Case 10.1.3 Essay

9. Rip Cord: Of an optical cable, a parallel cord of strong yarn that is situated under the jacket(s) of the Cable for the purpose of facilitating Jacket removal preparatory to Splicing or breaking out. (Rip-Cord.html)

In a figure all ways from S to D incorporate hosts that are outside the request zone. Accordingly, there is no surety that a way can be discovered comprising just of the hosts in a picked request zone. In this manner, if a route is not found inside of a suitable timeout period, our convention Wows S to start another route disclosure with an extended request zone – in our simulations, the extended zone incorporates the whole system space. in this case the inactivity in deciding the route to D be longer.

23. The process used by a router to accept a packet on one interface and forward it out another interface.

In this example, we have three routers A, B and C. C’s E0 is directly connected to 192.168.3.0. And C’s routing table is (192.168.3.0; 0; E0) which shows that 192.168.3.0 is 0 hop away. RIP (Routing Information Protocol), running on C, tells B that 192.168.3.0 is reachable through C with a distance of 0. B adds 1 hop to the distance and enters the route to 192.168.3.0 into its own routing table which becomes (192.168.3.0; 1; S1). Now RIP is running on B and tells C that 192.168.3.0 is 1 hop away. Similarly, C adds 1 hop to the distance and enters the route to 192.168.3.0 into its own routing table which becomes (192.168.3.0; 2; S1).

This protocol use Dijkstra algorithm. It maintains a complex data base, also called as link state database, which contains full information about the remote routers and the exact network topology. The goal from this protocol is to provide similar information about network connection to each router, so each router can calculate the best route to each network this is happen when each router generates information about itself and pass these information to other routers in the network so each router make a copy of this information without changing it.

(b) Redirection with modified hop count: This type of attack is targeted against the AODV protocol in which a malicious node can increase the chances that they are included on a newly created route by resetting the hop count field of a RREQ packet to zero. [17]

Being proactive, AODV doesn’t need all its nodes in a network to maintain the routes to destinations rather request a route only when needed i.e., only the nodes which are communicating would require to maintain the route. Also AODV uses sequence numbers to avoid routing loops like in DSDV. Whenever a node needs to communicate with another node, a route has to be found and for that purpose Route Request (RREQ) message is broadcasted to all its neighbors till it reaches the destination node or route to destination. A temporary route table entry in initiated by the RREQ messages throughout the network. Once the destination or a route is found, Route Reply (RREP) message is sent back to source by unicasting along the temporary reverse path of the received RREQ message. RREP message initiates in creating a routing table entries for the destination in intermediate nodes on its way back to source. After certain amount of time these routing table entries expire. Neighbors are detected by periodic HELLO messages (a special RREP message). If a node A does not receive HELLO messages from a neighbor B through which it sends traffic, it assumes that a link is broken and the failure indication is forwarded to its active neighbors. When this message reaches the sources, then either they request a new route by sending new RREQ messages or stop sending data. HELLO messages and the

In simulated network the source node designated as1 initiates the routing procedure by sending RREQ or Route Request message to its surrounding nodes. The RREQ message sent by the source node is denoted in the color green. The other RREQ messages are shown in cyan, yellow, black etc. The source node 1 is sending the RREQ message to its neighbour nodes 5, 6, 9, 11 and 13 and the links are formed shown by the green line. Every time node 5,6,9,11,13 is sending the RREQ message to its neighbour and the links are formed.

1. The route command accepts the wildcard * (such as reoute delete 10*, which deletes all route beginning with the decimall value 10 regardless of the rest of the valur). What are some possible uses of the wildcard value in determining or altering routes?

Rip’s wife was always yelling at him no matter what he did, he could not make her happy. Eventually, he got so tired of hearing it he started shrugging his shoulders as if he wasn’t listening. This shoulder shrugging became a bad habit of Rip’s which on made his wife angrier. She was mostly upset that he wouldn’t do anything. He wouldn’t work on their farm or make sure things were in order, but he would

When the United States was trying to become a country, it was very underestimated by the bigger countries because it was only thirteen colonies and it was considered laughable to other countries. In the story Rip represents the colonies by being very friendly, childish, and naive. For example, when Rip is in the forest about to leave and this strange, nameless man starts calling his name and instead of running the other direction goes up to him and tries to help. “If left to himself, he would have whistled life way, in perfect contentment; but his wife kept continually dining his ears about his idleness, his carelessness, and ruin he was bring on family” Irving 32. He wants to be free from the tyranny of his wife, so he can live freely. The United States wanted to be free from King

In this relationship, Rip escaped from the issues he faced by temporarily leaving his home. While this provided short-term relief, it worsened the problem overall. He was

Rip describes the people as if their very character seemed changed. This shows how time has had an effect on how people act and behave. The people have a

The RIP is a system that is computer generated and helps the doctors make decisions for the patients they are caring for. There are many ways you can look at the RIP system. The RIP system consist of some good ways and some bad ways, everybody can look at it differently. In my eyes the RIP system is a good idea. Let me give you some of the different ways you can look at the RIP system.

Although Irving’s story had striking similarities with the folktale, he fused history of the American Revolution with the old imaginative literature. Irving used the story of Rip to symbolize the struggles Americans faced before and after the Revolutionary War.
