Youku is aimed to be the primary source of online video content for Chinese internet users across all internet-enabled devices. Their challenges are they need a rapid growth of its online audience and content library, combined with the need to deliver a high-quality streaming service at higher definitions. They chose Juniper Networks to overcome these challenges. They deployed to EX8216, EX4200, EX3200, EX2200 Ethernet switch and Junos operating system. The results of implementing Juniper Networks were simplified but highly reliable and cloud-ready data center network architecture enables Youku to scale capacity on an as-needed basis while keeping a lid on operational cost thanks to dramatically improved manageability.
