1. A proximity control method for transmitting content from a source node to a destination node, the method comprising:
- receiving or relaying a content request from the destination node; and
performing, at each node in a link from the source node to the destination node, a proximity control mechanism based on whether the transmitting is in a single proximity control (SPC) domain, a mixed proximity control (MPC) domain, or a network-based service domain, and based on a physical distance with respect to a neighboring node, whereinthe SPC domain comprises a relay node,the relay node functions as a switched network in the SPC domain and the relay node comprises an Audio/Video Bridge (AVB), and the AVB comprises a second Digital Transmission Content Protection (DTCP) which utilizes a first Digital Transmission Content Protection (DTCP) as an initial reference model, and an Internet Protocol (IP) comprises the first Digital Transmission Content Protection (DTCP), andthe second Digital Transmission Content Protection (DTCP) comprises a standard carrying out wireless local area network communication in any one of domains of the second Digital Transmission Content Protection (DTCP) when the second Digital Transmission Content Protection (DTCP) has a proximity probability to a layer 2 (L2).

Abstract
A proximity control method for transmitting a content and a network node using the proximity control method is provided. A proximity control method for transmitting a content performs a different proximity control mechanism depending on each of a single proximity control (SPC) domain, a mixed proximity control (MPC) domain, and a network-based service domain, and each of nodes performs the different proximity control mechanism based on a physical distance from a neighboring node, the nodes being comprised in the SPC domain, the MPC domain, and the network-based service domain.

10. A network comprising:
-
a plurality of nodes on a link, each node including a proximity validity checker processor configured to check proximity validity with either a previous node of the plurality of nodes or a subsequent node of the plurality of nodes in a link to receive a content, wherein the proximity validity checker processor is configured to perform the proximity validity checking based on whether the node is in a single proximity control (SPC) domain, a mixed proximity control (MPC) domain, or a network-based service domain, and based on a physical distance with respect to a neighboring node, the proximity validity checker checks the proximity validity by utilizing a physical distance as a proximity parameter, the physical distance being measured by using a distance measurement scheme, and the distance measurement scheme comprises a second Digital Transmission Content Protection (DTCP) which utilizes a first Digital Transmission Content Protection (DTCP) as an initial reference model, and an Internet Protocol (IP) comprises the first Digital Transmission Content Protection (DTCP). - View Dependent Claims (11, 12)
