L1 Edge Timestamping Layer
CFE utilizes Layer 1 replication devices between all customer latency equalized cross connects and L3 customer access switches to enable timestamping and packet capture at the network edge. Information collected by these devices will be used by Cboe for internal analysis and troubleshooting purposes. These L1 timestamping devices will add approximately 20ns of additional one-way latency. Clock synchronization for packet timestamping uses Cboe's internal White Rabbit time distribution network.
