Cisco Wide Area Application Services (WAAS) software on Cisco Integrated Services Routers Generation 2 (ISR G2) provides router-integrated, on-demand WAN optimization & application acceleration for branch offices. Cisco WAAS has been designed since inception to provide the highest degree of integration with Cisco routing solutions. Cisco WAAS offers the option to integrate physically with first- & second-generation Cisco ISRs. The Cisco Services Ready Engine (SRE) Modules on the ISR G2 platform, which decouple software services from the underlying hardware, can deliver WAN optimization as an on-demand service as required for business objectives & IT budget. This approach allows organizations to make better use of existing investments while offering business agility.
