Now and days, people are talking about virtualization and its advantages. I want to know how virtualization can help for a telecom operator. Which components can be virtualized and how can an operator save money ?

Before virtualization concept/technology, each node such as MME, SGW etc were combination of specific hardware and software. There is a technical term vendor locking. Vendor locking means if an operator wants to deploy a particular node such as MME, it has to buy a box (hardware + software) together. For vendors it was a profitable business model but for operator it was more CAPEX/OPEX. Now using virtualization technique, all these nodes have been decoupled from hardware.
Now these nodes run in the form of virtual machine also known as VNF (virtual network function) and these VNF/VM are instantiated in data centers (public or private clouds).
In order to reduce CAPEX/OPEX, operator would prefer to deploy vEPC components and at the same time many more players will jump into telecom node development because of removal of hardware dependencies.
This is my view of seeing vEPC v/s normal EPC.

Well, now and days when we talk about SDN, it mean we are going to use white box switches. AFAIK switches works at the L2 level and routers work at the L3 level. Is the same concept applicable for white box switches or they can have support for routing also ?
