In section 4.5 "Control Plane Overlay Networking Work Areas" a back-end "oracle" responsible
for distributing and maintaining the mapping information for the overlay system is mentioned. I personally think, it would be a better approach to use a more network related term instead of "oracle", e.g. mapping system or mapping information system. >>> <[email protected]> 07.02.13 15.20 Uhr >>> A New Internet-Draft is available from the on-line Internet-Drafts directories.

Title : Problem Statement: Overlays for Network Virtualization Author(s) : Thomas Narten Eric Gray David Black Dinesh Dutt Luyuan Fang Lawrence Kreeger Maria Napierala Murari Sridharan Filename : draft-ietf-nvo3-overlay-problem-statement-02.txt Pages : 23 Date : 2013-02-07 Abstract: This document describes issues associated with providing multi- tenancy in large data center networks and how these issues may be addressed using an overlay-based network virtualization approach. A key multi-tenancy requirement is traffic isolation, so that one tenant's traffic is not visible to any other tenant. Another requirement is address space isolation, so that different tenants can use the same address space within different virtual networks. Traffic and address space isolation is achieved by assigning one or more virtual networks to each tenant, where traffic within a virtual network can only cross into another virtual network in a controlled fashion (e.g., via a configured router and/or a security gateway). Additional functionality is required to provision virtual networks, associating a virtual machine's network interface(s) with the appropriate virtual network, and maintaining that association as the virtual machine is activated, migrated and/or deactivated. Use of an overlay-based approach enables scalable deployment on large network infrastructures.
