Description
Technical Field
The present disclosure relates to the field of communication information processing, and in particular, to a method and an apparatus for issuing a routing table entry of a deep service switching gateway, an electronic device, and a computer-readable medium.
Background
In order to simplify management and networking of a deep service switching gateway (DPX) environment, reduce maintenance difficulty and operation and maintenance cost and improve usability, a DPX equipment main control board is responsible for managing complete machine configuration, routing table item management and part of complex service processing. The routing table entry is generated by the master control through a dynamic routing protocol or user static configuration, the generated routing table entry is issued to each service board card through an internal channel by the master control, if the rate of issuing the routing table entry by the master control exceeds the performance of the internal channel, the issued information packet is lost, the routing table entry on the service board is incorrect, and whether the routing table entry of the master control is consistent with the routing table entry of the service board needs to be checked.
In the prior art, whether the routing table entries of the master control and the service board are consistent or not can be checked through manual participation, and when the routing table entries of the master control and the service board are inconsistent, the routing table entries of the master control are manually modified, so that the master control re-issues the routing table entries with problems to the service board, and the effect of consistency of the routing table entries of the master control and the service board is achieved. This method requires manual work to participate in the inspection, and cannot guarantee that the routing table entry inconsistent with the main control board and the service board can be inspected in real time. Moreover, if the master controller uses a routing table entry generated by the dynamic routing protocol, the dynamic routing protocol is modified manually, which may cause the routing protocol to oscillate.
In the prior art, the rate of issuing the routing table entry of the service board by the master control can be reduced, so that the rate cannot exceed the performance of the internal channel, and the condition of packet loss is avoided. The speed reduction in this way can cause the slow down process of the routing table entry, and influence the effective time of the routing table entry of the service board. And because each service board shares the internal channel, the speed of the channel can be influenced by the number of the service boards and the performance of the service boards, and the speed of issuing the routing table items by the master control is difficult to control to be a proper value so as to achieve the flexible application scheme suitable for different service board performances and different service board numbers.
Therefore, a new method, an apparatus, an electronic device, and a computer-readable medium for issuing a routing table entry of a deep service switching gateway are needed.
The above information disclosed in this background section is only for enhancement of understanding of the background of the application and therefore it may contain information that does not constitute prior art that is already known to a person of ordinary skill in the art.
