amed Network Service Chaining [NSC] is currently collecting drafts in its BoF (birds of a feather) stage which includes drafts proposing formalized packet headers for expressing service context and metadata as well as the need for a standardized generic service control plane. Standardized (ETSI) NFV: ISG Works Use Cases: Initial application field and technical challenges. Requirements: Technical and business requirements for an NFV framework, including service models. Architectural Framework: High level functional architectural and design idea for VNFs and underlying virtualization infrastructure. Terminology: Repository for common terms used within ETSI NFV documents. Use Cases: Initial application fields: Four main service-oriented use cases. Construction of NFV infrastructure as a Service. VNF implementation as a Service. Virtual Network Platform construction as a Service.

Virtualizing Network Platform Current service provider networks have evolved into a collection of purpose- designed, integrated elements or platforms e.g. the fundamental design of a core routing platform is to forward packets at an extremely high speed and low latency with packaging sensitive to physical footprint, power consumption, and associated heat. Without an entirely different set of forwarding blades and service blades, the placement of this platform at the network/provider edge where a tradeoff is required between forwarding rate, session state management, protocol session scale, and other services may be difficult. Some vendors have gained proficiencies in packaging certain types of platforms over time. The most common examples are the Broadband Network Gateway and Evolv
