Systems and methods for reconfiguration of a circuit switched ring to a packet switched ring
In accordance with embodiments of the present disclosure, a method for reconfiguration of a circuit-switched ring network to a packet-switched ring network is provided. The method may include, for each adjacent pair of network elements in a network bridging traffic between the pair of network elements via a second path other than a first circuit switched-based path directly coupling the pair. The method may also include provisioning packet switched-based network interfaces on each of the pair of network elements. The method may additionally include establishing a packet switched-based path directly between the packet switched-based network interfaces. The method may further include switching traffic from the first path to the packet switched-based path.

switching the traffic from the first circuit switched-based path to the second circuit-switched path;
provisioning packet switched-based network interfaces on each of the pair of network elements;
establishing a packet switched-based path directly coupling the packet switched-based network interfaces; and
switching traffic from the second circuit-switched path to the packet switched-based path.
2. A method according to claim 1 , further comprising removing circuit switch-based transmission media coupled between the pair of network elements.
3. A method according to claim 2 , wherein the circuit switch-based transmission media comprises optical fiber.

7. A method according to claim 1 , wherein the packet-switched ring network is a G.8032 network.
8. A method according to Claim 1 , further comprising provisioning the one or more intermediate network elements as pass-through nodes for traffic between the pair of network elements.
9. A non-transitory computer-readable medium comprising logic for reconfiguring a circuit-switched ring network to a packet-switched ring network, the logic configured to, for each adjacent pair of network elements in a network having a first circuit-switch path directly coupling the pair and communicating traffic between the pair:
provision a second circuit-switched path indirectly coupling the pair via one or more intermediate network elements;
switch the traffic from the first circuit switched-based path to the second circuit-switched path;
provision packet switched-based network interfaces on each of the pair of network elements;
establish a packet switched-based path directly coupling the packet switched-based network interfaces; and
switch traffic from the second circuit-switched path to the packet switched-based path.
