Embodiment Construction

[0033] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] refer to figure 1 As shown, the RED hardware implementation device of the present invention is described in detail.

[0035] The RED hardware implementation device includes a data interface module, a management memory control module, a RED judgment module, and a group memory control module.

[0036] The data interface module is the bus interface of the data flow, responsible for receiving the data flow, and extracting the data flow identifier as an index of the management memory, and discarding the packet or storing the packet in the external packet memory according to the calculation result of the RED judgment module.

[0037] The management memory control module is an external management memory control device, which is used to manage the writing and reading of the management memory.

[0038] The management memory is used to store...

Abstract

The method comprises: data interface module receives the data stream, and according to the ID field of data stream, extracts the data stream ID, and takes the data stream ID as the index to write the information correlated to the current packet to the external management storage; RED estimation module takes said current data stream ID as index, and gets the information correlated to current packet from said management storage, and according to the information correlated to current packet, gets the estimation result, and saves said estimation result; said data interface module reads out said estimation result; if the estimation result of current packet is to abandon the current packet, then the current packet will be abandoned; if the estimation result of current packet is to receive the current packet, then the current packet will be received, and said current packet will be written into the external packet storage. The invention also reveals an apparatus thereof.

Description

technical field [0001] The invention relates to an IP communication technology, in particular to a random early detection device in QOS (Quality of Service) and a hardware implementation method thereof. Background technique [0002] In recent years, with the rapid development of information technology and the massive increase of network applications, the existing huge data transmission volume has doubled. Optimizing bandwidth is an important means to meet the growth of data transmission volume. Congestion control is an important means of communication to optimize bandwidth. TCP's window-based end-to-end congestion control plays a key role in the stability of the Internet. However, with the rapid development of the Internet, its network scale is getting larger and its structure is becoming more and more complex. It is not enough to rely solely on end-to-end congestion control. The network must participate in the control of resources. [0003] Random Early Detection (RED: R...
