Abstract: Techniques are disclosed for exchanging anonymized information between autonomous systems. In one example, a method comprises accessing an eigenvalue, wherein the eigenvalue is based on topology data associated with the first autonomous system; encoding the eigenvalue into a message; and transmitting, by a network element located in the first autonomous system, the message to an external edge router located in the second autonomous system. A further method can comprise receiving, by a network component located in a first autonomous system, a message, wherein the message comprises an eigenvalue and the message is received from an external network element located in a second autonomous system; accessing another other eigenvalue, the another eigenvalue corresponding to an autonomous system different from the first autonomous system; analyzing the another eigenvalue and the eigenvalue; and executing, by the network element, an action based on the analyzing.

Abstract: Embodiments provide techniques for transmitting data packets across a deterministic Ethernet network. Embodiments receive, at a first device in the deterministic Ethernet network, a deterministic binary schedule specifying timing information for transmitting data fragments relating to a plurality of data flows. Data packets to transmit to a destination device within the deterministic Ethernet network are received at the first device. Embodiments include fragmenting each of the data packets into two or more fragments and encoding at least one of the two or more fragments for each of the data packets with a respective sparse graph code. The encoded fragments are transmitted to the destination device, across multiple paths through the deterministic Ethernet network, according to timing information specified in the deterministic binary schedule.

Abstract: In one embodiment, a method includes receiving packets in a flow at a network device in a deterministic network, wherein at least one of the packets is transmitted from a source out of sync due to collision with another flow at the source, analyzing at the network device, the flow to reconstruct a period of the flow, and processing at the network device, the packets according to the period to synchronize the processing of the packets at the network device with the source and remove jitter from the flow. An apparatus and logic are also disclosed herein.
