ITD: Intelligent Traffic Director

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.

ITD (Intelligent Traffic Director) is a hardware based multi-Tbps Layer 4 load-balancing, traffic steering and clustering solution on Nexus 7xxx series of switches. It supports IP-stickiness, resiliency, 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 available on Nexus 7000/7700 series in NX-OS 6.2(8) or later. It is available for demo on Nexus 5k/6k. ITD is much superior than legacy solutions like PBR, WCCP, ECMP, port-channel, layer-4 load-balancer appliances.

Get Inspired by Cisco Live Europe 2014

Cisco Live Europe 2014 (Milan) just ended and I think I will need a few days to reorganize my ideas. It was my first opportunity to attend #CLEUR, and moreover I did it as a CCIE.

CLEUR is not just a Cisco event (or should I say THE Cisco event) but also a unique opportunity to experience technology, expertise, vision, and inspiration.  And of course meet friends. Read More »

Enabling a Scalable Cloud-Based Model with Cisco WAAS

On my recent road trip from Vancouver to Whistler Village, I was stunned by the breathtaking beauty of British Columbia. Its lush green trees, majestic waterfront fjord, and picturesque hill tops could easily be mistaken as oil paintings by Claude Monet. Along the drive up the Sea-to-Sky Highway, I stopped at a fast food vendor for a quick budget meal only to be captivated by a million dollar view -- see my photo on the right.

As I gazed from the rigid mountain top and snowy peaks to the clusters of cumulus clouds floating serenely above, it reminded me of our upcoming launch in San Diego and solutions that Cisco will introduce to enable the world of many clouds.

Last November, Cisco Global Cloud Index forecasted “greater than 50% of all workloads will be processed in the cloud by 2014.” Over one-third of data center traffic, as highlighted in the report, will be cloud based. As a result, download and upload speeds as well as latencies are vital measures to assess network capabilities for cloud readiness.

In a recent Global Cloud Networking Survey conducted by Cisco with more than 1,300 IT professionals, 37% of the respondents cited “a cloud-ready network” as the biggest element in designing an infrastructure for cloud deployments. And from my previous post Journey to Cisco Live San Diego, we identified the key requirements a cloud delivery solution must address. Today, we’ll explore how the Cisco Wide Area Application Services (WAAS) portfolio can help achieve a scalable cloud-based model.
