An interoperable signaling solution between SIP and H.323
(Telkom, 2001)The Session Initiation Protocol and H.323 dominate the Voice over IP world. These signaling protocols are responsible for call setup and call tear down by IP telephony solutions. This project analyses and discusses the ... -
Guaranteed delivery of semi-synchronous IP-based communication
(Telkom, 2004)This research aims to find an empirical solution for guaranteeing the delivery of synchronous and asynchronous messages within a semi-synchronous IP-based communication domain. The communication infrastructure that is ... -
Instant messaging on handhelds: an affective gesture approach
(SAICSIT in association with ACM, 2005)Text communication can be perceived as lacking in chat spontaneity, or plastic, due to medium limitations during interaction. A form of text messaging, Instant Messaging (IM), is now on the uptake, even on mobile handhelds. ... -
An Internet paradigm approach to policy-based network management of legacy kit for VoIP services in Next Generation Networks
(Telkom, 2000)With QoS available on IP-dominant NGNs, Policy-based Network Management (PBNM) is an effective mechanism for managing services as opposed to actual devices. IP is ubiquitous, and any NGN must contend with legacy devices ... -
Grafting an ATM network onto an existing ethernet network
(Telkom, 1998)Grafting an ATM network onto an existing Ethernet network is a non-trivial exercise in network configuration. The process of mating ATM technology to an Ethernet network without tampering the underlying backbone and network ... -
Preparation of Deaf end-users and the softbridge for semi-automated relay trials
(Telkom, 2004)Following on the development of several prototypes, we have built a semi-automated Deaf Telephony prototype on the SoftBridge platform. This prototype relays text and speech between Deaf users on the Internet and hearing ... -
An IP based multimodal semi-synchronous rural telehealth service: Adding video messaging and conferencing to MuTI
(Telkom, 2004)We intend adding video messaging and conferencing to Multimodal Telemedicine Intecommunicator (MuTI), a previous system that has already been in place in the target environment. This is to allow a semi-synchronous communication ... -
An Interoperable signaling solution for IP-based Next Generation Networks
(Telkom, 2000)Current VoIP signaling protocols are interoperable with the PSTN SS7 via H.323-to-SS7 or SIP-to-SS7 gateways. As we move toward the Next Generation Network, the PSTN falls away and we work toward carrier-grade VoIP ... -
FHMIPv6-based handover for wireless mesh networks
(Telkom, 2012)This paper shows that mobility management protocols for infrastructure Internet may be used in a wireless mesh network environment. Mesh topology tends to be an unplanned graph and routes change dynamically and in this ...
