Hi All, Please find a new version of the ABNO Architecture draft:
http://tools.ietf.org/html/draft-farrkingel-pce-abno-architecture-02 Updates include: - Discussion on the LSP database and the applicability of other databases. - Further description of the VNTM. - New use case (GCO - Thanks to Quintin Zhao). - Some new section placeholders (ALTO Server, Survivability and Redundancy) - Various nits and readability updates. As always, thanks for your attention and comments. Br, Adrian and Dan. -----Original Message----- From: [email protected] [mailto:[email protected]] Sent: 19 January 2013 20:14 To: [email protected] Cc: [email protected] Subject: New Version Notification for draft-farrkingel-pce-abno-architecture-02.txt A new version of I-D, draft-farrkingel-pce-abno-architecture-02.txt has been successfully submitted by Adrian Farrel and posted to the IETF repository. Filename: draft-farrkingel-pce-abno-architecture Revision: 02 Title: A PCE-based Architecture for Application-based Network Operations Creation date: 2013-01-19 WG ID: Individual Submission Number of pages: 38 URL: http://www.ietf.org/internet-drafts/draft-farrkingel-pce-abno-architecture-02.txt Status: http://datatracker.ietf.org/doc/draft-farrkingel-pce-abno-architecture Htmlized: http://tools.ietf.org/html/draft-farrkingel-pce-abno-architecture-02 Diff: http://www.ietf.org/rfcdiff?url2=draft-farrkingel-pce-abno-architecture-02 Abstract: 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 backhaul) 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 several 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.
