The Cboe One Feed is offered from Cboe’s primary datacenter (Equinix’s NY5) and secondary datacenter (CenturyLink’s CH4), along with Cboe’s Points-of-Presence (PoP) in Equinix’s NY4 and CH1.

Recipients will have the ability to take the Cboe One Feed via either TCP/IP or Multicast, and either delivery method can be used as a standalone product. Additionally, the TCP/IP feed can be used to augment the Multicast feed for recovery and start up purposes as both delivery methods use the same binary protocol and sequencing to allow for easy arbitration.

Additionally, the Feed can be received in multiple locations worldwide through Cboe Global Cloud with various secure connectivity options. Cboe Global Cloud is available in regions globally including the U.S., Europe, and Asia-Pacific.

Multicast Gap Recovery

Firms that elect to receive the Cboe One Feed via Multicast may optionally request a Cboe One Gap Request Proxy (GRP) session to request retransmission of a missed message(s). Gap requests will be made via TCP/IP to the GRP server, and the requested messages will be retransmitted on designated gap response Multicast Addresses. Firms receiving the Cboe One Feed via Multicast are also advised to take the same version (Summary or Premium) of the Cboe One Feed via TCP/IP for the purpose of replaying messages out of range of the GRP server or obtaining a refresh of the current state of the Cboe books intraday.
