Abstract

UnifyCore is a concept of SDN centric, OpenFlow based and access agnostic network architecture, which changes the way networks are being built today. It is designed in a way, so present access technologies can be easily integrated in it. It provides set of architectural components and rules, which help to easily decouple components of the access technology and put their functionalities into UnifyCore building blocks. This simplifies the overall network architecture and allows the use of common transport core for all access technologies. First proof of concept built on UnifyCore is the GPRS network, which is a challenge for SDN, since it does not have split user and control plane transport. In this paper we introduce and explain features that allow fully SDN UnifyCore to be integrated with existing legacy network infrastructure (switches/routers).
