Main CCNS Topics in IETF84


NVO3 (Network Virtualization Overlays)


Support for multi
-
tenancy has become a core requirement of data centers (DCs), especially in
the context of data centers supporting virtualized hosts known as virtual machines (VMs)


NVO3 WG will investigate the interconnection of the DC VPNs and their tenants with non
-
NVO3 IP network(s) to determine if any specific work is needed

SDN RG (Software Defined Networking Research Group)


SDNRG provides a forum for researchers to investigate key and interesting
problems in the Software Defined Networking field. It investigates SDN from
various perspectives with the goal of identifying the approaches that can be
defined, deployed and used in the near term as well identifying future
research challenges


Key areas of interest include solution scalability, abstractions, and
programming languages and paradigms particularly useful in the context of
SDN

SCIM (System for Cross
-
domain Identity Management)


SCIM working group will standardize methods for creating, reading, searching,
modifying, and deleting user identities and identity
-
related objects across
administrative domains, with the goal of simplifying common tasks related to
user identity management in services and applications

Key highlights of NVO3


Current foci of NVO3 are requirements and framework
drafts


Virtual machine (VM) mobility, data plane, control plane,
and security framework drafts also needs to be revised and
updated


Too many drafts are there and we need some convergence



Next steps for NVO3


Update the Framework, Requirements, VM mobility and
Interconnection, and Cloud Access/Services drafts

Too many Definitions for SDN … Needs some converge…



In SDN, just Opening the interface between the Controller and Forwarding planes is not
enough


It is also Required to develop deployable new applications that can run on top of SDN, including
dynamic access control, server load balancing, energy
-
efficient networking, and seamless client
mobility and virtual
-
machine migration, …



New paradigms are needed in designing


Switches and APIs that offer greater flexibility without compromising performance,


Software platform for the control and management of SDNs,


Low
-
barrier for creating, testing, and evaluating new applications, and


Transition an existing network to SDN, and interoperating SDN with existing protocols and devices.

be main usage of SDN

Key highlights of SCIM


XML may not be very popular, JSON has been voted in for
ID scheme development/finalization


There is a need to develop SCIM use case drafts


Security and Transport issue need to be considered in the
SCIM mechanism before and during the development



Next Steps for SCIM


Discuss the revised drafts with WG chairs


Publish the revised draft in Sept./Oct. 2012


Present the updated drafts during IETF85 mtg.
