Abstract: Embodiments relate to optical transport technologies, and more specifically, to a clock transmission method. Under this method, a first optical data unit (ODU) container can be obtained. Phase discrimination can be performed on an obtained first clock and a first ODU clock of a transmit end, to generate a first PD value. The first PD value can then be inserted into an overhead of the first ODU container. The first ODU container can be encapsulated into a second ODU container, and the second ODU container can be sent. A rate of the second ODU container is higher than a rate of the first ODU container. The first PD value is transmitted in the first ODU container which is not decapsulated in a subsequent transmission process. Therefore, final recovery of the first clock is not affected, so that a deviation between a finally recovered clock and the first clock is greatly reduced.

Abstract: Embodiments of the present invention provide a method, an apparatus, and a system for determining a policy and charging rule function entity. The method includes: receiving, by a first PCRF, a first request message transmitted by a first routing agent device, where the first request message carries an IP address of a user; inquiring a pre-stored corresponding relationship between the IP address of the user and an identity of a PCRF currently serving the user according to the IP address of the user, and determining an identity of a second PCRF currently serving the user; and transmitting a message carrying the identity of the second PCRF to the first routing agent device. The method realizes that session information of the same user can be routed to the same PCRF when a biplane DRA is under a multi-PCRF networking, and provides reliable DRA signaling network networking.

Abstract: A method and a network device for managing Diameter routing are disclosed in the communication technology. The network device avoids frequently sending a Diameter message on a faulty routing. In the method: a network apparatus receives a first Diameter message configured to be delivered to a destination node. The network apparatus determines a routing status of a primary routing from the network apparatus to the destination node according to recorded routing status from the network apparatus to the destination node. The network apparatus sends the first Diameter message through the primary routing if the routing status of the primary routing is normal. The network apparatus sends the first Diameter message through an alternative routing from the network apparatus to the destination node if the routing status of the primary routing is faulty.

Abstract: Embodiments of this application disclose an interpolation filter training method and apparatus, a video picture encoding and decoding method, an encoder, and a decoder. According to the training method, a first sub-pixel picture obtained through interpolation by using a conventional interpolation filter is used as label data, to train a second interpolation filter, so that the second interpolation filter obtained through training can be directly used for a pixel value, obtained through interpolation, of a first fractional pixel position. Therefore, the label data is more accurate, and coding performance of a video picture is improved. According to the encoding method, during inter prediction, a target interpolation filter used for a current encoding picture block is determined from a set of candidate interpolation filters, and the encoder selects, according to content of the current encoding picture block, an appropriate interpolation filter to perform an interpolation operation.

Abstract: A baseband data transmission system includes a first sending path and a second sending path that have different performance indicators. A first switching unit selects an output of one of the sending paths based on a type of a to-be-transmitted data packet, and sends the output to a sender. In this way, when there is to-be-transmitted data of a plurality of different types, the output of the appropriate sending path may be selected by using the first switching unit without rebooting the data transmission system or performing link renegotiation, so that hybrid transmission of data packets of a plurality of types in the system is implemented.
