ITDITD
Cisco Intelligent Traffic Director (ITD)
Benefits:
• Reduced Cost of Ownership: Line-rate scaling of traffic distribution across services without the need of external devices.
• Lower cost of operation: via simplified provisioning, ease of deployment, and reduced complexity
• Investment protection: IPv4 & IPv6 support today and runs on all Nexus 7000/7700 systems
ITD Overview:
• Utilizes HW hashing to provide scalable layer 3/4 line-rate traffic distribution for services
• Optimizes TCAM utilization to provide a highly scalable solution for distributing traffic across services and servers
• Order of magnitude reduction in configuration
• Integrated health monitoring of services to help ensure the highest level of service availability
Challenge: Effectively distribute traffic high bandwidth traffic across services as a cost effective solution
