A Study on Quality of Services in Unified Communication Networks Using Cloud Computing Methodology

Abstract

Unified Communication (UC) networks in the enterprises for data transmission whereas an analysis of the real-time and non-real-time usage of services required for Enterprise oriented Unified Communication networking with enhanced QoS is done and as a measure the usage of Cloud storage is suggested for enhancing the QoS to meet the requirement of the end users. UC consists of group products that produces unified interfaces and also understand over several devices. However, the UC infrastructure present in enterprises may need agile, resilient, ease and secured characteristics have been changed as per dynamic requirement whereas the services of unified are implemented by the major components namely call routing server, media gateway, registrar, session as border controller, bridge for video conference, application tools of collaboration etc. In implementing UC, there are various challenges get faced has become a main factor that need to be consider is network speed in order to avoid latency which straightway impact the complete enterprises network communication. Hence, the management and maintenance of the data flow in and out of the expanding Enterprises will be the challenging task. Priority is also considered for Video calls compared to Voice calls when they are made from same source and possibly to same destination. Also, the metrics related to the free part of the queue buffer of each port together with the packet size and bandwidth is to be measured and stored along with the jitter and packet loss. This may assist to find the correlation between bandwidth of high priority with 50%, medium priority bandwidth of 35% and least bandwidth priority of 15% as concept. This concept gets accomplished using knowledge-based networking that reallocating the required packets based on the priority. The throughput is better in 50% of high priory bandwidth.
