- The first thing needed is a IP-addressing range to use in our network. Since this assignment is done in a laboratory setting, we don't have to comply to the RFC1918[2] standards of private IP-addressing. An IP address is written in the form shown in equation (2.1.1). X grpl grp2 grp3 grp4 X grpl grp2 grp3 grp4 We need however to take into consideration that the address range of 224.0.0.0/3 have been reserved, for amongst other thing multicast. Because of this, we will need to use another modulus-value on the first octet when we are generating a usable ip-address range. Start by creating your groups unique IP-address range using equation (2.1.2) where {x,y EZ | 0≤x≤ 223,0 ≤ y ≤ 255} (2.1.2) where {x EZ | 0≤x≤ 255} Where each octet will be based on each group members birthday. Value X is calculated according to equation (2.1.3), and value Y is calculated according to equation (2.1.4).

In short, the TCP / IP protocol suite is classified as stateless, which means that each client request is considered new because it has nothing to do with previous requests. Being stateless, network routes are released so that they can be used continuously. Answer the following questions briefly. How does resource reservation work in the TCP / IP model? Which TCP / IP layer is responsible to reserve resources across a network using the TCP / IP model? What protocol assigns an IP address to the client connected to the Internet? Checksum is used by various protocols on the Internet, but not at the one of TCP / IP Explain.arrow_forwardSuppose that a router interconnects three subnets, where all the interfaces ofthe subnets must have the prefix 164.132.62/24.

Host A converts analog voice to a digital 64 kbps bit stream on the fly. Host A then groups the bits into 56-byte packets. There is one link between Hosts A and B; its transmission rate is 2 Mbps and its propagation delay is 10 msec. As soon as Host A gathers a packet, it sends it to Host B. As soon as Host B receives an entire packet, it coverts the packet's bits to an analog signal. How much time elapses from the time a bit is created (from the original analog signal at Host A) until the bit is decoded (as part of the analog signal at Host B)?arrow_forward1.

- Consider a network connecting two systems located 4000 kilometers apart. The bandwidth of the network is 500 x Mbps. The propagation speed of the media is 4 × 106 meters per second. It is needed to design a Go-Back-N sliding window protocol for this network. The average packet size is 107 bits. The network is to be used to its full capacity. Assume that processing delays at nodes are negligible.

Suppose Host A then sends two segments to Host B backto-back. The first and second segments contain 80 and 40 bytes of data, respectively. In the first segment, the sequence number is 127, the source port number is 302, and the destination port number is 80. Host B sends an acknowledgment whenever it receives a segment from Host A. d. Suppose the two segments sent by A arrive in order at B. The first acknowledgment is lost and the second acknowledgment arrives after the first timeout interval. Draw a timing diagram, showing these segments and all other segments and acknowledgments sent. (Assume there is no additional packet loss.)
