The application discloses a service invoking method, device, apparatus and medium. The service invoking method includes: receiving a first service request message sent by a service invoking end; determining, in response to the first service request message, header information of the first service request message; determining, under a condition that the header information includes a route identification, a target data center among a plurality of data centers according to the route identification; sending the first service request message to the target data center to enable the target data center to provide service for the service invoking end. Based on the embodiments of the application, efficiency of service invoking can be improved.

A proxy server (700) receives, from a sending device, a packet intended for a receiving device (600). The proxy sewer (700) sends, to the receiving device (600), a promise frame (300) indicating that the proxy server (700) will deliver the packet to the receiving device (600) later. The receiving device (600) receives the promise frame (300) from the proxy server (700), and sends an acknowledgement of the packet to the sending device via the proxy sewer (700). The proxy server (700) forwards the acknowledgement of the packet from the receiving device (600) to the sending device, and delivers the packet to the receiving device (600) after having forwarded the acknowledgement to the sending device. The receiving device (600) receives the packet from the proxy server (700) after having sent the acknowledgement of the packet to the sending device via the proxy server (700).

Provided is a relay device including: a relay unit configured to perform a relay process for a frame transmitted and received between a plurality of function units; and a relay management unit. The relay unit receives, from a function unit, a target frame which is transmitted and received according to a predetermined communication protocol and includes information with which a request source of a service is identifiable and information with which a content of the requested service is identifiable, and the relay unit outputs the received target frame to the relay management unit. The relay management unit performs determination regarding setting change in the relay process of the relay unit, on the basis of the information included in the target frame received from the relay unit, and outputs the target frame to the relay unit or discards the target frame, according to a result of the determination.

This application discloses a peripheral component interconnect express (PCIe)-based data transmission method and apparatus. The method includes: A first node encapsulates data into a transaction layer packet (TLP) and then sends the TLP to a second node. The TLP includes a packet header and an extension header. The packet header includes a first field and a second field. The first field, the second field, and the extension header are used to indicate first encapsulation information. The first encapsulation information includes a data type of the data and at least one encapsulation parameter corresponding to the data type. In some embodiments, the first field, the second field, and the extension header are used to indicate the information required for transmitting the data.

A PCIe-based data transmission method and an apparatus are provided. The method includes the following: A first node obtains and sends a first TLP; and a switch receives the first TLP, and sends a second TLP to a second node. The first TLP includes a first TLP header and a first data payload, the second TLP includes a second TLP header and the first data payload, the first TLP header and the second TLP header are used to indicate a data type of the first data payload, and the data type of the first data payload includes at least one of audio, an image, control, data stream write, or security. The second node parses the first data payload based on the data type of the first data payload. This helps reduce communication complexity in a high-speed communication scenario.
