Choices, Choices, Choices Identity at the Transport Level Can we provide a mechanism to allow identity / locator independence at the session level? An application opens a session with a generated session identity token The identity token is dynamically associated with locator pairs Changes in locators do not change the session token Application of the layering approach Allow applications to assume a framework of identity association Perform identity / locator association at a lower level of the protocol stack Use opportunistic identity values that have a limited context and role of supporting session integrity Support legacy applications by providing a consistent API |
