1.3.2 Component Object Model Plus (COM+) Event System Protocol

The COM+ Event System Protocol provides a way to manage events and their respective subscriptions on a remote machine. The protocol is exposed as a set of DCOM [MS-DCOM] interfaces.

Using the protocol a publisher can publish, update, or delete an event on a remote machine. Similarly, a subscriber can use the protocol to create a subscription for an event on a remote machine. It can also modify, query, or delete subscriptions for an event on the remote machine.

A subscriber can specify that it wishes to receive a specific type of event or a collection of events. This is defined by specifying filtering criteria.
