LS to IETF Operations and Management Area WG (OPSAWG) regarding use of MUD to indicate network usage requirements in cellular networks.
|From Contact||Paul Gosden|
Operations and Management Area Working Group Discussion List
|Deadline||2018-06-07 Action Needed|
1 Summary GSMA TSGIoT is studying options for keeping track of how IoT devices and IoT applications make use of the cellular network, so that network operators may both adapt resource allocation based on the device’s anticipated needs, as well as detect anomalous behavior that deviates from those needs, and take appropriate action to protect the network and customer. An overview of IETF MUD was submitted for consideration in this context and there was interest both in studying MUD’s usage in a cellular network over TCP/IP after the data connection is established, as it is defined today in its current draft, and also exploring together with IETF OSAWG the possibility of leveraging MUD during the initial provisioning of an IoT device onto the 3GPP network, well before it ever attempts to establish an IP data connection. This study item could possibly lead to extensions such as an alternative delivery of the MUD URI to the network, alternate retrieval of the MUD file, and possibly extensions to YANG-NETCONF to express cellular-specific resource requests, and we would like to engage with IETF OPSAWG to explore the possibilities. 2 Request for Action GSMA TSGIoT kindly requests a reply from IETF OPSAWG indicating your interest in discussing this further in a joint conference call. If you can indicate who would be interested in having a call we will set up a Doodle poll to find a suitable date and time. 3 Contact In the case of any questions and/or feedback these can be directed to Paul Gosden Terminals Director, looking after TSG and TSGIoT groups [firstname.lastname@example.org]. 4 Next Meetings GSMA TSGIoT#08 Meeting 7th June 2018 Conference Call
