Software Application Support plus Upgrades provides customers with software upgrades and maintenance releases for Cisco Application Software, registered access to Cisco Connection Online (CCO) plus technical support for one year. Increasing complexity, high user expectations, rapid technological change, and global deployment present enormous challenges to manage this constant state of change and growth. To overcome these challenges, Cisco Systems offers its customers not only advanced networking devices and the Cisco IOS operating system, but a full range of software applications designed to ensure optimum network performance. Every year, Cisco makes a massive investment in software enhancements (feature additions) and software maintenance (bug fixes). This investment is in response to both new opportunities and new challenges as Cisco strives to innovate and lead the industry. Cisco software typically undergoes major revisions and feature upgrades at least once a year. Cisco's goal is to offer its customers unconditional access to these enhancements so that they never have to make a financial decision about upgrading their software. This policy ensures that their network is constantly up-to-date and that all avoidable problems are, in fact, avoided. Cisco's Software Application Support plus Upgrades (SASU) product ensures that you get the benefit of that investment. Cisco is able to respond quickly to changes in networking environments, providing low-cost, immediate software upgrades and updates to enhance and extend the life of the software.
