What is the project?

• The project is about implementing a Gossip Protocol.
• The main functionalities of the project :
  • Introduction : Each new peer contacts a well-known peer (the introducer) to join the group.
  • Membership : A membership protocol satisfies completeness all the time (for joins and failures), and accuracy when there are no message delays or losses (high accuracy when there are losses or delays).

Detail & Principle :

• Data Structure of Message :

typedef struct MessageHdr {
	enum MsgTypes msgType; 
	vector< MemberListEntry> member_vector; // membership list of source
	Address* addr; // the source of this message
}MessageHdr;

• Principle of Gossip Protocol : reference

How do I run the Grader on my computer ?

• There is a grader script GraderNew.sh. It tests your implementation of membership protocol in 3 scenarios.
  • Single node failure
  • Multiple node failure
  • Single node failure under a lossy network.

	$ chmod +x GraderNew.sh
	$ ./GraderNew.sh

Result

• Points achieved: 90 out of 90 [100%]
