distributedchat 0.9.3

.

This program will implement distributed chat on virtual ring topology network. Furthermore this program will implement Chang-Roberts algorithm to achieve full ordering of messages.

Features:

• Nodes can freely join into existing ring, based on information about one node (IP:port). First node will join with itself into ring.

• Ring will recover from unexpected disconnect of one node at the time.

• One node will be elected as central authority (leader), all messages will be then passed through leader.

• Leader will be elected using Chang-Roberts algorithm.

• GUI in Qt, it will also have CLI.

• Encryption of messages.
