Abstract

The development of wireless technology has created a new network, namely the MANET network. In a MANET network, a node can be a router or an end user because in a MANET network the node is flexible. MANET networks have proactive OLSR and BATMAN protocols. When a node becomes a router, many other nodes will pass it. This research was conducted to determine the formation of the router node in the middle, namely the router that is passed by a lot of communication and the edge, that is, the router that has little communication through the network using parameters of CPU usage, RAM usage, and processing delay. From the test results, the CPU value on OLSR and BATMAN for the middle router node is 0.3 and for the edge router it is 0.2 when communicating, when there is no communication the CPU value on OLSR is still 0.3 while in BATMAN the BATMAN value drops to 0.2. For memory used in both protocols get 0.0 because the router only forwards packets without needing to process the packet. For processing delay in the two protocols, the value varies because packet delivery has an uncertain delivery interval between packets. In BATMAN protocol, CPU usage is better than OLSR because if there is no data communication, the CPU value from BATMAN goes down and on OLSR there is no fixed CPU value communication.

Abstract

A Server is a system that provides certain services on a computer network. The Server has its own operating system called the network operating system. The Server also controls all access to existing networks.  In order to help server tasks, a server mirroring system is set up where the server is duplicating a data sets or an exact clone of a server providing various information. Mirror server or also called Server synchronization is a duplicate of a server. To add performance from the server, a load balancer is required. Load balancing is a technique for distributing two internet connection paths equally. With the application of load balancing the traffic will run more optimally, maximizing throughput, and avoiding overload on the connection path. Iptables is used for IP filtering so the clients could access the server according to the closest server zone, so that the load balance combined with iptables can reduce the server's load. A common problem is when many clients access a server and the server will overload and cause the server performance to be slow because of the heavy traffic. The access Client also get the effect of this, which is slow response time. From the result of research on the combination of load balance and iptables, it was found that the load balance with the round robin algorithm the average delay obtained for server1 was 0.149 seconds and 0.19122. Server2 has an average delay of 0.161 seconds and 0.012 seconds.
