Using BGP path advertisements to implement routing policy. Consider the network below with interconnected provider networks and customer networks. Assume that provider network D only wants to carry traffic that originates in one of its customer networks (w, z) or is destined to one of its customer networks. It specifically does not want to forward datagrams between two other provider networks, since that transit traffic is neither sourced from, nor destined to, a customer network of D.

Concept explainers

Network transmission cabling

A network is a collection of devices connected by communication links. A device can be a computer or any instrument capable of sending and receiving data or information formed by other nodes toward the network. A channel that connects people or things is known as a network. It sends the data from one place to another. It is the basic concept of a computer, network, and data communications.

specifically does not want to forward datagrams between two other provider networks, since that transit traffic is neither sourced from, nor destined to, a
customer network of D.

One proposed solution that allowed mobile users to maintain their IP addresses as they movedamong foreign networks was to have a foreign network advertise a highly specific route to themobile user and use the existing routing infrastructure to propagate this information throughoutthe network. We identified scalability as one concern. Suppose that when a mobile user movesfrom one network to another, the new foreign network advertises a specific route to the mobileuser, and the old foreign network withdraws its route. Consider how routing informationpropagates in a distance-vector algorithm (particularly for the case of inter-domain routing amongnetworks that span the globe). a) Will other routers be able to route datagrams immediately to the new foreign network assoon as the foreign network begins advertising its route? Why? b) Is it possible for different routers to believe that different foreign networks contain themobile user? Why? c) Discuss the timescale over which other routers in…

The highlighted green values represent hop costs in which a data packet passes from node to node. A red X mark represents a broken link, a pre-existing connection with physical faults. ● Parameter A: Routers R4, R6, and R9 are having problems with faulty data connection and configuration in which passing data may experience packet loss. ● Parameter B: Routers R3 and R5 have experienced network intrusion due to the security measures not being configured properly.

(b) Node D is added to the left side with a connection to C. (c) A new link D-A is added. The failed B-F link is now restored. Describe what link-state packets will flood back and forth. Assume that the initial sequence number at all nodes is 1, that no packets time out, and that both ends of a link use the same sequence number in their LSP for that link, greater than any sequence number either used before.

Two users, one using Telnet and one sending files with FTP, both send their traffic out via router R. The outbound link from R is slow enough that both users keep packets in R's queue at all times. Discuss the relative performance seen by the Telnet user if R's queuing policy for these two flows is (a) Round-robin service. (b) Fair queuing. (c) Modified fair queuing, where we count the cost only of data bytes and not IP or TCP headers. Consider outbound traffic only. Assume Telnet packets have 1 byte of data, FTP packets have 512 bytes of data, and all packets have 40 bytes of headers.
