sFlow

(SampledFLOW) A network packet sampling protocol that exports every nth packet to a traffic analysis application. Supported by many network device manufacturers, sFlow operates at Layer 2 and can be used for all types of network traffic. See IPFIX and network analyzer.

Several protocols, such as sFlow [83],can be utilized to monitor traffic in the SDN environment.
CARACTERISTICAS: Concentracion de enlaces, soporte VLAN, snooping IGMP, soporte para Syslog, copia de puertos, Broadcast Storm Control, soporte IPv6, actualizable por firmware, sFlow, admite Spanning Tree Protocol (STP), soporte de Access Control List (ACL), Protocolo de control de adicion de enlaces (LACP), control de acceso mediante puertos, Dynamic VLAN Support (GVRP), Class of Service (CoS).
Also handy is that SFlow provided some traffic management while we worked out the components of our DDOS mitigation.
Creating standards-based solutions with sFlow and OpenFlow to deliver scalable SDN solutions
A10's support for the sFlow standard allows us to integrate detailed threat metrics from Thunder TPS with data from a wide range of physical and virtual switches, routers, hosts and applications to provide comprehensive visibility to operations teams.
This was followed by the eventual definition of sFlow as RFC-3176 in 2001.
These include port security, DHCP Snooping, Dynamic ARP Inspection, IP Source Guard, ingress/egress ACL, sFlow, Storm Control, automatic Denial-of-Service prevention and port access control via 802.
The 6610s support full Layer 3 capabilities — IPv4,IPv6and multicast — sFlow for network traffic accounting, 12,000 ACLs, 16,000 routes, 32,000 MAC table entries and 8,000 multicast groups.
The enhanced switch includes the sFlow specification mechanism that enables traffic monitoring on all ports and reports this to an external sFlow collector application.
There is also sflow, which provides measurements based on samples of incoming traffic.
First, these systems analyze network traffic data--such as NetFlow, cFlow, sFlow and IPFix-from routers, switches or specialized appliances throughout the network These APM systems build a baseline of the systems, users and traffic inside the network and continuously monitor their activity, alerting operations teams of disruptions.
The solution is built upon three key elements -- sFlow, an industry standard for real-time traffic monitoring supported on Foundry's switch and router product lines, Foundry's IronView Network Manager (INM) and Snort, an open source industry standard for intrusion detection and prevention.
