OpenDaylight Summit: Pick and Choose

At the OpenDaylight (ODL) Summit, we got news about the development of its controller infrastructure. It’s important to remember several things about ODL:

  • It has a set of northbound APIs through a variety of methods such as REST. An example project is the Virtual Tenant Network, which NEC has contributed to ODL. The apps that are created to use the NB API directly deliver the value of the SDN system to end-users.
  • A set of southbound plug-ins enables interactions to data plane elements via different devices or protocols, such as Open vSwitch, or OpenFlow. This is the part that makes the system work with the real-world of devices.
  • There’s lots of infrastructure code in the middle, that is mostly hidden from end-users, but technically defines ODL’s architecture.
  • ODL isn’t a product per-se, but a set of projects under one umbrella. There are common components, of course, but many other elements are optional, due to the modular architecture. It’s possible for an end-user to download pieces of this open source project and construct their own ODL controller, but many choose to rely on a distribution that packages it for you. These create different flavors of ODL.

OpenDaylight Summit: NFV strong

153756157_jpgI attended the OpenDaylight (ODL) Summit last week, and saw progress, especially in the NFV area. Some of the early skeptics of the project seem to be taking a second look, and new members are joining the ODL project.

Looking Forward to OpenDaylight Summit

Posted: July 22, 2015   /   By: Dan Conde   /   Tags: Networking, OpenDaylight

153756157_jpgOpenDaylight (ODL) Summit is coming up on July 27th. There are many tutorials for users and app developers, as they had in the past. ODL is an open source SDN (software defined network) and NFV (network functions virtualization) platform project that requires collaboration from different members to design, implement, and test systems, so the process of creating this software as a community is critical. Of course, it’s interesting to hear stories of end-users deploying this software and of vendors basing their products on the platform.

Here are a few items to keep an eye on:

Major IT & Networking Vendors Collaborate on New OpenDaylight Initiative to Fend Off SDN Fragmentation

Posted: April 08, 2013   /   By: ESG   /   Tags: IT Infrastructure, Networking, software-defined networking, SDN, OpenFlow, OpenDaylight

SDN’s promise of dynamic, programmable networks to support new applications like VM mobility remain, but a plethora of competing vendors’ SDN marketing hype has been muddying the waters on defining SDN -its vision, roadmap, and deployment timescale. While small SDN islands already exist today, ‘plug and play’ type interoperability was unlikely despite the OpenFlow ‘protocol.' So by taking a page from the open Linux platform’s development, a flock of systems vendors have launched OpenDaylight to build an open SDN platform in a transparent and collaborative environment overseen by the non-profit Linux Foundation. Membership to the OpenDaylight project is open to those willing to donate software and engineering prowess to develop an open source SDN platform. Founding members include Big Switch Networks, Brocade, Cisco, Citrix, Ericsson, IBM, Juniper Networks, Microsoft, NEC, Red Hat, and VMware. Other initial contributors include Arista Networks, Dell, Fujitsu, HP, Intel, Nuage Networks, and PLUMgrid; most companies' preliminary contributions are outlined in the press release at www.opendaylight.org. Projects and donations include open controllers, protocol plug-ins, and switch device enhancements with a first code release expected 3Q13.

The service provider driven Open Networking Foundation (ONF) is doing a commendable job of advancing the principles, promise, and benefits of SDN, but the unexpected tsunami of interest in SDN, although welcomed, has led to an SDN bubble destined to pop. Allowing the market to decide on the best SDN solution isn’t necessarily the most expeditious or cost effective approach. Collaborative central planning within the SDN ecosystem could yield better results.
