  • Patent number: 11398958
    Abstract: In one embodiment, a networking device reroutes traffic in a network from a first path to a second path, based on a prediction that the first path will not satisfy a service level agreement associated with the traffic. The networking device enters a fast monitoring state during which the networking device performs fast probing of the first path and of the second path onto which the traffic was rerouted. The networking device makes, based on the fast probing, a determination as to whether the first path would have violated the service level agreement and whether the second path violates the service level agreement. The networking device enacts a routing decision for the traffic by applying a routing policy to the determination.

  • Patent number: 11388043
    Abstract: A system that implements a data storage service may store data on behalf of storage service clients. The system may maintain data in multiple replicas of various partitions that are stored on respective computing nodes in the system. The system may employ a single master failover protocol, usable when a replica attempts to become the master replica for a replica group of which it is a member. Attempting to become the master replica may include acquiring a lock associated with the replica group, and gathering state information from the other replicas in the group. The state information may indicate whether another replica supports the attempt (in which case it is included in a failover quorum) or stores more recent data or metadata than the replica attempting to become the master (in which case synchronization may be required). If the failover quorum includes enough replicas, the replica may become the master.

  • Patent number: 11044630
    Abstract: This application discloses a method and an apparatus for adjusting a data sending rate. In the method, when determining that a return time of feedback information of a first data packet has timed out, a terminal reduces a data sending rate of a connection to which the first data packet belongs from a first value to a second value. Then the terminal detects return times of feedback information of a plurality of subsequent data packets after the first data packet and determines a cause of the timeout of the feedback information of the first data packet. The terminal further increases a data sending rate from a current third value to a fourth value when determining that the timeout is caused by a packet loss on a wireless link in a communications link.

  • Patent number: 10999132
    Abstract: Technologies are provided for identifying problems with network monitoring agents. For example, a network monitoring agent that is experiencing network packet loss can be examined to determine if it is degraded. For example, metrics can be obtained that are associated with the network monitoring agent. The obtained metrics can then be evaluated against thresholds. For example, if a high confidence metric is outside of a threshold for the high confidence metric, then a determination can be made that the network monitoring agent is degraded. As another example, if two low confidence metrics are outside of respective thresholds, then a determination can be made that the network monitoring agent is degraded. If a network monitoring agent is degraded, then its monitoring data can be discarded.
