Suppose host B sends a frame to host F. Describe how this frame reaches host F and show the switch table. (c) (d) Next, host F responds to host B. Describe how the respond frame reaches host B and show the switch table.

Consider the following virtual circuit network with three reserved virtual circuits: уC1: H1, А, С, Е, Н2 VC2: H3, A, F, D, H4 ус3: НЗ, А, F, D, E, H2 Host H4 Host H3 Нost H2 Host H1 Draw the routing table of router D and the routing table of router C. *you may design a table using the HTML editor or write the content of routing table record by record (record per line).

Just what are the benefits of using Lee's method for Routing? Talk about it from a designer's point of view.

A connection that connects two hosts may transport many packets at the same time. Please break down how much time is spent on each step of the processing of a freight load for me. Should the duration of one delay be predetermined, while the other delay's time might be flexible, depending on the situation?

A protocol for interleaved deliveries from two senders. Consider the figure below, which shows three nodes, A, B, and C. A and C are connected by a bi-directional channel; B and C are connected by a separate independent bi-directional channel. A and B can not communicate with each other. The goal of the protocol you will design is to transfer data from A and from B in a coordinated manner to C. The protocol between sender A and receiver C (and sender B and C) operates as follows. Senders A and B each receive data from their upper layer, via a call to rdt_send(data), which returns the data to be sent, exactly the same as the rdt protocols we studied in class and in the text. Senders A and B are to reliably send their sequence of data obtained via subsequent calls from rdt_send(data) to C. Node C should deliver to its application layer (via a call to deliver_data())a data item from A (as soon as it has correctly received that data item), followed by a data item from B (as soon as it has…

Complete the following table using the token bucket algorithm. Only the 4th column (transmitted packet) and the last row will be graded as highlighted. Bucket size = 1200 bytes. Token size = 850 bytes. Time 1 2 3 4 5 RX pkt 253 1104 1000 0 122 Bucket occupancy before packet transmission Transmitted packet Bucket occupancy after packet transmission

In a two-phase, total-order multicast system, messages are sent in the following sequence from node S to G1 and G2. G1 and G2 are the members of the group. S sends m1 to G1 S sends m1 to G2 S sends m2 to G2 S sends m2 to G1 Use the basic implementation of the Lamport clock. The clock s at each node start at: S: 4, G1: 6, G2: 1. Show the exchange of messages and their acknowledgments in a clock diagram using the basic implementation of Lamport's clock. In which order and at what times are m1 and m2 delivered?

Tracing through Layers Given the following scenario, trace out the path the packets will follow in the diagram provided. An alternate method of specifying your answer is given that requires no drawing Scenario: Your laptop A opens a web page from the server F, and the web caching server keeps a copy of the page on its way back to you. A second user A' (who takes your place on the diagram) is on the same LAN as you, connected also to Router B, and opens the same web page. Draw the path the HTTP message requesting the page would take from its origin point at A' to its destination point where the packet would go no further. See diagram for more info
