This paper discusses the new architecture and protocol of Optical-Label switching in light of its interworking with MPLS and MPLambdaS networks. The dynamic and agile characteristics of Optical-Label switching indicate its support of diverse QoS, CoS, and ToS services while interoperating packet and circuit switching. Optical-Label switching routers employ time, space, and wavelength domain swi...

This paper presents a novel Bayesian method to track multiple targets in an image sequence without explicit detection. Our method is formulated based on finite set representation of the multi-target state and the recently developed multi-Bernoulli filter. Experimental results on sport player and cell tracking studies show that our method can automatically track numerous targets, and it outperfo...

This document describes a historical method for encapsulating Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH) Path signals for transport across packet-switched networks (PSNs). The PSNs explicitly supported by this document include MPLS and IP. Note that RFC 4842 describes the standards-track protocol for this functionality, and new implementations must use RFC 4842 rather...

This document describes an Ethernet-Tree (E-Tree) solution framework for supporting the Metro Ethernet Forum (MEF) E-Tree service over a Multiprotocol Label Switching (MPLS) network. The objective is to provide a simple and effective approach to emulate E-Tree services in addition to Ethernet LAN (E-LAN) services on an existing MPLS network. (IETF). It represents the consensus of the IETF commu...

This document defines a method for the support of GMPLS asymmetric bandwidth bidirectional Label Switched Paths (LSPs). The approach presented is applicable to any switching technology and builds on the original Resource Reservation Protocol (RSVP) model for the transport of traffic-related parameters. This document moves the experiment documented in RFC 5467 to the standards track and obsolete...

This paper aims to study the dynamic QoS renegotiation in a particular case, a videoconferencing application: PNSVS (Petri Net Synchronized Videoconferencing System). In the paper, we present rst the QoS model (TSPN), the architecture and mechanisms used to achieve this QoS. Then we study how to handle with a synchronized switching of QoS. This leads us to a switching framework (an architecture...

The growth of Multi-Protocol Label Switching (MPLS) as the emerging choice for provisioning and managing core networks has placed significant emphasis on MPLS based recovery mechanisms. The present global protection frameworks require extensive involvement of Label Switching Routers (LSRs) in the protection framework. The LSRs are involved in failure propagation and maintenance of information r...

The path recovery in MPLS is the technique to reroute traffic around a failure or congestion in a LSP. Currently, there are two kinds of model for path recovery: rerouting and protection switching. The existing schemes based on rerouting model have the disadvantage of more difficulty in handling node failures or concurrent node faults. Similarly, the existing schemes based on protection switchi...

Switching costs are prevalent in network industries, and this paper investigates their effects on market outcome. I find that the role of switching costs depends on network effects and the outside option. Without a viable outside option, high switching costs can neutralize the tendency towards market dominance associated with network effects, but with a viable outside option, switching costs fa...

This paper discusses optical-label switching and an experimental demonstration of high-speed all-optical packet switching with all-optical label-swapping capabilities. The subcarrier optical-label content was optically extracted and compared against the forwarding table, which induced packet forwarding as well as label-swapping decisions. The alloptical label processing technique was immune fro...
