 DMM (Dual Mode, Multi-protocol, Multi-instance) is a framework between applications

-networking stack instances operating on different domains (kernel/user-space) or even with
+and transport layer of networking stack. This framework can host different types of
+networking stack instances operating on different domains (kernel/user-space)  with
 different protocol suites (TCP/IP, RDMA, or others). Application can use different type of
 protocol stack implementations based on functional/performance requirements.

 # 2.  History:
 Emerging applications are bringing extremely high-performance requirements to the
-network system. Eg. AR/VR, IOT etc. And Many of them coming with their unique demand
-of QOS/SLA. Some application need low latency network, some need high reliability etc.

 Though such performance targets should be required for the complete communication system,

 Thus, the traditional single-instance TCP-based network stack bears great challenges when
