Abstract
An optical transceiver for use in network device in a packet network is provided. The network device may not be capable of providing a ring topology without use of the apparatus. The network device is configured to support at least two optical interfaces and an electrical interface, and coupled to an optical link. The optical transceiver includes a memory, a processor coupled to the memory, and a scheduler coupled to the processor. The scheduler of the optical transceiver is configured to perform as an information base for forwarding and transferring of packets and to use an optical link as a packet buffer.
Claims11
An optical transceiver for use in a network device in a packet network comprising a ring topology, the network device being configured to support at least two optical interfaces and an electrical interface and to couple to an optical link, the optical transceiver comprising:
- a memory;
- a processor coupled to the memory;
- and
- a scheduler coupled to the processor,
- wherein the scheduler is configured to:
- perform as an information base for forwarding and transferring packets;
- and
- use the optical link as a packet buffer, and
- wherein a length of the packet buffer is determined based on one or more measurements of a propagation delay on the optical link divided by an operating frequency of the packet network having a ring topology.
A network arrangement for digital communications in a packet network, comprising:
- an access point (AP) device;
- one or more network elements each provisioned with a single network port and coupled to an optical link for optical communications;
- and
- one or more smart optical transceivers each including at least two optical interfaces and an electrical interface,
- wherein, when the one or more smart optical transceivers are plugged into the one or more network elements and the access point device, the network arrangement forms a ring topology,
- wherein the one or more smart optical transceivers include a scheduler configured to perform as an information base for forwarding and transferring packets and to use an optical link as a packet buffer, and
- wherein a length of the packet buffer is determined based on a propagation delay measured on the optical link divided by an operating frequency of the packet network having the ring topology.
