As broadband services have become more widespread in recent years due to a variety of government initiatives and the establishment of Wireless Internet Service Providers, user requirements have evolved and the market has become more competitive. Whilst this is beneficial for consumers it means that Internet Service Providers must offer a more diverse range of services coupled with standard broadband packages to distinguish themselves from their competitors, generate new revenue and strengthen their competitive advantage. Therefore many providers are looking to Service Oriented Architectures (SOAs) to provide communication platforms, enabling services such as Voice over IP (VoIP) along with other multimedia communications to be easily integrated, deployed and managed in a controlled environment within their core networks. However these platforms are cost prohibitive for small to medium size operators and as lightweight solutions are not prevalent, SOAs are typically only viable for larger telecommunications incumbents.
Hence the contribution of this thesis is a service oriented communication platform for heterogeneous Voice over IP networks. It provides a lightweight VoIP communication infrastructure, as well as configurable telephony services and management functionality and is easily extendable for additional multimedia services. This thesis also presents a QoS measurement scheme that allows service providers to estimate VoIP QoS conditions across best effort IP networks, thus enabling them to validate customer service level agreements and evaluate if measures are required to implement a QoS architecture for real-time services such as voice, in their core IP networks.
