The Megaco protocol is used between elements of a physically decomposed multimedia gateway and is the result of cooperative efforts of the IETF and the ITU-T Study Group 16. The protocol definition of this protocol is common text with ITU-T Recommendation H.248. There are no functional differences from a system view between a decomposed gateway, with distributed sub-components potentially on more than one physical device, and a monolithic gateway such as described in H.246 . The Packet network interfaces may include IP, ATM or possibly ot ....etc

Abstract

Auctions are among the Latest economic institutions in place. They have been used since antiquity to sell a wide variety of goods, and their basic form has remained unchanged. In this dissertation, we explore the efficiency of common auctions when values are interdependent- the value to a particular bidder may depend on information available only to others-and asymmetric. In this setting, it is well known that sealed-bid auctions do not achieve efficient allocations in general since they do not allow the information held by d ....etc

Media Gateway Control Protocol (MGCP)

This protocol controls telephony gateways from external call control elements called media gateway controllers or call agents. Converting among the audio signals carried on telephone circuits and data packets carried over the Internet or over other packet networks is done by telephony gateway. According to the call control architecture assumption of the MGCP the call control intelligence is outside the gateways and handled by external call control elements and these call control elements, or Call Agents ....etc

ABSTRACT
While magnetic and semi-conductor based information storage devices have been in use since the middle 1950â„¢s, todayâ„¢s computers and volumes of information require increasingly more efficient and faster methods of storing data. Among the most promising of the new alternatives are photopolymer-based devices, holographic optical memory storage devices, and protein-based optical memory storage using rhodopsin , photosynthetic reaction centers. This paper focuses mainly on protein-based optical memory storage using the photosen ....etc

high speed protocol processor to boost gateway performance


Abstract
high-speed protocol processor for gateways based on the concept normal data transfer is executed by special-purpose hardware and a general-purpose microprocessor handles abnormal data transfer and connection control. To analyze the quantitative effect of this proposal, a high-speed protocol processor which can execute OSI (open systems interconnection) layers two to four was manufactured, and its performance was measured. The protocol processing time for normal data trans ....etc
