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 cooperation of a switch and a UPF device and a control method thereof, which are applied to the field of communication devices. The UPF system comprises the UPF device and the switch, wherein the UPF device is used for receiving a GTPC message, establishing a GTP session according to the GTPC message, determining a forwarding strategy of the GTP session, and issuing the forwarding strategy; the switch management CPU is used for forwarding information between the UPF equipment and the switch chip; and the switch chip is used for acquiring the GTPC message and the GTPU message from the input port, forwarding the GTPC message to the UPF equipment through the switch management CPU, receiving the forwarding strategy issued by the UPF equipment fromthe switch management CPU, forwarding the GTPU message to the output port according to the forwarding strategy, and performing charging statistics. According to the invention, large-scale GTP messageprocessing can be completed under the condition that the hardware cost is not greatly increased.

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...
