Abstract: A method of using ephemeral identifiers (IDs) in a network implemented a network element (NE) comprises obtaining ephemeral ID for at least one user equipment (UE) accessible by the NE, wherein the ephemeral ID is a temporary and recyclable ID associated with the UE, transmitting a request to map the ephemeral ID of the UE to a locator of the NE to a mapping server, and establishing a communication session between the UE and a network site using the ephemeral ID.

Abstract: A computer-implemented method of preventing communications based on endpoint category is provided that comprises: accessing, by one or more processors of a router, a data packet that indicates a source identifier that identifies a source endpoint and a destination identifier that identifies a destination endpoint; determining, by the one or more processors of the router, a source category based on the source identifier; determining, by the one or more processors of the router, a destination category based on the destination identifier; and based on the source category and the destination category, refraining from sending the data packet to the destination endpoint.

Abstract: A computer-implemented method of monitoring communication flows between identities is provided that comprises: accessing a first data packet that indicates a source identifier, a destination identifier, a first source locator, and a first destination locator; accessing a second data packet that indicates the source identifier, the destination identifier, a second source locator, and a second destination locator, the second destination locator being different from the first destination locator; storing data regarding the first data packet and the second data packet in a single ID flow record based on a determination that the source identifier of the first data packet matches the source identifier of the second data packet and a determination that the destination identifier of the first data packet matches the destination identifier of the second data packet; and based on the single ID flow record, adjusting a resource allocation.
