  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.
