This paper mainly focuses on the real time based voice chat tool for a real time based company, so I will discuss designing process of voice chat tool.

3.1 Background
Most of voice chat support files transfers in integrated environment. While servers are involve in the initial establishment of the voice call, many communication processes are often done between end users (clients) directly in a point to point (peer to Peer). While if user is offline then Voice message buffered to server and delivered when those users come online. [15].

4. Objectives 目的

The objective of this study is to study and design ‘(Implementation will be submitted with final Dissertation project)’ a ‘voice chat’ API for a real time based “Social Enterprise Charity Company, Network2012”, located at ‘1 Greek Road, W1D 4NQ, London’. The idea of the Project is to study and design use cases, flow charts, sequence diagrams, class diagrams and charts related to this web application tool. This paper discusses the buddy –list model of the internet voice chat [3, 4].

There are so many web application voice chat tools, Instant messaging tool and voice messaging tools made by software developers with their comparative analysis. They also analyse the main functioning of the application/ software depending upon requirements and configuration of the tool. Although these papers show mostly main functioning of the application, it does not detail the ‘voice chat’ architecture, and main obstacle.

Configuring Cisco Voice Over IP [Syngress 2002], [10], represent the basic model of the voice functioning over IP with internal architecture of the internet working and about the architecture of the web click on call function with softphone configuration.

Voice Over Internet Protocol Architecture and features [lulu.com], [11], details the architecture of the various protocols and functioning of the protocols and feature of the voice functioning with the protocol. It explains the H.323 protocols and collaboration with different protocols.

While working with VOIP , we should have to consider about IP functions and appropriate Internet protocol which have to use and have to consider for IP interlinks , from last scenario , it being seen most of professional uses UDP protocol for voice transferring ,[12] tells about the basic UDP protocol.

EVVCM [Dec 2008], [13], shows, VOIP (voice chat) is vulnerable to network congestion if too many users access the web services based IP at the same time. VOIP signalling is usually implemented on UDP.Since UDP can’t verify the packet arrival, so that some there is problem of packet lost or delay in 本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
