Systems and methods for multilayer peering
A software defined network, in accordance with some examples of the disclosure, may be used to optimizing traffic across a multi-layer inter-exchange for applications like automated private peering by incorporating packet switching along with OTN and/or optical switching into a converged system. Participants in private peering may have ports into the multi-layer inter-exchange, some to the L2 fabric which supports multi-tenant peering and some to the L1 or L0 fabric for higher-performance private peering.
1. A method for establishing a connection between first and second networks, the first and second networks being autonomous from one another; the method comprising:
receiving a request for a connection from the first network to the second network separate from the first network;
coupling a first device of the first network to a second device of the second network remote from the first device;
sending first network routing information from the first device to the second device;
sending second network routing information from the second device to the first device;
sending first data from the first device to the second device using the second network routing information in a first format, the first format being layer 2 format;
converting the first data from the first format to a second format, the second format being a layer 0 or a layer 1 format; and
sending second data from the second device to the first device using the first network routing information in a second format.
2. The method of claim 1 , further comprising:
receiving the first data at the second device in the second format.
3. The method of claim 1 , further comprising:
converting the second data from the second format to the first format; and
receiving the second data at the first device in the first format.
4. The method of claim 1 , further comprising:
converting the first data from the first format to the second format;
transmitting the first data in the second format;
converting the first data from the second format to the first format; and
receiving the first data at the second device in the first format.
5. A method for establishing a peering connection between first and second networks, the first and second networks being autonomous from one another; the method comprising:
connecting the first network to a first device;
connecting the second network to the first device;
receiving first network routing information at the first device;
receiving second network routing information at the first device;
receiving first data from the first network at the first device, the first data being in a layer 2 format;
converting the first data from the layer 2 format to a layer 1 format or a layer 0 format; and
sending the first data to the second network in the layer 1 format or the layer 0 format using the second network routing information.
6. The method of claim 5 , wherein the first device is one of an Ethernet switch or a first router and a second router, the first router configured to route the first data using the first network routing information and the second router configured to route the first data using the second network routing information.
