Fast ReRoute: The Rise of Optimization and Constraint-Aware FRR
Introduction Fast Reroute (FRR) is one of the defining capabilities of RSVP-TE, enabling networks to recover from failures in tens of milliseconds rather than waiting for full control-plane convergence. By precomputing backup paths and shifting protection into the data plane, FRR allows traffic to be redirected almost instantaneously at the point of failure (Point of…
A Systems Approach to Understanding the Bandwidth Management Control Loop
Bandwidth management(BW) in traffic-engineered (TE) networks is often discussed in terms of specific protocols or architectural models. Yet before debating different architectural models or protocol specific details, it is useful to step back and understand the functional problem being solved. At its core, bandwidth management is a control loop. It observes network conditions, interprets those…
Does Segment Routing Simplify Traffic Engineering?
Segment Routing is frequently positioned as a simpler approach to Traffic Engineering(TE) because it can reduce protocol surface area and eliminate per-LSP signaling in the core. That description is broadly accurate at the signaling layer, but it does not remove the underlying TE requirements. TE still requires intent to be expressed, constraints to be applied,…
