Project Proposal for DMM
|
Hello FD.io TSCs
Please accept this project proposal for DMM for consideration. https://wiki.fd.io/view/Project_Proposals/DMM
If possible I would like to present this on 1/25 TSC meeting.
Thanks, George

Two related sets of questions: I am having trouble understanding from the proposal page what this will really do? What problem is it trying to solve? And I am unclear as to the relationship with vpp or fd.io? At a guess from the material it is trying to define a general mechanism for multiple applications to share an interface?
Thank you, Joel

Hi Joel, This is my understanding. /yalei 2018-01-11 23:06 GMT+08:00 Joel Halpern <joel.halpern@...>:
[yalei] Various apps may need match various protocol stack. DMM want to provide a common protocol stack interface/framework between vpp and app, then the unmodified app could use a proper stack based on dynamically or static configuration.

Can that be made to work with existing (e.g. socket) interfaces from the applications? So that an application that is written to use the Linux kernel stack could by configuration, maybe with some small code changes in its startup code, use fd.io TLDK?
Yours, Joel

Hi Joel, The idea is to provide a abstract network stack framework in fd.io such that the framework takes care of choosing the network stack(vpp, lwip, tldk, kernal stack...) based on the Application(QOS), network state etc.. Here Applications still use posix API syntax but which to use kernel stack or VPP stack or vpp's TLDK or lwIP(lightweight IP) etc.... decided by the table entry mention above diagram. This table will be populated by Controller or Orchestrator based on QOS of application or network state or other reasons.... Note: Will have No impact to existing applications. Thanks & Regards, Satish.

Hi Joel,
The short answer is Yes.
DMM can and is actually planning to integrated with existing stacks, such as host stack and TLDK. It can also integrated with other third party stacks, such as Tencent’s F-stack and LWIP. It is a framework supports both user and kernel space, with multiple protocols and multiple instances.
Thanks, George
