Various embodiments provide a resource allocation method and an apparatus. In those embodiments, a terminal device obtains a first parameter indicating a maximum service data volume to be provided by an access network device for a first service in a first time length; and determines, based on the maximum service data volume, a resource of a media access control protocol data unit MAC PDU, the resource being occupied by buffered data of the first service. In those embodiments, the terminal device determines, based on the maximum service data volume of the first service, the resource of the MAC PDU. Compared with a conventional method, the maximum service data volume of the first service is considered. This helps improve reasonableness of allocating the resource of the MAC PDU to the data of the first service.

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.

A method and apparatus for transmitting a service flow based on a flexible Ethernet, where a bandwidth resource corresponding to a bundling group (BG) of a flexible Ethernet is divided into M timeslots, service data of a service flow is encapsulated in N timeslots in the M timeslots, and the method includes: when a first PHY in the BG fails, determining, based on a preconfigured first timeslot configuration table (TCT), a target timeslot (TTS) in the N timeslots that is mapped to the first PHY; searching the M timeslots for an idle timeslot (ITS) based on the first TCT; adjusting the first TCT when a quantity of ITSs is greater than or equal to a quantity of TTSs, so that all the N timeslots are mapped to PHYs other than the first PHY; and transmitting the service flow by using the mapped PHYs of the bundling group.

The present disclosure relates to systems and methods for transport capacity scheduling. The systems and methods may determine a target region, wherein a plurality of service requests that satisfy a preset condition initiate from the target region. The systems and methods may determine a non-busy region based on information of the target region. The non-busy region may include one or more available service providers that are free to accept a service request. The systems and methods may transmit, via a network, a scheduling instruction associated with the plurality of service requests to a user terminal associated with at least one of the one or more available service providers in the non-busy region. The scheduling instruction may include information inquiring whether the at least one of the one or more available service providers in the non-busy region agrees to go to the target region.

The present application discloses a method and apparatus for controlling a database connection. A specific embodiment of the method comprises: receiving an access request for a database sent by a terminal; determining whether a database connection pool comprises an idle database connection for the database; reusing the idle database connection to connect the terminal with the database if the database connection pool comprises the idle database connection for the database; and establishing a new database connection, in order to connect the terminal with the database by utilizing the new database connection if the database connection pool comprises no idle database connections. This embodiment effectively utilizes fewer database connections to support database access requests.

Embodiments relate to xMR sensors, in particular AMR and/or TMR angle sensors with an angle range of 360 degrees. In embodiments, AMR angle sensors with a range of 360 degrees combine conventional, highly accurate AMR angle structures with structures in which an AMR layer is continuously magnetically biased by an exchange bias coupling effect. The equivalent bias field is lower than the external rotating magnetic field and is applied continuously to separate sensor structures. Thus, in contrast with conventional solutions, no temporary, auxiliary magnetic field need be generated, and embodiments are suitable for magnetic fields up to about 100 mT or more. Additional embodiments relate to combined TMR and AMR structures. In such embodiments, a TMR stack with a free layer functioning as an AMR structure is used. With a single such stack, contacted in different modes, a high-precision angle sensor with 360 degrees of uniqueness can be realized.
