A method of utilizing the same hardware network interface card (NIC) in a gateway of a datacenter to communicate datacenter tenant packet traffic and packet traffic for a set of applications that execute in the user space of the gateway and utilize a network stack in the kernel space of the gateway. The method sends and receives packets for the datacenter tenant packet traffic through a packet datapath in the user space. The method sends incoming packets from the NIC to the set of applications through the datapath in the user space, a user-kernel transport driver connecting the kernel network stack to the datapath in the user space, and the kernel network stack. The method receives outgoing packets at the NIC from the set of applications through the kernel network stack, the user-kernel transport driver, and the data path in the user space.

Provided is a method and apparatus for searching for a Maintenance End Point (MEP), and a storage medium. The method includes that: a chip of the MEP parses an obtained packet; the chip of the MEP determines whether a field of the parsed packet matches a field in a combination of a port and a Virtual Local Area Network (VLAN); and in a case where the field of the parsed packet matches the field in the combination of the port and the VLAN, the chip of the MEP determines that the MEP is found successfully.

The technology of this application relates to a method and apparatus. A first service packet of a target service flow received by a packet receiving node includes in-situ flow detection information, and the in-situ flow detection information includes a detection flag and a sequence number of the first service packet. When determining, based on the detection flag, that out-of-order detection needs to be performed, the packet receiving node may perform the out-of-order detection based on the sequence number of the first service packet and a sequence number of a second service packet.

There is provided a communication apparatus that enables acquisition of data to be sent after a Secure Shell (SSH) connection between a wireless unit and a baseband unit is established. A communication apparatus (10) according to the present disclosure includes a communication unit (11) that establishes a first Secure Shell (SSH) connection with a wireless apparatus (20) that performs wireless communication with a communication terminal (40), and establishes a second SSH connection with a control apparatus (30) that performs a baseband process related to a signal used in the wireless communication, and a data recording unit (12) that records data of a management plane received from the wireless apparatus (20) through the first SSH connection or the data of the management plane received from the control apparatus (30) through the second SSH connection.

This disclosure describes techniques for configuring and managing scalable global private networks associated with a service provider. Different input mechanisms, such as an API, a UI, or a CLI may be utilized to configure, and manage a global private network that spans across the cloud in different geographic locations and connects to different stand-alone networks. The user may proactively use the input mechanisms to configure and query different network resources to reactively configure settings for reacting to one or more events. The input mechanisms may also be utilized to define the network resources to be modeled within the global private network as well as connections within the global network. A user may configure events/metrics to be monitored, tasks/workflows to be performed, and the like. In some configurations, a network management service (NMS) may perform health monitoring and reachability monitoring to identify possible issues in the global network.

A disclosure of the present specification provides a method for operating an access and mobility management function (AMF) node for selecting a session management function (SMF) node. The method may comprise the steps of receiving a first message including application function (AF) request information from an AF node; selecting or reselecting an SMF on the basis of the AF request information; and transmitting a second message including the AF request information to the selected or reselected SMF.

This application provides a method and an apparatus for configuring minimization of drive-tests MDT. The method for configuring MDT includes: A terminal device receives first MDT measurement configuration information and first indication information from a first network device. The terminal device learns, based on the first indication information, whether a type of first MDT configured by the first network device for the terminal device is signaling based MDT or management based MDT. Further, after establishing a connection to a second network device, the terminal device sends second indication information to the second network device, and reports the type of the first MDT that has been configured for the terminal device. The management based MDT overwrites signaling based MDT previously configured by the first network device for the terminal device can be avoided, thereby increasing a possibility that the management based MDT does not overwrite the configured signaling based MDT.

An operational component according to the present embodiment operates autonomously by transmitting and receiving a message as a part of a maintenance and management system that maintains and manages a service. The operational component includes a message transmission and reception unit that transmits and receives a message to and from another operational component; a firing rule storage unit that holds a firing rule including a trigger for executing an action and the action to be executed; and an action execution unit that executes the action, in the firing rule, to be executed in response to the received message as the trigger. The action execution unit includes one or more action modules that execute an action; an action module execution unit that causes one of the action modules corresponding to the action in the firing rule to execute the action; and a message transmission instruction unit that transmits a message including a result of execution from the action modules.

Some embodiments provide a method of migrating a first software defined (SD) network managed by a first network manager to a second SD network managed by a second network manager. The method of some embodiments is performed by a third network manager that provides an interface that allows a set of users to specify and review logical network components, which the first and second network managers can then respectively deploy in the first and second SD networks. The third network manager in some embodiments identifies for a migration manager a first group of two or more logical network components that the third network manager previously specified for the first network manager to deploy in the first SD network. The migration manager then uses this information to correctly convert the first group of logical network components to a second group of two or more logical components in an appropriate manner that will allow the third network manager to manage the second group of logical network components that is implemented in the second SD network.
