Abstract: A device may be configured to receive, process, forward, and/or respond to one or more resource queries. For example, the device may determine whether multiple queries are satisfied by a multicast response. The device may receive a first query and a second query directed to a resource, The first and the second query may comprise a structure proxy rule identifier (sPRID). The device may determine the similarity between the two queries. For example, the similarity determination may be based on the sPRID of the two queries. The device may determine whether a response that satisfies the first query also satisfies the second query, which may be based on a response to the first query and information comprised within the sPRID of the two queries. If the response satisfies both queries, the device may multicast the response.

Abstract: Procedures, methods and architectures for anchoring communication between devices configured to operate in a first type of network in a second type of network or across a peer first type of network are disclosed. A first type of packet originating from a device in the first type of network may be encapsulated into a second type of packet and forwarded via the second type of network.

Abstract: Systems, methods, and instrumentalities are disclosed to communicate with subscribers in an information-centric networking environment. A WTRU may store a first path from the WTRU to a first subscriber and a second path from the WTRU to a second subscriber. A message from a topology manager may be received. The message may indicate a change to a network topology. In response to a determination that the change to the network topology relates to the first path and does not relate to the second path, the WTRU may remove the first path from the memory and maintain the second path in the memory. The WTRU may send a request to the topology manager for a third path to replace the first path that was removed from memory. In response to the above determination, a portion of the first path may be removed and replaced according to the above mechanism.

Abstract: A method and a first network access point (NAP) in an Information Centric Network (ICN) is disclosed. The first NAP is configured to receive a request for a Hypertext Transfer Protocol (HTTP) resource from a wireless transmit/receive unit (WTRU). The first NAP is configured to request the HTTP resource from a first server. The first NAP is configured to receive an error message. The error message may indicate that the HTTP resource is not available from the first server. The first NAP is configured to request the HTTP resource from a second NAP. The first NAP is configured to receive the HTTP resource from the second NAP. The first NAP is configured to send the HTTP resource to the WTRU.

Abstract: System and methods are described to register FQDN-based IP service endpoints at network attachment points. One embodiment takes the form of a method comprising: receiving, at a server-side network access point (sNAP) in an information-centric network (ICN), a registration request including a first fully qualified domain name (FQDN), a port, a transport protocol, and a service name of an IP server; publishing, at the sNAP, the port, the transport protocol, and the service name to a first content identifier (CID); and subscribing, at the sNAP, to a second CID that is based on the FQDN.

Abstract: A first network access point (NAP) of an Information Centric Networking (ICN) network may receive a request for a HTTP resource from a requestor. The first NAP may request the HTTP resource from a first server associated with a fully qualified domain name (FQDN). The first NAP may receive an error message that the HTTP resource is not available. The first NAP may publish a message to a rendezvous point (RVZ) including a list of excluded node identifiers (NIDs) of one or more NAPs that have not provided the HTTP resource. The first NAP may receive a forwarding identifier (FID) of a second NAP associated with the FQDN with a NID not on the list of excluded NIDs from a topology manager (TM). The first NAP may request the HTTP resource from the second NAP. The first NAP may receive the HTTP resource is and send it to the requestor.

Abstract: Content owners, origin servers, and other entities may wish to use elastic service provisioning to provide users improved service. For example, an origin server may wish to offload processing/network load to a surrogate server such that users of a service may experience improved performance. As another example, a content owner may wish to have content distributed to a number of surrogate servers to lower latency and improve bandwidth.

Abstract: Systems, methods, and instrumentalities are provided to implement a method for radio environment, measurement (REM) scheduling, information extraction, storage and processing to generate terrain and object mapping/identification using higher frequency radio signals, directional transmission techniques and external database information. Described are wireless transmit/receive units (WTRUs) comprising a processor configured to, when the WTRU is in an idle state, receive a common control channel from a millimeter wave base station (mB), decode a measurement schedule included in the common control channel, wherein the measurement schedule includes one or more slots during which sounding signals will be sent, and, determine a slot during which the WTRU is available to measure a sounding signal, and, when the WTRU is in a connected state, receive a dedicated control channel from a millimeter wave base station (mB), decode a measurement schedule and a receiver configuration included in the dedicated control channel, wherein the measurement schedule and the receiver configuration are specific to the WTRU, and wherein the measurement schedule includes one or more slots during which sounding signals will be sent, and determine a slot during which the WTRU is available to measure a sounding signal.
