"Generation Free Platform," Technology for the Dependable Network Platform
Takashi Yoshikawa, Kami Nobuharu · NEC technical journal · 2006
Network equipments must have high availability in order to compose a node of the dependable network. We have developed a conceptual prototype of the dependable system-platform named the Generation-Free Platform. Some technologies are installed and operate together to demonstrate reliable and scalable service deployment over the generation of services and technologies. The long-distance and protocol-free connectivity of optical interconnects enable us to configure a redundant group over plural chassis. Then the automatic availability management framework allocates resources for a certain service on the redundant resources. In that process, the physical information such as location of each resources, shared risk group, and failure rate is considered. The evaluation result of a prototype system shows the proposed framework achieves no complete system down unless multiple-point failure case. This corresponds to the same level of reliability as legacy manual risk management while the resource utilization efficiency is twice as high.
