Appendix B. Sproc Generic Layer Rules

• src_proc_id: This attribute should have one value: "machine: <machine_name>; process: <process_id>; thread: <thread_id>". The machine name may either be an dotted octet IP address or a (partially or fully qualified) domain name. The process and thread ids should be ASCII base 10 representations of positive integers. All messages must have this attribute. On single-threaded systems, the thread id should be 0.

• dest_proc_ids: This attribute should have n values, where n is the number of destination specifications. Each value should be of same form as described above, except that any of <machine_name>, <process_id>, or <thread_id> may be replaced by the character "*" to indicate any value should match that field. All messages must have at least one value in this attribute, even if it specifies that any destination is valid (i.e., "machine: *; process: *; thread: *"). Processes should see that they match at least one destination specification before processing a message.

• time_sent: This attribute should have one value equal to the ASCII base 10 representation of the system time on the sending machine when the message was first received by the Sproc Generic Layer handlers.

• time_recvd: This attribute should have one value equal to the ASCII base 10 representation of the system time on the destination machine when the message was first received by the Sproc Generic Layer handlers.

Ignored here are issues about time representation (e.g., seconds since 1/1/70 0:00 GMT, etc.). These issues should be addressed by the OHSWG.
