Suppose there are two ISPS providing WiFi access in a particular café, with each ISP operating its own AP and having its own IP address block. A. Further suppose that by accident, each ISP has configured its AP to operate over channel 11. Will the 802.11 protocol completely break down in this situation? Discuss what happens when two stations, each associated with a different ISP, attempt to transmit at the same time. B. Now suppose that one AP operates over channel 1 and the other over channel 11. How do your answers change?

Question

Suppose there are two ISPS providing WiFi access in a
particular café, with each ISP operating its own AP and having
its own IP address block.
A. Further suppose that by accident, each ISP has configured
its AP to operate over channel 11. Will the 802.11 protocol
completely break down in this situation? Discuss what
happens when two stations, each associated with a different
ISP, attempt to transmit at the same time.
B. Now suppose that one AP operates over channel 1 and the
other over channel 11. How do your answers change?

Given what we know about transmission delay and the following: A web client and a web server separated by one intermediary router. • Each link carries data at 1Mbps with an MTU of 8192 bytes • Each link is 1000 km long with a propagation speed of 250000 km/s • Zero processing and queueing delays • Connection management packets (packets used for opening a connection, confirming a connection and acknowledging receipt of information) contain no data and all packets have 125 bytes of overhead on top of any data they may contain. • The web client makes an HTTP request to the server that is 250 bytes long. • The requested data is 4 kilobytes in size with 500 bytes of overhead for the HTTP status and headers What is the RTT to open the connection? а. b. How long would it take for a web client to complete the request? You can ignore any time needed to close the connection.
To get around the problem of sequence numbers wrapping around while old packets still exist, one could use 64-bit sequence numbers. However, theoretically, an optical fiber can run at 75 Tbps. What maximum packet lifetime is required to make sure that future 75 Tbps networks do not have wraparound problems even with 64-bit sequence numbers? Assume that each byte has its own sequence number. as TCP does.
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 ...
