Abstract: Some embodiments provide a method of identifying packet latency in a software defined datacenter (SDDC) that includes a network and multiple host computers executing multiple machines. At a first host computer, the method identifies and stores (i) multiple time values associated with several packet processing operations performed on a particular packet sent by a first machine executing on the first host computer, and (ii) a time value associated with packet transmission through the SDDC network from the first host computer to a second host computer that is a destination of the particular packet. The method provides the stored time values to a set of one or more controllers to process to identify multiple latencies experienced by multiple packets processed in the SDDC.

Abstract: The disclosed systems, methods and computer readable media relate to managing Non-Volatile Memory Express (NVMe) over Transmission Control Protocol (TCP) (NVMeOTCP) connections between a smart network interface card (smartNIC) and a block storage data plane (BSDP) of a cloud computing environment. A software agent (“agent”) executing at the smartNIC may manage a number of network paths (active and, in some cases, passive network paths). The agent may monitor the network traffic (e.g., input/output operations (IOPS)) through the paths (e.g., using established NVMeOTCP connections corresponding to the paths). If a condition is met relating to a performance threshold associated with the monitored paths, the agent may increase or decrease the number established NVMeOTCP connections to match real time network conditions.

Abstract: Local Congestion Mitigation re-routes traffic around a congested network segment without regard for end point destinations of the re-routed traffic.

These methods therefore remain relatively efficient as a network grows in size and network routes within the network become increasingly complex.

Abstract: This application provides a packet forwarding method and a related apparatus. The method includes: determining whether a flow to which a packet belongs meets a large flow condition; and if the flow to which the packet belongs meets the large flow condition and a flowlet routing table does not include a flowlet entry corresponding to the flow, creating the corresponding flowlet entry in the flowlet routing table, and forwarding the packet based on the created flowlet entry. In the foregoing technical solution, a corresponding flowlet entry may be created only for a large flow, to perform flowlet-based load balancing on the large flow. This can reduce an entry resource used for flowlet-based load balancing, improve balance of multi-path load sharing, and effectively improve a traffic sharing effect of load balancing.

Abstract: A method and system for latency-driven multi-media redirection. Through multi-media redirection, multi-media content from one or more multi-media sources may be re-routed to an endpoint to be decoded and/or rendered thereon. This redirection of multi-media content diverges from the traditional approach of directing the multi-media content from the multi-media source(s) to an information technology environment to be decoded and/or rendered prior to delivery of the decoded/rendered multi-media content to an endpoint. Current criteria for employing multi-media redirection are many, however, fail to consider network latency as a potentially crucial factor in the decision process for enabling or disabling multi-media redirection. Accordingly, the disclosed method and system propose the automated enablement or disablement of multi-media redirection based on network latency analyses.

Abstract: The present invention proposes a new method for solving the problem of fault tolerance. This new approach obtains all secondary routes assigned to each possible connection (user). The secondary routes replace the main routes when these are affected by at least one fault, which keeps the users connected as long as, for each connection, there is at least one route with operative links for reaching the destination nodes thereof. This new approach solves the general case of an arbitrary set of simultaneous link failures. The method also assesses the number of wavelengths for each link of the network, so that the probability of any connection request from a determined user c being blocked is less than a predefined threshold ?c, despite the possible occurrence of the fault scenario.
