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.

Tech­nol­ogy Trends

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
