Vehicle routing problem

COURSE TITLE: CN8810 SUBMISSION DATE: October 14, 2015 QUESTION What are Routing Loops? The following techniques are used to prevent routing loops: 1. Split Horizon 2. Route poisoning 3. Hold-down timer Explain two of the above techniques briefly with diagrams. SOLUTION ROUTING LOOPS Routing loops occur as a result of inconsistent routing table. When using distance-vector routing, routers can learn “bad” routes and send them to other routers thereby forming a…

A routing loop is a situation that occurs between two or more routers in which a packet is continuously routed between the routers as a result of irregularities from the routing algorithms and/or the routing tables of the routers. (routing loops, 2015). An example is when three routers are connected in a triangular pattern i.e. router A is connected to router B, router B is connected to router C and router C is connected to router A, when the network is converged, all three routers will have…

In this section the fast-recovery algorithm that makes TCP NewReno[1] perform better than the Reno[3], is described. During congestion avoidance if the sender receives triple duplicate ACKs, then it performs fast-retransmission and enters into fast-recovery. In fast-retransmit the sender retransmits the lost segment,sets the threshold value for slow-start as ssthresh = cwnd/2, and sets congestion window, cwnd = ssthresh+3 segments. In fast-recovery, the sender increases its congestion window by…

attackers apparently eliminate their presence in the network and make such attacks difficult to detect. The goal of such an attack is to violate the confidentiality of the communications by intercepting the network and sniffing or listening to the routing packets. Also, an adversary can actively influence the communication channel by disrupting, jamming or modifying the network packets and/or inserting false packets into the network. Jamming happens at physical layer which can cause intermission…

Answer 3:- A:- When it is very expensive and slow to access the external network then we use Forwarding name server . What is does keep the records of frequently visited sites in local DNS cache. This improves the efficiency . B:- Round Robin mechanism is used for load balancing . DNS hold maximum record of entry. In round and robin mechanism it allocate IP address to the requested client as per the availability and making the server highly available . Answer 4:- "in.addr-arpa" is used to…

The dark net and all its secret Drugs, human trafficking, and cyberwarfare, these are the thing that can be found on the dark net. The dark net gives us access to all of the content that is not available to us through the normal means. It was developed in the 1990s by the U.S Navy, it is an encrypted web search that allows anyone to search anything in the comfort of their own home without the fear of being found by the authorities. The dark net has many search engines that is well protected,…

The same can be said for the engineering of motor vehicles. From the simple A to B cars that last forever to land-speed record breaking rocket cars. Trying to limit vehicle engineering is like trying to limit the most basic of human abilities. The only thing that comes from restriction is further innovation. Todd Griffith from blog.cargurus quotes a few car manufactures…

the water intrusion. All areas around the window were found to be dry and in original condition with no sign of intrusion in the outer wall. A couple of photos are included. The contractor believes condensation on the window was the cause of the problem as there was no sign of water intrusion. His inspection confirms that of your inspection report. The Point Meadows Place Declaration Section 7.1 (b)(1) clearly places responsibility for window and…

Observations made were that the high costs and inconsistencies in the plastics quality are the main problems for Superior Filament. Seeing this shows that Superior Filament needs to find a way to obtain these plastics themselves, but it has to have an efficient cost. One idea is for Superior Filament to set up donation bins around grocery stores and the…
