Filed:

Dec 30, 1998

Appl. No.:

09/223234

Inventors:

David W. McDaniel - Dallas TX

Assignee:

Alcatel USA Sourcing, L.P. - Plano TX

International Classification:

H04M 1500

US Classification:

379134, 37911204, 3791121, 37922109

Abstract:

A service control point ( ) includes an overload control system ( ) that determines an overload rating ( ) for an intelligent processing unit ( ). The overload control system ( ) includes a latency estimator ( ) that requests and receives a latency ( ) for a service logic interpreter ( ). A queue depth store ( ) receives a queue depth ( ) from the service logic interpreter ( ). A common memory ( ) stores the latency ( ) and the queue depth ( ) in memory mapped files. A load estimator ( ) determines the overload rating ( ) in response to the latency ( ) and the queue depth ( ). The load estimator ( ) compares the overload rating ( ) to a previous overload rating and issues an internal problem report if a difference is detected. A TCAP interface ( ) and a service logic program ( ) assess the overload rating ( ) to determine if incoming service requests should be passed on to the service logic interpreter ( ), rerouted, or discarded. The load estimator ( ) provides the overload rating ( ) to an overload server ( ).

H04M 1/66

US Classification:

709245

Abstract:

A communication system includes translation modules that provide address hopping to secure packet-based communications. A transmitting translation module modifies source and/or destination addresses of communicated packets and a receiving translation module resolves each modified source and/or destination address into the original source and destination addresses for the packets.

International Classification:

H04L 1256

US Classification:

370416

Abstract:

A telecommunications network (10) includes a plurality of transport node controllers (18) that interface with a plurality of local communication processors (16) for the transfer of telecommunications information between subscribers (14) associated with the local communication processors (16) and also for subscribers remote from the transport node controller (18). The transport node controller (18) includes a buffer memory (24) with a pool of buffers (26). A local processor controller (22), in conjunction with a remote processor (20), allocate the buffers (26) within the buffer memory (24) among the plurality of local communication processors (16) and remote communication processors communicating to the transport node controller (18) through a message transporting network (12). The local processor controller (22) assigns a buffer (26) to each of the plurality of local communication processors (16). A message processed by one of the local communication processors (16) is temporarily stored within its associated message-in buffer (26).
