Abstract: Technology for stateless forwarding of packets in an ICN is disclosed. Content routers modify a dynamic filter in an interest packet. In one aspect, a content router extracts a dynamic filter from an interest packet received on an ingress port and combines the dynamic filter with a local filter associated with the ingress port. The packet filter and the local filter may be combined without losing information in the packet filter or the local filter. A new filter may be inserted into the interest packet based on the combined packet filter and local filter. The interest packet having the new filter may be forwarded on an egress port. The data packet that returns the content object for the interest packet may be forwarded statelessly based on the dynamic filter. Thus, the data packet may be forwarded without use of a pending interest table (PIT).

Abstract: Data transmissions are scheduled from internet of things (IoT) user equipment (UEs) to a base station (BS) that serves those IoT UEs in a cellular network.

Each IoT UE can independently apply a mathematical operation to the broadcast information it receives to calculate and use the schedule. The BS can receive the data transmissions from each of the IoT UEs according to that schedule.

The data device then authenticates the user device and issues a decryption key derived from a private key corresponding to the public key, the first key, and the second key to the user device. The user device uses the decryption key to decrypt and access the data.

Abstract: An anchor server in an information-centric network (ICN) receives registration and deregistration requests from one or more producers in the ICN. In response to a producer initially registering, the anchor server stores records associating the producer with content available from the producer via a first point of attachment. In response to the producer deregistering, the records are marked as deactivated. While the records are deactivated, requests for the content from consumers may be queued. In response to the producer reregistering as being connected to the ICN via a second point of attachment, the queued requests are forwarded to the producer via the second point of attachment.
