OpenDaylight 另一個Open Source SDN /NFV 整合計畫

在了解什麼是Opendaylight 計畫之前，要先了解幾個專有名詞 Software-Defined Networking (SDN)、Network functions Virtualization (NFV) 和 Network Virtualization (NV)，參考Which is Better – SDN or NFV 這篇文章：

SDN – separates the network’s control (brains) and forwarding (muscle) planes and provides a centralized view of the distributed network for more efficient orchestration and automation of network services.

NFV – focuses on optimizing the network services themselves. NFV decouples the network functions, such as DNS, Caching, etc., from proprietary hardware appliances, so they can run in software to accelerate service innovation and provisioning, particularly within service provider environments.

NV – ensures the network can integrate with and support the demands of virtualized architectures, particularly those with multi-tenancy requirements.

OpenDaylight Project

OpenDaylight Project 的目的在解決IT領域最嚴峻的挑戰，那就是簡化網路管理 

                                         ~OpenDaylight 技術指導委員會主席David Meyer


OpenDaylight 是一個由Linux Foundation 所發起的大型協同Open Source 專案，目標是開發出一個可支援各種協定，並快速朝向SDN/NFV 方向發展的架構，同時不會獨厚任何單一廠商。

前一陣子OpenDaylight Release 了第一版代號 - Hydrogen







原本我以為 OpenDaylight 之於 SDN / NFV 就像 OpenStack 之於Xen, KVM , Vmware....，不過比較深入了解後，應該跟各家廠商平行且競爭的地位，目的是取代和統整各家SDN Vendor 的 Controller 角色，根據Top 10 Carrier SDN Vendors 這篇文章，目前市場上的Key Player - SDN Vendor 整理如下：

• OpenDaylight 
• VMware/Nicira
• Juniper/Contrail
• ConteXtream
• Big Switch Networks
• Cyan
• Alcatel-Lucent/Nuage
• Cisco/Insieme
• Plexxi
• Ciena
• Brocade/Vyatta

更多SDN Controller Vendor 清參考Controller Wars 2.0

嗯....不知道有沒有模擬器可以玩？且讓我研究研究....
