Abstract
In a LAN relaying/switching apparatus accommodating many LAN transmission lines, a controller performs a flow control which limits a data transmission for terminal portions which have inputted the data in which an output queue of a queue portion included in queue management module portions has exceeded a preset threshold value.
Claims17
A LAN relaying/switching apparatus comprising:
- a plurality of terminal portions for inputting data from an external apparatus;
- a queue management portion for performing an input/output management for a switch portion of the data;
- and
- a controller for performing a flow control which limits a data transmission for the terminal portions which have inputted the data which has caused an output queue of the queue management portion to exceed a preset threshold value.

A LAN relaying/switching apparatus comprising;
- a plurality of terminal portions for inputting data from an external apparatus;
- a queue management portion for performing an input/output management for a switch portion of the data;
- and
- a controller for performing a flow control which limits a specific data flow, from the terminal portions, which has caused an output queue of the queue management portion to exceed a preset threshold value.

A LAN relaying/switching apparatus comprising;
- a plurality of terminal portions for inputting data from an external apparatus;
- a queue management portion for performing an input/output management for a switch portion of the data;
- and
- a controller for identifying the terminal portions based on address information included in the data which has caused an output queue of the queue management portion to exceed each of a plurality of preset threshold values and for performing a flow control which limits a data transmission based on statistic information of a traffic amount for the identified terminal portion at the time when any one of the threshold values is exceeded.

A LAN relaying/switching apparatus comprising;
- a plurality of terminal portions including an ATM terminal portion for inputting data from an external apparatus;
- a queue management portion for performing an input/output management for a switch portion of the data;
- and
- a controller for transmitting an RM cell so as to limit a specific data flow from the ATM terminal portion when a data flow has caused an output queue of the queue management portion to exceed a preset threshold value is the specific data flow from the ATM terminal portion.
