Abstract
A new end-to-end communication solution called Omnipresent Ethernet
(OEthernet) is demonstrated through a test-bed. The solution takes into
consideration contemporary interconnection methodologies in
enterprise/provider networks from a generalized graph perspective. The aim
is to be able to convert any network graph into a known symmetric graph by
simple algorithmic treatment. The virtual graph that we create is a binary
tree—whose representative node is a binary node with a 1$\,\times\,$2 interconnection architecture. The binary tree transformation of
irregular network graphs leads to source routing and binary routing which
results in significant performance and cost advantages. Addressing and
routing in binary trees can be made possible at the Ethernet layer taking
advantage of the advances in Carrier Ethernet. The resulting OEthernet
solution facilitates communication without IP—enabling
applications to ride entirely on OEthernet frames. In this paper, we built a
test-bed that demonstrates the OEthernet concept. The test-bed is a 25 node
binary tree, exemplified by a metro core (optical backbone) and an access
edge network in optical as well as copper domains. The test-bed supports
triple play applications, in particular, video-on-demand. Measurements are
made for latency, jitter and throughput and we observe that the OEthernet
solution is lower cost, more effective and energy efficient than regular IP
networking approaches. An all-optical version of the OEthernet solution is
also presented.
