Go-back-N & Selective repeat protocol

hi every body ... :(:(:(

please help me ... to solve this problem ...

in this problem you are required to simulate and compare two Reliable Data Transfer protocols (RDT) that provide reliability to applications using it. The reliability is achieved using the Sliding Window protocol. You will first implement the Go-Back-N version with no buffer at the receiver. Then, you will implement the Selective Repeat version. Consider the channel between the sender and receiver can lose and delay packets.
To implement the protocols –using any language- you will write three functions: sender(), receiver() and channel().

You have to compute and provide plots for the dropping probability depending on the following input parameters:
1. Window size.
2. Packet loss rate.
3. Retransmission timeout.


pleaaaaaaaaaaaaaaaaaaaaaaase help me ....

This isn't a Java question, it's an advanced computer science question involving the implementation of network protocols...

nooooooooooooo :mad:

Steve ... in this problem ... it want to implement this protocol by java ... and its difficult for me to implemented in java.... i know the concept.. But when i want to write in java.... I can not ... please help me.... it’s appear... You are genius in java.. :(:(

Seriously, I have no clue what you are supposed to do. What languages do you know? What subroutines would you create in another language?
