1. A method comprising:
obtaining, from a first sub-domain included in an end to end service chain of a network system, a first measurement of performance of the first sub-domain;
obtaining, from a second sub-domain included in the end to end service chain, a second measurement of performance of the second sub-domain;
aggregating the first measurement and the second measurement;
determining an estimated performance of the end to end service chain based on the aggregating;
receiving a request from the first sub-domain to alter a configuration of the first sub-domain; and
conditionally modifying the network system based on the estimated performance, including responding to the first sub-domain with a denial of the request,
wherein the denial of the request includes an indication of a time interval during which no changes to the configuration of the first sub-domain are permitted,
wherein the aggregating of the first measurement and the second measurement comprises adjusting the first measurement by a first weight assigned to the first sub-domain and adjusting the second measurement by a second weight assigned to the second sub-domain.
