Build Encrypted Chat System by using multicast technique with determine delay time

Abstract

Multicast communications and as expected it is an effective way to send information to the largest possible number of receivers. IP multicast has several technical problems to be resolved until it is widely deployed in the Internet. These includes service model of multicast group, reliable transport, security and congestion control. In this paper, we describes the benefits of multicasting and how it can works in local area Network that connected via any server, the Class D addressing from 244.0.0.0 to 239.255.255.255 reserved for internet multicast communication to make connection between many host in the network. A prototype Multicast Chat System (MCS) has been developed to test the capability and suitability of multicasting. The prototype was developed using the Java language. The benefit for this prototype is multi diverse users can be connected without necessary needs for an Internet or Web-server, and thispaper describes the overall work for IP multicast for advantage and disadvantage based on chatting process and simple security algorithm
