One of the main issues of Mobile IPv6 is handover latency that causes service disruption time. Although plenty of proposals significantly reduce the service disruption time, they suffer from redundant routing that causes packet misordering and bandwidth consumption during the process of interdomain handover. In this paper, we propose a new scheme that minimizes the redundant routing during the ...

A new power management scheme enables us to apply the power-gating technique to a 200-Gbps packet forwarding circuit. The circuit is equipped with two 100-Gbps forwarding engines (FEs), each of which processes inbound and outbound packets. When the amount of traffic decreases and only one forwarding engine is capable of processing all incoming packets, a packet-route switch installed in the dat...

This document describes the need of specifying Internet-wide location-aware forwarding protocol solutions that provide packet routing using geographical positions for packet transport.

Applications using transaction oriented communication have special requirements. Packet forwarding of a client’s request and a server’s response should be as fast as possible and also highly reliable. This implies employment of a communication service supplying minimal end-toend delay and minimal packet loss. Currently defined per-hop forwarding behaviors (PHBs) and per-domain behaviors (PDBs) ...

In this paper we describe an XML-based platform for dynamic active node policy updates. XML supports the definition of specific policy languages, their extension to satisfy new needs and the management of deployed policies on different active nodes. We show an example of the management of router packet forwarding policies where the XML policies that drive the packet routing are updated at run-t...

The global Internet is comprised of a large number of autonomous networks that agree to cooperate. Each such network---called an Autonomous System, or AS---is entirely responsible for management and routing of all internet traffic within its own domain. The global Internet works though because ASes enter into business agreements to route traffic from one to another if traffic sources and destin...

The last decade has seen a deluge of proposals for supporting multicast in the Internet. These proposals can be categorized as either infrastructure-based, with the multicast functionality provided by specialized network nodes, or host-based, with the multicast functionality provided by the members of the multicast group itself. In this paper, we present the design and evaluation of a hybrid mu...

Network virtualization provides the ability to run concurrent virtual networks over a shared substrate. However, it is challenging to design such a platform to host multiple heterogeneous and often highly customized virtual networks. Not only minimal interference among different virtual networks is desired, high-speed packet forwarding is also required. This paper presents Europa, a virtual net...

We present an integrated network resource and QoS management framework based on the idea of decoupling the network control plane from the data plane. Our framework is capable of providing perflow QoS guarantees using scalable core-stateless packet forwarding mechanism at the network core. Virtual Time Reference System provides the abstraction of the data plane. Bandwidth broker performs all con...
