Introduction Lisp-Nexagon is a geospatial intelligence network protocol designed to support physical-world applications such as transportation, public safety, and logistics. It combines the Locator/ID Separation Protocol (LISP) with the [H3] spatial indexing system to enable distributed agents to report, aggregate, and disseminate geospatial state information. The system models geospatial data flow and control after the management planes found in digital infrastructure. Geospatial intelligence is organized by H3 tiles at varying resolutions. High- resolution (small-area) tiles are used to represent specific environmental and infrastructural conditions such as road status, vegetation coverage, fire activity, weather, and physical obstructions. Data for these tiles is produced by interoperating sources and collected by geo-aggregation agents. Each aggregation agent is assigned a low-resolution (large-area) H3 tile that defines its jurisdiction. This jurisdiction is associated with a LISP Endpoint Identifier (EID), which acts as the routing and addressing point for intelligence updates. Agents receive input from data sources within their jurisdiction and provide processed information or notifications to clients authorized to query or subscribe to state data. Lisp-Nexagon provides a framework for structured, addressable, and jurisdiction-based geospatial coordination using existing LISP mechanisms and H3 spatial semantics. Barkai, et al. Expires October 1, 2025 [Page 3] Internet-Draft LISP April 2025 The network requires a formal provisioning step for sources, clients, and agents. For sources and destinations, this step involves an authentication, authorization, and accounting (AAA) procedure through which endpoints request and renew EIDs and LISP tunnel-routers (XTR) to interact through. ___ / \ EID >> States >> EID Upload \ ___ / Channels /\ Functions() \/ Figure 1:H3-LISP Agents Off-Peak EID Condensed Allocation _ _ _ _ / \/ \ / \/ \ n+1 \_/\_/ \_/\_/ ---- Peak allocation for same EID / \/ \ / \/ \ ---- Spread on more compute locations \_/\_/ \_/\_/ ---- _ _ _ _ _ _ _ _ n+1 / \/ \ / \/ \ ---- / \/ \ / \/ \ / \/ \ / \/ \ ---- \_/\_/ \_/\_/ ---- \_/\_/ \_/\_/ \_/\_/ \_/\_/ ---- / \/ \ / \/ \ ---- / \/ \ / \/ \ / \/ \ / \/ \ ---- \_/\_/ \_/\_/ ---- \_/\_/ \_/\_/ \_/\_/ \_/\_/ ---- Site Site Site Site Site Site Figure 2: Dynamic allocation per activity Barkai, et al.

Definition of Terms Based on [RFC9300][RFC9301] H3AgentEID: H3AgentEID is an EID-addressable Geolocation agent, also known as a nexagon. It serves as a designated destination for Geolocation aggregation and an (S,G) source of multicast themed channels. It has a LISP data-plane stack to encapsulate packets via ServerXTR. ServerXTR: ServerXTR is a data-plane only LISP protocol stack implementation that is co-located with the H3AgentEID process. It encapsulates and decapsulates packets to and from EdgeRTRs. MobilityClient: MobilityClient is an application that may be a part of a driving system or mobility application, It has a LISP data- plane stack to encapsulate packets via ClientXTR. MobilityClientEID: MobilityClientEID is the IPv6 EID used by Mobility Clients. The destination of such packets are H3AgentEIDs. The EID is assigned as part of the MobilityClient network AAA. ClientXTR: ClientXTR is a data-plane only LISP protocol stack implementation co-located with the Mobility Client application. It encapsulates and decapsulates packets to and from EdgeRTRs. EdgeRTR: The EdgeRTR network is responsible for connecting Mobility Clients to Agents and managing MobilityClientEIDs multicast registrations [RFC8378]. The network achieves this by using encapsulation to aggregate Mobility Clients and Geolocation Agents, making it easier to access the mobility network from hosting providers and mobile providers. The RTRs within the EdgeRTR network re-encapsulate packets from ClientXTRs, ServerXTRs, and remote RTRs. During packet decapsulation, EdgeRTRs glean H3 agent EIDs and MobilityClientEIDs and store them along with route locations (RLOCs) in map-caches. These mappings are then registered to the LISP mapping system [RFC9301] and are provisioned when Geolocation Agents are assigned to EdgeRTRs. It's key to note that EdgeRTRs do not register MobilityClientEIDs. Enterprises can provide their own EdgeRTRs to protect the geo-privacy. Barkai, et al.

The AAA procedure described below can be used as an example for obtaining EIDs and EdgeRTRs, and for enabling the use of the network. Diameter [RFC6733] based AAA can be used: 1) obtain the address of the mobility-network AAA using DNS 2) obtain MobilityClientEIDs and EdgeRTRs from AAA procedure 3) renewed periodically from AAA while using the network MobilityClient DomainNameServer AAA Server MobilityEdgeRTR | | | | | lookup AAA Server | | | |------------------->| | | |<-------------------| | | | AAA Server IP | | | | | | | | Client identifier and credentials | | |--------------------------------------->| | | | |Provision Client EID| | | |------------------->| | | |<-------------------| | | | Ack Provisioned EID| | Send ClientEID,EdgeRTR RLOC | | |<---------------------------------------| | . . .

Expires October 1, 2025 [Page 7] Internet-Draft LISP April 2025 4. Clients-Agents Networking The mobility network functions as a standard LISP overlay that delivers unicast and multicast packets across data plane XTRs, which are used in the stack of each mobility client and server. ClientXTRs and ServerXTRs are associated with EdgeRTRs, which allows MobilityClients to "show up" at any location within the mobility network, regardless of the network provider or network address translation domain. This structure also enables any H3 agent EID to be instantiated, delegated, or failed over to any compute location. In this specification, we assume a semi-random association between ClientXTRs and EdgeRTRs assigned by the AAA procedure, with a pool of EdgeRTRs, which can be dynamically allocated, distributing the load of MobilityClients within a given metro area. We also assume that EdgeRTRs are topologically equivalent and use LISP to encapsulate traffic to and from other EdgeRTRs. It is possible for there to be more than one ClientEID in the same process using the same ClientXTR. The implementation of such multiplexing is not specified.

We use [RFC8378] signal-free multicast to implement overlay channels. Mobility-networks have many channels with thousands subscribers each. MobilityClients driving through/subscribing to an h3.rB area issue group address report based on any mechanism supported by [RFC8378]. Example report formats are specified in [RFC4604].

All information is conveyed to clients using provisioned Geolocation agents. MobilityClients receive information only via geospatial channels originating at provisioned agents, replicated by EdgeRTRs. All traffic is carried over encrypted encapsulation. 7. Privacy Considerations In the mobility network, MobilityClients obtain temporary clientEIDs and RLOCs of EdgeRTRs through an AAA process in order to access the network for a certain period. The interface between MobilityClients and EdgeRTRs is the most sensitive from a privacy perspective, as the EdgeRTR can determine the client RLOC and the h3.rB area that the client is engaged with based on header information, even though the traffic on this interface is tunneled and the detection content is encrypted between ClientXTR and EdgeRTR. Enterprises such as vehicle OEMs or carriers can use their own EdgeRTRs (BYO_RTRs), which are pre-provisioned to use the mapping system and are approved by other EdgeRTRs. Beyond the client to EdgeRTR hop, the mapping system does not hold MobilityClientEID information and remote EdgeRTRs are only aware of clients' temporary EIDs. H3AgentEIDs decrypt and parse actual h3.rS detections, taking into account MobilityClientEID credentials encoded in the client EID and assigned by AAA to avoid poorly made or localized detections. In summary the privacy risk mitigations are: (1) tapping: all communications are through tunnels therefore may be encrypted using IP-Sec or other supported point to point underlay standards. (2) spoofing: it is very hard to guess a MobilityClientEID valid for a short period of time. Clients and H3Agents EIDs are provisioned in EdgeRTRs, Clients using the AAA procedure, H3Agents via dev-ops. (3) credibility: the interface crowd-sources and does not assume to trust single detections. Credit history track MobilityClient aggregate scores from all agents are delivered to AAA subsystem (4) geo-privacy: Only EdgeRTRs are aware of both clients' RLOC and geo-location, only AAA is aware of client IDs credentials and credit but not geo-location. Ongoing client credit adjustments span all H3Agents administratively to AAA without specific geo-source. Barkai, et al. Expires October 1, 2025 [Page 16] Internet-Draft LISP April 2025 8.
