Description

Technical field:

[0001] The present invention relates to a router system, in particular to a SOHO router system based on embedded Linux. Background technique:

[0002] With the rapid development of communication technology and network technology, a large number of network devices are connected to the network, and the number of Internet users is increasing exponentially. Studies have shown that the IPv4 address space will be exhausted before 2011, so IPv4 address resources are very scarce. SOHO routers use private network IP addresses to effectively alleviate the current crisis of IP address shortage, and provide efficient and cheap shared Internet access solutions for small LANs such as companies and families. The current SOHO router design adopts the ARM7TDMI+Clinux design architecture, the ARM7 core microprocessor operating frequency is about 50M, while the Ethernet control chip operating frequency is generally 100M, the processor speed is difficult to meet the requiremen...
