The minimum cost will be covered to reach B One can clearly see that minimum cost from F to B is as follows -
F -> A -> B which requires a buffer of 8 + 10 = 18
Hence packet buffer of B is 18
I have tried to explain it in very simple language and I hope that i have answered your question satisfactorily.Leave doubts in comment section if any.

A router that has the routing table in Figure 8-11 receives an incoming IPv4 packet. The source IPv4 address in the arriving packet is 10.55.72.234. The des-tination IPv4 address is 10.4.6.7. The TTL value is 1. The Protocol Field value is 6. What will the router do with this packet? (Hint: Carefully consider all the fields in the IP and TCP headers. Think like a router.)
3. Suppose there is exactly one packet switch (or router) between a sending host and a receiving host. The transmission rates between the sending host and the switch and between the switch and the receiving host are R1 = 1Mbps and R2 = 2Mbps, respectively. Assuming that the switch uses store-and-forward packet switching, what is the total end-to-end delay to send a packet of length 18000bits? Assume that the propagation speed is 2 * 108 meters/sec, the distance between source...

QUESTION 1 "A single router is transmitting packets, each of length L bits, over a single link with transmission rate R Mbps to another router at the other end of the link. Suppose that the packet length is L= 12000 bits, and that the link transmission rate along the link to router on the right is R = 1000 Mbps. What is the maximum number of packets per second that can be transmitted by the link (use a whole number)?"...

Mirror has gradient m, and incoming ray has gradient a we express the gradient of the outgoing ray in terms of a and nm am2 2m -a 1 +2am-m2 Now consider the ellipse (a) Show that the point A (-1/3,4/3) lies on the ellipse. (b) Calculate the gradicnt of the tangent linc to the ellipse at the point A. (c) source of light is placed at F the ray that starts at F and goes to A. (0,1). Calculate the...
Test Your Understanding 10. a) Distinguish between Step 1 and Step 2 in the routing process. b) If any row other than the default row matches an IPv4 address, why will the router never choose the default row? c) Which rows in Figure 8-11 match 128.171.17.13? (Don't forgst the default row.) Show your calculations for rows that match. d) Which of these is the best-match row? Justify your answer. e) What rows match 172.40.17.6? Show your calculations for rows that...

Refer to the network figure above, showing two Ethernet Subnets
connected through an IP Router, for questions #1, #2 and #3. For
each device, both its Internet Protocol (IP) address and its MAC
address (also called the Physical address or the Ethernet address)
are shown. The Subnet Mask used by all devices is 255.255.255.192
(which is same as prefix length “/26”).

1. For TCP end-to-end flow control, suppose the capacity of the
receiver buffer is 10 packets. Suppose the packets that are being
queued in the receiver buffer are packets 4, 5, 6, 7, 8, 10, 11.
What is the advertised window size the receiver sent to the sender?
Suppose packet 12 is the last packet sent by the sender. What’s the
effective window size at the sender? Can the sender send out packet
