How Software Defined Wide Area Networking (SD-WAN) Provides Reliable Voice and Video Services Over the Internet
By Jason Gintert, Wan Dynamics
For as long as organizations have tried to make real-time services like voice or video work over Internet Protocol (IP) network pipes, there have been very basic requirements in order to make said services operate effectively. The first requirement for these sensitive applications was a dedicated, business class network line to carry this traffic. A business class circuit was paramount to reliability and uptime required for crucial services like voice or video. This type of network access has low latency characteristics which keeps the amount of time it takes to forward the voice traffic low so that conversations are not made off kilter by long delays.
Network Slicing and Blockchain to Support the Transformation of Connectivity Services in the Manufacturing Industry
By Nicolas Bihannic, Orange Labs; Thierry Lejkin, Orange Labs; Isabelle Finkler, Orange Business Services and Alexis Frerejean, Orange Business Services
In the 3GPP vision, “network slicing enables the operator to create networks customized to provide optimized solutions for different market scenarios which demand diverse requirements, e.g. in the areas of functionality, performance and isolation” . Network slicing can be fully implemented with the combination of three properties: network softwarization, a better granularity in the definition of functions composing the 5G system, and a larger distribution of datacenters especially at the edge of networks.
The Diamond Approach for SDN Security
By Angelo Liguori, Huawei, German Research Center; and Marcel Winandy, Huawei, German Research Center
Software Defined Networking (SDN) has attracted a lot of interest in both academia and industry, and it has started to be adopted in real system implementations. SDN emerged as a new concept with the intent of enabling central programmability of the network, although it can be traced back to earlier concepts like Active Networks, Network Control Point, and Routing Control Platform [1,2,3]. SDN is based on the idea of decoupling the control plane from the data plane, introducing a logically centralized control with open interfaces, and providing an API on abstractions of the network elements to program their forwarding behaviour . SDN opens new opportunities for telecommunications and network operators as well as enterprise networks by providing effective means for fast infrastructure provisioning and dynamic reconfiguration of networks.
