The IESG has approved the following document: - 'ALTO Incremental Updates Using Server-Sent Events (SSE)' (draft-ietf-alto-incr-update-sse-22.txt) as Proposed Standard
This document is the product of the Application-Layer Traffic Optimization Working Group. The IESG contact persons are Mirja Kühlewind and Magnus Westerlund. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-alto-incr-update-sse/ Technical Summary This document allows the base ALTO protocol (RFC 7785) to fetch resources that have changed in a more optimized manner. In base ALTO, a client must periodically re-fetch resources that have changed. Some resources served by an ALTO server (network maps, for instance) may be quite large, while the changes to the resources may be fairly localized, and can be served in an optimal manner (sending diffs, for instance) instead of having the client fetch the entire updated resource. This document adds the capability of sending localized diffs in ALTO. Working Group Summary ALTO incremental updates is a well known work to the ALTO working group. The initial work on this started in October 2014; the working group adopted the work in May 2015 [1], after which it has gone through about 19 revisions to the current version. The work is fairly mature and the design tradeoffs in coming up with an equitable solution to the problem described above are well documented in the draft. Document Quality There is one known implementation of this draft, this implementation is related to a paper titled "Steering Hyper-Giant's Traffic at Scale", published in the proceedings of ACM CoNEXT 2019 [9]. This implementation implements the JSON merge patch feature, with the general JSON patch being on their roadmap [10]. Personnel The document shepherd is Vijay K. Gurbani. The responsible Area Director is Mirja Kühlewind. _______________________________________________ alto mailing list [email protected] https://www.ietf.org/mailman/listinfo/alto
