  • Publication number: 20190199540
    Abstract: Employing proxy rule identifiers to ensure the integrity of content delivered over an HTTP-over-ICN system. An exemplary method is performed by a client-side network attachment point (cNAP) on an information-centric network (ICN). The cNAP receives an HTTP request that includes a resource identifier and at least one header field. The cNAP generates a proxy rule identifier (PRID) based on the header field(s) and a content identifier (CID) based on the resource identifier. The PRID may be generated by applying a hash function to a string that includes header field data. The cNAP sends an outgoing ICN message that includes the CID and the PRID. In response, the cNAP receives an incoming ICN message that includes an HTTP response, a PRID, and a CID. The cNAP and directs the HTTP response to the appropriate client(s) based on the PRID and CID.

  • Publication number: 20180367327
    Abstract: Some embodiments include systems, methods, and devices for enabling communication between at least two internet protocol (IP)-only wireless transmit/receive units (WTRUs), at least one of which is connected to an information centric network (ICN). The WTRU may send a generic attribute registration multicast registration protocol (GMRP) request on a local IP link to an information centric network (ICN) network attachment point (NAP). The NAP may receive and register the GMRP request with an internal database (DB) along with an IP multicast address entry matching the GMRP request. The WTRU may then send an IP multicast packet to the NAP for dissemination to an IP multicast group over an ICN by encapsulating the IP multicast packet in an ICN packet.

  • Publication number: 20180198684
    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.

  • Publication number: 20180007116
    Abstract: Methods and systems anchor hypertext transfer protocol (HTTP) level communication in an information-centric networking (ICN) network. Both content requests and responses to servers within the ICN network and to servers located outside the ICN network, in an IP network for example, are disclosed. Communication may be between two IP capable only devices at the HTTP level, one connected to an ICN network while the other one is connected either to an ICN or IP network. The disclosed namespace 200 enables IP based HTTP communication within the ICN network. An information-centric networking (ICN) network attachment point (NAP) or border gateway (BGW) may receive an HTTP request packet and encapsulate the received HTTP request packet. The ICN NAP/BGW may then forward the HTTP request packet towards the local ICN network servers. The HTTP request packet may be published to a named content identifier (CID) that may be determined through a hash function of a fully qualified domain name (FQDN).

  • Publication number: 20170277806
    Abstract: A method and network access point (NAP) capable of serving content to a requesting wireless transmit/receive unit (WTRU). The NAP receives a request for content from the WTRU via an air interface associated with the NAP. The requested content is associated with an allowable latency. The NAP determines whether the requested content is cached locally at the NAP. On a condition that the requested content is not cached locally at the NAP, the NAP determines delay metrics associated with obtaining the requested content from a centralized cache and at least one neighboring NAP. The NAP selects the centralized cache or the at least one neighboring NAP to retrieve the requested content from based on the delay metrics and the allowable latency associated with the requested content. The NAP then transmits the requested content to the WTRU over the air interface.

  • Publication number: 20170048347
    Abstract: Methods, apparatuses and systems may be used to populate and utilize content in distributed network attachment point (NAP) caches with the help of a statistical cache report synchronization scheme that may be tuned in terms of bandwidth consumption for the synchronization and overall surety of the retrieval requests, and therefore, the incurred penalty in terms of latency. One example references a particular statistical synchronization scheme based on a Bloom filter reconciliation set technique. Each NAP of a plurality of NAPs may receive a list of unique NAP identifiers (NAPIds) of neighboring NAPs at regular intervals. A first NAP may receive a first content request for a requested content. On a condition that the requested content is not located in a caching database of the first NAP, the first NAP may determine the NAPId of a second NAP likely holding the requested content and issue a content request.
