Software Defined Network (SDN) & Cisco Evolved Services Platform

Nowadays, the business is going to reduce the IT investments, and increase their core business. In the meantime, the demand of network services that the consumers want data, video, and other mobile services combine together is also increasing rapidly. Therefore, the internet service providers need to be responded the demand quickly and profitably, yet it also costs more money and time for integrating and developing new servers and extra services. Now, the companies need a solution that creates extensible and elastic capabilities to overcome these challenges, and cloud computing also the key for this.

The SDN is the major key for solving the type of challenges, and is the future of IT how to manage the network easily. SDN is stand for Software Defined Network which means managing the network services by higher layer/ software application (Programmable Network) via OpenFlow protocol. The overview of SDN can be seemed as three layers which are Infrastructure (Physical Network), Unified Platform (Controller) and Application (SDN Layer) from low to high.  To accomplish the communication between infrastructure layer and application layer is the unified platform which the OpenFlow protocol is the language it speaks.

Announced by Cisco News on Feb. 18th, the Cisco Evolved Services Platform has been released which is the key to make the network more extensible, elastic and open to SDN (Cisco ONE SP Architecture). The Cisco Evolved Services Platform allows applications to across many of domains and services easily. Imaging, only few clicks, you can easily deliver your commands manage the network to fit the demands and needs of the business less time and cost instead of re-configuring physical layers.

For me, I worked on Cisco devices in lab, and I know how frustrating every time to re-configure the devices (Not only for Cisco devices, but also for other brand of devices) to meet the different kind of requirements of needs. Basically, SDN is a great tool to reduce the cost and time for IT doing the routine tasks, changing network mapping, maintenance and integrating new systems to existed systems, and etc…

    I think the main advantage of SDN is its centralized programmable network. It makes it possible to adapt to the changing requirements automatically and dynamically.

    Cisco has quietly became a juggernaut in services platforms. I feel that you touched on that and was very clear and interesting.

    Very informative presentation. Cisco has always been a worldwide leader in networking transforming how people connect, and communicate and with its comprehensive ESP platform it looks like they’ve proven themselves yet again. Nice job!

    Software defined networking SDN allows network administrators to manage network services to a lower level of functionality where they make decisions about which directions the traffic is going in the network, and select the best path for the destination, maybe in a near future will simplify networking.
