This application provides a method for constructing a blockchain network based on an interior gateway protocol (IGP). A new IGP packet used to transmit a blockchain task is provided by extending the IGP. When receiving the new IGP packet, a network device can participate in execution of the blockchain task by using its idle computing power. The computing power of the network device is better utilized to construct the blockchain network, avoiding a waste of idle computing power of the network device.

A service invocation method and a network device are provided. The method applied to a service provider side includes: receiving a service request for a first service by a provider of the first service, the service request being sent by a service consumer; sending a service response for the first service by the provider of the first service to the service consumer, wherein the service response for the first service includes service invocation information or a service invocation result of at least one second service associated with the first service, the service invocation information is configured to instruct the service consumer to invoke the second service.

In some implementations, a device may receive a SIP invite associated with a call to a first user device from a second user device. The first user device may be associated with a first network and the second user device may be associated with a second network that is separate from the first network. The SIP invite may include an identity header that indicates a carrier identifier associated with the second network. The device may authenticate the call based on a caller identification associated with the second user device and the carrier identifier. The device may send, based on authenticating the call, the SIP invite to the first user device to indicate, in association with receiving the call and via a user interface, an authorized entity associated with the carrier identifier according to the SIP update.

An apparatus is provided for classifying content in one or more transactions. The apparatus includes a transaction boundary detector to detect boundaries of the one or more transactions associated with a first server or a first destination, wherein the one or more transactions include one or more requests from a client or a source and one or more corresponding responses from the first server or the first destination. A multimedia session generator generates a multimedia session object based on the detected boundaries of the one or more transactions. A multimedia classifier classifies the content associated with a first multimedia session. A traffic processing and policy enforcement unit applies traffic management to the first multimedia session based upon the classification.

Methods and apparatuses for scheduling and indicating scheduling information in a wireless local area network (WLAN). A station (STA) includes a transceiver configured to receive a header for a protocol data unit and a controller configured to identify common information for a plurality of STAs that are scheduled in the WLAN from a common field in the header and to identify user-specific information for the STA from a user-specific field in the header that follows the common field. An access point (AP) includes a controller configured to include common information for a plurality STAs that are scheduled in the WLAN in a common field in a header of a protocol data unit, and to include user-specific information for the STAs in a user-specific field in the header that follows the common field. The AP also includes a transceiver configured to transmit the protocol data unit including the header.
