An IP address can be written as a 32-bit number. For a class B network, the two most significant bits are set to 10. The 16 most significant bits are used as a network ID, and the 16 least significant bits are used as a host ID. However, the host ID cannot be all O's or all 1's. How many hosts (i.e., host IDs) can there be on a class B network? Type your answer.
Consider transferring an enormous file of L bytes from Host A to Host B. Assume an MSS of 536 bytes. a. What is the maximum value of L such that TCP sequence numbers are not exhausted? Recall that the TCP sequence number field has 4 bytes. b. For the L you obtain in (a), find how long it takes to transmit the file. Assume that a total of 66 bytes of transport, network, and data-link header are added to each segment before the resulting packet is sent out over a 155 Mbps link. Ignore flow control and congestion control so A can pump out the segments back to back and continuously.
Please idk if i got this right
An Internet user would like to transfer a message from his computer (host A) to another computer (host B). The size of the message passed to the IP layer is 3800 bytes. The datagram(s) carrying the message will have to cross two routers (R1 and R2) and 3 networks (NET1, NET2, and NET3) as described in the above figure. Each of these networks has a specific MTU (for example the MTU of network 1 is 1500 bytes. MTU here stands for Maximum Transmission Unit, the largest data that a frame can carry). Fill the table with the IP datagram(s) needed right after passing through NET3 (no need to show your fragmentation for N1 or N2). Assume a 2-byte options in the header. Show all your details (for partial points in case your numbers are incorrect). NET1 MTU=1500 R1 NET2 MTU=640 R2 NET3 MTU 1500 V BIU Fragment # Format Offset Flag (3 bits) Data Length Total Length ...
Communication between routers on the per-router control plane (or classical network) is accomplished using IP destination forwarding. To what extent does this message forwarding mechanism based on a recipient's IP address have restrictions? Provide at least three limitations, illuminating them via specific examples. The question is, what part does Software-Defined Networking (SDN) play in solving these problems? This will be explained with certain instances.
2. Consider a slotted TDM hierarchical network in which there are 8 computers sharing a 10 Mbps channel to a router R1, sending packets to R1 which must all be forwarded by R1 over an outgoing link (called the MAN link), as shown in Figure 1. Computers A-H always have packets waiting to be sent, so no timeslot on the shared LAN is idle. Ignore the propagation delay on the LAN. The MAN link outgoing from R1 is a 100 Mbps link. The network layer protocol in use has a PDU with exactly 40 bytes of header and exactly 200 bytes of payload (SDU). The DLC layer protocol in use on the LAN has a PDU with exactly 40 bytes of header and 20 bytes of trailer. The DLC layer protocol in use on the outgoing link from R1 has a PDU with 40 bytes of header and no trailer. The physical layer does not impose any bit overhead in either channel. Use 1 Mbps = 1000000 bps. B D E F G H R1 R2 Figure 1 (a) What is the transmission delay of a bit for Computer A? (b) What is the transmission delay of a DLC PDU for…
For each ping attempt (ping by IP address), circle whether the ping succeeds or fails. The stated subnet mask is the subnet mask which A applies to the source and destination IP addresses in the ping packet. For this problem, assume that the router is NOT able to send a ping request packet out via the same port upon which it arrived. Pay close attention to the network connectivity devices. 13 IP 200 10.3.3 MAC 63 Succeeds Fails A pings Z Succeeds Fails Subnet Mask = 255.255.255.0 A pings C IP 200.10.3.3 MAC 63 .

The different IP networks must communicate with each other.- A static routing method or a dynamic routing method must exist- The remote unit must be integrated into some IP network through a VPN link- Each local office must have IP telephony (VoIP). At least one IP phone for each unit.- In each unit there must be at least 5 user PCs- Each PC must have Automatic IP configuration (DHCP)- DHCP, DNS and Web Servers must exist - All rooms must have access to the Internet through NAT-PAT- There must be a Wi-FI network in each unit
