Biography

Zheng Cai is a fifth-year PhD student in Department of Computer Science of Rice University. He received his B.S. from College of Computer Science and Technology at Zhejiang University. His research interests mainly lie in computer network and system. His advisor is Prof. Eugene Ng.

Research Projects

• Maestro -- Maestro is an "operating system" for orchestrating network control applications. Maestro provides interfaces for implementing modular network control applications to access and modify state of the network, and coordinate their interactions. Maestro is a platform for achieving automatic and programmatic network control functions using these modularized applications. Maestro is developed in Java, so it is highly portable to various operating systems and architectures. Furthermore, Maestro is multi-threaded to take full advantage of multi-core processors. For OpenFlow networks, on an 8 core system, Maestro has been demonstrated to route over 600,000 flows per second.

• 100x100 -- In the 100x100 project, we are conducting the basic research and developing the blueprint designs that will guide decision-makers in the construction of a next generation network that is dependable and secure; understandable to users and operators; and both economical and scalable.

• The 4D Architecture for Network Control and Management -- While Internet Protocol (IP) has been a runaway success, today's IP networks are difficult to manage well. Operations costs are high and yet network reliability remains low. Our research begins from the observation that the root cause of these problems is IP's current management and control planes, which distribute vital state and control functions across multiple systems.
