Subject: Using GPU to do packet forwarding
Date: Tue, 24 Aug 2010 15:15:07 -0700 [thread overview]
Message-ID: <20100824151507.5c13bd69@s6510> (raw)
Interesting paper:
http://www.ndsl.kaist.edu/~kyoungsoo/papers/packetshader.pdf
One section of general consideration is the expense of the current
skb scheme. At 10G, they measure 60% of the CPU is used doing skb
alloc/free; see paper for the alternative of using a huge
packet buffer. Also, they managed to shrink skb to 8 bytes!
