6. An ISP has the following Routing Table depicting the 7 prefixes he has as customers. What is the smallest number of prefixes he will need to advertise to the outside world announcing reachability to all its customers but no other? If more than one prefix, list them separated by commas (This question is about address aggregation) a. # of Prefixes: b. Prefix (es): 212.56.146.0/24 212.56.147.0/24 212.56.148.0/24 212.56.149.0/24

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…

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

Consider a router that interconnects three subnets: Subnet 1, Subnet 2, and Subnet 3. Suppose all of the interfaces in each of these three subnets are required to have the prefix 223.10.128/24. Also suppose that Subnet 1 is required to support at least 50 interfaces, Subnet 2 is to support at least 100 interfaces, and Subnet 3 is to support at least 12 interfaces. Provide three network addresses (of the form a.b.c.d/x) that satisfy these constraints.
