Abstract
In one embodiment, method of wrapping photonic packets includes receiving, by a node, a first packet and receiving, by the node, a second packet. The method also includes concatenating the first packet and the second packet to produce a concatenated frame, where concatenating the first packet and the second packet includes removing an inter-packet-gap (IPG) between the first packet and the second packet and converting the concatenated frame to a photonic frame, where the concatenated frame is an electrical frame.
Claims24
A method of wrapping photonic packets, the method comprising:
- receiving, by a node, a first packet;
- receiving, by the node, a second packet;
- concatenating the first packet and the second packet to produce a concatenated frame, wherein concatenating the first packet and the second packet comprises removing an inter-packet-gap (IPG) between the first packet and the second packet, and wherein concatenating the first packet and the second packet further comprises
- writing the first packet to a buffer,
- writing the second packet to the buffer, and
- reading out the buffer to produce the concatenated frame;
- and
- converting the concatenated frame to a photonic frame, wherein the concatenated frame is an electrical frame.
A method of wrapping photonic packets, the method comprising:
- receiving, by a node, a first packet;
- receiving, by the node, a second packet;
- determining a first destination group of the first packet;
- determining a second destination group of the second packet;
- determining whether the first destination group equals the second destination group;
- concatenating the first packet and the second packet to produce a concatenated frame, wherein concatenating the first packet and the second packet comprises removing an inter-packet-gap (IPG) between the first packet and the second packet, and wherein concatenating the first packet and the second packet is performed when the first destination group equals the second destination group;
- and
- converting the concatenated frame to a photonic frame, wherein the concatenated frame is an electrical frame.
A method of wrapping photonic packets, the method comprising:
- receiving, by a node, a first packet;
- receiving, by the node, a second packet;
- concatenating the first packet and the second packet to produce a concatenated frame, wherein concatenating the first packet and the second packet comprises removing an inter-packet-gap (IPG) between the first packet and the second packet;
- converting the concatenated frame to a photonic frame, wherein the concatenated frame is an electrical frame;
- adding a label to the photonic frame to produce a first wrapped photonic frame;
- determining a destination address of the first wrapped photonic frame;
- setting up a connection in a photonic switch during a gap time between the first wrapped photonic frame and a second wrapped photonic frame;
- and
- switching the first wrapped photonic frame after setting up the connection in the photonic switch.
