Bandwidth-Aware Traffic Engineering: First Principles for Real Networks
Traffic engineering exists because networks are finite. Links have limits, traffic competes, and assumptions eventually collide with physics. Over decades of network evolution, architectures and control systems have come and gone, but the fundamental challenge has not changed: How to move traffic through a shared infrastructure without exceeding what the network can safely deliver? In…
A Traffic Engineering Process Perspective
RFC 9522 provides a useful framing for the realization of traffic engineered networks by introducing the principles of TE. This post focuses on describing the problem space of TE, the requirements that fall out of it, and a balanced architectural approach. RFC 9522 Matters Traffic engineering discussions often drift toward technical protocol advocacy and arguments…
