| Abstract | There is a problem that the Internet is becoming more crowded with data traffics. Many collaboration tools need to find a way to make use of the communication link as efficient as possible, like whiteboard communication. Nowadays whiteboard programs run on top of Unicast, a one-to-one communication, and Multicast, a one-to-many (and many-to-many) communication with overhead on the routing process, where Multicast has to maintain the states of the communication. An approach to overcome these problems on Unicast and Multicast whiteboards is to deploy a new network protocol on the whiteboards. XCAST is a network protocol intended for a small group of one-to-many (and many-to-many environment) communication with less routing overhead compared to Multicast, it does not have to maintain connection states, but only to follow the existing routing tables from the existing Unicast routing protocols. The idea of XCAST is to inject multiple destination addresses per packet and allows XCAST based routers to parse those destinations to the existing routing tables. The XCAST6 (XCAST over IPv6) whiteboard is developed on this research. The evaluation result shows that XCAST has better transmission response time than Multicast in a small group environment with less than 20 users. For a group of 8 the XCAST improves 10% better response time than Multicast; and an XCAST group of 16 improves 5%. Even though XCAST takes more bandwidth than Multicast, the loads of intermediate routers arc less, and XCAST performs very well in small groups. XCAST is easier to deploy because it is based on the traditional Internet protocol. XCAST communication relies on existing routing protocols and therefore still allows regular IP packets to flow through. This XCAST whiteboard is useful for a small group communication of IPv6 whiteboard without any preparation of Multicast routing in between the group participants, therefore it is easier to deploy in any existing networks. |
