Problems solved by technology

However, the bandwidth of the logical channel will change dynamically. When the bandwidth of the logical channel increases, the speed of BD transmission will increase. If you continue to extract and store BD from the logical channel at the original rate, the logical channel will overflow.

Embodiment Construction

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art based on the present application belong to the protection scope of the present invention.

[0041] In order to prevent logical channels from overflowing, the embodiments of the present invention provide a BD scheduling method and device.

[0042] An embodiment of the present invention provides a BD scheduling method, the method includes:

[0043] Each clock cycle, determine the logical channel with the largest number of temporarily stored BDs among the logical channels mapped to the physical channel;

[0044] Select a logical channel from the detec...

Abstract

The embodiment of the invention provides a BD scheduling method and device, and relates to the technical field of networks, and the method comprises the steps: detecting a logic channel with the largest number of current temporary storage BDs in each logic channel mapped by a physical channel in each clock period; selecting one logical channel from the detected logical channels as a target channel; a preset number of BDs are extracted from the target channel, and the preset number is the total number of the BDs input into all the logic channels in each clock period. By applying the scheme provided by the embodiment of the invention, the BD in each logical channel can be scheduled, so that the logical channel is prevented from overflowing.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a BD scheduling method and device. Background technique [0002] After the switch chip in the network device receives the message, the switch chip can process the received message, and can search for the routing entry in the routing table that matches the destination address of the message, and convert the found route The address recorded in the entry is determined as the next-hop forwarding address of the message, and the message is forwarded according to the found forwarding address. [0003] During the period when the switch chip receives the message and finishes forwarding the message, the switch chip needs to store the message. In the prior art, the switch chip can process the received message into fragments, and generate a BD (Burst Descriptor, data slice descriptor) respectively recording the storage address of each slice, and the switch chip can store each data ...
