Abstract

A first fabric abstraction layer couples to a data link layer and a physical layer of a network fabric device. The network fabric device is connected to other network elements within a network via at least one network connection, such as a fiber optic connection. A second fabric abstraction layer couples to the data link layer and an application of the network device. The second fabric abstraction layer provides an application programming interface (API) to the application. The API allows the application to generate configuration instructions for configuring the at least one network connection. Upon receiving the configuration instructions generated by the application, the second abstraction layer sends the configuration instructions to the first abstraction layer via the data link layer. The first abstraction layer then configures the at least one network connection to transmit data according to the configuration instructions.

the aggregation layer device comprises at least one of a bridge, a switch, a router, and an Ethernet card; and

the upper layer device comprises at least one of a web server, an e-mail server, and a voice over IP server.

3. The network device of claim 1, wherein the network connection comprises multiple physical channels.

4. The network device of claim 3, wherein the multiple physical channels comprises a wavelength dimension and a time dimension.

5. The network device of claim 4, wherein the multiple physical channels comprises at least 88 physical channels at each time slice, wherein each of the at least 88 channels has a distinct optical wavelength.
