sflow vs netflow

As we all know, existing flow technologies act as a vital and viable solution to troubleshoot network and bandwidth issues. 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. 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. NetFlow vs. sFlow. Delete. Here is the correct URL when testing NetFlow Vs. sFlow: sFlow stands for sampled Flow and is used for exporting packets at the data link layer. Great post Adam. sFlow does not cache data, instead sFlow datagrams are sent in real-time to a collector where they are analyzed. Network monitoring has … A fiery debate arises when discussing flow technologies i.e. Netflow vs sFlow, whats the difference between these to flow protocols and which one should you be using?. 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. Comparing sFlow to NetFlow Two key tools that network administrators often turn to for network monitoring are NetFlow from Cisco and sFlow from InMon. On the surface, these tools seem to provide similar capabilities, so many network admin teams feel as … SNMP is defined in RFC 1157 (August 1990) but the design of SNMPv1 was done already in the 1980s. Collecting traffic data, correlating it into a usable format, and presenting it to the user through a web-based interface for monitoring network traffic. SFlow vs NetFlow, the debate between these two flow protocols has been around for many years. 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. It is designed to be compatible on many different platforms of switches and network routers, which allows SFlow to grow in popularity. Finally, IPFIX/NetFlow and sFlow are largely complementary and most enterprises will likely use both, see LAN and WAN. Reply. Reply. Jake Wilson September 17, 2012 at 6:12 AM. Netflow vs sFlow. It is a stateless packet sampling protocol designed for fast monitoring samplings. With sFlow, the device that receives the sampling packet must generate all the metadata. Somehow the URL got cut off in my last post. SFlow vs NetFlow: SFlow for Multiprotocol, NetFlow for Better Accuracy. SNMP and NetFlow Support by Vendors. 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. The people that I work with find sFlow limiting and most of the time are quite disappointed in the results. sFlow can provide statistics on different protocols from Layer 2 to Layer 7 of the OSI model. SFlow was developed by InMon Corporation. Replies. This issue may be solved by using sFlow instead of NetFlow.
