iWAG Scalability and Performance
The infrastructure of a service provider must be capable of supporting the services that an enterprise customer
or Internet service provider (ISP) wants to offer its subscribers. The service provider must also be able to
scale up to an expanding subscriber base. You can configure IWAG on the Cisco ASR1000 Series Routers
for high scalability and performance.
