Omnipresent Ethernet - Technology Choices for Future End-to-End Networking

The authors propose an all-Ethernet end-to-end communication framework for the access, metro and core networks called Omnipresent Ethernet (or OEthernet). The proposed hierarchy is based on two inherent assumptions: Present manner of interconnection in carrier networks from a graph theory perspective and recent advances in Carrier Ethernet. The OEthernet approach makes good use of the advances of Ethernet from the LAN to the MAN and now to carrier networks, while inducing pragmatic traffic requirements for end-to-end communication. The OEthernet concept is a new end-to-end communication paradigm focused in particular to meet emerging service needs taking business requirements into consideration.
