23. 23 Restricted to Nortel Networks Internal Review Value Proposition of the Application Switch Distributed applications are supported by “integration services” at the points of entry into the network —Application Switching occurs at the network entry as opposed to a remote server resulting in better application performance Integration services are available to all all entities attached to the network utility —Application developers can focus on business logic and data as opposed to configuring networking functions in the servers Network-switching functions and application services functions are closely coupled —Application switching can gain the same performance levels as the networking gear
