Method and device and system of domain name server (DNS) for buffering updating
The invention discloses a method, device and system of a domain name server (DNS) for buffering updating. The method and device and system of the DNS for buffering updating comprise main contents as following: Regarding to any of echo reply message reserved in the DNS, effective buffering time which is corresponding to the echo reply message is confirmed when the echo reply message starts to be buffered. Time duration that the echo reply message is currently reserved in the DNS is confirmed, when the difference between the effective buffering time and the time duration is greater than zero and less than a preset updating duration, and a process that the echo reply message is updated is carried out. Due to the fact that echo reply message buffering is updated before expiration, the problems that due to the fact that the echo reply message buffering is not updated because of the expiration and a large number of domain name queries have a request to get to a back-end DNS to carry out recurrent iteration queries, the DNS system has a low-speed response to the request of the domain name queries and response delay is larger are effectively avoided.

An effective bus arbitration unit is described in which it is possible to reduce, as much as possible, the waiting time until a bus master obtain bus ownership and improve the rate of operating the bus while improving the throughput of data transfer. A bus master issues a size signal (for example, signal “CDSZ”) indicative of the size of data to be read or written. A state machine 155 grants bus ownership to the bus master for the bus cycles corresponding to the size signal in order to enable the bus master to successively read or write data. Arbitration is performed once for every series of bus cycles corresponding to the size requested by the bus master. Since the size signal is issued by the bus master as a size signal indicative of the necessary and sufficient size for data transmission, the state machine 155 can set an optimal number of bus cycles.
