Description
Technical Field
The present disclosure relates to the field of communication information processing, and in particular, to a method, an apparatus, an electronic device, and a computer readable medium for issuing a routing table entry of a deep service switching gateway.
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 items are generated by the main control through dynamic routing protocol or static configuration of users, the generated routing table items are issued to each service board by the main control through an internal channel, if the rate of the main control issuing routing table items exceeds the performance of the internal channel, the issued information packet loss occurs, the routing table items on the service board are incorrect, and whether the routing table items of the main control are consistent with the routing table items of the service board is required to be checked.
In the prior art, whether the routing table entries of the main control and the service board are consistent or not can be checked through manual participation, and when the routing table entries of the main control and the service board are inconsistent, the routing table entries of the main control are manually modified, so that the main control can issue the routing table entries with problems to the service board again, and the effect of consistent routing table entries of the main control and the service board is achieved. The method needs to be manually checked, and can not ensure that the inconsistent routing table items of the main control and the service board can be checked in real time. Moreover, if the dynamic routing protocol used by the master control generates a routing table entry, the dynamic routing protocol is manually modified, which can cause the routing protocol to oscillate.
In the prior art, the rate of the main control issuing service board routing table entry can be reduced, so that the rate cannot exceed the performance of an internal channel, and the situation of packet loss is avoided. The slow down of this way can result in slow down of the routing table entry, affecting the service board routing table entry validation time. And because each service board shares an 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 the master control for issuing the routing table item is difficult to control the routing table item to be at a proper value so as to achieve a flexible application scheme suitable for different service boards and different service boards.
Therefore, there is a need for a new routing table entry issuing method, apparatus, electronic device, and computer readable medium for a deep traffic switching gateway.
The above information disclosed in the background section is only for enhancement of understanding of the background of the application and therefore it may contain information that does not form the prior art that is already known to a person of ordinary skill in the art.
