Description
Technical field
The present invention relates to a kind of modular switch, especially relate to a kind of Redundancy Management System switch, belong to data communication technology field.
Background technology
The effect of switch mainly is to be used for the forwarding of user data to handle.There is the Ethernet physical interface of various ways at present, can be divided into 10M, 100M, 1000M or 10000M etc. by measure; Press transmission medium beam split mouth and electricity mouth etc.Present many switches adopt modular project organization, for improving the reliability of system, can adopt the design of managing redundant.Managing redundant in the switch is specially, and adopts two management boards, and wherein one is the main management plate, bears the management and the data exchanging function of system; Another piece is from management board, is in normal operating conditions at ordinary times, not participative management and exchanges data.When finding main management plate fault from management board, can take over administrative power at once, safeguard normal operating state to guarantee whole system.
Traditional modularization, the switch of managing redundant all adopt the mode of dual link, are about to data, management path and two management boards and all set up physical connection.As Fig. 1 is a kind of framework explanation of traditional modular switch, and in the conventional switch, business module is by central processing unit (CPU), exchange chip (SWITCHIC) and physical chip (PHY) composition.Administration module is made up of CPU and SWITCH IC.The effect of CPU mainly is the management and the configuration of administration module or Switching Module; It is that forwarding of data is handled that SWITCH IC mainly acts on, and the decision message to which port is transmitted; The effect of PHY is to be the coding form of physical interface transmission with data conversion, as the form that need be converted into MLT-3 for 100,000,000 electric Ethernet interfaces (multilevel transmission coding in MLT-3:3 rank is the standard code of 100,000,000 electric Ethernet interfaces of international IEEE (I EEE) regulation).In order to realize the redundancy backup of double-pipe type module, business module all need have physical link to be connected with two administration modules, for fear of the generation systems loop, a link job can only be arranged, an other link-down simultaneously.When a link occurs fault, switch to an other link job.So all the time, there is a link to be in off position, will wastes system bandwidth like this, also increased the complexity of system design simultaneously.
Secondly, in order to finish the bookkeeping of administration module, administration module includes CPU; In addition because administration module is being born the data forwarding of trans-sectoral affair module simultaneously, so must comprise SWITCHIC in the administration module.And parts such as CPU, SWITCH IC and PHY have also been comprised in traditional business module.Because it is overlapping that the part of business module and administration module exists, so caused the increase of cost.
Summary of the invention
The objective of the invention is at above-mentioned prior art in order to realize managing redundant, business module directly is connected with two administration modules that are used for masterslave switchover, and the defective of the system bandwidth that causes waste, a kind of modular switch of architecture advances has been proposed, to make full use of system bandwidth, improve resource utilization.
For achieving the above object, the present invention proposes a kind of modular switch, comprise: two administration modules, and at least one business module, wherein also comprise: Multiplexing module, cochain link by business module is connected with business module, is used for described cochain link is copied as active link and copy link; Be connected with described two administration modules respectively by active link and copy link; Multiplexing module also comprises: on-off controller is used to carry out the switching of active and standby administration module; Described administration module comprises CPU module and SWITCH module; Described business module only comprises the PHY module.
In the technique scheme, by between administration module and business module, introducing Multiplexing module, adopt Multiplexing module that the cochain link of business module is duplicated expansion, be connected with two administration modules respectively by duplicating the active link and the copy link module that obtain then, the bandwidth of the link between Multiplexing module and each administration module and the cochain link bandwidth of business module are consistent, thereby all cochain links of logically having realized business module all are connected with an administration module, all cochain links that guaranteed business module all can be fully used, to realize making full use of system bandwidth, improve the purpose of resource utilization and reduction system cost.
