Abstract: Methods and apparatus for efficiently transporting data through network tunnels. In one embodiment, a tunneled device advertises certain capabilities to peer devices of a network, and discovers capabilities of peer devices of the network. In a second embodiment, each device of a tunneled network derives a network parameter from a transit protocol parameter for use in data networking.

Abstract: Methods and apparatus for efficiently servicing isochronous streams (such as media data streams) associated with a network. In one embodiment, an Isochronous Cycle Manager (ICM), receives multiple independent streams of packets that include isochronous packets arriving according to different time bases (e.g., where each stream has a different time base). The packets are sorted by the ICM into a buffering mechanism according to their required presentation time. Additionally the ICM calculates a launch time for each packet. The NIC transmits the packets from the queue according to an access scheme, such as a time division multiplexed (TDM) scheme where each of a plurality of cycles is subdivided into time slots. During appropriate time slots, the NIC transmits the packets in chronological order, as read out of the buffering mechanism.
