site is added, configuration is done only on the provider edge router. If site 4 is to be added in the peer model in figure 4, then only the PE router is to be configured. The other CE and PE routers need not be configured or modified. 3. The data packet contains the following information: Destination IP address, Class of Service (COS) and Quality of Service (QoS) information. 4. There are less network delays as there is no circuit established, and no maintenance and tear down process required.…

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…

UML 91.561 Computer & Network Security I HomeWork 1 Name – Nrupen Abnave Student ID -01382247 1.1 (a) Describe the major structure of a TCP packet and explain the main functions of the TCP headers. - TCP is a transport layer protocol and is connection oriented. Its reliable connection, has error checking and flow control. TCP Headers: 32bits Source and Destination Ports – Each 16bit number. Indicate which application is using the communicating stream. Used by most common…

Protocol (TCP) and High-Level Data Link Control (HDLC) ensure the reliability of data. They ensure that data transfers from one node to the other without any error. Moreover, the data is transferred between the network nodes in the form of packets. These packets are not sent in any particular order; therefore, TCP and HDLC are also required in order to ensure the sequencing of data. Automatic Repeat Request or ARQs also help in detecting errors in…

interview and during the packet building process. Williams told the Station Commander that the Navy was not going to take him back on active duty and wanted to pursue a career with the Army with active duty being the end goal. Williams was motivated and assisted in getting all the source docs and his packet built with little to no delay. He agreed on an Enlistment date of 22NOV. During a follow up today 17NOV, Williams informed his recruiter the Navy approved his packet after a long delay and…

Inevitably there is a security risk in accessing any database on the internet. The internet houses a variety of malware. Engineers attempt to discover security risks users experience and mitigate them. VPN connections can enable users and organizations dealing with confidential information the ability to avoid having their data observed or stolen. VPNs are not perfect, they do however, provide an avenue allowing the ability to transfer data more securely. To understand VPNs in their entirety…

connection structure. HTTP only transfers larger amount of data, and needs a genuine mechanism. DNS requests are short packets that issues the IP address for a name and maybe some other dependable name server addresses. The reliable protocol semantics of TCP would be costly in the DNS case. b) What could happen in DNS if its UDP based request or response packet is lost If DNS request packet are lost, the resolver would devote that there is a short-term failure in name resolution or it could…

Populism “influenced the tactics and techniques of Lenin and Bolshevism”, Lenin took the idea of promoting self-interest and believing in nothing from nihilism, and he took the use of violence from anarchism, which helped justify the Red Terror (Packet). Lenin’s goal was to overthrow…

GUI (Graphical User Interface), Wireshark allows a live view of the network traffic on the network card it is listening to. 2.9 Our approach to improving the throughput of QoS with SDN: 2.9.1 Setup and run Mininet and controller The first step installs Mininet in Ubuntu operation system, we are don't using a virtual machine and then install Ryu controller in OS. 2.9.2 Create custom network We must be to create a custom network as appropriate with our thesis such as star topology or random…
