Embodiment
The present invention is described in further detail below in conjunction with drawings and Examples.
Referring to shown in Figure 1, each port of the Ethernet switching chip of power board links to each other with each integrated circuit board in the system respectively, and in fact data communication shows as the data retransmission between the corresponding port on the Ethernet switching chip of power board between integrated circuit board.All combinations according to data communication between integrated circuit board comprise clean culture, multicast and broadcasting, and the Ethernet switching chip port that is connected with each integrated circuit board is made up, and obtain a set, and each element in the set is one group of port.When system had n piece integrated circuit board, the Element of a set number was
For each element distributes a multicast, then the Ethernet switching chip of power board need be supported
Individual multicast.
Referring to shown in Figure 2, the method for controlling plane data interaction in distributed system of the present invention comprises the following steps:
A, system initialization: configuration control plane data are carried out all mutual combinations (all combinations point-to-point, point-to-multipoint delivery that the port that integrated circuit board is connected with the Ethernet switching chip of power board carries out) between integrated circuit board, and be that every kind of combination distributes a multicast, form the corresponding relation of data interaction port set and multicast, according to described corresponding relation, the ethernet port that the Ethernet switching chip of power board is connected with each integrated circuit board adds multicast, carries out the QoS configuration according to the data type of control plane transmission in the Ethernet switching chip of power board.Specifically in the process of system initialization, each port of Ethernet switching chip is determined VLAN and multicast table that this port need to add according to the plate card number that is attached thereto on the power board.
B, when control plane carries out data interaction, the source plate card that sends data is packet encapsulation ethernet frame head, contain the purpose multicast address in the ethernet frame head after the encapsulation, the ethernet frame that head is contained the purpose multicast address sends to the Ethernet switching chip of power board.For example, when certain piece integrated circuit board sends data to other integrated circuit board, data encapsulation to be sent is become ethernet frame, calculate VLAN and purpose multicast address according to purpose plate card number, after other fields of padding ethernet frames head, the ethernet frame after will encapsulating again sends to the Ethernet switching chip of power board.
Concrete, in the ethernet frame head of encapsulation: source address field is self-defined information, namely needs to send to the control information of purpose integrated circuit board; Protocol type field is packed ethernet frame data type partly, and the type of this data division comprises standard ethernet protocol type and self-defining data type.The virtual local area network tags territory comprises two parts: virtual local area network No. and precedence field.Precedence field in the virtual local area network tags territory obtains according to the qos policy of source plate card to processing data packets to be sent.Virtual local area network No. in purpose multicast address and the virtual local area network tags territory calculates according to the card number message bit pattern of purpose integrated circuit board.
After the Ethernet switching chip of c, power board receives the ethernet frame that described head contains the purpose multicast address, in multicast group, transmit or inundation (Flooding in VLAN according to described purpose multicast address or VLAN, the topological structure that does not require maintaining network calculates with relevant route, only requires to receive the node of information with broadcast mode forwarding data bag).
When the supported maximum integrated circuit board number of current system was n, the multicast number that the Ethernet switching chip of described power board need be supported was
The Ethernet switching chip of power board is operated in the pattern that unknown multicast wraps in inundation in the VLAN.If the integrated circuit board that system has is less, the multicast table number that the Ethernet switching chip of power board is supported greater than
Situation under, adopt multicast mode to carry out the data interaction of control plane.When system's integrated circuit board number increased, the multicast table number of the required support of Ethernet switching chip of power board was exponential increase.And generally speaking, the multicast table that exchange chip is supported is larger, and the price of exchange chip is higher.Therefore the multicast table number of supporting for the Ethernet switching chip of power board less than
And do not change the situation of Ethernet switching chip, then adopt the mode of VLAN+ multicast to carry out the data interaction of control plane, to reduce cost.
Describe method step of the present invention in detail below by 2 specific embodiments.

Step 103: the Ethernet switching chip of power board is transmitted in multicast according to the purpose multicast address of ethernet frame head, and is carried out the mapping of priority query according to 802.1Q after receiving ethernet frame after the encapsulation, and based on the QoS operation of stream.
Embodiment 2: system's integrated circuit board number is 16
Step 201: during system initialization, the Ethernet switching chip that power board is set is operated in the pattern that unknown multicast wraps in inundation in the VLAN; The data type that may receive is carried out the QoS configuration; Corresponding relation according to plate card number and multicast MAC and VLAN, determine multicast and VLAN that port adds, take system's integrated circuit board number as 16, the Ethernet switching chip multicast table number of power board is that 4K is example, and multicast scope and VLAN scope that the port that is connected with integrated circuit board n on the Ethernet switching chip of power board need add are:
{VLAN，MAC}＝{1，(01:00:00:00:00:00～01:00:00:00:0F:FF)|(1＜＜(n-1))}
VLAN＝(0x000～0x00F)|(1＜＜(n-1))+1
Step 202: when certain piece integrated circuit board sends data to other integrated circuit boards, data encapsulation to be sent is become ethernet frame, no matter this packet need send to one or polylith ply-yarn drill, the destination address of the ethernet frame head of power board is a purpose multicast address, according to purpose plate card number { n
1, n
2... calculate above-mentioned multicast address: 01:00:00:00:00:00| (1＜＜(n
1-1)) | (1＜＜(n
2-1)) ....The source address of ethernet frame is according to the actual requirements by User Defined.The information that the source plate card generally need to carry is write daily record sign etc. such as source plate card number, Flow Control sign, warning information.For above-mentioned ethernet frame adds VLAN and protocol type field.Vlan number calculates according to the above-mentioned purpose multicast address: the above-mentioned purpose multicast address
Totally 12 bits, i.e. [D
12: D
24] be vlan number, precedence field arranges 802.1Q priority according to the source plate card to the qos policy of these data; Protocol type is the type of above-mentioned data.Ethernet frame after the encapsulation is sent to the Ethernet switching chip of power board.
Step 203: after the Ethernet switching chip of power board is received ethernet frame after the encapsulation, purpose multicast address according to the ethernet frame head is transmitted in multicast, if the Ethernet switching chip of power board does not find multicast corresponding to this destination address, because the Ethernet switching chip of power board is operated in the pattern that unknown multicast wraps in inundation in the VLAN, therefore above-mentioned ethernet frame will be broadcasted in VLAN, and carry out the mapping of priority query according to 802.1Q, and operate based on the QoS of stream.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
