| + | ===== Subsequent Phases of vIMS Testing ===== | ||
| + | As described above, the proposed vSBC test case is specifically intended to explore the performance of OPNFV in the IMS user plane. For a broader characterization of OPNFV in the context of vIMS, a more complete implementation of vIMS should be tested on OPNFV. | ||
| + | |||
| + | The vIMS test case can be progressively expanded by adding more and more of the distinct functions defined by the IMS architecture. A logical next step beyond vSBC testing would be to add a virtualized IMS core. The VNF implementation proposed for this purpose is Clearwater Core, an open source implementation of the IMS core functions from Metaswitch Networks. See [[http://www.projectclearwater.org/]]. | ||
| + | |||
| + | Clearwater is implemented with a scale-out architecture using stateless SIP processing elements allied with a distributed, scalable, fault-tolerant state store based on well-known open source elements. With Perimeta SBC providing a virtualized P-CSCF and Clearwater Core providing virtualized S-CSCF, I-CSCF, BGCF and (optionally) AS, all the key call processing functions of a vIMS could be tested. The same SIP traffic generation capabilities used to test vSBC would also be needed to test this more complete implementation of vIMS. With this test setup, the performance of OPNFV could be characterized in the context of vIMS in both control plane and user plane. | ||
| + | |||
| + | An even more complete test of vIMS on OPNFV could be accomplished by adding further functional elements such as vHSS, vPCRF etc. Also, the vIMS could be layered on top of vEPC to enable the testing of a complete virtualized VoLTE solution. | ||
