Hi Michael, According to my understanding, there are two levels of synchronization in 6TiSCH network, i.e. (1) all nodes work on same ASN, which is presented in EB; (2) the node corrects its clock periodically by communication with its timesource. The description in TimeSource is about (2). make sense? ThanksQin

Make sense? I don't see how container TimeSource will give me a list of parents. leaf NodeAddress { type nodeaddresstype; description "Specifies the address of selected time source neighbors."; } I think that the plural in the description, "neighbors" suggests that there is a list, but I don't see that would be the case here. I see how this affects the source of ASN, but not how it provides a list of parents. It's not obvious to me that the RPL parent is by definition the best source for the ASN; and the policy definition here would suggest that there are other criteria. I suggest changing: "specify the timesource selection policy and some relative statistics. "; to: "specify the timesource (ASN) selection policy and some relative statistics. "; just so that it shows up on when searching for ASN. -- Michael Richardson <mcr+i...@sandelman.ca>, Sandelman Software Works -= IPv6 IoT consulting =-
