Hi Yujing, I roughly read your draft. It's good idea to use NSH as transport for INC applications.
I wish the following comments could help you promote it and welcome discussion. 1. First of all, I want to make sure that you just use NSH to signal INC functions OR you use it to transmit data flows of applications as well. If the later is true, can five-tuple be enough to distinguish task-level or sub-task-level data flows within one INC application? Shouldn't additional information (e.g. app id) be used for decision-making? 2. As RFC7665 defines, the entry to SFC domain is SC(Classification) but you use "SFC proxy" in the draft. SFC proxy is defined to deal with NSH-unaware SFs. 3. I am confused by '"heterogeneity of scenarios" in the introduction. Did you mean the co-existing of multiple applications in programmable switches. Besides, NSH uses SPI and SI to indicate consecutive processing of service functions. In terms of use case, does SINC require chaining of INC to process single data flow?

In this draft, we want to discuss a mechanism "Signaling In-Network Computing operations" (SINC) to enable in-packet operation signaling for in-network computing for specific scenarios. Hope to get your review and comments. Many thanks!
