Problems solved by technology

However, the effective bandwidth of the WAN port is often much smaller than that of the LAN port, and data transmission is slow; more seriously, due to the large traffic on the LAN side, the WAN traffic is easily impacted by it, causing congestion; in addition, the traffic of the WAN port passes through the external network, compared with For LAN traffic, its delay and packet loss will be more serious

Embodiment 1

[0107] FIG. 4 shows a principle of receiving input data at an input port provided by the present invention.

[0108] The input ports are divided into priority input port groups and normal input port groups, and a port group can contain only one port. There may be a configurable parameter or register in the system to define which ports belong to the priority input port group (and the priority order or presence or absence of priority ports among the priority ports) and which belong to the normal input port group; or the port number can be used to determine Indicates the priority of the port (for example, port 0 represents the port with the highest priority), and the system can set an enabling parameter or register to configure whether to distinguish the port priority.

[0109] When no port belongs to the priority group or the function of prioritizing the input ports is not enabled, the input module only performs the polling method, which is functionally the same as the existing ...

Embodiment 2

[0118] Fig. 6, Fig. 7 and Fig. 8 show a realization principle of queuing scheduling provided by the present invention.

[0119] The queuing scheduling unit adds a priority output queue group to the existing normal output queue group to queue data from the priority input port or port group. Each queue in the priority output queue group may only correspond to one priority input port, or may correspond to multiple priority input source ports, or may even correspond to all priority input ports (at this time, the priority output queue group has only one priority output queue). There can be a set of configurable parameters or registers (which can also be reused for the input unit settings) to define which source input port data is to be enqueued to the priority output queue (and the priority or non-sequence between the priority output queues) ), the data of which source input ports should be enqueued to the normal queue output in the normal way, so as to determine the queuing destin...

Abstract

The utility model discloses a network data processing method and device; wherein, the method comprises: a plurality of input ends are configured with priorities; input data from the input ends with priorities or high priorities is exchanged and processed first according to the priorities of the input ends; data exchanged and processed is exported; the network device comprises: a priority configuration module, which configures priorities or high priorities to the input ends with smaller bandwidth or more important input ends; a data exchange module, which exchanges and processes input data from the input ends with priorities first; an output module, which exports exchange data. The utility model is applicable to the network device with important input ends to improve the transmission speed and quality of data from the important input ends.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a network data processing technology. Background technique [0002] Network devices such as switches, routers, and gateways are usually used for connections and interfaces between networks, such as between LANs (Local Area Networks, local area networks, local networks), between LANs and WANs (WAN Area Networks, wide area networks), etc., to complete multiple The exchange of data between two ports, the data (such as packets or cells) arriving at the input port is exchanged to the corresponding output port. When these network switching devices have multiple input ports to input data, they usually use polling (the method of selecting a port in turn from a group of ports, generally, if port n was selected last time, then this time Port selection (n+d), d>0;) Each input port receives data, after the data is forwarded and dispatched, it is queued and output at each ou...
