Dear all, Clouds are such a broad area. In addition to APIs, security and server technologies, there are many aspects of Network Technologies as well, which are essential to Clouds. There bound to be multiple IETF working groups, if established, to address variety of concrete network problems and solutions for Clouds. One of the Clouds application scenarios is Cloud Computing service, like Amazon's Elastic Compute Cloud (Amazon EC2), which allows users (clients) to create their own virtual servers and virtual subnets. There are many potential services which Cloud Computing services could offer to their clients. Here are just some examples of those services: - A client can request a group of virtual servers and their associated virtual subnet, - A client can specify policies among multiple subnets they purchased, - A client can specify preferred geographic locations for some of the virtual servers they purchased, - A client can specify redundancy criteria, like two virtual servers on two different physical servers or in two different locations, etc. In order to efficiently support those services, network has to support virtual subnet, i.e. one Layer 2 network spanning across multiple locations, in addition to large amount of hosts in Layer 2. It is possible for Cloud Computing service to have a network design that each virtual subnet is mapped one independent Layer 2 network. But this kind of design would require huge amount of administrative and planning work to properly partition servers, switches to appropriate Layer 2 network. The problem is that virtual servers and virtual subnets purchased by clients change all the time. It is a lot of administrative work to change Layer 2 network partition each time there is a client request. Having a large amount of virtual machines in one Layer 2 network can simplify some aspects of Cloud Computing service design and management. Therefore, we are recommending IETF to create a working group to develop solutions in this area. There is a Bar BOF scheduled at 78th IETF on Thurs (July 29) 11:30am ~1pm to review the problems and discuss potential solutions. I hope those of you who are interested in network problems for Clouds can come to this Bar BOF and contribute your ideas. http://trac.tools.ietf.org/bof/trac/wiki/BarBofsIETF78Arp222 Linda Dunbar _____ From: clouds-bounces@ietf.org [mailto:clouds-bounces@ietf.org] On Behalf Of Bhumip Khasnabish Sent: Monday, July 12, 2010 7:55 AM To: clouds@ietf.org Subject: [clouds] fwd: tentative agenda for Clouds bar BoF during IETF-78 inMaastricht Dear All, Here is a list of items for the IETF-78 Clouds bar BoF Survey of SDOs/WGSs -- Bhumip Clouds Ref.
