Abstract

Web servers are now an essential part of both developing and newly started companies. Apache is the web application server with the most revenue in the world. Apache, however, has some drawbacks, one of which is that Apache is become slower when serving many requests continuously. One way to improve the performance of Apache web servers is by reverse proxy cahing. Of the many reverese proxy caching, Nginx and Varnish have the highest reputation. To find out the resource management and quality of service revese proxy caching Nginx and Varnish on the Apache web server will be tested by sending a number of requests to the web server. As a result, both servers with reverse proxy caching can outperform the Apache web server without reverse proxy caching on CPU usage and latency in the first 3 tests, whereas on Apache server load testing without reverse proxy caching it provides smaller latecy than Apache servers without revese Proxy cacahing. The comparison between Varnish reverse proxy caching and Nginx paired on the Apache web server, giving the Apache server results with reverse proxy caching Varnish performs better than the Apache server with Nginx reverse proxy caching.

Abstract

One of the problems in computer network is load balancing. The emergence of Software Defined Network (SDN) architecture is expected to be a new paradigm in addressing issues related to load balancing on traditional networks. The flexibility gained from separation between control plane and data plane on the SDN architecture makes it feasible to develop technologies that hard to implement on traditional networks. In this research, a load balancing algorithm is developed based on the SDN architechture. An SDN controller that is connected to an SDN switch will sends messages to each server based on the specified time interval to get the CPU and memory utilization and response time from each server. Those parameters are used to determine the load of each server. The SDN switch will then split request from client to server with smallest load. Load balancing algorithm's performance will then be compared to similar algorithms on server clusters with same specification (homogeneous) and server clusters with different specifications (heterogeneous). The result found that the proposed algorithm is able to distribute requests from clients to servers based on status of the server and perform better than similar algorithms on server clusters with different spesifications (heterogeneous).

Abstract

Push notification technology allows users (clients) to get information periodically. Information submitted by push notification in the form of notifications such as on social network or news sites. There are many technologies that can be applied to notification delivery. One of them is notification delivery using Websocket protocol and Server-Sent Events (SSE). The Websocket protocol implements full-duplex communication so that either the server or client can send and receive data simultaneously. While the SSE protocol implements half-duplex communication so that the client can only receive data sent server periodically. This study was conducted to compare the performance of Websocket protocol with SSE related to method of delivery of both protocols on push notification technology. Both protocols will be implemented and tested based on predetermined scenarios. The results obtained are the average delay and CPU usage in SSE protocol is smaller than Websocket protocol.

Abstract

The Internet becomes an important need in society. The problem that is often faced by the public to access the internet is a slow connection and unstable internet service provider. Multiconnection is one solution that can be used to make access to the Internet network for better. Multiconnnection requires a technique called load balancing and failover. It is used to maximize throughput so that access to the internet becomes more stable and faster. Implementing load balancing and failover requires routerOS to be able to control incoming packets. RouterOS that features load balancing and failover are Mikrotik and Zeroshell. In this study will apply and compare the performance of load balancing and failover that is applied to router Mikrotik and Zeroshell. The load balancing method used in Mikrotik is nth and in Zeroshell uses round-robin method. Based on the results of the study concluded both routerOS can run very well with load balancing and failover. The result of load balancing performance applied to MikroTik using nth method has higher throughput value compared to the throughput value applied to Zeroshell load balancing. Performance results on failover tests applied to Mikrotik have a smaller delay value compared to the failover test applied to Zeroshell.

Abstract

Internet has become the most widely used as media presentations and information exchange. The information exchange can be accessed by using adequate connectivity. Some places still have low connectivity and some place do not have connectivity like Semeru mountain climbing areas, because of that the exchange of information will be difficult to access due to high delay and loss rate. The problem can be solved with Delay Tolerant Network (DTN). DTN is a network concept that is tolerant of delay and disconnected connections on a network. In this study using DTN network simulation process on The ONE simulator to compare the performance of DTN routing protocol with the addition of Stationary Relay Node. Routing types used are routing First Contact, Epidemic, MaxProp, ProPHET, and Spray and Wait with Semeru climbing scenarios. The results of this research show that the highest delivery probability is 0,5388 with 200 node and 15 Stationary Relay Node by Spray and Wait routing. The highest overhead ratio is 6.7484 with 50 nodes and 20 stationary relay nodes by Spray and routing. Routing First Contact before and after the addition of Stationary Relay Node has a higher average latency rate. The lowest average latency is 7491,9710 with 200 nodes and 15 Stationary Relay Nodes by MaxProp routing.

Abstract

Network model architecture that used nowadays are difficult to apply a new protocol because it depends upon vendor, so it appeared a concept that manage network systemperformance through software named Software Defined Network. SDN separating data-plane and control-plane in network devices such as router and switch, so that programming network devices may be done centrally through a controller.A controller manage forwarding table switch which forwarding the flow of communication package.If a controller goes offlinea switch not be able to forwarding the flow of communication package from a device to other devices. So it needs high availabillity controller mechanism to be able to maintain the availability of a controller so the communication package can be arrive. High availability controller can be done by mechanism failover use Heartbeat and DRBD.Testing in this research done with planned downtime methods. The test results that obtained from the average downtime of POX controller when failover process is 23 seconds, and 59,6 seconds when failback process, while Opendaylight controller took time 195 seconds for failover process and 219 seconds for faillback. This method is a good enough, where the more features run in a controller the longer time downtime will produced.

Abstract

Software Defined Networking is a new paradigm that emerging in networking industry to solve today's computer network problem such as the difficult configuration because it used low-level configuration as well as limited visual devices. By using the SDN network, the network will have advantages such as easy to developing and experimenting of new protocols, easy to manage, and ease the network to adapt when there is infrastructure changes. Controller is an important part of the SDN network, because the controller has function to control the login in SDN network. ONOS is a controller that offers the advantage delivering high-availablity, scalable, and bring performace as good as carrier grade class. Dijkstra's shortest path algorithm is one of the routing algorithms. Dijkstra's shortest path routing performance on SDN network using ONOS controller produces lantecy time 0,092 ms using geoDistance function and latency time 0,097 using linkMetric function. This concluded latency time will increase along with the lenght the path used for communicate between hosts. Meanwhile the performance test result of ONOS controller while running Dijkstra algorithm as well as responding to fail path on the network link resulted that ONOS controller provide good performance on the network that requires infrastructure with combination of 20 switches and 40 hosts, and the average convergence time that ONOS needed to build new path is 1,405s.
