The upgrade will focus on setting up faster backup systems for security information processors (SIP), networks that send information about quotes and trades made on exchanges, the paper reported.

The discussions held among thirteen exchanges to upgrade the system stem in part from an SEC order issued in September to review the SIPs after the outage.
