Method and network for connecting a first end device to a network. One method includes the following steps: supporting, by a common data link layer, both Ethernet protocol and time sensitive network protocol; utilizing the Ethernet protocol for discovering, by the first end device, at least one other end device that is connected to the network; and utilizing the time sensitive network protocol for sending time sensitive data by the first end device to the at least one other end device over the network.

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) between first and second session partners, creating a bi-directional derivative session (S) 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 Susing 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, and (iii) sending a third message to allow the third session partner to utilize at least some of the PA-CSNR for the S.

Methods and systems for a resource reservation network that supports bi-directional co-shared sessions. A session creation module (SCM) creates a bi-directional parent session (S), between first and second session partners, by: allocating co-shared network resources over a first network hop, and allocating network resources over a second network hop. The SCM further creates a bi-directional derivative session (S) between the first session partner and a third session partner, by: allocating network resources to the Sover a third network hop, and not allocating specifically for the Sall the network resources required for the Sover the first network hop.

A session creation module (SCM) creates a bi-directional parent session (S), between first and second session partners, by: allocating co-shared network resources over a first network hop, and allocating network resources over a second network hop.

Fast switching between co-shared sessions

Methods and systems for creating bi-directional co-shared sessions and switching between bi-directional co-shared sessions. Embodiment of one method includes the following steps: Sending a first message over a bi-directional parent session network path (P) to indicate allocation of network resources along the P, including co-shared network resources. Creating the parent session (S) by sending a first session creation message. Sending a second message over a bi-directional derivative session network path (P) to indicate allocation of non-co-shared network resources along the P. And creating the Sby sending a second session creation message.

Creating bi-directional co-shared sessions over a resource reservation network

Methods and systems for resource reservation networks configured to maintain low latency and latency variation of co-shared sessions. A session creation module (SCM) creates a bi-directional parent session (S), between first and second session partners, by: allocating co-shared network resources over a first network hop, and allocating network resources over a second network hop; wherein the network resources allocated to the Sguarantee a maximum end-to-end latency variation (e2eLV) below 100 usec. The SCM further calculates a maximum e2eLV of a potential bi-directional derivative session (S) between the first session partner and a third session partner; wherein the potential Sutilizes network resources over a third network hop and the co-shared network resources over the first network hop. And the SCM creates the Sresponsive to determining that the maximum e2eLV of the Sbeing below 100 usec.
