Problems solved by technology

With the explosion of 5G ultra-large bandwidth applications and the growth of video applications, the forwarding capability of UPF equipment is required to be dozens of times higher. Therefore, the CPU and software acceleration solutions cannot meet future needs.
[0003] The existing UPF equipment is based on the DPDK pure software acceleration solution of the x86 platform to realize the forwarding and billing processing of GTP messages. If the capacity needs to be increased, the configuration or number of CPUs must be increased, resulting in a sharp increase in the cost of the UPF equipment.

Abstract

The invention discloses a UPF system based on the cooperation of switches and UPF equipment and a control method thereof, which are applied in the field of communication equipment, including UPF equipment and switches. The UPF equipment is used for receiving GTP-C messages, and according to the GTP-C The message establishes a GTP session and determines the forwarding strategy of the GTP session, and issues the forwarding strategy; the switch management CPU is used to forward the information between the UPF device and the switching chip; the switching chip is used to obtain the GTP-C from the input port message and GTP-U message, forward the GTP-C message to the UPF device through the switch management CPU, and receive the forwarding policy issued by the UPF device from the switch management CPU, according to the The forwarding policy described above forwards GTP-U packets to the output port and collects accounting statistics. The invention can complete the processing of large-scale GTP message without greatly increasing the hardware cost.

Description

technical field [0001] The invention relates to communication equipment, in particular to a UPF system based on cooperation of switches and UPF equipment and a control method thereof. Background technique [0002] The current UPF device is based on the X86 CPU to complete the forwarding and billing processing of GTP data packets. Considering the performance of a single CPU, some UPF devices are completed by a multi-core CPU, or even a combination of multiple CPUs. For the DPDK pure software acceleration solution for the x86 platform, the maximum capacity is only 25Gbps. With the explosion of 5G ultra-large bandwidth applications and the growth of video applications, the forwarding capability of UPF equipment is required to be dozens of times higher. Therefore, the CPU and software acceleration solutions cannot meet future needs. [0003] The existing UPF equipment is based on the DPDK pure software acceleration solution of the x86 platform to realize the forwarding and bill...
