Table item management method and device

Abstract

The invention discloses a table item management method and equipment. The method includes: a network device determines to apply for a QoS service table item, and the QoS service table item corresponds to service entity information and service parameter information; Record the service entity information in the service entity, and record the address of the service entity entry in the QoS service entry; the network device judges whether the service parameter information is recorded in the service parameter entry; Record the address of the business parameter table item that records the business parameter information into the business entity table item; if not, record the business parameter information in the business parameter table item, and record the business parameter information of the business parameter information The address of the parameter entry is recorded in the service entity entry. In the present invention, FPGA resources can be saved, and the utilization rate of FPGA resources can be improved.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a method and device for managing entries. Background technique [0002] The combination of FPGA (Field Programmable Gate Array, field programmable array) and CPU (Central Processing Unit, central processing unit), and relying on FPGA to realize message forwarding is the development direction of high-performance network equipment; CPU is responsible for complex configuration management and protocol processing , table entry creation and other work; FPGA will perform business processing and forwarding on the message according to the table entry issued by the CPU. [0003] It should be noted that in order to be consistent with the CPU business processing effect, FPGA needs to perform targeted processing for each CPU business; for example, in CPU business processing, CAR (Committed Access Rate, agreed access rate) business has an interface-based CAR service, CAR servic...

Problems solved by technology

[0005] However, since there are many QoS configuration services and they belong to different modules ( figure 1 The QoS service 1 configuration in the middle belongs to the module of the flow table and the corresponding module of the interface table), so that the FPGA needs to perform repeated processing for each QoS service belonging to different modules, so that the design flexibility of the FPGA is not high, and the resource utilization of the FPGA rate is not high

Furthermore, as the number of flows increases, the FPGA's requirements for various entries also increase. When the entry resources are insufficient, in order to ensure the basic forwarding function, it is necessary to limit the scale of other business entries, so that subsequent flows cannot be realized. Other business, affecting the availability of system functions
