Abstract

The invention discloses a satellite-borne IP switching device supporting an IPv4 and IPv6 dual-stack routing protocol and an SRv6 protocol, and belongs to the technical field of satellite communication. The system comprises a business analysis processing unit, an SID table query configuration management unit, an FIB table query configuration management unit, an SRv6 encapsulation unit, an SRv6 de-encapsulation unit, a WAN port network card receiving unit, an LAN port network card receiving unit, a WAN port network card sending unit and an LAN port network card sending unit which are realized based on an FPGA. And four functions of public network exchange processing, private network exchange processing, public network-private network conversion and private network-public network conversion can be realized. The method and the system support random exchange of multiple interface types, multiple protocol types, multiple LAN ports and multiple WAN ports, are flexible and configurable, and have strong expansibility.
