 As a IP telephony protocol, the SIP is gaining increasing popularity. There is yet POTS(Plain Old Telephone Service) line as the existing subscriber line. The Megaco/H.248 may be used for call between the POTS line and SIP. So, it is needed that method for interworking between Megaco/H.248 and SIP. In this paper, we propose the implementation of Residential Media Gateway Prototype in Interwor...

The ever increasing quantity of newly discovered computer security holes makes many network-based service including especially Voice over IP (VoIP) system vulnerable, hence impose a heavy impact on business development. Megaco or H.248 is a recent emerging VoIP protocol which will promote carriers to move into VoIP applications. In this paper, we present the vulnerability testing of Megaco prot...

The best-known media gateway control protocols are currently Media Gateway Control Protocol (MGCP) and Megaco/H.248. MGCP, described as informational RFC 2705, has been widely deployed. Megaco/H.248 has evolved from MGCP. It is a single unified protocol that resulted from the cooperation between the Internet Engineering Task Force (IETF) and the International Telecommunication Union (ITU). Mega...

This paper analyzes performance of MEGACO (Media Gateway Control Protocol) based on Diameter which is an Authentication, Authorization,andAccounting (AAA) protocol developed within the Internet Engineering Task Force(IETF).Diameter is loosely based on Remote Authentication Dial In User Service (RADIUS), which has previously been used to provide AAA services for dial-up and terminal server acces...

This document is being published for the information of the community. It describes a non-IETF protocol that is currently being deployed in a number of products. Implementers should be aware of RFC 3525 [37], which was developed in the IETF Megaco Working Group and the ITU-T SG16, and is considered by the IETF and ITU-T to be the standards-based (including reviewed security considerations) way ...

This paper presents the architecture and design of an enhanced VoIP gateway, which is based on the H.323 protocol. The key characteristics of this gateway include: scalability separating signaling from media transformation and use of protocols such as MGCP/MEGACO for the communication between signaling part and media gateway; lightweight by using SCTP transport protocol to convey H.323 and MGCP...

in this paper, analysis and simulation of media gateway controller (megaco) based cops (common open policy server) which is a protocol defined in ietf (internet engineering task force) to transport configuration requests and deliver the policies is presented. for this scenario, three queuing models include m/m/1, m/m/c and m/d/c were applied . then, some of the key performance benchmarks look l...

Gegenstand der hier vorgestellten Bachelorarbeit ist die Erstellung eines Realisierungskonzepts und der Implementation des Kommunikation-GatewayProtokolls MEGACO auf einer spezialisierten (embedded) TelekommunikationHardware-Plattform. Die angestrebte Anwendung ist die Verbindung von klassischen Telefonnetzen mit der Internet-Telefonie.
