Abstract
This paper presents the concept of Open Cloud
eXchange (OCX) that has been proposed to bridge the gap
between two major components of the cloud services provisioning
infrastructure: Cloud Service Provider (CSP) infrastructure; and
cloud services delivery infrastructure which in many cases
requires dedicated local infrastructure and quality of services that
cannot be delivered by the public Internet infrastructure. In both
cases there is a need for interconnecting the CSP infrastructure
and local access network infrastructure, in particular, to solve the
"last mile" problem in delivering cloud services to customer
locations and individual (end-)users. The OCX remains neutral to
actual cloud services provisioning and limit its services to Layer 0
through Layer 2 to remain transparent to current cloud services
model. The proposed document identifies the initial set of
requirements to OCX, that can be run by NRENs, as a part of the
GÉANT network, or jointly, and provides suggestions about OCX
implementation. The proposed OCX concept will leverage the
existing Internet eXchange (IX) and GLIF Open Lightpath
Exchange (GOLE) solutions and practices, adding specific
functionality that will simplify inter-CSP and customer
infrastructure integration when supporting basic cloud services
provisioning models, in particular Trusted Third Party (TTP)
services to allow federated infrastructure and access control,
commonly used by NRENs. The paper also describes
trusted/secured topology exchange protocol and dynamic trust
establishment protocol as a part of the OCX services.
