ITD: Load Balancing, Traffic Steering & Clustering using Nexus 5k/6k/7k

best

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.

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 an hardware based multi-terabit layer 4 load-balancing, traffic steering and clustering solution on the Nexus 7000 and 7700 series of switches.

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.

Making Video Calls Easy for Users

For Gen Y employees in particular, video calls are a normal and expected way to communicate. But now, employees of all ages are asking why their workplace doesn’t offer the tools and support for video calling. Read More »
