Sky X Gateway and Sky X Client/Servers systems


INTRODUCTION
Satellites are attractive option for carrying internet and other IP traffic to many locations across the globe where terrestrial options are limited or prohibitive. But data networking on satellite is faced with overcoming the large latency and high bit error rate typical of satellite communications as well as the asymmetric bandwidth design of most satellite network .Satellites are ideal for providing internet and privat ....etc

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

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

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
