Just the memory moves are insane.Īn alternative is to use a DSP for software based routing which generally can improve performance substantially in these cases as they tend to contain a separate "Device" which they call an enhanced DMA controller, but instead is simply a device which is programmable to move memory using DMA. ![]() Even using modern high end ARM CPUs, performing routing within software at bitrates over 60MBps is a challenge. Wireless routers will be an issue in high bandwidth environments for a time to come since wireless routers typically use low end ARM processors and perform software based routing. I have personally considered in the past using KickStarter to design a SOHO Layer-3 switch with IPv6 and NAT. ![]() ![]() Many ISPs are offering 100MBps+ (in civilized countries) knowing there are factors involved such as the fact that the consumers will either never use the allocated bandwidth and there will be even less who can find suitable hardware to handle the connection. This is an issue which is more likely to effect Slashdotters than the average daily user. ![]()
