Greetings my dear cyber-readers!
In this new opportunity, let them talk a little about Networks and Free Software making mention of a promising Software that is becoming more popular and used worldwide every day, this is OpenDayLight.
OpenDayLight It is a project of Open Source (opensource) which aims to accelerate and increase the dissemination of innovation in the design and implementation of an open and transparent standard of Software Defined Networks (RDS), i.e. Software-Defined Networking (SDN). Currently the project has the support of large and recognized companies such as:
- network,
- brocade,
- Cisco,
- Citrix,
- Ericsson,
- IBM,
- JuniperNetworks,
- Microsoft,
- NEC,
- RedHat,
- VMware
And recently they have released their latest version of the program called beryllium.
OpenDayLight pretends to emulate what Hadoop has made in the market of BigData and what OpenStack does in the Cloud Computing. In other words, to become an open platform that all companies use, preventing proprietary (proprietary) applications (programs) from restricting market growth and at the same time reducing development costs.
La virtualization and cloud In recent years they have been highly innovative technologies, but now the turn is for networks, which have remained static and hardware-based, until now. Which began to change with the arrival of Software Defined Networking (RDS) - Software Defined Networking (SDN), which promise greater scalability, flexibility, and programmability by removing much of the network intelligence from switches and routers and putting it in software-based drivers.
OpenDayLight intends to become a common and open SDN platform I incorporated areas such as the controller platform or the protocols of the network applications, the user interfaces, the virtual switches or the physical interfaces of the device.
The main advantage of this proposal is that it eliminates the adoption barriers, as some organizations do not want to commit to a specific manufacturer that ends up blocking their future. Being a common platform, companies will be able to opt for technologies from diverse manufacturers that will be interoperable.
Specific Big Switch Networks, Brocade, Cisco, Citrix, Ericsson, IBM, Juniper Networks, Microsoft, NEC, RedHat, and VMware are the members Platinum y Gold (main founders) of the project, who donate software and engineering resources for this Proyect Open Source and will help define the open SDN platform, as officially reported.
In definitive accounts OpenDayLight is a OpenFlow controller, which in turn is a protocol that allows a server to tell network switches where to send packets. In each traditional network, Each switch has proprietary (proprietary) software that specifies the rules to follow (what to do). With OpenFlow packet migration decisions are centralized so the network can be schedule independent of individual switches and data center equipment.

And what really are Software Defined Networks?
All the SDN are a way of approaching networking in which take control a software application called a driver and not hardware network network.
When a package arrives at a switch In a traditional network, the rules that are integrated into the firmware private and closed switch they tell the same where to transport the package. He Switch it sends each packet to the same destination along the same path and treating all packets in the same way. In the company, Switch Smart (manageable) designed with capplication specific integrated circuits (SO C) which are sophisticated enough to recognize different types of packages and treat them differently, but these Switch they can be very expensive.
In a SDN, SysAdmin (Network Administrator) can shape traffic from a centralized control console without having to touch Switch single. The administrator can change any rule of the Switch network when needed, giving or removing priority, or even blocking specific types of packets with a very detailed level of control.
This is especially useful in a multi-tenant architecture (multi-tenant architecture) de Cloud computing because it allows the administrator handle traffic loads flexibly and more efficiently. Essentially, this allows the Network Administrator use fewer small and expensive switches and have more control than ever before over the flow of network traffic.
A las SDN they are sometimes referred to as the "Cisco Killer" because it allows Network Engineers Support fabric switching through multi-vendor hardware and application-specific ICs. Currently the most popular specification for creating a SDN is the open standard OpenFlow, which as we read before allows Sysadmin control routing tables remote form.
