Corvil

Corvil's appliances capture the traffic of a trading infrastructure without loss, decode the market-data and order protocols inside it, and turn the packets into the measurements the business runs on: feed latency and gaps, tick-to-trade times, fill ratios, and the network symptoms behind them, retransmissions, congestion and round-trip times, at one-second resolution. The pre-sales engagement is the conversation that follows: where the capture points sit, which protocols the estate speaks, what a millisecond costs the customer and who on the floor reads the dashboards. It is the one corner of this record where a network is measured in the currency of the application that runs on it.

The Corvil Certified Administrator credential, earned in 2020, was the condition for running those conversations with the vendor's support behind them; it lapsed in 2022, when the week belonged to the classroom, and the record keeps it with its dates. The company itself had just changed hands: founded in Dublin in 2000 out of Trinity College research, with the exchanges and banks of New York, London and Tokyo as its customers, Corvil was acquired in 2019 by Pico, the New York financial-markets infrastructure provider, and continues as Pico's Corvil Analytics. Its story is on the industry page.
