This is the network model and where our COPS extension fits.

To support traffic engineering, PDP's and PEP's exchange tunnel and filter information via COPS. Two key parameters are

Whenever something goes wrong with the LSP's, the router needs to notify the problem to the PDP immediately. When a PEP receives filter Requests, it setup packet filters to "pipe" user data into the tunnel(s).
