RoutingStacks

RoutingStacks is a conceptual framework used in computer networking to describe the organization and layering of routing protocols and functionalities. It posits that routing can be viewed as a stack of different levels, where each level is responsible for a specific aspect of path determination and packet forwarding. At the foundational level are the link-state or distance-vector protocols, which are concerned with discovering network topology and calculating shortest paths. Moving up the stack, higher levels might handle inter-domain routing, such as Border Gateway Protocol (BGP), which manages routing between different autonomous systems. Further levels could incorporate policy-based routing, traffic engineering, or quality of service (QoS) considerations, where routing decisions are influenced by factors beyond simple hop count or link cost. The RoutingStacks model helps in understanding the modularity and interdependencies within complex routing architectures, allowing for the development and integration of new routing features without disrupting existing functionalities. It provides a structured approach to analyzing how different routing algorithms and protocols interact to ensure efficient and reliable data delivery across diverse network environments. This layered perspective is valuable for network engineers and researchers when designing, troubleshooting, and optimizing network routing.
