IEEE 802.15.9-2016

This recommended practice defines a message exchange framework based on information elements (IE) as a transport method for KMP datagrams and guidelines for the use of some existing KMPs with IEEE Std 802.15.4(TM). This recommended practice does not create a new KMP. This recommended practice describes support for transporting KMP datagrams to support the security functionality present in IEEE Std 802.15.4. Significant in support of KMP transport is the definition of a general purpose multiplexed (MPX) data service supporting fragmentation, re-assembly, and protocol dispatch for payloads unable to fit in a single MAC frame. New IEEE Standard - Superseded. A message exchange framework based on information elements as a transport method for key management protocol (KMP) datagrams and guidelines for the use of some existing KMPs with IEEE Std 802.15.4 are defined in the recommended practice. A new KMP is not created in this recommended practice. In support of KMP transmission and reception, a generic multiplexed data service layer that can be used to transmit large packets from the upper KMP to another peer is also provided in this recommended practice. The multiplexed data service provides a fragmentation and multiplexing layer for those packets so they can be delivered over smaller MAC layer frames and multiplexed on the recipient end to the right processing service.
