SDN 101 – SDN & NFV introduction

SDN is most talked about terminology in networking world and destined to be game changer. Application & computing landscape has been changed over a period of time, with the adoption of cloud and virtualization network has increasingly become complex and extremely difficult to manage. SDN promise simplicity, agility and programmable network to meet the complex business requirements with faster time to market and at reduces cost by bringing automation.

At very high level SDN is the new way to manage the networks that decouples control plane and data plane and thus offer greater flexibility and centralized control using SDN brain (controller). SDN controller use openflow communication protocol to interact with forwarding plane of network devices such as router & switches.

The global Software Defined Networking Market size was valued at 2.46 Billion in 2016 and is expected to reach USD 54.41 Billion by 2022, at a Compound Annual Growth Rate (CAGR) of 71.4%

This course will help professionals to understand software defined networking, openflow, cloud computing concepts with OpenStack. This course also discuss NFV concepts with understanding on how x86 hardware can be leveraged to virtualized network functions.

Prerequisites: CloudSense 101 or equivalent certification is desired to attend this course with minimum 3 years of industry experience.

Course Objectives:

After completion of this course candidate will have idea about software defined networking, openflow, Cloud computing, various cloud deployment & service models, OpenStack components including nova, glance & neutron.

Who should attend? Network security consultant, Network architects, network managers, systems engineers staff who are responsible for planning, Implementing and deploying networks which may require SDN & NFV in future. Download Course Content
