Distributed systems will help us to finish jobs faster by using multiple machines as one machine. This will be done using job scheduling and load balancing between multiple servers or machines. The machine, which request the jobs may, may divide it to multiple chinks, which the load balancer will send every chink to a server to be calculated then send response to the client. Other times, these servers could be used to serve multiple request from multiple users. In the case, the load balancer will divide the requests between servers and send response to the client.
Round robin is a technique for load balancing using the method of divide traffic equally between multiple destinations. This technique will send packet to first available server in the queue then send it to the end of the server queue. In this way, it will guarantee that servers have one or zero difference between numbers of jobs. In this way, the load balancer guarantees equal load between servers but this works will if all servers have the same processing power. Processing power mean the maximum number of processes that a server can handle before it crashes, reboot, or start to drop request. Processing …show more content…
With time Servers processing power will decline every year and new servers will have different processing power than old servers. In this way, old server or servers with less processing power than other server will be overloaded very fast. To overcome this problem a new algorithm introduced will take this factor in mind. Weighted round robin will compute this processing power of every server. The difference between this way and round robin that it will check if the server at top reaches maximum requests number of connections, if not it will send it more requests otherwise it will send it to the end of the queue. In this way, every server will have his processing power

2. Incapabilities. The attackers do not issue strong active attacks such as black hole. They can only perform intrusion to a proportion of all nodes. Their computing resources are not unlimited; thus, both symmetric and public/private key cannot be brutally decrypted within a reasonable time period. Therefore, encrypted data are secure to a certain degree when the key is not known to the attackers[7]. IV NETWORK MODELS We use two different network models, random way point model [7] and group mobility…

Figure 6-6: The information box appearing when a indicator is clicked The path is drawn by starting on sorting the times ascending and giving each entry in the filtered database and giving each entry an iteration number. Starting from the first iteration a marker green marker is added indicating the start of the path. An indicator is added on the map to all of the following entries up to and including the last point showing if the speed was exceeded or not as shown in figure 6-5. A straight line…

2. Multiple path identification i. Neighbour identification When the nodes are deployed in the network, they periodically broadcast the RREQ message to its neighbor nodes. The RREQ message includes the node ID and its location information. The RREQ messages, based on each node identifies itself and also maintains the neighbors list which contains the nodes ID and location of each neighbor node. When source node wants to transmit data packet to destination, a RREQ message is transmitted to destination…

This monitoring includes some method of monitoring bandwidth and port states. Many PLC manufacturers have the ability to respond to SNMP. It is doubtful. A custom / standard MIB would be straightforward. MIB uses for cover the typical network behavior. An engineer would use a network for forensic and diagnostic purposes but it is doubtful that it is use it for data gathering. Data that might have use for both engineering and alarm for PLC time cycle. PLC time cycle depends on what PLC doing. 4.3…

1) A) Broadcast domain is a domain in which (pcs, etc) can communicate via broadcasts, these are set up through switches, as routers block broadcasts. B) Collusion domain: is a domain where info (packets) can collide with one another, as such only one device may communicate at a time. 2) Hubs deal with frames, switches do as well but they also utilize the mac addresses(so they direct what goes to what). Hubs share bandwidth with each available port as it copies each frame to each port (it broadcasts…

1.2.1 Studying Server Consolidation Server consolidation is an approach to the proficient usage of computer server resources in order to decrease the total number of servers or server locations that an organization requires. The practice was developed in response to the problem of “server sprawl,” a position in which multiple under-utilized servers take up more space and consume more resources than can be justified by their workload.
