Exposed Buffer Architecture addresses network ossification by confronting the virtualization that is inherent to the Internet architecture. In the Internet stack below the Network Layer, the Link layer models services that are local to network nodes, or that connect them in local area networks. Aggregating these low level resources in the implementation of IP to implement wide area services serves two different purposes: 1) It virtualizes local services, enabling interoperability through the adoption of a common model, and 2) It hides the topology of local infrastructure. The premise of Exposed Buffer Architecture is that we can separate these two tasks.
