Software defined flow-mapping for scaling virtualized network functions
Sharon Barkai, Randy Howard Katz, Dino Farinacci, David Meyer · 2013
Network functions such as subscriber-management, content-optimization, security and quality of service, are typically delivered using proprietary hardware appliances embedded into the network as turn-key service-nodes. Next generation functions are being implemented as pure software instances running on standard servers - unbundled components of capacity and functionality. Location-Identity-Separation Overlays enable SDN flow-mapping to dynamically assemble these components to whole solutions by steering the right traffic in the right sequence, of mobile users, to elastic apps & functions.
