The Agile Network is Here and Happening
SDN and NFV are no longer buzzwords; they have rapidly covered much ground and are ready for some serious action
The last one-year has been transformative for the enterprise networking landscape, to say the least. Developments in areas of software defined networking (SDN) and network function virtualization (NFV) have led to redefining the manner in which networks are being deployed and consumed.
Major players in India
While Cisco continues to be the leader in the Layer 4-7 switch category, which is also referred to as the data center switches, it is facing increased competition from a host of players such Alcatel-Lucent, Huawei and HP. Other key players in the segment included Avaya, Brocade, Citrix, Radware and Riverbed. The Layer 2 and 3 segments are relatively more crowded, especially in the lower price sub-segments. Some of the other players in the India market include ZTE, Dell, Extreme, D-Link and Dax.
In the routers category too, Cisco continues to be the market leader, while Juniper, Huawei and Alcatel-Lucent are some of the other notable players.
The WLAN segment is a somewhat fragmented market, even though the top five players put together command close to 75 percent of the market. These are Cisco, D-Link, TP-Link, Smartlink and Netgear.
In terms of speed, the market has started moving in favor of 10 G, especially for greenfield backbone deployments, even though the deployed base of 1G continues to be widespread.
SDN and NFV have come to the forefront of networking technologies and the trend is only expected to strengthen further as enterprises realized the benefits of these technologies, which enable them to be not only more agile but also cost-efficient. Players like VMware, which come from the software side, are also challenging the traditional networking models with their software defined data center (SDDC) kind of models.
Among the various industry groups and forums that are globally working to develop next generations and iterations SDN and NFV technologies the prominent ones are Open Networking Foundation (ONF) that promotes the SDN protocol OpenFlow, and OpenDayLight project that recently released the Beryllium version of its SDN platform. With the Beryllium release, OpenDayLight’s (ODL) support
