The fifth generation of mobile communications is anticipated to open up innovation opportunities for new industries such as vertical markets. However, these verticals originate myriad use cases with diverging requirements that future 5G networks have efficiently support. Network slicing may be a natural solution simultaneously accommodate, over common network infrastructure, the wide range services vertical- specific will demand. In this article, we present concept, particular focus on its...
Quantum computers will change the cryptographic panorama. A technology once believed to lay far away into future is increasingly closer real world applications. break algorithms used in our public key infrastructure and exchange protocols, forcing a complete retooling of cryptography as we know it. Key distribution physical layer immune quantum or classical computational threats. However, it requires substrate, optical fiber has been usual choice. Most time just point link for exclusive...
Abstract Current quantum key distribution (QKD) networks focus almost exclusively on transporting secret keys at the highest possible rate. Consequently, they are built as mostly fixed, ad hoc, logically, and physically isolated infrastructures designed to avoid any penalty channel. This architecture is neither scalable nor cost-effective future, real-world deployments will differ considerably. The structure of MadQCI QKD network presented here based disaggregated components modern paradigms...
Operators are challenged by the new cloud services, which can modify current traffic pattern. This talk presents Telefonica I+D view on evolution towards a transport network ready to support services. It explains reasons why networks not efficiently design for environment and it describes architecture cloud-ready network. To show feasibility of such network, experimental validations presented concepts
Next-generation systems are anticipated to be digital platforms supporting innovative services with rapidly changing traffic patterns. To cope this dynamicity in a cost-efficient manner, operators need advanced service management capabilities such as those provided by NFV. NFV enables scale network higher granularity and agility than today. end, automation is key. In search of automation, ETSI has defined reference framework that makes use model-driven templates called NSDs operate services....
Network slicing is a powerful paradigm for network operators to support use cases with widely diverse requirements atop common infrastructure. As 5G standards are completed, and commercial solutions mature, need start thinking about how integrate capabilities in their assets, so that customer-facing can be made available portfolio. This integration is, however, not an easy task, due the heterogeneity of assets typically exist carrier networks. In this regard, networks may consist number...
Machine Learning (ML) technologies applied to Cybersecurity, especially in the area of network cyber threat detection, are a promising choice, but they require additional research applicability wide range available algorithms. Such algorithms usually training using good-quality and quantitatively significant datasets, which rarely publicly available. To this end, paper we describe novel experimental framework, that call Mouseworld, combines NFV SDN create an environment able (1) blend...

Quantum Communications is a field that promises advances in cryptography, quantum computing and clock synchronisation, among other potential applications. However, communication based on phenomena requires an extreme level of isolation from external disturbances, making the transmission signals together with classical ones difficult. A range techniques has been tested to introduce communications already deployed optical networks which also carry legacy traffic. This comes challenges, not...
We present a setup for testing CV- and DV-QKD technology coexistence over production network. demonstrate multi-technology, multiband operation of QKD systems working both separately in trusted-node configuration intra- inter-domain applications.
The essential propellant for any closed-loop management mechanism is data related to the managed entity. While this a general evidence, it becomes even more true when dealing with advanced systems like ones supported by Artificial Intelligence (AI), as they require trustworthy, up-to-date and steady flow of state be applicable. Modern network infrastructures provide vast amount disparate sources, especially in multi-domain scenarios considered ETSI Industry Specification Group (ISG) Zero...
