Optical layer capacity and unit cost improvements are basic to the rapid growth of Internet
protocol (IP) networks. However, the new rapid reconfiguration and restoration capabilities …

A new IP optical network architecture called multilayer service network architecture that is
intended to reduce network cost drastically and to introduce IP optical technologies easily …

The optical layer can provide its IP clients with rapid and efficient restoration for link failures;
however, its inability to protect against router failures erodes its attractiveness. Here, we …

This paper describes work performed for the Defense Advanced Research Projects Agency
CORONET-funded Protocols and Architectures for Resilient Agile Global Optical Networks …

Recently, Internet service providers (ISPs) have gained increased flexibility in how they
configure their in-ground optical fiber into an IP network. This greater control has been made …

Abstract Large Internet Service Providers (ISPs) are in the process of upgrading their links
from lower rates,(eg, 45 Mb/s to 620 Mb/s) to above 2.5 Gb/s. The lower speed links are …

The Internet transport infrastructure is moving towards a model of high-speed routers
interconnected by optical core networks. The architectural choices for the interaction …

The rapid growth of traffic on the Internet is posing new challenges for transport network
providers. Not only do they need low-cost solutions that increase the capacity of their …

In IP-over-WDM networks, wavelength circuits are often protected by dedicated backup
circuits. Especially with future deployment of 100 G transmission systems, this will induce …

We consider the realization of traffic-oblivious routing in IP-over-optical networks where
routers are interconnected over a switched optical backbone. The traffic-oblivious routing we …
