Abstract: Disclosed are systems, methods, and non-transitory computer-readable storage media for monitoring application health via correctable errors. The method includes identifying, by a network device, a network packet associated with an application running on a node, detecting, by the network device, a correctable error associated with the network packet, and encoding, by the network device, a tag within the network packet, the tag including one or more fields for storing data associated with the correctable error.

Abstract: The subject disclosure relates to systems and methods for improving multicast traffic flows in a computer network. In some aspects, a method of the technology includes steps for receiving multicast traffic statistics from each of a plurality of switches in a computer network, aggregating the multicast traffic statistics into a time-series database, and identifying a low-performing multicast flow based on the time-series database. In some aspects, the method can include steps for automatically reconfiguring the computer network to improve the low-performing multicast flow. Systems and machine readable media are also provided.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable storage media for monitoring application health via correctable errors. The method includes identifying, by a network device, a network packet associated with an application and detecting an error associated with the network packet. In response to detecting the error, the network device increments a counter associated with the application, determines an application score based at least in part on the counter, and telemeters the application score to a controller. The controller can generate a graphical interface based at least in part on the application score and a timestamp associated with the application score, wherein the graphical interface depicts a trend in correctable errors experienced by the application over a network.

Abstract: Techniques for identifying network congestion and adapting network performance to relieve the network congestion are described. As described, a network element such as a switch reports network congestion indicators such as link level control frames to a network controller. The network controller uses the network congestion indicators reported from the network elements to identify congestion points, data traffic, and data flows experiencing congestion at a network level. The network controller then determines optimized control parameters for the network in order to reduce or alleviate the congestion at the congestion points.

Abstract: A first node of a packet switched network transmits at least one flow of protocol data units of a network to at least one output context of one of a plurality of second nodes of the network. The first node includes X virtual output queues (VOQs). The first node receives, from at least one of the second nodes, at least one fair rate record. Each fair rate record corresponds to a particular second node output context and describes a recommended rate of flow to the particular output context. The first node allocates up to X of the VOQs among flows corresponding to i) currently allocated VOQs, and ii) the flows corresponding to the received fair rate records. The first node operates each allocated VOQ according to the corresponding recommended rate of flow until a deallocation condition obtains for the each allocated VOQ.
