SDN As A Matchmaker For Remote Phy Architecture

摘要

The Remote Phy (RPHY) architecture facilitates the separation of MAC (Media Access Control) resources from Phy (Physical layer) resources. The follow-up question is how do we pair them up? The most straightforward method is to view the Remote Phy Device (RPD) in the RPHY architecture as a fixed "satellite" of the MAC and use static configuration for pairing them up. But this would only be a starting point. This paper will outline how a dynamic and flexible separation of these resources facilitates new options for OPEX savings as well as new load sharing and availability models. The paper will also outline an SDN architecture to guide the implementation of these new capabilities.
