Abstract: A monitoring device/module monitors a plurality of nodes in a data center network, and determines one or more latency distributions of response times for messages exchanged between pairs of nodes of the plurality of nodes. The network monitoring device determines a network topology, including one or more communication links interconnecting nodes of the plurality of nodes, consistent with the one or more latency distributions. The network monitoring device also determines a representative response time for each communication link based on the one or more latency distributions, and compares a current response time a message exchanged between one pair of nodes to the representative response time for the communication link interconnecting the one pair of nodes. The network monitoring device identifies a network anomaly when the current response time deviates from the representative response time for the communication link interconnecting the one pair of nodes by a threshold amount.

Abstract: The disclosed technology relates to a process for general-purpose ring buffer handling in a network controller. Specifically, general purpose ring buffers are used in software queue on both the host domain and the network controller to carry out user-defined protocols. The protocols define the relationship of the ring buffers in the host domain and the network controller domain (e.g. how data is moved and processed). The protocols minimize interruptions to the network controller. Furthermore, the implementation of ring buffers in the network controller domain also provides additional resources to the host domain for carrying out the user-defined protocols.
