The Nexus 3548 with Algo Boost was announced last week and received a lot of positive buzz around this game changing innovation. To follow up on Berna Devrim’s Introduction Blog, I am introducing a multipart series that goes into more specifics by Cisco experts. As part 1 of the series, I recently had the opportunity to have a chat with Will Ochandarena about the latency enhancements. Will is a Senior Product Manager in the Server Access and Virtualization Business Unit. In this role, he is responsible for the Nexus 3548 switch, and Cisco’s low latency switching strategy.
GD: The Cisco Nexus 3548 switch with Algo Boost was announced on September 19th and received a lot of positive attention. Can you elaborate a little more on the latency that this switch can achieve? How does this benefit our financial customers?
<WO>: The custom switching ASIC in the Nexus 3548, codenamed Monticello, sets a new bar for switching latency. Our engineers worked tirelessly to eliminate unnecessary nanoseconds from the forwarding path, tweaking it down to as low as 190 nanoseconds (ns). Best of all, this latency is achieved even when we are doing full layer-2 and layer-3 switching, with features such as Network Address Translation (NAT) enabled. We actually went as far as to offer a few different switching modes, each with different latency and forwarding characteristics, in order to give our customers the most flexibility in their deployments.
In terms of the impact on our end customers, we consistently hear from companies in the financial community that switch latency has a direct impact on the profitability of their business. Trading firms – as well as the exchanges and other participants – gain significant business advantage if the supporting infrastructure enables them to acquire data and execute trades nanoseconds faster than the competition.
