Problems solved by technology

[0006] To sum up, the metric value of the network transmission path is very important for adjusting online services (such as video streaming services and content distribution services) to improve service quality and ensure user experience, but in the current complex business scenarios (client-side running Browsers and firewall settings cannot be completely consistent), how to accurately detect the measurement value of the network transmission path without increasing the load on the network transmission path that carries the business, there is no general and effective solution for related technologies

Embodiment Construction

[0036] The inventor found in the process of implementing the present invention that there is no effective solution for how to accurately determine the metric value of the one-way path, which is mainly manifested in the following aspects:

[0037] 1) The lack of metric values ​​for the underlying unidirectional path

[0038] The metric value of the underlying unidirectional path (which can also be regarded as an evaluation parameter) such as lost data packets (PacketLoss, that is, packets lost during transmission in a unidirectional path), out-of-order packets (PacketRendering, that is, transmission in a unidirectional path The order of arrival at the receiving end, packets inconsistent with the order sent at the sending end), jitter (Jitter) and bandwidth (Capacity) are critical to characterize the characteristics of a unidirectional path; but related technologies only support the detection of fewer types of metrics , such as round-trip time (RTT, Round-TripTime), Internet Tra...

Abstract

The embodiment of the invention discloses an information processing method and device. The method comprises: receiving a client's business data request packet; packaging the business data requested by the client into at least two detection packets, and sending the detection packets through a forward path; obtaining timing information, wherein the timing information includes a timestamp corresponding to the business data, a timestamp corresponding to the business data request packet and a time stamp corresponding to the data packet sent by the client through a backward path; and determining the one-way metric value according a path metric strategy and the obtained time stamps. Through adoption of the technical scheme of the embodiment, the information processing method and device are able to accurately detect the one-way metric value of a network transmission path in a complex business scene and cannot increase the load of the network transmission path used for bearing business.

Description

technical field [0001] The present invention relates to communication technology, in particular to an information processing method and device. Background technique [0002] The Internet Protocol (IP, Internet Protocol) business is growing rapidly and showing a trend of diversification. How to ensure the quality of data transmission on the IP network has become a problem that cannot be ignored. In order to solve this problem, related technologies use the network between the server and the client. Metrics of the transmission path, including packet loss (PacketLoss), out-of-order packet (PacketReordering), jitter (Jitter) and bandwidth (Capacity), to measure the quality of the network transmission path and make corresponding adjustments to improve service quality (QoS, QualityofService), guarantee user experience (QoE, QualityofExperiment); for example: [0003] 1) In a content distribution network (CDN, ContentDeliveryNetwork), the control server in the CDN can direct the cl...
