Future high speed, broadband networks such as BISDN (Broadband Integrated Services Digital Network) support diverse applications like voice, video and data transfer. ATM (Asynchronous Transfer Mode) is considered to be the most promising transfer technology for implementing these networks. This paper presents a scheme, which may be used for the performance evaluation of ATM switching networks w...

A new class of latch controllers for asynchronous pipelines is presented. In addition to the standard operating mode, they can be configured in a collapsed mode, where the pipeline latches they control are kept transparent effectively joining the neighbouring pipeline stages into one. The depth of the resulting pipeline is dynamically adaptable, which can be used for power management of asynchr...

The paper is concerned with the modeling of the electrical signals and of the asynchronous circuits by } 1 , 0 { → R functions and asynchronous automata. The equations of the asynchronous automata are written and solved; the stability, the fundamental mode of operation, the semi-modularity and some aspects of semantics of the propositional temporal logic as seen from behind asynchronous automat...

We introduce a new design style called extended burst-mode. The extended burst-mode design style covers a wide spectrum of sequential circuits ranging from delay-insensitive to synchronous. We can synthesize multiple-input change asynchronous finite state machines, and many circuits that fall in the gray area (hard to classify as synchronous or asynchronous) which are difficult or impossible to...

This paper examines a few techniques for booting Asynchronous Transfer Mode (ATM) switches securely over an insecure network. Each of these techniques assume a diierent trust model. This work is being carried out in the context of the Fairisle ATM switch environment. In this environment we are envisaging an open multi-service network where ATM switches are booted with third party software, poss...

ADIOP is an application for Automated Diagnosis of InterOperability Problems. Interoperability testing involves checking the degree of compatibility between two networking devices that implement the same protocol. In ADIOP, each interoperability test case is first modeled as a Constraint Satisfaction Problem. Object-Oriented Programming is used to implement ADIOP. In this paper, we present the ...

A model for the analysis of multistage switches based on shared bu!er switching for Asynchronous Transfer Mode (ATM) networks is developed, and the results are compared with the simulation. Switches constructed from shared bu!er switches do not su!er from the head of line blocking which is the common problem in simple input bu!ering. The analysis models the state of the entire switch and extend...

One of the major attractive of Asynchronous Transfer Mode (ATM) networks is its ability to exploit the multiplexing gains of packet switching while providing Quality of Service (QoS) guarantees. An ATM based switch can intermix all classes of traffic such as interactive video, graphics, image, and data, on the same transmission and switching fabric, with a guaranteed QoS. This paper proposed a ...

The OSU scheme is a rate-based congestion avoidance scheme for ATM networks using explicit rate indication. This work was one of the rst attempts to de ne explicit rate switch mechanisms and the Resource Management (RM) cell format in Asynchronous Transfer Mode (ATM) networks. The key features of the scheme include explicit rate feedback, congestion avoidance, fair operation while maintaining h...

Layer 2 services (such as Frame Relay, Asynchronous Transfer Mode, and Ethernet) can be "emulated" over an MPLS backbone by encapsulating the Layer 2 Protocol Data Units (PDU) and transmitting them over "pseudowires". It is also possible to use pseudowires to provide low-rate Time Division Multiplexed and a Synchronous Optical NETworking circuit emulation over an MPLS-enabled network. This docu...
