Embodiments of the present invention, which relate to the field of electronic technologies, provide a monitoring method, a monitoring apparatus, and an electronic device, which can accurately locate an error point in MPI information delivered by a system chip. The apparatus may include: an address filter, a read/write controller connected to the address filter, and a memory connected to the read/write controller, where the address filter is configured to acquire multiple pieces of MPI information, and obtain, by filtering the multiple pieces of MPI information, first MPI information corresponding to a first service that is preset; the read/write controller is configured to write, into the memory according to a time sequence of receiving the first MPI information, the first MPI information that is obtained by the address filter by filtering; and the memory is configured to store the first MPI information written by the read/write controller.

Monitoring microprocessor interface information for a preset service using an address based filter

A method and apparatus for implementing output queue-based flow control is provided. The method includes: implementing queue scheduling and flow control by using an output port-based cell queue and by counting the number of cells from different angles. In this system, the flow control and queue management are performed separately. The queue management is directly applied to the cell scheduling. The flow control does not directly depend on the cell statistical results in the queue management. Instead, it is implemented on the basis of the cell statistical results that are obtained according to the cell priority, output port and source chip number of the cells. Therefore, the provided method and apparatus may reduce and simplify the number of queues to be scheduled and implement fine and flexible back pressure control.
