Cisco Intelligent Traffic Director (ITD) is an innovative solution to bridge the performance gap between a multi-terabit switch and gigabit servers and appliances. It is a hardware based multi-terabit layer 4 load-balancing, traffic steering and clustering solution on the Nexus 5k/6k/7k/9k series of switches.
It allows customers to deploy servers and appliances from any vendor with no network or topology changes. With a few simple configuration steps on a Cisco Nexus switch, customers can create an appliance or server cluster and deploy multiple devices to scale service capacity with ease. The servers or appliances do not have to be directly connected to the Cisco Nexus switch.
ITD won the Best of Interop 2015 in Data Center Category.
With our patent pending innovative algorithms, ITD (Intelligent Traffic Director) supports IP-stickiness, resiliency, consistent hash, exclude access-list, NAT (EFT), VIP, health monitoring, sophisticated failure handling policies, N+M redundancy, IPv4, IPv6, VRF, weighted load-balancing, bi-directional flow-coherency, and IPSLA probes including DNS. There is no service module or external appliance needed. ITD provides order of magnitude CAPEX and OPEX savings for the customers. ITD is much superior than legacy solutions like PBR, WCCP, ECMP, port-channel, layer-4 load-balancer appliances.
ITD provides :
- Hardware based multi-terabit/s L3/L4 load-balancing at wire-speed.
- Zero latency load-balancing.
- CAPEX savings : No service module or external L3/L4 load-balancer needed. Every Nexus port can be used as load-balancer.
- Redirect line-rate traffic to any devices, for example web cache engines, Web Accelerator Engines (WAE), video-caches, etc.
- Capability to create clusters of devices, for example, Firewalls, Intrusion Prevention System (IPS), or Web Application Firewall (WAF), Hadoop cluster
- Resilient (like resilient ECMP), Consistent hash
- VIP based L4 load-balancing
- NAT (available for EFT/PoC). Allows non-DSR deployments.
- Weighted load-balancing
- Load-balances to large number of devices/servers
- ACL along with redirection and load balancing simultaneously.
- Bi-directional flow-coherency. Traffic from A–>B and B–>A goes to same node.
- Order of magnitude OPEX savings : reduction in configuration, and ease of deployment
- Order of magnitude CAPEX savings : Wiring, Power, Rackspace and Cost savings
- The servers/appliances don’t have to be directly connected to Nexus switch
- Monitoring the health of servers/appliances.
- N + M redundancy.
- Automatic failure handling of servers/appliances.
- VRF support, vPC support, VDC support
- Supported on all linecards of Nexus 9k/7k/6k/5k series.
- Supports both IPv4 and IPv6
- Cisco Prime DCNM Support
- exclude access-list
- No certification, integration, or qualification needed between the devices and the Cisco NX-OS switch.
- The feature does not add any load to the supervisor CPU.
- ITD uses orders of magnitude less hardware TCAM resources than WCCP.
- Handles unlimited number of flows.
- Load-balance traffic to 256 servers of 10Gbps each.
- Load-balance to cluster of Firewalls. ITD is much superior than PBR.
- Scale IPS, IDS and WAF by load-balancing to standalone devices.
- Scale the NFV solution by load-balancing to low cost VM/container based NFV.
- Scale the WAAS / WAE solution.
- Scale the VDS-TC (video-caching) solution.
- Scale the Layer-7 load-balancer, by distributing traffic to L7 LBs.
- ECMP/Port-channel cause re-hashing of flows. ITD is resilient, and doesn’t cause re-hashing on node add/delete/failure.

Data traffic has grown dramatically in the recent years, leading to increased deployment of network service appliances and servers in enterprise, data center, and cloud environments. To address the corresponding business needs, network switch and router architecture has evolved to support multi-terabit capacity. However, service appliance and server capacity remained limited to a few gigabits, far below switch capacity.

It may sound strange to hear me say it, but when I wrote the previous blog post about Dynamic FCoE I thought that it may get a little blip of attention and then filed away as a “oh, that is cool” little factoid about Cisco’s storage portfolio. Perhaps I shouldn’t have been so nonchalant, but I confess I was not expecting the number of questions that I (and other speakers at CiscoLive back in May) have been getting about the technology.
Many questions – including some in the comments of the previous blog – have indicated a strong desire to know more, and they have been excellent and well-thought out. I’m going to try to address some of them in a deeper dive blog whenever I can, in the hopes of being able to address some of the concerns and clarify some points.
We’ll start with one of the biggest concerns – sharing the spine layer for logical separation of SAN A/B, and what happens if one of the spine switches (nodes) go offline. Read More »

As we start off this New Year, how about including a resolution to improve application delivery? In Best Practices for Application Delivery in Virtualized Networks – Part I , we covered key application delivery challenges that have come up due to the complexities of managing the many types of applications that enterprises use today, and further complicated by data center consolidation and virtualization. We then covered some best practices, courtesy of Dr. Jim Metzler’s 2011 Application Service Delivery Handbook, which recommended taking a lifecycle approach to planning and managing application performance.
A key step to the lifecycle approach is to implement network and application optimization tools, such as WAN Optimization solutions and Application Delivery Controllers, including server load balancers. Of course, these solutions are not new to the market and already address many of the needs that exist with delivering enterprise applications in virtualized data centers – namely, the need to ensure network reliability, availability and security for users accessing these applications. In this post, we will discuss a recent study by IDC, where IT decision makers across Europe and the US spoke out about their strategies for using server load balancers to deal with emerging challenges.
. What important attributes do you look for in your server load balancers?
