Abstract:
Scalability is an important aspect of communication networks. With the ascent of SIP and associated modern real-time protocols, IP telephony has become a revolutionary technology in connecting users through real-time voice communications with enabled video and instant messaging capabilities. B2BUA is a SIP server that provides call management and authentication functionality by reformulating the request and routing the traffic to other user agents in the network. It comprises signaling and media entities that handle all control signaling messages and real-time data(media) information respectively. The signaling and entities run as different processes in the same container. Such an architecture encounters a large CPU utilization after a specific number of maximum calls due to increase traffic flowing within the same node. Further Packet processing is CPU intensive and there is a need for an architecture that scales well with increasing traffic without hitting the CPU performance. The paper presents the design of decoupled architecture for Signaling and Media entities by running both the processes in different containers. With such an approach, one Signaling entity can communicate with multiple Media entities or vice versa thereby providing a suitable scalable solution to deal with the increased traffic and further maintaining the system efficiency. The paper is concluded by highlighting the difference between Kubernetes and OpenStack for the proposed architecture

Abstract:

This thesis evaluates and shows an implementation of a video telephony solution for network connected set-top boxes based on the SIP protocol for managing sessions.

Unlike other video telephony implementations the set-top box does not handle both audio and video, but only video. A separate phone is used to handle audio. To maintain compatibility with other video telephony implementations, which expect a single SIP device with both audio and video capabilities, a mechanism to merge the audio (SIP-phone) and video (set-top box) into a single entity was developed using a back-to-back user agent.

Due to the set-top boxes'limited hardware it could be impossible to have video compression and decompression performed by the set-top boxes. However, numerous performance tests of compression algorithms showed that the computational power available in the set-top boxes is sufficient to have acceptable frame rate and image quality in a video telephony session. A faster CPU or dedicated hardware for video compression and decompression would however be required in order to compete with dedicated video telephony systems available today.

The implemented video telephony system is based on open standards such as SIP, RTP and H.261, which means interoperability with other video telephony implementations, such as Microsoft's Windows Messenger 4.7, is good.

Successful service relies on learning about customers; i.e, learning about customers’ needs and customers’ expectation. If service providers do not understand their customers, the quality of the service will be diminished, service productivity will fall, and the overall business performance will suffer. More and more companies throughout the world are adding value to their core corporate offerings through services. The trend is pervading almost all industries. It is customer demand-driven and perceived by companies as sharpening their competitive edges, company seeking greater profitability and competitive advantage must balance a customer- and market-oriented focus. This research uses ties strength perspective and through in-depth interview for exploration of customers’ real needs. From in-depth interview, this research find “servitization” is the critical factor when B2B customers make purchase decision. So this research designs a servitization roadmap for win-win cooperation between supplier and buyer. Suppliers should reorganize their service process to reach competitive advantage. The best method is to stage a servitization roadmap. In order to grab competitive advantage of low costs, differentiation and customer bonds, based on real customer needs, this research integrates product differentiation, professional sales, knowledge based technology service and after sales service differentiation as a B2B servitization roadmap.
