I2RS WG: Two replacements for Ephemeral-REQ-05:
Option 1: I2RS pub-sub, logging, RPC or other mechanisms may lead to undesirable or unsustainable resource consumption on a system implementing an I2RS Agent. It is RECOMMENDED that mechanisms be made available to permit prioritization of I2RS operations, when appropriate, to permit implementations to shed work load when operating under constrained resources. An example of such a work shedding mechanism is rate-limiting. Option 2: Ephemeral state handling, notifications, and OAM could increase the data flow rates across transport, or the rate of publication of data in a subscription, or logging needed for traceability. It is RECOMMENDED that the I2RS Agent should have the ability to limit, prioritize or split data flows in the I2RS protocol. Any feedback?

The I2RS Agent SHOULD have the ability to constraints for OAM functions operating to limit CPU processing, data rate across a transport, the rate of publication of data in a subscription, and logging rates; and the I2RS Agent SHOULD have the ability to prioritize some of the management data flows between the I2RS Agent and I2RS Client. In order to constrain resources needed, the I2RS Agent MAY also schedule data flows or split data flows unto multiple data flow streams. Suggested new text: I2RS pub-sub, logging, RPC or other mechanisms may lead to undesirable or unsustainable resource consumption on a system implementing an I2RS Agent. It is RECOMMENDED that mechanisms be made available to permit prioritization of I2RS operations, when appropriate, to permit implementations to shed work load when operating under constrained resources. An example of such a work shedding mechanism is rate-limiting. ----- Note that Subscription QoS in the pub-sub requirements provides for this type of behavior in that context. -- Jeff _______________________________________________ i2rs mailing list [email protected] https://www.ietf.org/mailman/listinfo/i2rs _______________________________________________ i2rs mailing list [email protected] https://www.ietf.org/mailman/listinfo/i2rs
