We study the problem of dynamic content replacement in terms of network state variation in elastic optical datacenter networks. A dynamic content replacement scheme is proposed to minimize spectrum consumption, blocking probability and network latency.
We study the problem of joint spectrum and storage resource backup (JSSRB) to improve the survivability of elastic optical datacenter networks (EODNs) for cloud services. An ILP model and heuristic algorithms are developed. Simulation results show that JSSRB can effectively improve the survivability and spectrum efficiency of EODNs.
Disaster, natural or man-made, is the main threaten of survivability and reliability of networks. The development of content connectivity provides a new way of protection against disaster to ensure the reliability of network service/content. This paper focuses on shared backup path protection based on content connectivity against disaster in the context of elastic optical datacenter networks. In this...
