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.

It is disclosed a method for exchanging packets between a first and second nodes of a packet-switched network. Each packet comprises two fields PLG and PLR settable to an idle value or measurement value. The first node transmits to the second node first packets having their PLG set to measurement value (generation). Upon reception of each first packet, the second node transmits back to the first node a second packet having its PLG set to measurement value. Upon reception of each second packet, the first node transmits to the second node a third packet having its PLR set to measurement value (reflection). A packet loss measurement may be calculated as a difference between number of first packets and number of third packets. Since two fields PLG, PLR are used, the first node may start a new generation step before end of reflection. This results in high measurement throughput (100% theoretically).

A method is disclosed for enabling a performance measurement on a multipoint packet flow carrying live traffic through a packet switched communication network. Each packet comprises a marking bit, which before its transmission is set to either a first value indicating that the packet is to be subjected to a sample performance measurement, or a second value indicating that the packet is not to be subjected to a sample performance measurement. A measurement point placed on the path of the packet reads the value of its marking bit and: if it is set to the first value, it generates a sample performance parameter relating to the packet; otherwise, it updates a cumulative performance parameter relating to the multipoint packet flow as a whole. A sample measurement based on the sample performance parameter and / or a multipoint performance measurement based on the cumulative performance parameter may then be performed.

In-network Optical Inference (IOI) provides low-latency machine learning inference by leveraging programmable switches and optical matrix multiplication. IOI uses a transceiver module, called a Neuro Transceiver, with an optical processor to perform linear operations, such as matrix multiplication, in the optical domain. IOI's transceiver modules can be plugged into programmable packet switches, which are programmed to perform non-linear activations in the electronic domain and to respond to inference queries. Processing inference queries at the programmable packet switches inside the network, without sending them to cloud or edge inference servers, significantly reduces end-to-end inference latency experienced by users.
