Abstract
In a cell assembling method and device for packets received from a plurality of input ports, packets received from e.g. four input ports are respectively stored in packet buffers. By sequentially and cyclically providing a read request to the packet buffers at regular intervals, the packets per fixed length data are sequentially and cyclically read. Then, by capsulating the fixed length data read (any one of fixed length data), the data is converted into e.g. an ATM cell. Alternatively, based on cell assembling information (any one of cell assembling information synchronized with fixed length data), e.g. an ATM header is generated to be used for a conversion into the ATM cell.
Claims19
A cell assembling method comprising:
- a first step of storing packets received from a plurality of input ports in buffers provided corresponding to the input ports;
- a second step of reading the packets per fixed length data from the buffers by sequentially providing a read request to the buffers;
- and
- a third step of converting the fixed length data into cells.
A cell assembling method comprising:
- a first step of storing packets received from a plurality of input ports in buffers provided corresponding to the input ports;
- a second step of dividing the packets from the buffers into data of a start, an end, and an intermediate portion to be sequentially read;
- and
- a third step of adding to the divided data inter-layer adjustment information necessary for capsulation to an upper layer, corresponding to a size of the divided data read at the second step and of converting the divided data into cells.
A cell assembling device comprising:
- a first means storing packets received from a plurality of input ports in buffers provided corresponding to the input ports;
- a second means reading the packets per fixed length data from the buffers by sequentially providing a read request to the buffers;
- and
- a third means converting the fixed length data into cells.
