Performance Evaluation of Network Slicing for Aerial Vehicle Communications

Using 5G networks for flying vehicles is an opportunity to provide reliable connectivity while reducing cost and requirements on size, weight and power consumption. Network slicing is one feature which is particularly of interest. It enables a reliable aerial vehicle control slice independent from payload communication, such as video streaming to the ground. For the Unmanned Aerial Vehicle (UAV) use case, we rely on a 5G testbed that serves cars on an operational highway and trains on a parallel rail section. To test the effectiveness of network slicing, we show that the UAV control slice is unaffected by an overloaded UAV payload slice.Expósito García, A.; Hofmann, S.; Sous, C.; García, L.; Baltaci, A.; Bach, C.; Wellens, R....

COMPARISON OF p-CYCLE CONFIGURATION METHODS FOR DYNAMIC NETWORKS

Abstract: Dynamic optical networks which are protected by p-cycles can be operated by different p-cycle configuration methods. We compare the blocking probability of two dynamic p-cycle configuration approaches and one static p-cycle configuration approach (protected working capacity envelope). 1

Multidomain Optical Networks: Issues and Challenges

Today, many leading organizations are undertaking extensive research on a very broad range of new and evolving optical networking technologies. These efforts carry particular significance, especially in light of the “postbubble” dynamics of the optical networking market and have led to the investigation of various cost-efficient optical technologies. Today’s telecom carriers operate several independent optical domains based on diverse technologies, control solutions, standards, and protocols, making interdomain and intercarrier interworking extremely difficult. Standardized interworking across diverse multigranularity network interfaces, and interoperability across disparate vendor equipments and carrier domains are crucial to provisioning end-to-end services and achieving cost-efficient network operation. Needless to say, having an interoperable and standard control plane across multidomain optical networks can benefit carriers through the availability of a wide selection of network elements, platforms, and multiple vendor solutions resulting in faster deployment and reduced CAPEX and OPEX charges
