Distributed Management Task Force Cloud Management Standards Working to Address Management Interoperability for Cloud Systems Technologies like cloud computing and virtualization are rapidly being adopted by enterprise IT managers to better deliver services to their customers, lower IT costs and improve operational efficiencies. DMTF's Cloud Management Initiative is focused on developing interoperable cloud infrastructure management standards and promoting adoption of those standards in the industry. Cloud Working Groups DMTF’s Cloud Management Initiative is promoting the work of the Cloud Management Work Group, the Cloud Auditing Data Federation Working Group, the System Virtualization, Partitioning, Clustering Working Group and the Software Entitlement Working Group.

Useful mininet setups | SDN Hub Mininet is a network emulation platform that is very useful to test SDN applications that you build. It can support different types of topologies. Here we showcase three popular configurations that will be helpful for testing. 1. Single switch Following command spawns a single switch with 3 hosts attached to it. $ sudo mn --arp --topo single,3 --mac --switch ovsk --controller remote In the above command, there are some important keywords worth paying attention to: –mac: Auto set MAC addresses–arp: Populate static ARP entries of each host in each other–switch: ovsk refers to kernel mode OVS–controller: remote controller can take IP address and port number as options You can now perform ping between hosts h1 and h2 using command h1 ping h2. 2. Following command spawns two switches connected to each other with a link and has one host on each switch. $ sudo mn --topo linear --switch ovsk --controller remote 3. Following command spawns a switch that has 3 servers and 1 client connected to it.
OpenFlow - Enabling Innovation in Your Network FAQ: What is OpenFlow and why is it needed? Frequently asked questions about the OpenFlow protocol and its potential. What is OpenFlow? OpenFlow is a programmable network protocol designed to manage and direct traffic among routers and switches from various vendors. It separates the programming of routers and switches from underlying hardware. It is the result of a six-year research collaboration between Stanford University and the University of California at Berkeley. IN THE SPOTLIGHT: OpenFlow gets wide backing How does OpenFlow work? The technology consists of three parts: flow tables installed on switches, a controller and a proprietary OpenFlow protocol for the controller to talk securely with switches. Why is OpenFlow needed? Vendors offer varying degrees of user programmability on their routers and switches. Wasn't MPLS designed to do this? Yes, MPLS is a traffic management and engineering technique. When will OpenFlow be available? A limited number of vendors are offering it now. Learn more about this topic
What is software-defined networking (SDN)? - Definition from WhatIs.com Software-defined networking (SDN) is an umbrella term encompassing several kinds of network technology aimed at making the network as agile and flexible as the virtualized server and storage infrastructure of the modern data center. The goal of SDN is to allow network engineers and administrators to respond quickly to changing business requirements. In a software-defined network, a network administrator can shape traffic from a centralized control console without having to touch individual switches, and can deliver services to wherever they are needed in the network, without regard to what specific devices a server or other hardware components are connected to.

NOX | An OpenFlow Controller OpenDaylight Application Developers' Tutorial | SDN Hub This tutorial is intended for developers new to SDN application development with OpenDaylight. We have come a long way from the earlier version of this tutorial to focus on MD-SAL, and Karaf in this tutorial. While OpenDaylight is not simply an OpenFlow controller, OpenFlow continues to be a popular south-bound and we use this in this tutorial to introduce the platform. An introductory presentation is available at slideshare. 1. To get started, download and set up the SDN Hub Tutorial VM in Virtualbox or VMware. The tutorial application that we will work with is located in /home/ubuntu/SDNHub_OpenDaylight_tutorial directory. Before we start, we recommend you run the following commands to update the tutorial code, which is available at ubuntu@sdnhubvm:~$ cd SDNHub_Opendaylight_Tutorial ubuntu@sdnhubvm:~$ git pull --rebase 2. OpenDayLight uses the following software tools/paradigms. 2.1 Maven and project building 2.3 Config subsystem 3.
Software Defined Virtual Networks | NIST Background Data networks have enabled extraordinary growth in capabilities such as email, the web, and social media; and today form the technical basis for our information-centric economy[1]. However, current network architectures and processes for technical evolution cannot support the complexity and pace innovation in emerging applications such as Virtualized / Cloud Computing, Internet of Things, ubiquitous Mobile Computing and Big Data Analytics. Today’s industry norm of deploying special purpose, fixed-function hardware appliances (e.g., routers, switches, firewalls, load balancers) that implement standardized protocols no longer scales with the required pace of innovation for new services, nor the economics of modern virtualized computing. In today’s networking industry, these barriers to innovation result in lead times of years to design and develop new network services and require tremendous capital and operational expenses to deploy and operate new network functions.
