Abstract

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.

Claims (26)

1. A method for reconfiguration of a circuit-switched ring network to a packet-switched ring network comprising, 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:

provisioning a second circuit-switched path indirectly coupling the pair via one or more intermediate network elements;

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.

4. A method according to claim 1 , further comprising adding packet switch-based transmission media between the pair of network elements.

5. A method according to claim 4 , wherein the packet switch-based transmission media comprises one of Ethernet cable or optical fiber.

6. A method according to claim 1 , wherein the circuit-switched ring network is a bidirectional line switched ring (BLSR) network.

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.

10. The non-transitory computer-readable medium according to claim 9 , wherein the logic is further configured to remove circuit switch-based transmission media coupled between the pair of network elements.

11. The non-transitory computer-readable medium according to claim 10 , wherein the circuit switch-based transmission media comprises optical fiber.

12. The non-transitory computer-readable medium according to claim 9 , wherein the logic is further configured to add packet switch-based transmission media between the pair of network elements.

13. The non-transitory computer-readable medium according to claim 12 , wherein the packet switch-based transmission media comprises one of Ethernet cable or optical fiber.

14. The non-transitory computer-readable medium according to claim 9 , wherein the circuit-switched ring network is a bidirectional line switched ring (BLSR) network.

15. The non-transitory computer-readable medium according to claim 9 , wherein the packet-switched ring network is a G.8032 network.

16. The non-transitory computer-readable medium according to Claim 9 , wherein the logic is further configured to provision the one or more intermediate network elements as pass-through nodes for traffic between the pair of network elements.
