Joel, Agree that "I2RS Clients locate I2RS agents by many means". For each method, there must be a coordinator (or system) to facilitate the association. My main point is let the "restart status" being sent to this "coordinator", instead depending on the I2RS agent's non-volatile DB. It is possible during the time that this I2RS agent is down, the client is reassigned to a different agent.

For example, an I2RS agent may start by using local means to find its local router. It can then use I2RS mechanisms to get the topology. Based on that, and the service it wants to provide, it can then select which I2RS agents to register with and what events to register for. But that is only one example. It may be that some other entity (a PCE for example) provides the needed topology information. Or any number of other deployment models. The I2RS Agent failure notification mechanism ought not be dependent upon the I2RS client deployment and management strategy.
