Problems solved by technology

When the external storage bandwidth is insufficient, most designs adopt the strategy of bandwidth allocation in advance, but the time delay is large, and after the buffer is exhausted, non-congested high-priority packets may also be discarded

Embodiment 1

[0074] The built-in memory has the characteristics of large bandwidth and small capacity. Correspondingly, the peripheral memory has a small bandwidth and a large capacity. Such as image 3 As shown, in the present invention, all incoming messages are stored in the built-in memory, and do not directly go to the peripheral memory (such as image 3 shown in data flow 1).

[0075] If the authorization is issued in a timely manner and the built-in memory does not generate message accumulation, then the message will always stay in the built-in memory before being dispatched out of the queue. image 3 Shown in data flow 2), its bandwidth is large enough.

[0076] If the authorization is not issued in time, the built-in memory will generate message accumulation. When the accumulation reaches a certain threshold (this threshold can be configured arbitrarily), the message that first entered the built-in memory will be moved according to the time sequence of the messages entering the...

Abstract

The invention provides a message storage method and device, and relates to the field of data communication, and the message storage method comprises the steps: when the message accumulation capacity of a built-in memory meets a preset condition, messages cached in the built-in memory are moved to a peripheral memory according to a time sequence; And in the process of moving the message, when the peripheral memory reversely presses the moving path, the message moving to the peripheral memory is discarded. The method can effectively ensure that a large-bandwidth built-in memory is used by usinga high-priority message, a low-priority message is moved to an external memory when being congested, and the bandwidth of the internal memory and the capacity of the external memory are effectively utilized according to the high-priority operation and the low-priority operation in the storage link.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a message storage method and device. Background technique [0002] As networks continue to grow, the bandwidth demands of service providers and data centers are increasing at an unprecedented rate. Facing new demands and challenges, new equipment must be quickly developed and brought to market, and required to maintain high availability while reducing overall operating costs. [0003] However, for the core backbone network, the current bandwidth development of storage technology has encountered a bottleneck. DDR (Double Data Rate, double-rate synchronous dynamic random access memory), QDR (Quad Data Rate, quadruple Both High Bandwidth Memory, high-bandwidth video memory) and HMC (Hybrid Memory Cube, hybrid storage cube) cannot meet the storage bandwidth requirements of Tbps level on the core backbone network. [0004] Facing the fact that the current storage devices cannot mee...
