Subject: Re: [dpdk-dev] [PATCH] [RFC]: adds support PPS(packet per second) on meter
Date: Tue, 23 Feb 2021 02:11:40 +0000 [thread overview]
Message-ID: <DM6PR12MB409082E575443EAB9E24D71ABF809@DM6PR12MB4090.namprd12.prod.outlook.com> (raw)
In-Reply-To: <CACZ4nhsX9LOMrYpr_hUmUE2YseO7Ec7+f1LA0_DSvbnLN8K1Tw@mail.gmail.com>
Yes, RFC2697 is using BPS only.
We change srTCM_PPS mode name to sprTCM.
Single Packet Rate Three Color Marker (sprTCM) - - similar to IETF RFC 2697 but rate is packet per second.
There is no draft or link to this new mode (sprTCM)
Regards,
Li Zhang
