IEEE1588 PTPv2 support for CRS317

Thu Nov 21, 2019 11:31 am

We plan to introduce IEEE1588 PTPv2 feature for some of the CRS317 series switches.
At the moment we plan to add support for the IEEE1588 PTPv2 Boundary clock which can be operated by transport layer2/udp4 and possibility to choose the delay-mode end-to-end/peer-to-peer.
Support for the 802.1AS (gPTP) will be also added.
Note that the clock is not synchronised to the system clock.

Maybe you could give us some feedback if you would like to use that feature in our CRS switches?
What additional options you would like us to add for this feature?

Nice feature for W60g,
always needed for Multi-Cell DECT and Video HD-SDI

That is great news.
Just thinking further - together with GPS it could become a really nice Master clock or even grand master...
And it could open the CRS range for use with AVB.

from a provider point-of-view - this is nice to have, but honestly I'd prefer other chip-features implemented available on crs317 hardware.

First make this a reliable switch. Connecting 10G and 1G is still a mess. We get packet loss and vpls tunnels with sporadic outages. I cant even see if flow control is negotiated? How do you test this switch without this information? We consider to remove all our CRS317 at the moment.

Most likely it is impossible to do this in software. It needs a dedicated ASIC and a crystal oscillator
