EOBI Optimization for Partition 4 on 12 December 2022

Eurex is planning to deploy an optimization to EOBI for partition 4 on 12 December 2022.  The optimization will lead to an improved latency profile for the market data distribution via EOBI. There is a residual risk that the optimization will, in rare cases, lead  to packets being sent out of sequence.

Please note that out of sequence messages are part of the protocol which can already happen now and which are described in the EOBI manual in section 4.17. In the unlikely event that out of sequence messages are visible on partition 4 on 12 December, Eurex plans to revert the optimization for the next day.
