ITD won the Best of Interop 2015 in Data Center Category.


ITD provides :

  1. Hardware based multi-terabit/s L3/L4 load-balancing at wire-speed.
  2. Zero latency load-balancing.
  3. CAPEX savings : No service module or external L3/L4 load-balancer needed. Every Nexus port can be used as load-balancer.
  4. Redirect line-rate traffic to any devices, for example web cache engines, Web Accelerator Engines (WAE), video-caches, etc.
  5. Capability to create clusters of devices, for example, Firewalls, Intrusion Prevention System (IPS), or Web Application Firewall (WAF), Hadoop cluster
  6. IP-stickiness
  7. Resilient (like resilient ECMP), Consistent hash
  8. VIP based L4 load-balancing
  9. NAT (available for EFT/PoC). Allows non-DSR deployments.
  10. Weighted load-balancing
  11. Load-balances to large number of devices/servers
  12. ACL along with redirection and load balancing simultaneously.
  13. Bi-directional flow-coherency. Traffic from A–>B and B–>A goes to same node.
  14. Order of magnitude OPEX savings : reduction in configuration, and ease of deployment
  15. Order of magnitude CAPEX savings : Wiring
