Suppose A is connected to B via an intermediate router R, as in the previous problem. The A-R link is instantaneous, but the R–B link transmits only one packet each second, one at a time (so two packets take 2 seconds). Assume A sends to B using the sliding window protocol with SWS = 4. For Time = 0, 1, 2, 3, 4, state what packets arrive at and are sent from A and B. How large does the queue at R grow?
Please idk if i got this right
Consider a reliable data transfer protocol that uses only negative acknowledgements (NAKS). (a) Suppose the sender sends data only infrequently. Would a NAK-only protocol be prefer- able to a protocol that uses ACKS? Explain. (b) Now suppose the sender has a lot of data to send and the end-to-end connection expe- riences few losses. In this case, would a NAK-only protocol be preferable to a protocol that uses ACKS? Explain.

Implement in Packet Tracer a network of a fictitious organization with the following characteristics: - The organization will be made up of 4 units: 3 local Ethernet networks + 1 remote Ethernet network (via the Internet)- Local dependencies must connect to each other through a Backbone (links) between Switches- There must be 2 VLANs in 2 local dependencies- Throughout the organization there must be 2 IP networks with 2 subnets each. 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
