Background technology

Ethernet is by U.S. electric and (the Institute of Electrical and Electronics Engineers of Electronic Engineering Association, IEEE) standardized a kind of local area network (LAN) interconnection technique, the major technique standard of Ethernet defines in the normative document IEEE802.3 of IEEE issue.And Ethernet switch is a kind of data communications equipment of multiport, is used to finish the processing forward function of Ethernet message.Whether have device management software and the necessary management circuit module of running software according to device interior, Ethernet switch is divided into management type Ethernet switch and non-management type Ethernet switch two classes.

As shown in Figure 1, a managed switches mainly comprises three partial circuit modules: management circuit module, ethernet mac module and Ethernet PHY module.Wherein the management circuit module provides the operation platform of device management software, and device management software realizes the management of ethernet module is controlled by management interface, and by the indirect management control that realizes Ethernet PHY module of SMI interface.And the management circuit module also provides user's configuration interface, and the user carries out personalized configuration by this interface to every function of Ethernet switch.Ethernet mac (Medium Access Controller, medium access control system device) module is the data processing module of Ethernet switch, realizes the processing and the forwarding capability of Ethernet message, by the managed circuit control of management interface.Ethernet PHY (Physical Layer, physical layer) module is the signal transmitting and receiving module of Ethernet switch, receive physical signalling from ethernet port and convert message data to and give MAC by data channel and handle, accept message data that MAC transmits from data channel simultaneously and convert physical signalling to and send from ethernet port.MAC can pass through the state of SMI (Serial Manage Interface, serial management interface) inquiry and control PHY, so PHY also is that indirect managed circuit module is managed.

The management type Ethernet switch is because have the management circuit module, and the user can be configured by every function of configuration interface to equipment as required in site of deployment, to satisfy the application demand under the different application occasion.But the management circuit module is a miniature computer system in fact, must comprise central processing unit, random asccess memory, read-only memory or the like circuit module, so management type Ethernet switch complex structure, cost is high, uses in the application of cost sensitivity to be very limited.

Corresponding with it, a non-management type Ethernet switch general frame is as shown in Figure 2.Compare with the management type Ethernet switch, the Ethernet switch of non-management type is in full accord at the framework of ethernet mac module, Ethernet PHY module section.Non-management type Ethernet switch has not had the management circuit module on the whole, has only a memory of preserving basic configuration information, by equipment manufacturers before equipment dispatches from the factory with basic configuration information programming in memory, equipment reads basic configuration information by memory interface automatically in the initial stage ethernet mac module that powers on during use from config memory, finishes the initial configuration of MAC module and PHY module.This config memory generally adopts EEPROM (Electrically ErasableProgrammable Read-Only Memory, EEPROM (Electrically Erasable Programmable Read Only Memo)) to realize.

Retrieve application number 200810008144.6, " a kind of method and device that no webmaster Ethernet switch is carried out in-band management " in State Intellectual Property Office patent retrieval website; This method comprises: programmed logical module detects the mac frame of receiving in real time, judge whether to sending to the mac frame of self according to destination address, if programmed logical module converts the control messages in the mac frame to serial ports message, and communicate by letter with ethernet switching module or physical chip; Otherwise mac frame is transmitted to ethernet switching module, finishes current handling process; Programmed logical module becomes control messages with the serial ports message conversion of ethernet switching module or physical chip feedback, and sends the mac frame of execution result to the webmaster Ethernet switch.This utility model need be used and can weave into logic module and detect and management conversion control frame information, and can finish that mac frame detects and the programmed logical module of conversion too big cost advantage not than the management circuit module.

Application number 200710127571.1, " no webmaster Ethernet switch being carried out the method and system of simple management " said method comprising the steps of: (1) idle signal line by ethernet line links to each other the serial line interface of the CPU administration module of upper strata webmaster Ethernet switch with the serial line interface of the ethernet switching module of no webmaster Ethernet switch; (2) the CPU administration module of upper strata webmaster Ethernet switch is according to wherein configuration data, the ethernet switching module of no webmaster Ethernet switch carried out initialization register dispose and real-time control management.The unmanaged switch of indication in this utility model, still there is a single chip circuit to receive in fact and handles the managing configuration information that upper strata webmaster Ethernet switch sends, needing the support of software running platform in the equipment equally, is not to realize real configuration management at the Ethernet switch that does not have management software.Therefore can not realize minimumization of bottom switch cost.

Owing to deleted baroque management circuit module, and eprom memory commonly used is cheap, so non-management type Ethernet switch is compared the management type Ethernet switch and is had unrivaled cost advantage.The occasion of cost sensitivity has obtained using widely in that environment is comparatively simple.But the shortcoming that the exchange of non-management type Ethernet reaches is obvious too, the configuration information of switch by manufacturer before dispatching from the factory programming in the built-in memory of equipment, cannot change according to different application needs the site of deployment user, application flexibility is very poor.And in different application scenarios, the data terminal equipment that the user is different (as personal computer) all has different demands to isotypes such as the speed of ethernet port, dual-mode, flow controls, and manufacturer can not satisfy the demand of various different application patterns in the configuration information of programming in advance.Here it is unmanaged switch defective place in actual applications.

The utility model content

The purpose of this utility model is to overcome deficiency of the prior art, a kind of non-management type Ethernet switch framework is provided, this framework has acted on the low-cost advantage of non-management type Ethernet switch, possesses simultaneously the advantage that the management type Ethernet switch can on-the-spot flexible configuration again.

The technical solution of the utility model is: a kind of scene configurable non-management type Ethernet switch, comprise ethernet mac module, config memory module, on the access interface of ethernet mac module accesses config memory, insert a commutation circuit, the access interface of config memory optionally is connected on the ethernet mac module or external user's configuration interface in the switch.Under normal mode of operation, the access interface of config memory disposes with external user and is connected disconnection, but be connected to the interior ethernet mac module of switch, device power initial stage MAC module reads manufacturer programming in advance by this interface from memory, or the user is according to the configuration information that application need writes, and runs well according to this configuration information after finishing the initialization of MAC module and PHY module.When needs write new configuration information, the access interface of the handover configurations memory by commutation circuit and ethernet mac module be connected disconnection, and the access interface of memory is connected on the external user's configuration interface of switch, the user will be written in the config memory of switch inside according to the configuration information that application need is write by this configuration interface.User's configuration interface external in this commutation circuit has precedence over the ethernet mac module interface, in case external user's configuration interface is connected with config memory, the ethernet mac module just disconnects and being connected of config memory; External user's configuration interface is connected disconnection with config memory, the ethernet mac module just automatically with being connected of config memory.
