Fabric, SD‐WAN, vCPE, vRAN, vEPC

This chapter examines the main categories of products linked to software‐defined networking (SDN). The goal of SDN is to centralize the order that enables the distribution of the flows over all the fabric paths. The company CISCO took rather a long time to come out with its own SDN architecture, which it did in 2014. The VMware platform is essentially based on the virtualization of the NSX architecture. Brocade's solution offers flexibility and agility in the SDN architectures. Virtual machines carrying out the customer premises equipment are managed by the software‐defined wide area network controller. OpenContrail from Juniper is an open, simple and agile SDN solution that is able to automate and orchestrate the creation of virtual networks on demand. Virtual radio access network is an NFV application on the level of access network. Virtual evolved packet core is virtualized in one or several datacenters according to the network size and required multiplexing.
