The wide coverage of satellite networks and the large bandwidth terrestrial have led to an increasing research on integration two (ISTN) for complementary advantages. However, most researches routing mainly focus internal network. Due point-to-area channel characteristics between satellites ground stations, heterogeneity ISTN has increased, which makes that algorithm traditional cannot be applied end-to-end ISTN. Meanwhile, data flows with elastic quality service attribute make pre-assign...
We propose a proactive dynamic network slicing scheme that utilizes deep-learning based short-term traffic prediction approach for 5G transport networks. The demonstration shows utilization efficiency improvement from 46.33% to 71.53% under the evaluated scenario.

We proposed a multi-tenant slicing scheme with multi-domain, multi-layer and multivendor (M3) features. The experimental demonstration shows the created modified around in 353ms 150ms, hybrid resource isolation has offered.
With the rapid development of network science and technology, experiment course plays a more important role in higher education. However, experiments colleges universities are low efficiency poor flexibility because limitations different operation methods, device types, vendors location distribution. This paper describes platform based on software-defined to solve these for educational uses. Combined with characteristics SDN, we divide platform's architecture into management layer, control...
With the increasing demand of network slices in vertical industries, slice resource provisioning transport networks has encountered two challenges, one is efficient presence traffic uncertainty slices, and another flexible isolation for customizable needs. In this paper, we propose an innovative hybrid model to support any customized from complete full sharing, solve problem named Hybrid Slicing Minimum Bandwidth (HSMB) by considering prediction error mitigate negative impact proposed model....
A topology reconstructed networking algorithm is proposed to find the minimal set of optical inter-satellite links under guarantee quality service. Simulation results show that nearly 30% could be saved.
We designed and implemented a dynamic simulation platform for software defined optical satellite networking. It can simulate all nodes in network on one computer. refresh the real time highly complex environment, including changes connection between caused by periodic motion of link quality, etc. In addition, apply other algorithms so that is practical scalable. also conducted test small constellation this platform. The experimental results obtained are line with expectations reflects capabilities
