Creating bi-directional co-shared sessions and switching bi-directional co-shared sessions

摘要

Methods and systems for fast switching between bi-directional co-shared sessions having different network paths over a resource reservation network. Embodiment of one method includes: creating a bi-directional parent session (S_p) between first and second session partners, creating a bi-directional derivative session (S_d) between the first session partner and a third session partner, and reassigning a predetermined amount of co-shared network resources (PA-CSNR) assigned to the S_p using the following steps: (i) sending a first message to request the second session partner to stop using the PA-CSNR, (ii) sending a second message to register whether the PA-CSNR are assigned to the S_d, and (iii) sending a third message to allow the third session partner to utilize at least some of the PA-CSNR for the S_d.
