Method and system for a secure bi-directional line switched ring
View Patent ↗A method or system including implementing one or more indicators to specify traffic ordering associated with an optical networking protocol and ordering traffic according to the one or more indicators.
1. A method, comprising:
implementing, on an optical network, one or more indicators to specify traffic ordering associated with an optical networking protocol;
ordering traffic, on an optical network, according to the one or more indicators;
wherein the ordering comprises sending data on a first set of non-contiguous timeslots;
sending data over a second set of non-contiguous timeslots in response to a protection event in a portion of the optical network associated with the first set of non-contiguous timeslots;
sending pseudo random data on the first set of non-contiguous time slots in response to the protection event; and
configuring receiving nodes to ignore the pseudo random data.
2. The method of claim 1 wherein the one or more indicators are implemented in a synchronous optical networking bi-directional line switched ring based network utilizing unused overhead bits.
3. The method of claim 2 wherein the traffic ordering comprises:
configuring a first set of multiplexed time slots to transmit data; and
configuring a second set of multiplexed time slots as reserved time slots.
4. The method of claim 3 wherein the first set of multiplexed time slots comprise one or more synchronous transport signal level 1 channels to transmit data around a synchronous optical networking ring; and
the second set of multiplexed time slots comprise one or more synchronous transport signal level 1 channels that are reserved to transmit data around the synchronous optical networking ring in response to a protection switch.
5. The method of claim 3 wherein the traffic ordering is fixed.
6. The method of claim 3 where the traffic ordering varies.
7. The method of claim 2 further comprising:
implementing one or more encryption indicators to specify encryption associated with payload data; and
encrypting the payload data.
8. The method of claim 7 wherein the encryption varies in response to a protection switch.
9. A system comprising:
a security protocol module that implements one or more security protocols for managing traffic ordering in an optical network;
wherein the one or more security protocols are implemented within an optical networking protocol and the traffic ordering is altered from a contiguous ordering scheme associated with the optical networking protocol to a scheme in which data is transmitted on a first set of non-contiguous timeslots;
the security protocol module being further configured to:
send data over a second set of non-contiguous timeslots in response to a protection event in a portion of the optical network associated with the first set of non-contiguous timeslots;
send pseudo random data on the first set of non-contiguous time slots in response to a protection event; and
configure receiving nodes to ignore the pseudo random data.
10. The system of claim 9 wherein the security module implements the one or more security protocols in a synchronous optical networking bi-directional line switched ring based network utilizing unused overhead bits.
11. The system of claim 9 wherein the traffic ordering configures synchronous transport signal level 1 channels in a first and a second direction around a synchronous optical networking ring based on the one or more security protocols.
12. The system of claim 9 wherein the traffic ordering is fixed.
13. The system of claim 9 wherein the traffic ordering varies.
14. The system of claim 9 wherein the security module encrypts payload data.
15. The system of claim 9 , further comprising:
sending pseudo random data through the portion of the network associated with a protection switch; and
configuring one or more receiving nodes to ignore the pseudo random data.
