Abstract

Systems, methods, and instrumentalities are disclosed for providing Information Centric Networking (ICN) within a network, comprising detecting a request for content from a wireless transmit/receive unit (WTRU) that is in the network, selecting a network element for the WTRU to attach to, wherein the network element is selected without regard to properties of the content requested, and providing the content to the WTRU. A request to publish content from a WTRU in the network may include determining, based on content name, whether to publish the content in the network or outside the network, and if the content is to be published in the network, selecting a network element for the WTRU to attach to, wherein the network element is selected without regard to properties of the content requested, and causing the network element to accept the content from the WTRU.

Claims

1-82. -82. (canceled)

83. A method for providing Information Centric Networking (ICN) within a network, comprising:

detecting a domain name server (DNS)-based request for content from a wireless transmit/receive unit (WTRU);

selecting a network element for the WTRU to attach to, wherein the network element is selected without regard to properties of the content requested;

establishing an Internet Protocol (IP) session between the network element and the WTRU, wherein the WTRU is anchored at the network element;

redirecting the DNS request for content to an ICN node; and

providing the content to the WTRU through the selected network element.

84. The method of claim 83, wherein detecting includes establishing a DNS proxy or a DNS server to intercept or receive the DNS request.

85. The method of claim 83, wherein the network element delivers the content to the WTRU using a TCP socket or a UDP socket.

86. The method of claim 83, wherein the network element accepts the request for content using IP protocol, receives the content using ICN protocol, and delivers the content to the WTRU using IP protocol.

87. The method of claim 83, further comprising specifying the content with a domain name.

88. The method of claim 87, further comprising specifying the level of service for the domain name.

89. The method of claim 83, wherein selecting the network element is based upon at least one of load information, the WTRU'"'"'s location, or expected traffic requirements.

90. The method of claim 83, further comprising dynamically distributing the content across a plurality of nodes.

91. The method of claim 83, wherein providing includes retrieving content that is cached in the network.

92. The method of claim 83, wherein providing includes communicating with an application service provider to receive the content.

93. A network element for providing Information Centric Networking (ICN) within a network, comprising:

a processor configured to;

receive instructions to attach to a wireless transmit/receive unit (WTRU) that is requesting content and establish an Internet Protocol (IP) session, wherein the network element is selected without regard to properties of the content requested;

accept a domain name server (DNS)-based request for content from the WTRU;

redirect the DNS request for content to an ICN node;

receive the content from the ICN node; and

provide the content to the WTRU.

94. The network element of claim 93, wherein the WTRU is anchored to the network element for the duration of the IP session.

95. The network element of claim 93, wherein the network element is selected based upon at least one of load information, the WTRU'"'"'s location, or expected traffic requirements.

96. The network element of claim 93, wherein the network element accepts the request for content using IP protocol, receives the content using ICN protocol, and delivers the content to the WTRU using IP protocol.

97. The network element of claim 93, wherein the network element delivers the content to the WTRU using a TCP socket or a UDP socket.

98. A network server for providing Information Centric Networking (ICN) within a network, comprising:

a processor configured to;

detect a domain name server (DNS)-based request for content from a wireless transmit/receive unit (WTRU);

establish a DNS proxy or a DNS server to intercept or receive the DNS request;

select a network element for the WTRU to attach to, wherein the network element is selected without regard to properties of the content requested;

instruct the network element to establish an Internet Protocol (IP) session with the WTRU, wherein the WTRU is anchored at the network element;

redirect the DNS request for content to an ICN node; and

provide the content to the WTRU through the selected network element.

99. The network server of claim 98, wherein the network element is selected based upon at least one of load information, the WTRU'"'"'s location, or expected traffic requirements.

100. The network server of claim 98, wherein the processor is further configured to dynamically distribute the content across a plurality of ICN nodes.

101. The network server of claim 98, wherein the processor is further configured to retrieve content that is cached in the network.

102. The network server of claim 98, wherein the processor is further configured to communicate with an application service provider to receive the content.
