Module Indicative Content
The mathematical models for building numerous types of network, including voice, audio, data, video, multimedia services and Internet Protocol (IP) telephony. Comparative analysis of the different models¿ efficiency for self-similar and non-self-similar traffic.
Speech coding techniques (CODECs)

Open Systems Interconnection (OSI) 7 layer model and the Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) / Internet Protocol (IP) stack including real-time protocol (RTP) and Resource reSerVation Protocol (RSVP), IPv4-v6 migration issues. ATM and MPLS.

Definition of Quality of Service (QoS), queuing techniques including congestion avoidance techniques and signalling requirements including H.323 Session Initiation Protocol (SIP) and Media Gateway Control Protocol (MGCP). Voice and data quality factors including echo, delay and acceptance.

Network Dimensioning: Simple compressed voice flow model, components of a network dedicated to IP telephony, merging voice and data communications on a common IP backbone.
Multipoint communications including audio multipoint conferences and multipoint video conferencing. Call Seizures.


Services available to IP phones compared to that of a PSTN, Transferring information over the whole network i.e. Skype. Teleconferencing ¿ transfer video streams (Teleprescence).The application of Voice over IP within a commercial environment VLANs.
