Parallel Multichannel Communications

Abstract

Multi Chat Server also introduces new Jabber protocol extensions to allow video conferencing over RTMP, or moderated / censored chat rooms for example. The according graphical user interface is exposed by the Multi Chat Flash-Client, to offer platform independent web integration. The Architecture-Overview slide shows the parts and services belonging to the Multi Chat Server solution. Basically, it consists of the Multi Chat Server core, the Admin-Interface, a separate web server for configuration settings and the Multi Chat database engine. For personal chat, the server receives messages from a client and based on the target user; it forwards the requests.But in a group chat, there are multiple users. In that case, we need to have a group id instead of a list of users. So, to avoid confusion, we used group id for personal chat. Personal chat is a group chat with one user. The server maintains all the open connections (both personal and group chats)through group id. Whenever a request comes to send the message to a particular group id, it looks up in its list, gets the users, and sends to all the users for that id. Multichannel data communication system in which the stop-and-wait automatic-repeat request protocol for parallel channels with an in-sequence delivery guarantee is used for error control. Packet transmission over a single channel, in a multichannel communication system, multiple packets are sent at a time, one packet per channel, and packet transmission errors can occur across every channel. To implement error control through retransmission of packets in a multichannel communication system. In a wireless communication system, however, the transmission condition of a wireless channel changes over time, and consequently, the channel is often severely affected by time-varying losses. In future work, we can apply the modeling and analytical approach presented in this paper to conduct performance studies on the selective-repeat ARQ protocol over parallel channels with time-varying channel models.
