Traffic Engineering
Traffic engineering optimizes data flows across the network to deliver high performance, reliability, and efficiency. Using control-plane path selection, it keeps traffic on predefined, consistent paths for maximum performance.
Cisco Silicon One supports various methods such as - Segment Routing, Policy-Based Routing, and Static Pinning - giving operators precise control to meet the demanding requirements of modern AI networking.
Segment Routing
Segment routing encodes the precise network path directly into each packet, allowing explicit, deterministic routing without relying on hop-by-hop tables.
This method delivers predictable performance and efficient network utilization, with minimal control-plane overhead.
Policy Based Routing
Policy-based routing empowers operators to define flexible, granular forwarding decisions based on packet attributes such as source, destination, application, or protocol.
With centralized intent and distributed execution, policies can dynamically adjust to network conditions, enabling advanced traffic steering and service differentiation across the network.
This approach is ideal for environments requiring adaptive, application-aware control.
Static Pinning
Static pinning assigns specific flows to dedicated network paths or resources using local pin-tables that are set for example per source and destination. If a path becomes unavailable, flows are distributed using static or dynamic ECMP, ensuring quick adaptation without needing centralized control-plane updates.
This approach offers efficient, low-overhead traffic steering for predictable, stable network environments.
