We propose a survivable routing and resource assignment scheme with MPP and SRLG in VON to get less resources consumption and enough protection against physical failure. 29% reduction in resource consumption can be achieved.
We define k-content connectivity as the reachability of at least one content from any point of a data center network under concurrent k-1 failures. A flexible content placement algorithm is proposed to achieve k-content connectivity.
Based on the reasonable modeling of the spectrum consecutiveness around the node, the concept of node handling capacity is proposed which can effectively indicate the degree of spectrum fragmentation in flexible grid optical networks.
We propose two novel adaptive spectrum defragmentation algorithms in elastic optical networks by properly rerouting existing connections based on the evaluation of current network status, and numerical evaluation shown to be resource efficient.
Generalized Multi-Protocol Label Switching (GMPLS) based optical networks are viewed as a promising network infrastructure for the next generation network (NGN) development. By pre-configuring the resources of dynamic optical networks, we can reconstruct the physical topology, thus increase the number of direct routes between potentially heavily loaded physical node pairs and optimize the performance...
As an extension of the known light trail and light tree techniques, we explore the most possible general setting of time division multiplexing in circuit switched all optical networks. It will be shown that this technique improves the scalability and adaptability of all-optical networks without the need of expensive techniques like wavelength converters and burst switching or packet switching capable...
A novel multi-domain L1VPN provisioning architecture is proposed based on service plane of the adaptive multi-services provisioning platform. Moreover, the architecture we proposed was experimentally demonstrated in our AMSON testbed.
