Generalized Multi-Protocol Label Switching (GMPLS) is a suite of protocol extensions to MPLS to make it generally applicable, to include, for example, control of non packet-based switching, and particularly, optical switching. One consideration is to use GMPLS protocols to upgrade the control plane of optical transport networks. This document illustrates this process by describing those extensi...

There has been significant recent work in increasing the capabilities of Ethernet switches and Ethernet forwarding models. As a consequence, the role of Ethernet is rapidly expanding into "transport networks" that previously were the domain of other technologies such as Synchronous Optical Network (SONET) / Synchronous Digital Hierarchy (SDH), Time-Division Multiplexing (TDM), and Asynchronous ...

We provide machine-independent characterizations of some complexity classes, over an arbitrary structure, in the model of computation proposed by L. Blum, M. Shub and S. Smale. We show that the levels of the polynomial hierarchy correspond to safe recursion with predicative minimization. The levels of the digital polynomial hierarchy correspond to safe recursion with digital predicative minimiz...

It is has been previously demonstrated [4] that Internet topologies which were once considered unstructured networks with no global design processes actually follow powerlaws, both at the router level and the AS (Autonomous System) domain level. This discovery has very wide implications on network research as well as network and protocol design. The Internet is not the only network instance to ...

This paper presents a method of design the counter using sequential system based on synchronous techniques. For the design the counter, first of all, we derive switching algebras and their operations. Also, we obtain the next-state functions, flip-flop excitations and their input functions from the flip-flop. Then, we propose the algorithm which is a method of implementation of the synchronous ...

Synchronous programming languages are well-suited for the implementation and verification of real-time systems. The main benefit for the estimation of real-time constraints is thereby that the macro steps provided by synchronous programs can be directly used for runtime analysis: If synchronous circuits are generated from these descriptions, the macro steps are implemented by combinatorial circ...

Rapid Single Flux Quantum (RSFQ) logic is a digital circuit technology based on superconductors that has emerged as a possible alternative to advanced semiconductor technologies for large scale ultra-high speed, very low power digital applications. Timing of RSFQ circuits at frequencies of tens to hundreds of gigahertz is a challenging and still unresolved problem. Despite the many fundamental ...
