就在本月7日,美国运营商AT&T面向该国家100所城市推出了“随选网络”(Network on Demand)。据媒体报道,AT&T推出的这一服务基于SDN技术,商业客户可根据需求自行管理和调整网络,比如订购更多的端口、添加和更改网络服务、扩展带宽等,更重要的是,这种网络管理能力并不需要很长时间的业务流程和调试时间,用户只需要花几分钟的时间在管理界面上做下修改即可。能够基于SDN技术实现如此大规模网络环境下的商业服务,在全球范围内也属少数,而对比国内,中国的SDN发展还处于早期“百花齐放、百家争鸣”的探索阶段。
Just this month, U.S. operator AT & T launched Network on Demand for 100 cities in the country. According to media reports, AT & T’s service is based on SDN technology. Commercial customers can manage and adjust their networks according to their needs, such as ordering more ports, adding and changing network services, expanding bandwidth, and more importantly, Management does not require a long time business processes and debugging time, users only need a few minutes to make changes in the management interface can be. Being able to realize commercial services under such large-scale network environment based on SDN technology is also a minority in the world. Compared with the development of SDN in China and at home, SDN is still in its early stage of exploration, such as “letting a hundred flowers blossom and a hundred schools of thought contend.”
