Abstract

A network traffic managing node of a local area network, such as a router or gateway, can implement a network discovery and remote access mechanism for the local area network. A catalog of a plurality of files stored in a plurality of network devices of the local area network is created at the network traffic managing node based, at least in part, on information associated with the plurality of files determined using a network discovery procedure. The catalog of the plurality of files is provide to a remote network node of a wide area network in response to receiving a message from the remote network node requesting access to the plurality of files. One or more files are provided to the remote network node in response to receiving a message from the remote network node requesting the one or more files from the catalog of the plurality of files.
