Multipath routing

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…

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,…

In this project, Vehicle Routing Problem (VRP) is studied. VRP is an NP-hard combinatorial optimization problem. It appears in a large number of real world situations, such as transportation of people and products, delivery services, garbage collection etc. It can be applied everywhere, for vehicles, trains, plains; that is why Vehicle Routing Problem is of great practical importance in real life. The Vehicle Routing Problems (VRPs) are the ones concerning the distribution of goods between…

QUES 1. A router has the following CIDR entries in the routing table: Address/Mask Next Hop 135.46.56.0/22 Interface 0 135.46.60.0/22 Interface 1 192.53.40.0/23 Router 1 Default Router 2 For each of the following IP addresses, what does the router do if a packet with that address arrives? 1. 135.46.63.10 2. 135.46.57.14 3. 135.46.52.2 4. 192.53.40.7 5. 192.53.56.7 g entirely with bytes is much simpler than working with individual bits. Answers: 1. 135.46.63.10 Using the first 22 bits of it as…

1. Goal The primary goal of this lab was to establish a base network in RLES that will be built on in future labs. We worked with new PFSense, a routing interface with which I was unfamiliar. I learned how to configure internal and external interfaces with PFSense, and was able to modify the rest of the necessary settings via the Web GUI. We learned how to configure RHEL, and also got to experiment with setting up a Wiki. Finally, we had a chance to configure and work with a monitoring…

the position to its endpoints is under our threshold. During the selection, a polyline will be selected to match out position. Three criteria are considered: the normal distance, the slope of the line relative with the heading direction, and the routing route. Each factor will be given equal weighting and the line with the highest matching result will be chosen. In the matching phase, the position is simply matched to the normal projection on the polyline if its projection is on the segment or…

The important characteristics of IR is that it can’t penetrate walls or other opaque materials. Typically, with an IR-based system, a receiver is placed in every location in which a tagged device might be found. The tagged device emits IR light, and if the tagged device is in the same room as a receiver its position is known. The major advantage of an IR-based system is that as the oldest and most installed positioning technology, solutions are generally available from a variety of sources…

While ubiquitous Internet access is extremely convenient and enables marvelous new applications for mobile users, it also creates a major security vulnerability—by placing a passive receiver in the vicinity of the wireless transmitter, that receiver can obtain a copy of every packet that is transmitted! These packets can contain all kinds of sensitive information, including passwords, social security numbers, trade secrets, and private personal messages. A passive receiver that records a copy of…
