Disclosed is a technology by which rules on communication permission or control are enforced to network internal devices such that an environment which looks as if to have a virtual firewall existing between network internal devices can be established. A communication control apparatus for this is located on the same level in the network as other devices are located. By using this communication control apparatus, an address resolution protocol (ARP) packet in which a data link layer address is manipulated is provided to devices that are the objects of communication cut-off, such that data packets transmitted by the communication cut-off object devices are transmitted to manipulated abnormal addresses. By doing so, communication with the communication cut-off object devices is cut off. For a device which is in a communication cut-off state although the device is not an object of communication cut-off any more, the communication control apparatus transmits an ARP packet including normal address information to the device such that the communication cut-off state is canceled.

Some base units may contain a telecommunications interface. Controller units may relay communications between themselves to reach a telecommunications interface. Controller functions located in different buildings may communicate. Controller functions may each receive wireless communications from a transponder and combine the received communications to reduce errors.

A two-way cable network offering high-speed broadband communications delivered via virtual private networks over a multi-channel shared media system. Bi-directional transmission of packet to ATM cell based communications is established between a head end communication controller and a number of subscriber terminal units, whereby individual cells are prioritized and routed according to a virtual connection. Virtual connections are organized to support multiple virtual private networks in a shared media CATV system. The virtual private network to which a particular STU belongs is user selectable and has the flexibility of handling multi up / downstream channels with different MAC domains. The present invention can also handle non-ATM MAC domains via the same common ATM switch.

In another embodiment, a user has the ability to select a quality of service that best suits the needs of the current application. In a further embodiment, the scheduling function is associated with each of the receivers in order to provide improved scalability.

Arbitration of multiple transponders, such as RFID tags, occurs in an interrogation field. The arbitration process is custom-tailored for individual applications, under software control, by the transponder reader or tag reader. Different wake-up slots are calculated for each tag during successive transmission cycles based upon the tag ID and the transmission cycle number. The tag reader may send a special fast read command to the tag which includes a read request and communications control parameters including the number of time slots for transponder communications, the number of transmissions that an individual transponder is allowed to issue, and the data rate at which the reader communicates to the transponder. The tag reader may also send a special command to a tag to read its data and cause the tag to become decoupled from the environment. Additional schemes are provided to halve the number of active tags in each transmission cycle and to selectively inactivate designated groupings of tag, thereby improving discrimination of the tags in the interrogation field. The tags may be selectively placed in either a tag-talk-first mode or a reader-talk-first mode.
