[RP] And endpoint is an application, not an IP. So, an endpoint can be in many PIDs.

But those just move an endpoint between PIDs. That's fine. At any given time, the endpoint is only in one PID. But I disagree with #2. The endpoints in a multi-homed network may have two different routes, but they are in one PID, not two PIDs. Here's how I look at it: if I want to send a packet to 10.0.0.1, I just tell the network to send the packet. I do *not* tell the network the route or which gateway to use. [RP] The interface and source selection address determines to a great extend the path the packet will take through a network. Both are possible today and with IPv6 will be much more pervasive. That's the network's job. And the network does its best to hide that from users. Similarly, an ALTO client just wants the cost from endpoint A to B. The client doesn't want to guess the best route. That's the ALTO server's job. - Wendy From: "Reinaldo Penno (repenno)" <[email protected]<mailto:[email protected]>> Date: Mon, October 28, 2013 10:37 To: Wendy Roome <[email protected]<mailto:[email protected]>>, "Y.

Yes, an endpoint can move from one PID to another in case of Mobile IP Yes, and endpoint can be found in multiple PIDs if it is in a multi-homed network, I.e., a network where the gateway is connected to multiple networks. Yes, and endpoint can move from one PID to another if the Gateway is down since a host interface can be withdraw and the endpoint will move. Thanks, Reinaldo
