Description
Technical field
The present invention relates to data communication field, relate in particular to a kind of realization ethernet switching device method for saving energy and ethernet switching device.
Background technology
Along with the development of Ethernet (Ethernet) technology, its operating rate is brought up to present 10G by initial 10M, makes Ethernet not only can satisfy the demand of local area network (LAN), and can bear the construction of extensive long-range network such as wide area network and metropolitan area network.Ethernet switching device is also more and more universal in networking, and internet (Internet) is gone up nearly all information all from interconnective Ethernet at present.
High more its desired power of the operating rate of Ethernet is also just high more.And the Ethernet in the reality such as a lot of local area network (LAN)s and be set to the server that whole day is awaited orders, all is in idle condition in the most of the time, only has the flow of several seconds or several hrs bigger.The existing Ethernet switching equipment all has more than a kind of operating rate usually, after the link of their ports is set up, will keep a certain special speed work, is generally the total flank speed of both link ends.Even under the very low situation of data traffic, Ethernet possibly still keep higher operating rate, if ethernet switching device keeps very high operating rate always, its utilance is reduced, and can cause waste of electric energy.

A kind of ethernet switching device comprises exchange chip, processor and physical chip, and said exchange chip comprises at least one port, and each port all has a counter, and said counter is used for adding up its corresponding port transmitting-receiving bag number;
Condition that said processor is used for being provided with needs energy-conservation port, change operating rate and the operating rate when eligible; The value of the counter that each port of zero clearing is corresponding; Periodically read the value of said counter; Judge whether said counter corresponding port meets the condition that changes operating rate; And be that it disposes new operating rate when port meets the condition that changes operating rate.
Said processor also is used for being provided with the cycle of reading the corresponding counter of the energy-conservation port of said needs.
A kind of realization ethernet switching device method for saving energy may further comprise the steps:
Step 1: the condition that needs energy-conservation port, change operating rate and the operating rate when eligible are set;
Step 2: the value of the counter that the energy-conservation port of the said needs of zero clearing is corresponding, and add up the transmitting-receiving bag number of the energy-conservation port of said needs;
Step 3: the value that periodically reads the corresponding counter of the energy-conservation port of said needs; And compare with the condition of said step 1 setting; If meet said condition, then the operating rate of corresponding port is configured to said operating rate when eligible, execution in step two; Otherwise, direct execution in step two.
Said step 1 also comprises: the cycle of reading the corresponding counter of the energy-conservation port of said needs is set.
Compared with prior art; The present invention judges through the count results of the counter of exchange chip whether port need change operating rate; And when eligible, the operating rate of corresponding port is arranged to suitable value; Thereby realized the energy-conservation of ethernet switching device, saved power consumption, reduced the operation cost of equipment.
The method of the invention is applicable to the ethernet switching device with multiple operating rate.
