Abstract: Aspects of the disclosed technology address the problems of manually identifying and optimizing service function chaining (SFC) performance in response to changes in traffic profiles. In one aspect of the present disclosure, a method includes monitoring, by a first network component, incoming data packets; detecting, by the first network component, a change in a traffic profile of the incoming data packets; generating, by the first network component, in-band information on changes in the traffic profile; and transmitting, by the first network component, the in-band information with one or more data packets of the incoming data packets, the in-band information being used by a second network component to adjust one or more corresponding settings for servicing the incoming data packets.

Abstract: Aspects of the disclosed technology address the problems of manually identifying and optimizing service chain (SC) performance bottlenecks by providing solutions for automatically identifying and tuning various SC parameters. In some aspects, a SC optimization process of the disclosed technology includes the replication or cloning of a SC for which traffic flow is to be optimized. Traffic flows for the production chain can then be simulated over one or more SC clones to identify and tune individual system parameters, for example, to determine if the simulated changes produce a positive, negative, or neutral change in flow performance. Systems and machine-readable media are also provided.
