At the recently concluded IEEE P2302 Inter-Cloud Interoperability Working Group meeting, it was noted that there are many SDOs working on cloud computing whitepapers, standards and specifications. The P2302 WG is interested in those that are addressing inter-cloud aspects including communications, policy, protocols, or security for potential collaboration. Inter-cloud scenarios include: public to public, public to private (and vice-versa), private to private cloud interconnections for both computing and storage.
Here is an incomplete list of Cloud Computing SDOs along with their output documents and work in progress:

In June 2006 ETSI technical committee GRID was created and held its first meeting in September.
TC GRID’s task is to address issues associated with the convergence of Information Technology (IT) and telecommunications, paying particular attention initially to the lack of interoperable Grid solutions in situations which involve contributions from both the IT and telecommunications industries.
In 2008, TC GRID undertook a survey of existing stakeholders in the Grid domain, for which the European Commission (EC) provided financial support. A test frame for Grid standards is being developed in collaboration with ETSI’s Centre for Testing & Interoperability (CTI).
There is also an increasing interest in addressing the convergence between ETSI technical committees GRID and TISPAN (Telecommunication and Internet converged Services and Protocols for Advanced Networking).

Virtual Network Research Group (VNRG)
In the network community, “Virtual Networks” is a very broad term, including running multiple wavelengths over a fiber, MPLS, virtual routers, and overlay systems. VN technologies are widely used in parts of the Internet and other IP-based networks, but the community lacks a common understanding of the impact of virtualized networks on IP networking, or how VNs are best utilized. As a result, virtualization has been difficult to integrate across various systems, such as network operators, vendors, service providers and testbed providers (e.g., GENI, FEDERICA, etc).
One current challenge with existing VN systems is the development of incompatible or competing networking techniques in the Internet, causing deployment issues in the future (or even now). For instance, there are numerous ways to virtualize routers and their internal resources (e.g., multiple, isolated routing and forwarding tables) and to virtualize core networks (e.g. MPLS, LISP), but the end host virtualization has not been addressed (e.g., beyond the need for virtual interfaces). Few virtual network systems allow a particular virtual machine in an end host to control its attachment to a specific private network. End host virtualization architecture also determines whether virtualization is per virtual machine, per process, or per connection – and this difference can determine exactly how the end host can participate in VNs. Similar issues arise for virtual services, virtual links, etc.
The VNRG builds on the efforts of a number of IETF WGs, including encapsulated subnets (LISP at layer 3, TRILL at layer 2), subnet virtualization (PPVPN, L3VPN, L2VPN), and aspects of managing virtual components (VRRP), as well as some work in more general areas, notably on tunnels (INTAREA). A side effect of the VNRG is to help place these contributions in a broader context.
The Virtual Networks Research Group (VNRG) will consider the whole system of a VN and not only single components or a limited set of components; we will identify architectural challenges resulting from VNs, addressing network management of VNs, and exploring emerging technological and implementation issues.
Initial set of work items:
- common parts of VN architectures
- common problems/challenges in VN
- descriptions of appropriate uses
- some solutions (per-problem perhaps)
Alliiance for Telecommunications Industry Standardization (ATIS)

The ITU FG Cloud will contribute with the telecommunication aspects, i.e., the transport via telecommunications networks, security aspects of telecommunications, service requirements, etc., in order to support services/applications of “cloud computing” making use of telecommunication networks; specifically:
- identify potential impacts on standards development and priorities for standards needed to promote and facilitate telecommunication/ICT support for cloud computing
- investigate the need for future study items for fixed and mobile networks in the scope of ITU-T
- analyze which components would benefit most from interoperability and standardization
- familiarize ITU-T and standardization communities with emerging attributes and challenges of telecommunication/ICT support for cloud computing
- analyze the rate of change for cloud computing attributes, functions and features for the purpose of assessing the appropriate timing of standardization of telecommunication/ICT in support of cloud computing
The Focus Group will collaborate with worldwide cloud computing communities (e.g., research institutes, forums, academia) including other SDOs and consortia.
ITU-T TSAG is the parent group of this Focus Group.
