The deployment of the IP Multimedia Subsystem (IMS) brings a number of benefits to operators. One promised benefit is guaranteed service performance, which is necessary for a superior user Quality of Experience and differentiation of services from those found on the public Internet. To realize guaranteed service performance, resource and policy-based admission control is specified by the standards for Next-Generation Networks and IMS.

Operax provides a common platform for dynamic Resource and Admission Control, and the real-time guarantee of QoS for all services on a per-session basis. An IMS architecture deployed utilizing Operax Resource Controller solutions strengthens the operators’ service delivery architecture and improves the capability to deploy services efficiently and with the necessary performance.

Solution capabilities include:

• Guaranteed QoS - Operax Resource Controller provides guaranteed QoS for all services on a per session basis.
• Simplified service deployment - Operax Resource Controller integrated with IMS provides automated QoS for all IMS-based services.
• Simplified network operations - Operax Resource Controller provides the operational benefits of connection oriented behavior in a connection less network.
• Flexible and future proof - Operax Resource Controller models any networking technology and topology without imposing any architectural requirements on the network.

Operax offers carrier-grade dynamic Resource and Admission Control products for IP QoS enforcement. These operate in the control plane between the application and the transport layers. Operax products are based on a unique real-time resource and policy modeling capability. This provides a common platform for flexible and operationally-efficient implementation of per-session QoS guarantees. Operax products are multi-service and multi-technology, supporting the operator in deploying IMS-based services in networks featuring multiple transport technologies sourced from multiple vendors.

Within IMS solutions Operax provides the Operax Resource Controller 5500 for use in access and aggregation networks and the Resource Controller 5700 for use in Core IP/MPLS and PBT networks. When used together, they provide true end-to-end dynamic Resource and Admission Control across access, aggregation and core network operations.
