The document outlines the design of a peer-to-peer system in Java that facilitates message and content exchange between nodes across two groups, aiming for at least 100 pairs. It emphasizes converting lower-case text messages to uppercase and suggests adapting this functionality for multimedia files. Additionally, it discusses TCP socket creation for communication while addressing threading and socket management for efficient data transmission and collection of various transmission metrics.

1. Code in java
Design the peer to peer system in which many pairs of nodes (from both clusters/groups) as
possible or at least 100 pairs to exchange messages or content data. A text message sent in
lower-case be converted to uppercase and returned. You may replace the text-file with something
more meaningful or practical such as videos and audio file. If so, then replace the character-
conversion logic inside the server-side code to reflect this new application.
Create a new TCP socket for, e.g., N1, while it waits on its initial request to the S-Router for group
N; and also how the S-Router for group M instructs node M1, for example, to connect to N1 using
this new TCP link. Make use of the threading code and be careful of creating several sockets and
leaving them open (not closed) at the same time. Note that the S-Router-S1 and S-Router-S2
communicate using a pair of TCP sockets with port numbers 5555 and 5556 respectively.
The test files exist on any node which is designated as a sender-Client/Peer. Collect and analyze
data for such parameters as average message sizes, average transmission time, average time for
the routing-table lookup, number of bytes/units of data transferred per unit time, average number
of message drops.
