摘要:
A method for balancing traffic among parallel links connecting two signalling points of a Common Channel Signalling System (SS7) when one or more of the links becomes unavailable. A change-over process causes SLS (Signalling Link Selection) field values originally associated with the unavailable link to be reassigned to remaining available links on a distributed basis. A change-back process, used where a previously unavailable link is restored to service, causes SLS field values to be reassigned from the other available links to the restored link.
