- When starting a space and providing the port as part of the URL - i.e.
java://localhost:PORT/container/space
- the specified port will be used both for the RMI registry listener and also for the container to register into the RMI registry. - The Jini Lookup Service uses unicast and multicast announcements and requests.
- The multicast discovery protocol uses ports 4174.
- You can completely disable multicast announcement traffic. Refer to the Lookup Service Configuration or GigaSpaces Over a Firewall sections for more details.
- When running a clustered space using replication via multicast, additional ports are used.
