network to an extensive public data network. Demand is pushing the capabilities of today's Internet in several dimensions: transmission bandwidth, number of hosts, geographic size, and traffic volume. At the same time, the Internet is evolving from best-effort service toward an integra...

Optical burst switching (OBS) has been proposed as the next generation optical network for grid computing. In this paper, we envision a heterogeneous Grid served by an Optical Burst Switching framework, where grid traffic co-exists with IP and/or a 10 GE based traffic to achieve economy of scale. This paper addresses the latency that Grid jobs experience in OBS networks. The injection of jumbo ...
