Abstract
A packet multiplexing control method and equipment using the method are realized by a simple control method with reduced hardware, enabling to provide low cost, efficient and fair bandwidth control corresponding to traffic characteristic of users. The packet multiplexing control method includes the steps of extracting a header part in each packet data received from a plurality of terminals; learning an address in the extracted header part; and controlling either admission processing or discard processing of the received packet according to the result of learning the address.
Claims9
A packet multiplexing control method comprising the steps of:
- extracting a header part in each packet data received from a plurality of terminals;
- learning an address in the extracted header part;
- and
- controlling either admission processing or discard processing of the received packet according to the result of learning the address.
A concentrator for multiplex-controlling packets received from a plurality of terminals to output, comprising:
- a header extractor for extracting a packet header part in each packet received from a plurality of terminals;
- an address learning portion for learning the address in the extracted header part;
- and
- a discard controller for controlling to admit or discard the received packet according to the address learning result obtained by the address learning portion.
A network comprising:
- a plurality of terminals:
- and
- a plurality of concentrators, which are allocated hierarchically for multiplex-controlling packets received from the plurality of terminals to output,
- wherein each of the plurality of concentrators includes;
- an extractor for extracting a header part in each packet received from a plurality of terminals,
- an address learning portion for learning an address in the extracted header part, and
- a discard controller for controlling to admit or discard the received packet according to the address learning result obtained by the address learning portion, and
- wherein address information having been learned in a concentrator located on the upstream side is notified to a concentrator located on the downstream side.
