Various methods and systems for implementing request scheduling and processing in a multi-tenant distributed computing environment are provided. Requests to utilize system resources in the distributed computing environment are stored in account queues corresponding to tenant accounts. If storing a request in an account queue would exceed a throttling threshold such as a limit on the number of requests stored per account, the request is dropped to a throttling queue. A scheduler prioritizes processing requests stored in the processing queue before processing requests stored in the account queues. The account queues can be drained using dominant resource scheduling. In some embodiments, a request is not picked up from an account queue if processing the request would exceed a predefined hard limit on system resource utilization for the corresponding tenant account. In some embodiments, the hard limit is defined as a percentage of threads the system has to process requests.

A system for controlling power distribution within a vehicular communication network, including a power source equipment comprising a first port in communication with a network node module of a device, and a Power over Ethernet (POE) management module. The POE management module is configured to enable POE to the device via the first port, monitor a current draw of the device, determine whether the current draw of the device exceeds a threshold, and disable POE to the device, responsive to determining that the current draw exceeds the threshold.

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.

A communication control device stores reception data received from a network in any one of a plurality of reception queues to which different priorities have been given in advance to transfer the reception data to a main memory. The communication control device includes a reference table and a selection unit. In the reference table, at least one of a source address, a destination address, and an Ethernet frame type of the reception data to be stored is defined for at least one of the plurality of reception queues. The selection unit selects a reception queue in which the reception data is to be stored with reference to the reference table using at least one of the source address, the destination address, and the Ethernet frame type of the reception data.
