Introduces the VOQ queuing architecture and its role in preventing head-of-line blocking. It covers key features, operational benefits, hardware limitations, and the end-to-end workflow for managing traffic congestion and bandwidth allocation.
Traffic management with VOQs
Explains the Virtual Output Queue (VOQ) queuing architecture designed to enable per-egress interface queuing and prevent head-of-line blocking. It outlines key features such as credit-based scheduling and dynamic instantiation to optimize throughput and minimize packet loss.
Usage guidelines for traffic management with VOQs
Outlines usage guidelines for managing traffic with VOQs, including verifying CGM profile and VOQ resource usage, and provides instructions for safely modifying QoS and queuing policies to prevent congestion-management resource exhaustion.
Limitations of VOQ model
Lists the key hardware and scalability limitations of the VOQ model.
How traffic management with VOQs work
Outlines the internal system behavior and workflow of VOQ-based packet forwarding. It describes how components like ingress interfaces, virtual output queues, and egress schedulers coordinate to ensure efficient, lossless traffic transmission across the switch fabric.
VOQ CGM profile prefitting
Explains how VOQ congestion-management profile prefitting optimizes queue-limit scalability and enables interoperability across supported Cisco 8000 platforms.
