Distributed architecture laboratory

Protocol

• Timeout: 1 second
• Communication: Using binary format

Architecture

• n Services
• m Linker (public IPs, cannot add new linkers after initialization)
• k Clients

If a linker, service or client does not reply after the timeout, it is considered as dead.

Launching linkers:

java Linker <linker id>

The linker id is the line number in linker.txt, associating a specific id to a port

Example: java linker 1

Launching Services:

java Service <type> <port>

type: Type of service - "reply" - "time" - "sum"

port: Port of service

Launching clients:

java Client <type> <port>

Same specifics as with services.

NEEDED:

linkers.txt file in the root directory with the following format:

127.0.0.1:9090 127.0.0.1:9091 127.0.0.1:9092 . . . 127.0.0.1:<last_port>
