    摘要: A server causes a user device configured as a test agent to implement a testing plan for testing a network configuration regarding zero-rating. By causing the test agent to implement the testing plan, the server causes the test agent to send one or more requests to one or more respective predetermined IP addresses. The server receives data indicating results of the one or more requests. The server further uses the data to identify whether the network configuration is potentially misconfigured regarding zero-rating. In response to identifying that the network configuration is potentially misconfigured regarding zero-rating, the server sends a notification of the potential misconfiguration to a network operator.

    摘要: A method of operating a control entity of a communication network comprises storing (101) configuration data for a node (10) of the communication network. The control entity determines (102) a congestion level of the communication network. The control entity sets (103) a duration of a heartbeat signal waiting period based on the determined congestion. The duration of the heartbeat signal waiting period increases with increased congestion. The control entity determines (104) if synchronisation of configuration data is required with the node based on whether a heartbeat signal, or a predetermined number of heartbeat signals, is received from the node within the heartbeat signal waiting period. The control entity may determine (102) a congestion level of the communication network based on delay times of configuration notifications received from a node (10), or a plurality of nodes (10), in the network.

    摘要: A network device in a network is provided that is configured to implement a process for modifying a timestamp in a packet that is a timing protocol packet. The timing protocol packet is encapsulated by a user data protocol (UDP) datagram, where the modified timestamp is written into the packet, but does not require a checksum of the UDP datagram to be changed. The process includes receiving a packet including a first timestamp over the network, receiving the first timestamp from the packet and a second timestamp to be written to the packet, and determining a third timestamp that is a modification of the second timestamp to be written to the packet, the third timestamp having least significant bits modified from the second timestamp such that the checksum of the UDP datagram is unchanged. The process writes the third timestamp into the packet and transmits the UDP datagram to the network.

    摘要: The subject matter described herein relates to method, systems, and computer readable media for detecting physical link intrusions. A method for detecting physical link intrusions includes monitoring a link delay signature associated with a physical link based on one-way link delay measurements obtained using at least one network tap. The method also includes determining whether a change in the link delay signature has met or exceeded a threshold value. The method further includes in response to determining that the change in the link delay signature has met or exceeded the threshold value, determining that a physical link intrusion has occurred.

    摘要: Monitoring of a life cycle of a connection of a network client device to a network via monitoring time synchronization traffic flowing between one or more network client devices and a time server in a network is provided. A system for monitoring a life cycle of a connection of a network client device to a network includes a security device operable to identify a true identity of the one or more network client devices, identify a network client device's connections to and disconnections from the network, determine which network client devices have been associated with a particular internet protocol (IP) address, and generate an output of connection and disconnection information associated with a network client device. In some examples, the security device is operable to detect anomalies and malicious patterns in the network.
