Method and device for converging and shunting IP datagram, equipment and medium

Abstract

The embodiment of the invention discloses a method and a device for converging and shunting an IP datagram, equipment and a medium. The method comprises the following steps: receiving a GTP-U message;acquiring an unpacking protocol which is preset in a protocol stack and corresponds to the GTP-U message, and analyzing the GTP-U message by adopting the unpacking protocol to obtain a data packet; and acquiring a preset data packet shunting rule, and performing convergence and shunting on the data packet according to the shunting rule. According to the technical scheme provided by the embodimentof the invention, the GTP-U message can be filtered and shunted, and the chip can correctly analyze the GTP-U data message according to the customization demand, so that the inner layer IP filteringfunction of the GTP-U message is realized, and the GTP-U message meets the current network demand.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of computer networks, and in particular to a method, device, device and medium for converging and distributing IP datagrams. Background technique [0002] The converging and splitting device copies, aggregates, and filters the datagrams received from the network, converts the POS data into 10G LAN data through protocol conversion, and performs load balancing output according to a specific algorithm, and ensures the same session at the same time. All data packets, or all data packets of the same IP user are output from the same interface. Based on network security requirements, it is necessary to place different datagrams in different data analyzers for data analysis in a targeted manner. The convergence and splitter is the first choice for the job, and the received messages are matched according to the matching rules set in advance. , filter the datagram according to different rules a...

Problems solved by technology

[0003] The current converging and splitting device is limited by the fact that the chip can only resolve the existing protocols in the chip. Based on the aggregation and splitting requirements of the live network, when the converging and splitting device receives a GTP-U message and needs to filter and forward it to the designated port according to the rules of the inner IP protocol or discard actions, because the GTP-U protocol type is not an existing protocol on the chip, so the GTP-U protocol message cannot be correctly parsed, so the filtering and splitting cannot be realized according to the inner layer IP data of GTP-U
