While international law enforcement officers from Latvia, Portugal and other jurisdictions will not engage in frontline duties, the PSNI has been deployed to assist Irish police forces during the two-day event.
The operation involves approximately 15,000 Gardaí rotating through twelve-hour shifts over Thursday and Friday.
More than five hundred public order officers are scheduled to be on duty each day alongside a contingent of one hundred advanced escort-trained motorcyclists.
Additional security includes over two hundred motorcycle escorts and more than two hundred members of trained search teams supported by the Garda Water and Dog unit together with the Irish Defence Forces.
Authorities have indicated that water cannon may be utilised if required to manage public order situations.

The heightened security measures will commence incrementally starting Tuesday 10 November and continue through Wednesday.
