Embodiment Construction

[0028] The technical solution of the present invention will be described in detail below in conjunction with the drawings and embodiments.

[0029] Such as figure 2 As shown, a method for dynamically adjusting a link in an embodiment of the present invention includes:

[0030] Step 201, when the sending end detects that the data flow has changed, it determines link adjustment information according to the change of the data flow. The link adjustment information includes the required number of working links.

[0031] Step 202: The sending end adjusts the number of working links on the interface of the sending end according to the link adjustment information determined in step 201, and sends a configuration request to the receiving end, where the configuration request includes link adjustment information.

[0032] Step 203: After receiving the configuration request, the receiving end adjusts the number of working links on the interface of the receiving end according to the con...

Abstract

The embodiments of the invention disclose a method, a system and an apparatus for dynamically adjusting links. The method comprises the following steps: when detecting a variation of a data flow, a sending end determines link adjustment information according to the data flow variation, wherein the link adjustment information includes the amount of required work links; the sending end performs work link amount adjustment for the sending end interface according to the determined link adjustment information, and transmits a configuration request to a reception end, wherein the configuration request contains the link adjustment information; after receiving the configuration request, the reception end performs work link amount adjustment for the reception end interface in accordance with the configuration request. The embodiments of the invention adjust the work link amount when detecting the variation of the data flow, and do not affect the data transmission of the original work link during the period of adjusting the work link amount, thus saving the bandwidth and power consumption.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to a method, system and device for dynamically adjusting a link. Background technique [0002] With the rapid development of communication and chip technology, the demand for data exchange bandwidth between chips is increasing. However, due to packaging limitations and interference between buses, it is impossible to increase the width of parallel buses without limit to improve signal transmission bandwidth. In this case, the high-speed serial link technology is developing rapidly, and the device that completes data serial-to-parallel and parallel-to-serial conversion is usually called SerDes (Serializer and Deserializer). [0003] Interlaken is an interconnection protocol optimized for high-bandwidth and reliable packet transmission, which uses multiple SerDes links to establish logical links between devices, and utilizes multi-lane, backpressure capability, and data integrity prote...
