The TTL behaviour for IP-to-Label or Label-to-IP connections is depicted in the below image. Ingress LSR receives a packet with a TTL value of 289 arriving. What would the TTL value be for the ingress and egress LSRS? the letters (A, B, C, D, E, F, G, and H). TTL=289 MPLS Label Ingress LSR TTL = Ac TTL= 8: LSR TTL=C TTL-D: LSR TTL=E: TTL=F: Label Switched Path LSR TTL - G: TTL=H: Egress LSR

It is possible for a series of packets to be sent from one host to another over the same connection. Please break down the time it takes for a single package to go from beginning to conclusion. Is it expected that one of the delays would last a certain period of time while the other delay's length will be more malleable?

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…

What a router does when it gets a packet with an unknown destination network address is described in the following.

Assume the maximum transmission unit (or MTU) of an IP packet on 100 Mbps Ethernet is set at 1500 bytes. Also, assume we are sending our file using IPv6 at the Network layer and UDP at the Transport layer. A typical IPv6 header consists of 40 bytes, a UDP header consists of 8 bytes. Answer the following three questions based on the information provided above. For all answers, enter a decimal integer value without formatting (no commas). 1. How many packets do we have to send in order to transfer a file of 24KB over 100 Mbps Ethernet? packets 2. How many bytes do we have to send at the network layer in order to transfer the above file entirely? bytes 3. How many bytes do we have to send at the data link layer in order to transfer the above file entirely? Assume that the Ethernet header is 14 bytes and the frame checksum is 4 bytes. bytes

Refer to the network figure above, showing two Ethernet Subnets connected through an IP Router, answer the following question 1-5. The devices in each subnet are connected locally to each other through layer two intermediate devices such as Ethernet switch and ethernet hub. For each device in the subnets, 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 255.255.255.240 (which is the same as the prefix length “/28”). 1. If Client #1 wants to send a broadcast packet to all the devices on the left subnet (containing client #1, client #2, client #3) what destination IP address should be used? (Mention in both binary and decimal format.)  2. What is the first and last assignable IP address for the left subnet above (containing client #1 and #3)? (Mention in both binary and decimal format.)
