Why an sFlow blog?

sFlow has been quietly emerging as the leading multi-vendor standard for monitoring traffic in switched networks. The first sFlow capable switches were shipped in 2001. Since then vendor support has been increasing each year and now switches from Brocade, Hewlett-Packard, Juniper Networks, Extreme Networks, 3Com, D-Link, Alcatel-Lucent, H3C, Hitachi, NEC, AlaxalA, Allied Telesis and Comtec have embedded sFlow. Chances are you already have switches in your network that support sFlow (for a complete list of switches that support sFlow, see Network Equipment).

sFlow monitoring solutions provide traffic visibility for the full range of switched networks, from an organization running a large, busy 10G network (see Amsterdam Internet Exchange) to a small office trying to see who is hogging bandwidth on their T1 link (see sFlowTrend).

Through the postings in this blog, we hope to increase awareness of sFlow and the way it can be used to solve problems that challenge network administrators every day.
