Problems solved by technology

The disadvantage is that when the data traffic is concentrated, the delay caused is relatively large
[0009] All the above methods have a common shortcoming: no matter what the data traffic is, the update mechanism works as before. When the data traffic is frequent, a certain number of entries must be updated within the specified time. in this way
The result of this is that when the data traffic is frequent, it still takes a certain amount of processor time, so that the processing delay of the data traffic increases periodically, and even pauses

Embodiment Construction

[0020] The method for updating the large-capacity storage table of the present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0021] Take the implementation of network address translation (NAT) on communication equipment as an example: in the process of implementing network address translation, when data packets access the public network from the private network, since the public network does not support private addresses, it is necessary to The address (and port) is converted to a certain extent, and when the response message data is received, the destination address is converted to the original private network address, and the conversion table entries used must be maintained during this process. This entry has a certain life cycle. In a given period, if no data is used for this entry, it must be cleared to release the resources it occupies for other transformations. At this time, a traversal update me...

Abstract

A method for updating the storage list includes determining the average ergodic period of storage list and the upper limit of the number of list terms to be updated at the same time, receiving a data and recording its arrival time, calculating the number of list terms to be updated this time, setting up it to the upper limit if it is higher then upper limit, and updating the list term. Its advantage is equalizing system load.

Description

Technical field [0001] The invention relates to a method for updating a storage table, in particular to a fast and effective method for updating entries of a large-capacity storage table. Background technique [0002] With the rapid development of the Internet network, the continuous advancement of network technology, and the continuous emergence of high-performance network equipment, the use of software to process network data is flexible, low-cost, high-output, and low-development cycle. And occupy a place, enduring. Faced with the massive and sudden nature of data, compared with hardware processing, pure software processing has a high degree of intelligence, but the processing speed is quite different from hardware processing. Efficient methods need to be adopted, which are convenient and convenient. The process can greatly narrow the gap between the two. [0003] In the process of software processing, most of them have one thing in common, that is, a large-capacity sto...
