A coherent, intelligent, packet-switched memory fabric enables predictive, cache-coherent access across distributed compute, accelerator, and memory resources using a Memory-Fabric Transaction Layer Protocol (MF-TLP). MF-TLP defines routable packet formats for read, write, vectorized, atomic, reduction, collective, and predictive-prefetch transactions executed by memory-centric network interface controllers (MC-NICs). Each MC-NIC performs packet parsing, address translation, coherence management, and near-memory arithmetic or tensor operations while coordinating with MF-TLP-aware switches providing hierarchical directory control, multi-path routing, and in-network aggregation. Vectorized and multimodal packets encode multiple addresses or tensor offsets to reduce scatter / gather overhead, and programmable caching and quality-of-service modules manage tiered memory and tenant fairness. MF-TLP supports extension headers for predictive prefetch, collective coordination, and tenant governance, operating across hierarchical leaf-spine topologies using Ultra-Ethernet Transport, InfiniBand, or CXL fabrics. The system delivers scalable, low-latency, memory-centric orchestration for large-language-model training, multimodal AI, and data-intensive analytics.

Solutions are disclosed that enable capacity-aware local repair of tunnels in packet switched wide area networks (WANs). Traffic engineering agents on the routers are programmed to create the tunnels and include sets of primary and alternate tunnels sharing the same source and destination. A tunnel source router is provided a traffic split for allocating incoming traffic to its primary and alternate tunnels for when the primary tunnel is operating at or near full capacity operation, and another traffic split that shifts at least some traffic from the primary tunnel to the alternate tunnel, when the primary tunnel's capacity drops below a threshold. A tunnel may lose capacity for commonly-occurring reasons, such as a disturbance to cabling and faults in optical transceivers. Traffic engineering agents along the tunnel report capacity to the tunnel source router, permitting the network to respond to capacity changes more rapidly than waiting for network tunnel reconfiguration.

The present disclosure refers to methods and systems to reduce delays in VoWI-FI handover and packet switching registration.

This invention relates to a method for autonomously obtaining the Owner node of an Ethernet ring network based on an improved ERPS protocol, belonging to the field of industrial internet technology. By adding a new field to the reserved fields of the ERPS protocol and adding corresponding opcodes, an improved ERPS protocol is obtained. This enables an Ethernet ring network composed of switch nodes supporting the improved ERPS protocol to not only be compatible with and support existing ERPS protocol communication, but also to have the ability to autonomously obtain the Owner node. In an Ethernet ring network composed of switch nodes supporting the improved ERPS protocol, each switch node first traverses the Ethernet ring network to obtain the total number of switch nodes, then applies a hash ring to obtain the corresponding group number for each switch node, then selects the master switch node within the same group, and finally selects the global master switch node as the Owner node from all group master switch nodes. This solves the problem in existing technologies where the Owner node of an Ethernet ring network cannot autonomously recover after a failure, resulting in poor robustness and fault tolerance of the network platform.

Packet switching operations in network devices are managed based on detection of excess rate traffic flows. A network device receives data units, determines the traffic flow to which the data units belong, and updates flow tracking information for the flow. The network device uses the tracking information to determine when the rate at which the network device is receiving data belonging to the flow exceeds an excess rate threshold and is therefore an excess rate flow. The network device can enable one or more excess rate policies for excess rate traffic flows. Such policies can include any number of features affecting how the device handles data units belonging to the flow, such as excess rate notification, differential discard, differential congestion notification, and reprioritization. Memory and other resource optimizations for such flow tracking and management are also described.

Devices, systems, methods, and processes for switch triggered faster go-back-N recovery are described herein. Typically, Go-back-N recovery is triggered in response to: a receiver missing a packet and receiving a next packet in a data transmission sequence, or a sender timing out and identifying a missing acknowledgement for a dropped packet. Such scheme suffers potential latency issues, especially when the dropped packet is the last packet or corresponds to a single packet message. Thus, instead of relying on the sender to timeout and identify missing acknowledgements or on the receiver to receive the next packet, a switch executes a packet mirroring and trimming scheme on the dropped packet and generates a trimmed out-of-order packet of the same reliable connection flow. The trimmed out-of-order packet causes the receiver to transmit a negative acknowledgement to the sender, thus triggering faster go-back-N recovery and causing the sender to retransmit the dropped packet.

The present invention discloses a low-latency educational video monitoring method and system, which specifically relates to the field of network monitoring technology. By counting the network paths that can be used for live broadcasts, the jitter variation coefficient value, delay-bandwidth product deviation rate, and packet switching stability index of each network path are collected, and a transmission quality index is established through a normalized formula.
