Networking technology has improved constantly over time, and it is now regularly possible to get bandwidths of 10 Gbps and often considerably more. Is this purely “free speed,” or does it simply create new application bottlenecks and scaling challenges? This session begins by discussing how to enable Java for high-speed communications, such as SDP, and then moves on to sharing some hard-learned real-world experiences showing how improving network speeds often results in unexpected surprises. Come hear about the amazing promise of RDMA and the sometimes sobering reality of high-speed networks. Take away a clear view of the issues, and hear some practical advice on achieving great performance when moving Java applications to high-speed networks.
