    Abstract: A routing device includes a routing table. The routing table has a set of entries, each entry including: a content name attribute containing a content name value identifying a content, a faces attribute containing a faces value identifying a set of devices storing data related to the content name value, and a mask type attribute containing a mask type value identifying a type of mask to be used for performing a routing table lookup. The routing device is configured to perform a routing table lookup, the routing table lookup including the use of the mask type value of an entry to determine a covering relation between the content name value of the said entry and a content name value to be searched. The routing device is further configured to update the routing table depending on the determined covering relation.

    Abstract: Embodiments of the present invention include a method and apparatus for reducing control signaling overhead in a hybrid wireless network. The method comprises receiving a wireless frame in the hybrid wireless network at a first terminal, and determining whether the received wireless frame is a control frame for a wireless channel reservation; if the received wireless frame is a control frame for the wireless channel reservation, reading by the first terminal a value of Duration field in control frame, and updating a timer for a channel reservation period in the first terminal with the value of Duration field, instead of updating network allocation vector of the first terminal; determining whether the remaining time of the timer for the channel reservation period is longer than the time required for transmitting the data frame or not before transmitting a data frame by the first terminal; and transmitting the data frame directly by the first terminal without transmission of a control frame for the wireless channel reservation if the remaining time is longer than the time required for transmitting the data frame.
