China Unicom Deploys Caspian Media Controllers to Guarantee User Quality.

SAN JOSE, Calif. -- Caspian, the leading provider of multimedia traffic management solutions for IP and multi-protocol label switching (MPLS) networks, today announced that China Unicom, the world's third largest mobile telephone operator, is deploying Caspian's Media Controllers with OC-48 trunks across its country's backbone to manage multimedia network traffic by allocating bandwidth more efficiently and fairly. Caspian is the first company to apply a dynamic hierarchy of bandwidth management policies based on its Fair Use Policy Framework that China Unicom is leveraging to deliver superior service to over one million subscribers.

The China Unicom deployment marks the first time that Caspian solutions have been deployed in a mobile communications IP network to improve user quality while maximizing data throughput. With millions of Global System for Mobile Communication (GSM) and Code-Division Multiple Access (CDMA) subscribers, and a growing portfolio of innovative mobile voice and multimedia services, China Unicom can now apply and enforce IP traffic management policies that support QoS across its network with Caspian's Media Controllers.

"With Caspian, we can deliver exceptionally high-quality IP services and optimize bandwidth to allow for the continuing growth of new services over our existing network infrastructure," said Mr. Li, General Manager of China Unicom. "As a result, Caspian is saving us a lot of money while helping us to preserve the investment we have made in our network infrastructure."

"As the world's third largest mobile operator, China Unicom recognizes the need to deploy new services while maintaining high network quality," said Brad Wurtz, Caspian president and chief executive officer. "By combining the advantages of our Media Controllers with our Fair Use Policy Framework, we are making its voice network infrastructure more reliable and efficient, ensuring a high quality experience for China Unicom customers."
