Automatic flow management
Packet-switching operations in a network device are managed based on the detection of excessive-rate traffic flows. A network device receives a data unit, determines the traffic flow to which the data unit belongs, and updates flow tracking information for that flow.

The network device may enable one or more excessive-rate policies on an excessive-rate traffic flow. Such a policy may include any number of features that affect how the device handles data units belonging to the flow, such as excessive-rate notification, differentiated discard, differentiated congestion notification, and reprioritization.

Multi-stage prefix matching enhancements
Approaches, techniques, and mechanisms are disclosed for maintaining efficient representations of prefix tables for utilization by network switches and other devices. In an embodiment, the performance of a network device is greatly enhanced using a working representation of a prefix table that includes multiple stages of prefix entries. Higher-stage prefixes are stored in slotted pools. Mapping logic, such as a hash function, determines the slots in which a given higher-stage prefix may be stored. When trying to find a longest-matching higher-stage prefix for an input key, only the slots that map to that input key need be read. Higher-stage prefixes may further point to arrays of lower-stage prefixes. Hence, once a longest-matching higher-stage prefix is found for an input key, the longest prefix match in the table may be found simply by comparing the input key to lower-stage prefixes in the array that the longest-matching higher-stage prefix points to. |

Ghost routing
Ghost routing is a network verification technique that uses a portion of a production network itself to verify the impact of potential network changes. Ghost routing logically partitions the production network into a main network and a ghost network. The main network handles live traffic while the ghost network handles traffic generated for diagnostic purposes. The ghost network may have a network topology identical to the production network and may use the same hardware and software as the production network. An operator may implement a network configuration change on the ghost network and then use verification tools to verify that the network configuration change on the ghost network does not result in bugs. Verifying on the ghost network may not affect the main network. If the network operator verifies the network configuration change on the ghost network, the network operator may implement the network configuration change on the main network. |

Two dimensional (2D) transition metal dichalcogenide (TMD) materials and alloys as catalysts for cathode in lithium sulfur (Li-S) batteries
Two-dimensional (2D) material-based metal or alloy catalysts synthesized on carbon materials (e.g., carbon nanotubes) prevent polysulfide shuttling and overcome technical challenges for developing practical lithium-sulfur (Li—S) batteries. Soluble lithium polysulfides (LiPSs) tend to shuttle during battery cycling and corrode a Li anode, leading to eventual performance fading in the Li—S battery. This shuttle effect can be reduced by accelerating the conversion of the dissolved polysulfides to the insoluble LiPSs and back to the sulfur. A 2D material-based alloy or 2D material synthesized on carbon materials can suppress polysulfide shuttling by catalyzing polysulfide reactions. 2D material-based alloys with 2H (semiconducting)—1T (metallic) mixed phase exhibit synergistic effects of accelerated electron transfer and catalytic performance as confirmed by the lower charge-transfer resistance of carbon nanotube (CNT)—S cathode and the high binding energy of LiPSs to the catalyst. |
