The IESG has approved the following document: - 'A PCE-based Architecture for Application-based Network Operations' (draft-farrkingel-pce-abno-architecture-16.txt) as Informational RFC This document has been reviewed in the IETF but is not the product of an IETF Working Group. The IESG contact person is Alia Atlas. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-farrkingel-pce-abno-architecture/ Technical Summary Services such as content distribution, distributed databases, or inter-data center connectivity place a set of new requirements on the operation of networks. They need on-demand and application-specific reservation of network connectivity, reliability, and resources (such as bandwidth) in a variety of network applications (such as point-to- point connectivity, network virtualization, or mobile back-haul) and in a range of network technologies from packet (IP/MPLS) down to optical. An environment that operates to meet this type of requirement is said to have Application-Based Network Operations (ABNO). ABNO brings together many existing technologies for gathering information about the resources available in a network, for consideration of topologies and how those topologies map to underlying network resources, for requesting path computation, and for provisioning or reserving network resources. Thus, ABNO may be seen as the use of a toolbox of existing components enhanced with a few new elements. The key component within an ABNO is the Path Computation Element (PCE), which can be used for computing paths and is further extended to provide policy enforcement capabilities for ABNO. This document describes an architecture and framework for ABNO showing how these components fit together. It provides a cookbook of existing technologies to satisfy the architecture and meet the needs of the applications. Working Group Summary This document is not the product of any IETF working group. There is currently no working group chartered to work on this topic. However, the document has been widely circulated for review with focus in the PCE, ALTO, and OPSAWG. Notification of the document with a request for review was also sent to the I2RS and RTGWG working groups. The SDNRG of the IRTF has had this work presented at several IETF meetings. Document Quality There are currently believed to be two implementations of network management packages in operators' research labs that are based on the architectural model described here. A further implementation is rumored to be planned by a third network operator. Although the operators have not been publically forthcoming about their implementations, some information can be found at: http://www.vlopezalvarez.com/Profesional/Publications/Conferences/2014_OFC_1.pdf http://www.infinera.com/pdfs/misc/Infinera-Telefonica_SDN_Demo.pdf https://www.fi-athens.eu/sites/default/files/presentations/ABNO.pdf http://www.cttc.es/publication/experimental-assessment-of-abno-based-network-orchestration-of-end-to-end-multi-layer-opsocs-provisioning-across-sdnopenflow-and-gmplspce-control-domains/ Personnel Quintin Zhao <quintin.zhao@huawei.com> is the Document Shepherd.
