In order to meet their stringent dependability requirements, most modern packet-switched
communication networks support fast-recovery mechanisms in the data plane. While …

Abstract Systems, methods, and non-transitory computer-readable storage media for
forwarding tables for virtual networking devices. The system first identifies local virtual …

This paper investigates the prospects and challenges of hierarchical optical path networks.
The merits and issues of introducing higher order optical paths are elucidated. State of the …

This paper investigates the problem of dynamic survivable lightpath provisioning in optical
mesh networks employing wavelength-division multiplexing (WDM). In particular, we focus …

It is expected that multiprotocol label switching (MPLS) based recovery could become a
viable option for obtaining faster restoration than layer 3 rerouting. To deliver reliable …

The continuously increasing complexity of communication networks and the increasing
diversity and unpredictability of traffic demand has led to a consensus view that the …

Network resiliency is crucial to IP network operations. Existing techniques to recover from
one or a series of failures do not offer performance predictability and may cause serious …

In accordance with one embodiment, a source leaf device receives a packet. The source leaf
device identifies a flowlet associated with the packet and a destination leaf device to which …

Aspects of the subject technology relate to solutions for transporting network traflic over an
overlay network. A first tunnel endpoint in an overlay network can receive an encapsulated …

We investigate the survivable traffic-grooming problem for optical mesh networks employing
wavelength-division multiplexing (WDM). In the dynamic provisioning context, a typical …
