The following errata report has been submitted for RFC8180, "Minimal IPv6 over the TSCH Mode of IEEE 802.15.4e (6TiSCH) Configuration". -------------------------------------- You may review the report below and at: http://www.rfc-editor.org/errata/eid5539 -------------------------------------- Type: Editorial Reported by: Yasuyuki Tanaka <yasuyuki.tanaka@inria.fr> Section: 5 Original Text ------------- (...) The Rank computation is described in Section 4.1 of [RFC6552]. A node's Rank (see Figure 4 for an example) is computed by the following equations: R(N) = R(P) + rank_increment rank_increment = (Rf*Sp + Sr) * MinHopRankIncrease (...) This section illustrates the use of OF0 (see Figure 4). We have: rank_increment = ((3*numTx/numTxAck)-2)*minHopRankIncrease = 512 Corrected Text -------------- (...) The Rank computation is described in Section 4.1 of [RFC6552]. A node's Rank (see Figure 4 for an example) is computed by the following equations: R(N) = R(P) + rank_increase rank_increase = (Rf*Sp + Sr) * MinHopRankIncrease (...) This section illustrates the use of OF0 (see Figure 4). We have: rank_increase = ((3*numTx/numTxAck)-2)*minHopRankIncrease = 512 Notes ----- s/rank_increment/rank_increase/ It'd be better to use "rank_increase" as the variable name for consistency, which is used in Section 4.1 of RFC 6552 (https://tools.ietf.org/html/rfc6552#section-4.1): [excerpt from RFC 6552] The step_of_rank Sp that is computed for that link is multiplied by the rank_factor Rf and then possibly stretched by a term Sr that is less than or equal to the configured stretch_of_rank. The resulting rank_increase is added to the Rank of preferred parent R(P) to obtain that of this node R(N): R(N) = R(P) + rank_increase where: rank_increase = (Rf*Sp + Sr) * MinHopRankIncrease Instructions: ------------- This erratum is currently posted as "Reported". If necessary, please use "Reply All" to discuss whether it should be verified or rejected. When a decision is reached, the verifying party can log in to change the status and edit the report, if necessary. -------------------------------------- RFC8180 (draft-ietf-6tisch-minimal-21) -------------------------------------- Title : Minimal IPv6 over the TSCH Mode of IEEE 802.15.4e (6TiSCH) Configuration Publication Date : May 2017 Author(s) : X.
