Abstract

The invention discloses a method and system for fast synchronization of table items. The method for fast synchronization of table items includes: first step, the user sends the table item to the CPU of the main control board; second step, the CPU of the main control board passes through the The out-of-band channel between the boards sends the entry to the service board CPU; the third step, the main control board CPU sends the table item to the service board NP processor through the inter-board in-band channel; the fourth step, the service board CPU passes the inter-board The out-of-band channel asynchronously receives entries to the local database of the service board, and at the same time, the NP processor of the service board synchronously receives the entries through the off-board channel. The present invention introduces the mode of asynchronously receiving entries by the CPU of the service board, so that the CPU of the service board releases the current receiving and processing task in a shorter time to perform the next receiving and processing. In addition, after receiving the table items, they only need to be synchronized to the database of the board, and do not need to be sent to the NP processor of the board through the PCIe channel on the board, which simplifies the processing process and releases more CPU resources.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for fast synchronization of entries. Background technique [0002] In the existing communication equipment, especially in the frame type communication equipment, in order to synchronously deliver the table items to the network processor (Network Processor, NP for short) of each service board, it is often necessary for the central processor of the main control board to (Central Processing Unit, referred to as CPU) is responsible for sending entries, and the service board CPU is responsible for receiving entries and sending them to the NP processor of the board. The entire synchronous transmission process of entries uses an out-of-band channel between boards. Take a chassis-type communication device as an example, refer to figure 1 , the communication device has a main control board and a service board, the main control board CPU is connected to the serv...
