ABSTRACT
We conduct research with testbed experimental at Point to Point topology use wireless 802.11n. We applied Interface Bonding and Channel Bonding to studying the performance that would be achieved when applied both techniques at Point to Point Wireless links.We proposed experiment process and design to measures the performance of this study, several parameters are uses such as delay, jitter, data loss rate and throughput applied on TCP/UDP protocols. We test the performance of both technique with different Packet Sizes and Directional Traffic Flows in Lab Environment. The results showed that Channel Bonding has significant throughput improvement when applied at Point to Point connection used wireless 802.11n. This due to the capability of the Channel Bonding to optimize the available bandwidth of wireless 802.11n, by wider the bandwidth spectrum. However, a different result is obtained for the Interface Bonding that far from expectation, where the throughput is least than single link. This is caused by Media Independent Interface (MII), and Scheduling Algorithm are unable to work properly at wireless 802.11n that use Point to Point connection.
