The DC solution supports key features such as L3 fabric, controllerless management using EVPN, network segmentation and virtualization using VXLAN, multihoming for redundancy, BFD for faster convergence, ACL/QoS policies for fine grained control, support for
sFlow and management automation.
The effectivity of our placement mechanism is validated on an SDN framework with OpenDaylight [15], NetFPGA-10G [16] and
sFlow [17].
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
sFlow, a technology designed for network monitoring based on packet sampling, derives from early work performed by HP at the University of Geneva and CERN in 1991.
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 802.1x including multi-client authentication, Radius VLAN/policy assignment and guest/unauthenticated VLAN.
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.
