- 10. Kiss “The Network” Goodbye!!! How about a “white-sheet” network with nodes exposing programmable control to 3 rd party code?

- Requirement Distribution of applications (data and business rules/logic) across an Intranet, Extranet and the Internet Consistent view of extended enterprise to customer Caching, Replication and Geographic proximity of data and business/rules logic to improve application performance Synchronization of completion of task performed by applications Automation of workflow (routing from one application to another) Challenge Enable connectivity between disparate applications Automate the workflow Connect with stovepipe applications outside of the enterprises Today’s Solution API Support Namespace management Protocol Conversion Session management Object level routing Caching of data and objects Load-balancing of data and objects Big Idea Distributed applications are supported by “distributing” the integration services to the points of entry into the network (not at a remote server) Integration services are implemented in the “network box” and hence are available to all entities attached to the network utility Voice Switch Analogy : Network becomes the “Virtual Tandem Switch”
