Transport Layer Networking (2204.02861v1)

Abstract: In this paper we focus on the invention of new network forwarding behaviors between network Layers 4 and Layer 7 in the OSI network model. Our design goal is to propose no changes to L3 - The IP network layer, thus maintaining 100% compatibility with the existing internet. Small changes are made to L4 the transport layer, and a new design for a session ( L5 ) is proposed. This new capability is intended to have minimal or no impact on the application layer, except for exposing the ability for L7 to select this new mode of data transfer or not. The invention of new networking technologies is frequently done in an academic setting, however the design needs to be constrained by practical considerations for cost, operational feasibility, robustness and scale. Our goal is to improve the production data infrastructure for HEP 24/7 on a global scale.
