Cisco network Cloud: New Possibilities
23 Jan 2010
● Interaction between “network clouds” demands standard level of the management providing interaction of networks and sharing of computing and communication resources, belonging to different owners.
As an example of such approach the level of the management which have been built in the software of an intermediate level (cloud middleware) or in expansion of report BGP (Border Gateway Protocol) can serve. Use of such reports as HMRR (Extensible Messaging and Presence Protocol), as the standard interface between networks of different operators will allow “network clouds” to use a miscellaneous uniform functions of giving of names and the availability control, and also uniform rules of the user access that, in turn, will promote creation of compatible services. For example, “the cloud 1″ can learn that in “a cloud 2″ it is possible to get access to a number of services (for example, to report SPARQL, language of inquiries RDF and service OWL) if the user observes certain requirements. Having received the answer from the second cloud, “the cloud 1″ checks, whether the user meets the given requirements, and defines how to switch this user on “a cloud 2″. Besides, “the cloud 1″ will know how to request, activate and cause the user services in “a cloud 2″ and how to transfer to this “cloud” the user requirements (tariffs and conditions SLA). Thus, the mobile user receiving e-mail through server Microsoft Exchange, can be switched on “a cloud 2″ without interruption in service and with preservation of initial conditions of the contract with the operator.
. ● Dynamic management of politicians at different levels is necessary for the appendices working in “a network cloud”, just as to the appendices working in the corporate environment. When the user by means of service cloud computing creates “a cloud” copy (cloud instance), it should define rules of high level (policy) for all resources which are a part of this copy.
