A multicast message replication method and apparatus are provided. The method includes: stepstoring a received message in a message cache module, and an inter-port replication module acquiring a cache address of the message, inter-port replication information of the message, and inner-port replication information of the message, replicating the cache address according to the inter-port replication information, and transmitting the replicated cache address and the corresponding inner-port replication information to a port queue module to be stored; stepa port scheduling module scheduling the cache address of the port queue module, and under the scheduling by the port scheduling module, the port queue module outputting a cache address for which message replication needs to be performed according to the stored corresponding inner-port replication information; stepthe message cache module reading a corresponding message according to the cache address output by the port queue module and outputting.

Multicast message replication method and device

A method and an apparatus for calculating packet arrival time interval are provided by the present invention. In the above-mentioned method, when the current packet arrives, system current time Tis read from a timer, and the arrival time T, recorded in an external RAM, of previous packet of the flow to which the current packet belongs is read (), wherein the timer implements a cycle timing with a period of preset time period T, the preset time period Tis larger than or equal to the time for filling the maximum depth of the token bucket of the flow at the minimum token injection rate; a current flag bit, recorded in an internal RAM, of the flow to which the current packet belongs is read (), wherein the current flag bit is used for indicating the number of cycles of the timer between the system current time Tand the arrival time Tof previous packet; and the arrival time interval of the present packet is calculated according to the system current time T, the arrival time Tof previous packet and the current flag bit (). Application of the present invention can reduce the consumption of the internal RAM and improve the operability for realizing by the hardware chips.
