In recent years, data centers have be built for online applications, such as web search, e-mails, web 2.0, on-line gaming, etc. In this paper, the authors present C3Cube, a new network architecture specifically designed for modular data centers. C3Cube is server-centric network structure, composed of servers with multiple network ports and mini-switches. The logical construction of C3Cube is Cube-Connected Circle. A distribution routing protocol is running on each server. Their simulations demonstrate that C3Cube is fault-tolerant, and C3Cube shows graceful performance degradation as link, server and/or switch failure ratio increase.
