DMM

DMM (Dual Mode, Multi-protocol, Multi-instance) is a concept to provide a transport agnostic framework for the applications where applications can

Work with both user and kernel mode network stack.
Use different network protocol stack based on their functional and performance requirement (QOS).
Work with multiple instance of transport protocol stack.
Engage or adopt new protocol stack dynamically.

Existing applications or new applications use Posix compatible and uniform socket API library (via system hijacking or LD_PRELOAD).
Neuro Resource Discovery learn the set of protocol policies to route the packet. It can be like controller continuously monitor the network state and can update the policy rules dynamically on need basis.
Local protocol policy orchestrator regularly sync with nRD.
Session layer of DMM (nSocket) lookup this protocol orchestrator for any new session request and manages the session mapping and other info’s.
Based on protocol lookup the corresponding protocol stack is chosen.

DMM supports different protocols on both kernel and user space
With the DMM framework, system operators can plug-in dedicated types of networking stack instances according to performance and/or functional requirements from user applications

No current or expected issues with vendor neutrality

Meets board policy as expressed in Technical Community Charter and IP Policy
