does mrpd and gptp daemon support CLASS CDT? #805

Open Tejas210 opened 6 years ago

Hi,

I am working on TSN test application. CLASS CDT (Control Data Traffic ) is newly added in TSN. Does mrpd and gptp daemon support CLASS CDT? Also, Does mrpd and gptp daemon support AVB to TSN related changes?

Regards, Tejas Patel

I don't think a new traffic class has any impact on gPTP operation. In any case, I'm not aware of much work towards implementing 802.1AS-rev changes in our gPTP daemon here.

Our mrpd doesn't explicitly support a CDT class, but it also doesn't really care which class ID values you use. More importantly, we don't have any means of supporting the new methods of centrally-managed configuration of SRP that would typically be used with CDT class traffic.

TSN encompasses the AVB standards, for the most part, rather than replacing them entirely. The code here remains focused on the older AVB portions of the TSN standards for now, but I believe some groundwork is being laid for more support of newer TSN standards.
