The people that I work with find sFlow limiting and most of the time are quite disappointed in the results. Reply. Delete. Jake Wilson September 17, 2012 at 6:12 AM. sFlow does not cache data, instead sFlow datagrams are sent in real-time to a collector where they are analyzed. SNMP and NetFlow Support by Vendors. Comparing sFlow to NetFlow Two key tools that network administrators often turn to for network monitoring are NetFlow from Cisco and sFlow from InMon. A fiery debate arises when discussing flow technologies i.e. NetFlow vs. sFlow. Network monitoring has … As we all know, existing flow technologies act as a vital and viable solution to troubleshoot network and bandwidth issues. SFlow was developed by InMon Corporation. sFlow stands for sampled Flow and is used for exporting packets at the data link layer. SFlow vs NetFlow vs SNMP, the differences are hence clear: SNMP for standard network monitoring whereas SFlow/NetFlow for high traffic network traffic collection, monitoring and analysis. sFlow can provide statistics on different protocols from Layer 2 to Layer 7 of the OSI model. This issue may be solved by using sFlow instead of NetFlow. SFlow vs NetFlow, the debate between these two flow protocols has been around for many years. With sFlow, the device that receives the sampling packet must generate all the metadata. SNMP is defined in RFC 1157 (August 1990) but the design of SNMPv1 was done already in the 1980s. Here is the correct URL when testing NetFlow Vs. sFlow: We get this question all the time, so we figured we give a quick analysis and rundown of the two flow export protocols to show you some of the main differences between them. Collecting traffic data, correlating it into a usable format, and presenting it to the user through a web-based interface for monitoring network traffic. Somehow the URL got cut off in my last post. On the surface, these tools seem to provide similar capabilities, so many network admin teams feel as … While NetFlow processes all of the packets flowing through the interface on a router or firewall and the metadata is created on the device itself, switches supporting sFlow send a sampling packet of the traffic it’s receiving through its interfaces. Netflow vs sFlow, whats the difference between these to flow protocols and which one should you be using?. Finally, IPFIX/NetFlow and sFlow are largely complementary and most enterprises will likely use both, see LAN and WAN. Netflow vs sFlow. It is designed to be compatible on many different platforms of switches and network routers, which allows SFlow to grow in popularity. Monitoring IPFIX, Cisco NetFlow, Juniper J-Flow, sFlow, and Huawei NetStream flow data allowing it to identify which devices, applications, and protocols are the highest bandwidth consumers. It is a stateless packet sampling protocol designed for fast monitoring samplings. 14 comments on “ NetFlow vs. sFlow for Network Monitoring and Security: The Final Say ” Jimmy D says: August 28, 2012 at 8:21 am . SFlow SFlow developed by InMon is a packet sampling technology where the switch captures every 100th packet (configurable) per interface and sends it off to the collector. Great post Adam. Replies.
