Abstract

A combination of a common key routing (CKR) method and data proxy architecture (DPA) method may be used to route communication messages in a telecommunication network to achieve improved data locality and reduce secondary key lookups. A processor in a multiprocessor computing system may receive a first communication message that includes subscriber identifiers that uniquely identify a subscriber, generate a common key based on the subscriber identifiers, identify a first logical scalable unit that includes a first database memory that stores subscriber data relating to the subscriber via a database application programming interface (API) and the common key, store the first communication message in the first database memory included in the first logical scalable unit, and receive a second communication message in response to storing the first communication message in the first database memory and routing the second communication message to another component the telecommunication network.

receiving a communication message that identifies the subscriber using a different identifier than the two or more subscriber identifiers included in the first communication message.

9. The method of claim 6, further comprising:

retrieving the third communication message from the second database memory by a second application component of a second application processor;

retrieving the subscriber data from the second database memory;

performing application-level operations using the subscriber data retrieved from the second database memory and the retrieved third communication message;

generating a fourth communication message based on the subscriber data retrieved from the second database memory; and
