vEPC or virtual Evolved Packet Core is the most important platform in the telecom operator architecture. EPC is the core network of LTE system and responsible of handling the payload efficiently from performance and costs perspective. Modern EPC architecture platforms separate the user plan from the control plane in order to make the scaling independent. Thanks to this architectural split, the operators can dimension and adapt their network easily. Many operators have started virtualizing some not data intensive applications (IMS,TAS, PCRF, ..) and are looking today to continue the virtualization effort across the data core functions. Here is the list of some common functions that are becoming candidates for virtualization within the packet core: · Packet Data Serving Node Gateway (PGW) · Serving Gateway (SGW) · Mobile Mangement Entity (MME) · ...
