Subject: Re: [Wireshark-users] Ideas for 10G capture platform?
I'm also curious. Although I'm assuming we're in a similar state to the capture situation with 1Gig Ethernet 8 or so years, where:
- Few NICs could actually receive and process packets at line speed.
- A surprisingly large number of NICs refused to enter passive mode, and some had problems allocating buffers properly for jumbo frame handling.
- There were few, if any, inline capture solutions that could capture bidirectionally, though fiber taps were possible. Copper taps were not yet available.
- For extended captures (more than a few seconds), disk speed is a tremendous bottleneck and nowhere near linespeed+full packet capture is possible, even with modestly-expensive RAID solutions.
- Host BUS speeds actually became a problem, either becoming a quick bottleneck when others (NIC+disk) were loosened, or exacerbating them.
...But I have done no testing of my own this time around.
