<![CDATA[Computer network using LAN has limitations in terms of the large number of computers that will be connected to the switch equipment. This limitation can be overcome by connecting the LAN between each other using a router. Networks inter LAN still pose a problem in terms of safety, although the amount can be overcome. To overcome the problem requires a LAN in a small group that is often known as Virtual Local Area Network (VLAN). VLAN can be connected as is often done on the LAN in general with the addition of some equipment that is able to be used as the connecting or known by the name of inter-VLAN. inter-VLAN configuration can be done directly and indirectly. the configuration directly by configuring the network equipment such as switches and routers, while the indirect configuration can be done using packet tracer. In doing inter-VLAN configuration requires a command performed by an administrator. Commands that is configured on the network equipment is a command that is still a command line or a particular script. For people who have not worked as a network administrator needed a software Graphics User Interface (GUI) for ease in studying network administration. Software Graphics User Interface (GUI) can facilitate a person who has worked as an administrator to configure inter-VLAN.]]>

<![CDATA[Development o f information technology and computer networks in particular its services on the one hand facilitate the work of human beings, but as the very widespread use of the internet, the security level of digital data has become more vulnerable to exploitation. The problem arises when the attacks happened on a computer network in a relatively fast, so that an administrator must always keep an eye on the computer network security. Limitations o f an administrator is exactly what underlies thecreation o f a system capable o f detecting and prevention of these attacks, so the time efficiency can be actually implemented. The system is built to prevent attacks on computer networks such as port scanning, ftp, ssh and telnet brute force. This system will analyze the number o f errors that occur on login these services, and makes a decision system if the login error exceeds the tolerance of an administrator. I f the number o f errors exceeds the tolerance, it will automatically create the firewall rules in a very short duration is one minute, so the system is able to prevent the attacks which happened in a very quick time.]]>

<![CDATA[The increasing demand for the utilize services computer networks has increased the traffic on the network. In general, the server provides service round the clock without a break, so that problems such as breakdown of communication in the network is lost that must be avoided. This cases need for a bettersystem with high performance and reliable every time. Current server technology development will be fast but the memory access speed is slower than the increase in the consumption of bandwidth. This is one o f the factors causing the bottleneck experienced of server. With the load balancing can be provide abetter solution. The concept used to provide a server has the same service. Then, the load balancing will check the CPU usage on each server. The server will perform selection based on the value of the smallest CPU Usage o f all existing servers. The application load balancing is placed before the user accessing ofserver with the object of distributing requests from the user to any of the servers that have been selected by the load balancer. Load balancing provides many benefits to systems that use it. The first, low cost, existing resources do not need to be replaced or discarded. Second, don't always need high end equipment. Third, easily developed when needed arose and a drastic decline in the quality o f service. Load balancing is also more secure, when a failure occurs on the server, load balancing application will redirect the user to the server is still available.]]>

<![CDATA[In managing a server, an administrator takes a variety of ways for ensuring the safety and cosiness of the system. One type of threat that attack on the server is done on a port that is in an open state, thus making people who do not have access rights to perform port scanning to infiltrate into the server. One solution to cope with the attack on the port can be done by using port knocking. Port knocking is a method that can be applied to the server with the workings of such a code to unlock the safe. Port knocking is done by inserting a predetermined port sequenced to open a specific port. At the port sequenced delivery process takes an additional authentication likes keyport. Anggi algorithm (AA) is an algorithm that is built by combination o f Diffie-Hellman and RC4. The algorithm is used for encryption and descriptions a keyport from client side to the server side. In the process of sending a keyport to be modified by using the arithmetic calculation. Process of encryption and description keyport is done to prevent some attacks on the server by hackers with extracting such information after successfully breaking into a port. The results o f implementation AA algorithm on the process of port knocking can secure the delivery process o f keyport and improve the security o f server.]]>

<![CDATA[Data communication in the internet today is so complex as an example of the speed factor becomes very important in communicating, everyone wants fast data communication services provided in order to maximum. In relation to the application as a communication liaison with client server applications, web service using a data serialization format to transmit the data. Before the data is sent, either fromthe client to the server or vice versa, should be modified in a specific data format beforehand according to the web service is used. Types of data serialization format used in the web service such as XML and JSON. The method used for testing include data serialization method, data measurement method and data parsing method. Data serialization method is used to calculate the time serialization of data from the database to the form of XML and JSON in applications with PHP platform. Data measurement method used to measure the size of the XML and JSON data which based on many fields of data serialization process. Data parsing method is used to calculate the processing time and JSON parsing XML data. Results o f comparative analysis o f XML and JSON in PHP applications using thearchitecture Rest can be concluded that the test result o f the difference in time and time serialization and JSON parsing XML data is influenced by the number o f records, if the number of records the greater the difference in eating time data serialization and parsing the data the greater the time also itcan be concluded that the faster the process JSON serialization and parsing XML data is compared. Testing results o f the JSON data size is smaller than the size of XML. Data exchange using XML format has a size limit of up to 31456.31 KB while JSON XML exceeds the size limit. Testing results on the Internet when the number o f records up to 50,000 data when the data serialization and parsing time data can not be detected in the database.]]>
