Abstract: A method for routing in a quantum network is provided. The method may include receiving parameters including a fidelity with coherence decay time and an entanglement generation rate for each quantum node in a mesh quantum network by a controller, the controller being configured to communicate with each quantum node of a plurality of quantum nodes in the mesh quantum network. Each quantum node includes a quantum memory and a processor. The method may also include analyzing the fidelity with coherence decay time and the entanglement generation rate to yield a determination of a path fidelity with a path coherence decay time and a path entanglement generation rate between at least one pair of quantum nodes. The method may further include, based on the determination, selecting a quantum communication path from a source node to a destination node.

Abstract: Techniques are provided for signal translation in a hybrid network environment. In one example, a first provider edge node obtains a connection status indication from a first one of a second provider edge node via a packet switched network or a third provider edge node via a time-division multiplexing transport network. The first provider edge node translates the connection status indication between a packet switched network format and a time-division multiplexing transport network format. The first provider edge node provides the connection status indication to a second one of the second provider edge node via the packet switched network or the third provider edge node via the time-division multiplexing transport network.

Abstract: Techniques are presented herein for load-balancing a sequence of packets over multiple network paths on a per-packet basis. In one example, a first network node assigns sequence numbers to a sequence of packets and load-balances the sequence of packets on a per-packet basis over multiple network paths of a network to a second network node. The second network node buffers received packets that are received over the multiple network paths of the network from the first network node and re-orders the received packets according to sequence numbers of the received packets.

Abstract: In one example, an indication of a time during which a network communication obtained from a first network node was processed by the first network node, and an indication of a propagation delay from a second network node to the first network node, are obtained. A time during which the network communication was processed by the second network node is determined. A propagation delay from the first network node to the second network node is calculated based on the time during which the network communication was processed by the first network node and the time during which the network communication was processed by the second network node. A difference between the propagation delay from the first network node to the second network node, and the propagation delay from the second network node to the first network node, is determined and compensated is made for that difference.

Abstract: In one embodiment, an apparatus includes n electrical communication channels, m optical communication media interfaces, and a plurality of muxes. The plurality of muxes are configured to receive an information stream. The information stream is carried over the n electrical communication channels and the m optical communication media interfaces. The plurality of muxes are further configured to transform the information stream from v virtual lanes. Each virtual lane includes a plurality of data blocks from the information stream and an alignment block, wherein v is a positive integer multiple of the least common multiple of m and n, v is greater than n, and n is equal to m.

Abstract: A method, system, and computer-readable medium for a network interface with adjustable rate are disclosed. For example, one method involves receiving a request to activate a virtual lane of an interface, where the request is received by a first node. The interface is configured to facilitate data communication between the first node and a second nod, and the interface includes a plurality of virtual lanes that include at least one active virtual lane, and at least one inactive virtual lane. The method also involves, in response to receiving the request, negotiating with the second node to select an additional virtual lane from the at least one inactive virtual lane. The method involves activating the additional virtual lane. After the activating, the first node and the second node are configured to use the active virtual lane(s) and the additional virtual lane for data communication.
