Abstract

A method for retrieving content on a network comprising a first device and a second device is described. The method includes receiving in the network a request for content from the first device, the request identifying the content using an IPv6 address for the content, and determining whether the content is stored in a cache of the second device. Upon determining the content is stored in the cache of the second device, a request is sent to the second device for the content using the IPv6 address of the content. The content is forwarded to the first device from the second device, wherein the first and second devices are part of the same layer 2 domain. Methods of injecting content to a home network and packaging content are also described.

First claim

What is claimed is:

1 . A method for retrieving content on a network comprising a first device and a second device, the method comprising:
receiving in the network a request for content from the first device, the request identifying the content using an IPv6 address for the content; determining whether the content is stored in a cache of the second device and, upon determining the content is stored in the cache of the second device, sending a request to the second device for the content using the IPv6 address of the content; forwarding the content to the first device from the second device; wherein the first and second devices are part of the same layer 2 domain.

2 . The method according to claim 2 , wherein the first device and the second device are connected to the same home network.

3 . The method according to claim 2 , further comprising sending the request for content using the IPv6 address to a content server on the home network.

4 . The method according to claim 1 , wherein the network determines a route for delivering the content to the first device via devices which are capable of caching and/or delivering the content and the content is forwarded to the first device using this route.

5 . The method according to claim 2 , wherein the content comprises a plurality of chunks and the first device receives chunks of the content from more than one device and/or content server.

6 . The method according to claim 1 , wherein the content comprises two or more chunks and the network receives a request for a plurality of chunks of the content.

7 . The method of claim 6 , wherein the first device receives a first chunk of the content from the second device and a second chunk of the content from another device.

8 . A method for injecting content to a home network, the method comprising:
sending content to a router in a home network for storing in the home network, wherein the content has an associated IPv6 address, the IPv6 address comprising an identifier of the content; storing the content in a storage device in the home network; advertising a route to the IPv6 address of the content stored in the storage device.

9 . The method according to claim 8 , wherein the content sent to the router in the home network is selected based on content previously accessed by one or more devices connected to the home network.

10 . The method according to claim 8 , wherein the content is injected in home network from an Over the Top (OTT) provider.

11 . A method of packaging content, the method comprising:
receiving content in a home network; generating at least one content package from the received content; wherein each content package comprises an IPv6 address having a first part comprising a prefix identifying the home network and a second part comprising an identifier of the content.

12 . The method of claim 11 , wherein receiving content in a home network comprises receiving a stream of content or reading content from a content file.

13 . The method of claim 12 , wherein the prefix identifying the home network comprises a global IPv6 prefix or Unique Local Address prefix for the home network.

14 . The method of claim 13 , wherein the global IPv6 prefix or Unique Local Address prefix is received from a connected ISP.

15 . The method of claim 11 , further comprising calculating the second part of the IPv6 address comprising an identifier of the content based on parameters associated with the content.
