Abstract
Peer-to-peer (p2p) is a network where anyone or any peer can communicate
at anytime. A peer may be regarded as either client and / or server. Users use this
network for many purposes such as video streaming. This area faces many challenges
such as, network load, network bottleneck, file transfer time, load balancing of files
on servers and response time to retrieve a query. The objectives of this research are
to solve these problems using an effective method. Our contribution involves
combining multicast and unicast techniques and using distributed hash table (DHT)
to store and retrieve a query of media file. The architectural framework is divided
into two parts. The first part involves streaming the video via a multicast address
when the file is available in the local network. The second part involves streaming
the video via a unicast address when the file is available in another network and
using a multicast address when the file is to be transmitted to the local network.
The results show that the proposed method is better than using only the
unicast technique based on the reduction of number of packets on the networks,
reduction of number of dropped packets, reduction of transfer time, and redistributed
files on servers. In the case of six clients, the numbers of packets are reduced by
83.1 % than using unicast only. The response time for retrieving the query result was
very small and follow linear equation y = 0.0017x - 0.0009. So the response time for
retrieving the query result has been improved.
