About the Cisco Service Modules
Cisco Internal Service Module-Services Ready Engine (Cisco ISM-SRE) and Cisco Service
Module-Services Ready Engine (Cisco SM-SRE) hosted by the Cisco ISR G2 have their own processors,
storage, network interfaces, and memory that operate independently of the host router resources. This
configuration helps to ensure maximum concurrent routing and application performance. A
service-ready deployment model enables branch-office applications to be provisioned remotely on the
modules at any time. The Cisco ISM-SRE and Cisco SM-SRE also support Cisco Software Licensing
(CSL) and Pay-as-you-Grow (PAY-GO) features.
