Dear CoRE WG,



We have submitted a new document draft-tiloca-core-groupcomm-proxy:



https://tools.ietf.org/html/draft-tiloca-core-groupcomm-proxy-00



The document details the operations of forward-proxies supporting CoAP

group communication and addresses the issues identified in [1]. In particular,

a client can send a unicast CoAP group request to the proxy including a new

Option to indicate to the proxy the time period to collect responses. Also a

new Option is included in the server’s responses to enable the client to

separate and identify the multiple responses it receives via the proxy.



Comments are very welcome!



Best regards

Esko
