Abstract

A method is provided for managing memory resources in a service gateway environment. The method includes: receiving a service request, the service request having an associated memory space requirement that exceeds total available memory space associated with the gateway environment; determining a number of dependent service instances for each service instance; determining an accumulative memory space requirement for each service instance; identifying a subset of service instance whose memory space requirement exceeds the memory space requirement of the service request, the subset having a minimal number of the service instances; and performing a memory resource management operation in relation to the identified subset of service instances.

Dependent claims

A method for managing memory resources in a service gateway environment, the service gateway environment having a plurality of service instances where at least one of the plurality of service instances being dependent on another service instance of the plurality of service instances, comprising:

receiving a service request, the service request having an associated memory space requirement that exceeds total available memory space associated with the service gateway environment;
determining a number of dependent service instances for each service instance of the plurality of service instances;
determining an accumulative memory space requirement for each service instance of the plurality of service instances, the accumulative memory space requirement accounting for service instances that depend from a given service of the plurality of service instances;
identifying a subset of service instances of the plurality of service instances whose memory space requirement exceeds the memory space requirement of the service request, the identified subset of service instances having a minimal number of the service instances of the plurality of service instances;
and
performing a memory resource management operation in relation to the identified subset of service instances.

A method for managing memory resources in a service gateway environment, the service gateway environment having a plurality of service instances, comprising:

(a) receiving a service request, the service request having an associated memory space requirement that exceeds total available memory space associated with the service gateway environment;
(b) determining an accumulative memory space requirement for each service instance of the plurality of service instances;
(c) determining a number of dependent service instances for each service instance of the plurality of service instances;
(d) determining a ratio for each service instance, of the plurality of service instances, where the ratio is defined as the accumulative memory space requirement divided by the number of dependent service instances;
and
(e) performing a memory resource management operation in relation to the service instance of the plurality of service instances having the largest ratio.
