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

Hi Michael, Regarding to including DAG rank into 6top NeighborList, I think,  besides RPL, there may be other routing protocols working on top of 6top in the future. Thus, it could be better to decouple 6top sublayer and upper layer protocol like RPL. What do you think?  What other people think?

Hi Pascal, What you say is that the RPL parents list should be in RPL data model (YANG model), and 6top data model only includes the parent used as time source. Right? It really makes sense to me. ThanksQin On Thursday, June 11, 2015 12:45 AM, Pascal Thubert (pthubert) wrote: #y

Hi Pascal. If we move ahead with the solution discussed between myself and Alexander, aliases won’t save much space and are not worth it. The solution is based on the following principles: · Data nodes are identified using a 20 bits registered module identifier and a 10 bits assigned Y

Hello Qin: A node has a list of RPL parents per RPL instance. But that’s a RPL problem and we probably need a RPL data model to be done at ROLL. OTOH, there is one (or more?) RPL instance that is used for 6TiSCH timing. I think all we need in 6top is an information of which RPL instance(s) is (a

Dear all: This looks like the problem of local namespaces, which is the reason why MPLS switches labels. The user may access a limited set of resources from a number of servers, and servers are read by many users. You cannot ensure that you have a single alias space that satisfies them all. So
