Types Of Protocols

A network protocol is a collection of rules that governs the exchange of data between devices connected to the same network. In other words, network protocols are rules that specify how devices communicate or transfer data over a network. The sender and receiver systems must obey the standards to facilitate communication between them.

Consider that only a single TCP (Reno) connection uses one 10Mbps link which does not buffer any data. Suppose that this link is the only congested link between the sending and receiving hosts. Assume that the TCP sender has a huge file to send to the receiver, and the receiver's receive buffer is much larger than the congestion window. We also make the following assumptions: each TCP segment size is 1,500 bytes; the two-way propagation delay of this connection is 150 msec; and this TCP connection is always in congestion avoidance phase, that is, ignore slow start. A. What is the maximum window size (in segments) that this TCP connection can achieve? B. What is the average window size (in segments) and average throughput (in bps) Of this TCP connection? C. How long would it take for this TCP connection to reach its maximum window again after recovering from a packet loss?
Does this make sense to you, or do you believe it to be incorrect? Consider the most recent SampleRTT on a TCP connection to be one second. In order for the connection to be deemed active and functioning, the current TimeoutInterval value must be greater than one second.

Assume that a bottleneck connection with a rate of R bps carries two TCP connections. In both cases, there is a big file that must be downloaded (in the same direction over the bottleneck link). The files are all transmitted at the same time How much data will TCP be able to transmit each connection?
Consider a TCP connection with the following parameters: a) Initial ssthreshold = 8 b) Round Trip Time (RTT) = 10 milliseconds c) Retransmission Timeout period = 40 milliseconds d) Segment size = 2700 bytes The TCP connection was used to transfer 19 data segments, numbered 1 through 19. While sending the segments, data segment 10 was lost the first time it was sent (but arrived at the receiver properly upon being retransmitted). There were no other segment losses apart from the aforementioned. Assume that data segments received out-of-order are buffered at the receiver. What is the average throughput obtained in sending all the data segments (in bytes/sec)? Draw a diagram to show the transmission of the segments in detail.
Consider one TCP connection on a path with a bottleneck link with capacity L. We have a file of size F(assume F is a very large file size). If TCP segment size is B bytes, the two-way propagation delay is tp and connection is always in congestion avoidance phase, find the following: A. Maximum window size that TCP can achieve B. Average window size and average throughput in this TCP connection C. Time it will take from connection establishment to reaching the maximum window size.
UDP and TCP use 1s complement for their checksums. Suppose the receive received two 3-bits payload messages: 010, 001. The checksum received is 100. Find all possible original messages. How many errors were made during the transmission?

Assume for the sake of this example that a packet is being sent from a source to an address at the other end of the network via the fixed route. List all the delays' varied causes as well: How many delays are roughly time-dependent and how many are roughly continuous for how long?
