Intelligent address registration for optical user-network interface
View Patent ↗A technique for address registration and resolution is disclosed. In one embodiment, the technique is realized by an address registration and resolution service that is applicable to in-band in-fiber, out-of-band in-fiber and out-of-band out-of-fiber O-UNI signaling configurations. Through this address registration and resolution scheme, an optical service subscriber or optical access service provider can register various client-layer addresses (i.e., establish an association between the client addresses and the optical network points of attachment for the network intelligence.) An intelligent optical routing protocol will propagate this information all over the network and use this information to locate a corresponding optical client device and the optical network point of attachment. The optical network signaling can then perform the network internal signaling for on-demand optical service provisioning.
1. A method for intelligent address registration within an optical network, the method comprising the step of:
sending a registration request from a client-side optical user-network interface agent to a network-side optical user-network interface agent, wherein the registration request includes a client layer address to be registered and an identity of an addressable entity;
checking the registration request with the network-side optical user-network agent and creating an association by retrieving an optical network administered address and creating a mapping between the client layer address and optical network administered address; and
forwarding the association to an optical network intelligent routing protocol for distribution over the network.
2. The method of claim 1 , further comprising performing the step of resolution upon inquiry from a remote peer.
3. The method of claim 1 , wherein the identity of the addressable entity includes at least a client ID and a client port ID.
4. The method of claim 3 , wherein the identity of the addressable entity further includes a channel ID.
5. The method of claim 4 , wherein the identity of the addressable entity further includes a sub-channel ID.
6. The method of claim 1 , further comprising the step of creating a mapping between multiple client layer addresses and an optical network administered address.
7. The method of claim 1 , further comprising the step of creating a mapping between multiple client layer addresses and multiple optical network administered addresses.
8. The method of claim 7 , further comprising the step of maintaining scalability by creating a virtual optical network administered address representative of multiple optical network administered addresses.
9. An apparatus for performing address registration and resolution for an optical network, the optical network comprising at least an optical network element and a client device, the apparatus comprising:
a client-side optical user-network interface agent having tools for formulating and forwarding an address request containing a client layer address associated with the client device and an identity of an addressable entity associated with the optical network element;
a network-side optical user-network interface agent to receive the request from the client-side optical user-network interface agent, formulating an address association based on the request, and forwarding the address association, wherein the address association is formulated by retrieving an optical network administered address and creating a mapping between the client layer address and optical network administered address;
an optical network intelligent routing protocol capable of receiving the address association formulated by the network-side optical user-network interface agent and propagating the address association.
10. The apparatus of claim 9 , further comprising tools for removing a client device from the network.
11. The apparatus of claim 9 , further comprising apparatus to perform address resolution upon inquiry_for the optical network administered address associated to the client layer address.
12. The apparatus of claim 9 , wherein the identity of the addressable entity includes at least a client ID and a client port ID.
13. The apparatus of claim 12 , wherein the identity of the addressable entity further includes a channel ID.
14. The apparatus of claim 13 , wherein the identity of the addressable entity further includes a sub-channel ID.
15. The apparatus of claim 9 , wherein the network-side optical user-network interface agent additionally comprises tools to create a mapping between multiple client layer addresses and an optical network administered address.
16. The apparatus of claim 9 , wherein the network-side optical user-network interface agent further comprising tools to create a mapping between multiple client layer addresses and multiple optical network administered addresses.
17. The apparatus of claim 16 , wherein the network-side optical user-network interface agent further comprises tools to maintain scalability by creating a virtual optical network administered address representative of multiple optical network administered addresses.
