Description
Technical field
The present invention relates to communication technical field, more particularly to a kind of interface allocation method, master card and high-speed daughtercard.
Background technology
With the variation of communication service species, the framework of communication equipment also becomes increasingly complex.It is therefore desirable to communication equipment
The processing and forwarding of big data quantity can not only be completed, and the processing and forwarding of small data quantity can be completed.This just needs to communicate
The master card of equipment both it is pluggable support big data quantity processing and forwarding high-speed daughtercard, also it is pluggable support small data quantity place
Reason and the low speed subcard of forwarding.For example, 10Gbps ether subcard (high-speed daughtercard), also grafting are plugged with the master card of router
There are 2.048Mbps E1 subcards (low speed subcard).
At present, it is plugged on the situation of a communication equipment simultaneously for high-speed daughtercard and low speed subcard, there are two kinds of design sides
Case：Scheme 1, the grafting high-speed daughtercard on the high speed groove position of the master card of communication equipment, grafting low speed subcard on low speed groove position；Scheme
2, design high-speed interface and low-speed interface simultaneously in each groove position of the master card of communication equipment so that each groove position can insert at a high speed
Subcard, it can also insert low speed subcard.
Below so that a master card supports two groove positions as an example, both schemes are respectively described below：
In scheme 1 as shown in Figure 1, two groove positions of master card 10 are high speed groove position 102 and low speed groove position 103 respectively.Its
In, connection high speed groove position 102 and the data/address bus of central processing unit (Central Processing Unit, abbreviation CPU) 101
It is Ethernet Attachment Unit Interface (Ethernet Attachment Unit Interface, abbreviation XAUI) bus (in such as Fig. 1
Shown in A), connection low speed groove position 103 and CPU101 data/address bus is Serial Gigabit Media Independent Interface (Serial
Gigabit Media Independent Interface, abbreviation SGMII) bus (as shown in B in Fig. 1).Due to high-speed daughtercard
11 interface bus is XAUI buses, therefore high-speed daughtercard 11 can only be plugged on the high speed of master card 10 by high-speed daughtercard plug-in unit 111
On groove position 102；The interface bus of low speed subcard 12 is SGMII buses, therefore low speed subcard 12 can only pass through high-speed daughtercard plug-in unit 121
It is plugged on the low speed groove position 103 of master card 10.Therefore, the program requires that user has to identify high-speed daughtercard and low speed exactly
Subcard, and high speed groove position and low speed groove position, and correct grafting, communication equipment could normal works.Otherwise, high-speed daughtercard is inserted
It is connected on low speed groove position, or low speed subcard is plugged on high speed groove position, communication equipment all can not normal work.Obviously, mother is worked as
When the high speed groove position of card is broken down, user can not just use high-speed daughtercard, if now user does not have low speed subcard, and only have
High-speed daughtercard, the low speed groove position of that master card also can not just utilize.Therefore, the low speed groove position of master card is at idle condition, does not have
It is fully used.So the program is because high-speed daughtercard and low speed subcard are unable to mixed insertion, thus the easy of communication equipment can make it that
Reduced with property, while when there are special circumstances, the wasting of resources is also larger.
In scheme 2 as shown in Figure 2, each groove position of master card 20 be designed with simultaneously XAUI buses (as shown in A in Fig. 2) and
SGMII buses (as shown in B in Fig. 2), XAUI buses and SGMII buses are respectively defined on the different pins of groove position interface 202.
The XAUI buses of high-speed daughtercard 21 and the SGMII buses of low speed subcard 22 are respectively defined in and 202 corresponding pin of groove position interface
On.Therefore each groove position both pluggable high-speed daughtercard 21, also pluggable low speed subcard 22, without repartitioning high speed groove position and low speed
Groove position.Therefore in this scenario, high-speed daughtercard and low speed subcard can work on all groove positions of master card.But with the phase of scheme 1
Than the resource such as SGMII buses, XAUI buses in scheme 2 needed for master card 20 all increases into multiple.And each groove position is in grafting height
During fast subcard, the SGMII buses of the groove position would be at idle condition；In grafting low speed subcard, the XAUI buses of the groove position
It would be at idle condition.Therefore the wasting of resources of the program is larger.
Therefore, seek that a kind of ease for use is higher, while and can makes full use of the method for interface of interface bus resource, is
Technical problem urgently to be resolved hurrily at present.
The content of the invention
