Episode notes
Traditional routing protocols like OSPF simply choose the “shortest” path. If the shortest path is full of traffic and there are alternate paths carrying nothing, OSPF can’t help you. Path Computation Element (PCE) along with Path Computation Element Protocol (PCEP) is a way to construct forwarding paths through the network based on factors that distributed ... Read more »

HN817: Is There a Better Way to Do Software Defined Networking?
Software Defined Networking (SDN) is a centralized architecture in which a controller, or a hierarchy of controllers, runs software that computes network-engineered paths and pushes that forwarding scheme into the network. It’s also very complex, which can lead to network failures. What if there was a way to keep the benefits of SDN while also ... Read more »
