Aiming at providing united control of multi-domain optical networks orchestration, we design the Federated Platform based on Open Network Operating System (ONOS). Our implementation includes adding and extending modules in ONOS to provide the global view of multi-domain networks and support cross-domain end-to-end services by communicating with the individual domain controllers through RESTCONF protocol...
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.
The flow aggregation scheme which aggregates a large number of finer-grained services into one large flow can save transceivers and improve spectrum efficiency. It ensures that all services in the aggregated flow have a same routing. Moreover, the spectrum allocated to all finer-grained services in the aggregated flow is continuous. Compared with independent transmission scheme which conducts the...
In this paper, we propose a light-tree based multicast flow aggregation (LT-MFA) scheme which can achieve the cost-efficient multicast service provisioning in elastic optical datacenter networks (EDONs). Moreover, a user-cover ratio based aggregation strategy is proposed for the LT-MFA scheme. An Integer Linear Program (ILP) model and a heuristic algorithm are developed to realize the LT-MFA scheme...
In this paper, we develop two joint routing and resource allocation algorithms for stealth and ordinary services in optical networks. The transmission of stealth service needs to be hidden in ordinary services to achieve a better performance in privacy. Two heuristic algorithms construct paths for stealth and ordinary services base on the different routing methods. The proposed algorithms improve...
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...
In this paper, we study the problem of survivable virtual optical network (VON) mapping against single link failure with shared backup path protection (SBPP) in elastic optical networks. We formulate this problem with an integer linear programming (ILP) model to minimize the resource consumption of both working and backup paths. A different dynamic cost model (DDCM) for each sharable frequency slot...
