Model Routing in Microsoft Foundry: Choosing the Right Model per Task
An enterprise assistant answers routine questions about expense policies, explains complex engineering incidents and occasionally orchestrates tools to resolve a service request. Running every request […]
Read articleBGP Route Selection Explained
BGP is a policy protocol. When a router learns multiple valid routes to the same prefix, it does not simply choose the path with the […]
Read articleBGP Communities for Traffic Engineering
BGP communities are labels attached to routes so routing policy can act on meaning rather than repeating long prefix lists everywhere. A community does not […]
Read articleUnderstanding Policy-Based Routing (PBR): Configuration and Benefits
Modern computer networks are no longer simple paths where data just flows from one point to another in a predictable straight line. Instead, they are […]
Read articleHow Fibre Channel Switching Powers High-Speed Storage Networks
Fiber channel switching is the process of using intelligent switching devices to create a high-performance, structured network—often called a fabric—that connects servers and storage systems […]
Read articleUnderstanding ToR (Top-of-Rack) Switching in Network Architecture
Top-of-Rack switching refers to a data center network design approach where network switches are installed directly at the top section of each server rack. In […]
