1. A terminal device, comprising:

  • a query generator configured to generate, with respect to content comprising segments, a block query requesting at least two segments from among the segments, wherein the at least two segments are to be routed based on a content name of the content, the block query comprises the content name and a block range indicating the at least two segments;

    a table search processor configured to search, from a routing table, a content name which is longest-matched with the content name, and to determine a transmission direction of the block query, wherein the transmission direction comprises an output port, provided in the routing table, corresponding to the searched content name;

    a query transmitter configured to transmit the block query via the output port; and

    a content receiver configured to receive the at least two segments via an input port corresponding to the output port,wherein the query generator is further configured to increase a size of the block range in response that the at least two segments are received within a predetermined reception lifetime, to decrease the size of the block range in response that any of the at least two segments is not received within the predetermined reception lifetime, and to generate a new block query based on the adjusted size of the block range.
