Mar 21, 2007

SAN JOSE, CA, March 21, 2007 - Cisco Systems, Inc., (NASDAQ: CSCO) today announced it has completed the acquisition of privately-held Reactivity, Inc., of Redwood City, California. Reactivity is a leading XML (eXtensible Markup Language) gateway provider for organizations ranging from commercial enterprises to the Global 500.

Customers and major software providers are evolving their enterprise software architectures from a client-server paradigm to a service-oriented architecture. In addition, customers are deploying a variety of Web 2.0 capabilities that are collectively transforming the World Wide Web from a collection of relatively static web sites to a services rich computing platform.

The Reactivity acquisition demonstrates Cisco's commitment to the expanding Application Networking Services (ANS) Advanced Technology segment, which is an important part of Cisco's Service-Oriented Network Architecture (SONA) strategy and vision. Reactivity complements and extends the capability of Cisco's ANS portfolio for these emerging application architectures.

With the close of the transaction, the Reactivity team and product portfolio are now integrated into the Cisco's Datacenter Switching and Security Technology Group (DSSTG), reporting into Jayshree Ullal, Senior Vice President.
