Universal Actor Locators (UALs)

The first item specifies the protocol used for remote message sending. The second item indicates the theater's machine name and port number. If a port number is not specified, the default port number (4040) for the theater is used. The last part specifies the relative locator name of the actor in the given theater.

SALSA's universal naming scheme has been designed in such a way to satisfy the following requirements:

• Platform independence: names appear coherent on all nodes independent of the underlying architecture.
• Scalability of name space management
• Transparent actor migration
• Openness by allowing unanticipated actor reference creation and protocols that provide access through names
• Both human and computer readability.
