Embodiment
Describe one embodiment of the invention with reference to the accompanying drawings in detail.
In network system, unique server that is present in the sub-network has dual mode: mode (dispersing mode) mode (server mode) of allocation manager and serverless backup, determined inherent address by each node self-discipline is carried out in the full address of node in the sub-network.
Address decision method in the network of present embodiment is characterised in that, comprises respectively that in these server modes and dispersing mode new node determines the method for intrinsic lower layer address and shortens the method that determines lower layer address required time as far as possible.In addition, so-called lower layer address is meant the address that should remain on lower layer L3 of protocol stack shown in Figure 3, it be in all nodes that started that are assigned in the sub-network, in sub-network, belong to unique a kind of address, the world.Again, last bit address is determined uniquely by the lower layer address, does not here elaborate.Before action is obtained in the lower layer address, in the sub-network unique IP address obtain end, this is obtained end as the trigger point, move to the action that obtains of lower layer address.Again, hardware address is set at unique value with each transfer medium during fabrication in advance.
As shown in Figure 4, each node 100 that comprises server be by transfer medium, modulation that digital signal transmits usefulness reconcile loop 1, by the program executive address distribute, management and other microcomputer 2, EPROM (erasable read-only memory) 3, ROM (read-only memory) 4, RAM (random access memory) 5 each key element of fixed s operation control as non-volatility memorizer constituted.And determine by the software program executive address.
Fig. 5～Figure 10 represents the packets of information of Data transmission between the interior node of network.Wherein, the implication of " intrinsic " speech among the figure is the node (node that also comprises server) that this packets of information is delivered letters, and the key element of each packets of information shows with the position of 1 byte unit.
When new node occurring, from lower layer L3 output initialization information bag shown in Figure 3.As shown in Figure 5, initialization information bag A by address A1, inherent address A2, packets of information type A3, reply type A4, intrinsic hardware address A5, interim lower layer address each key element of A6 is constituted.Wherein, as address A1, write IP multicast address in the sub-network; As inherent address A2, write intrinsic IP address.And, writing of packets of information type A3 arranged promptly but the write occasion or packets of information type A3 and the type A4 of replying of no response type A4 all write occasion according to following two kinds of occasions, discern full node and reply and require or only server acknowledge requirement.Again, the setting means by hardware switch and software etc. carries out full node to new node in advance and replys and require or only replying of server requires to make setting in new node.That is, when each node enters network, can select to carry out full node by the user or the person of setting and reply the requirement of replying that requires or have only server.
The node that receives initialization information bag A is discerned the full node of replying still of server only according to writing of the type of replying that has or not this initialization information bag A.If the type of replying is only replying of server, then initialization response packet shown in Figure 7 is returned.Promptly belong to full node as if writing of paid-in initialization information bag A no response type and reply, then the node beyond the server returns initialization response packet B shown in Figure 6, and server returns initialization response packet C shown in Figure 7.
Initialization response packet B shown in Figure 6 is made of address B1, inherent address B2, packets of information type B3, each key element of replying type B4, intrinsic hardware address B5, interim lower layer address B6.Initialization response packet C shown in Figure 7 by address C1, inherent address C2, packets of information type C3, reply type C4, intrinsic hardware address C5, intrinsic lower layer address C6, each key element of giving lower layer address C7 constituted.
In these initialization response packets B, C, address B1, C1 represent the IP address of the source node of delivering letters of initialization information bag A, inherent address B2, C2 represent intrinsic IP address, packets of information type B3, C3 or reply type B4 and the type C4 of replying represents the packets of information of being collected mail by the code that writes wherein is the packets of information returned from server or discerns from the packets of information that general node returns, and be replying of a kind of initialization information bag A.These initialization information bags B, C comprise intrinsic hardware address B5, C5 and intrinsic lower layer address B6, C6.Again, if the initialization response packet from server, then this initialization information bag C comprises the lower layer address C7 that gives new node.
To be this node reply with respect to accepting of returning from the lower layer address of server packets of information D shown in Figure 8, is made of address D1, inherent address D2, packets of information type D3, each key element of replying type D4, intrinsic hardware address D5, intrinsic lower layer address D 6.The address D1 of this packets of information D promptly is the IP address of server.
Packets of information E shown in Figure 9 is a kind of packets of information of multicast in sub-network behind the interim lower layer address that determine, address E1, the expression that it comprises multicast deliver letters inherent address E2, the packets of information type E3 in source, intrinsic hardware address E5 and interim lower layer address E5.The node of accepting interim lower layer address E5 by this packets of information E is as if identical with intrinsic lower layer address, and the IP address in the source of then will delivering letters notifies the packets of information F of usefulness to deliver letters as address F1 to shown in Figure 10 repeating.This packets of information F is made of each key element of address F1, inherent address F2, packets of information type F3, intrinsic hardware address F4, intrinsic lower layer address F5.
Below to the determining method (A pattern) of some lower layers address of serverless backup of the present invention with determine each concrete action of the method (SR pattern) of lower layer address to describe reliably by server.In addition, A pattern and SR pattern can preferably be decided according to web application by switchings such as hardware switch or software set instruments.That is, according to network size, the transmission occupation rate permission and have or not the manager to decide of decision network application.In general, big in scale, do not have transmission occupation rate permission but recommend to select the SR pattern when manager is arranged, condition in addition then recommends to use the A pattern.
Figure 11 is the program diagram of the lower layer address decision order when carrying out the SR pattern of each node.In the SR pattern, must be by the server-assignment lower layer address that has started.In case when node that has started and the communication disruption between new node or server stopped, the server no response in this pattern, finished as makeing mistakes.In this occasion, reset in order to make server, need the manager to get involved.
New node carries out multicast (S1) to initialization information bag A shown in Figure 5.It is made reply, only initialization response packet C shown in Figure 7 is returned (S2) from the server that has started.The new node that receives this initialization response packet C is made by packets of information D shown in Figure 8 and being replied, and determines the lower layer address.
Figure 12 is the program diagram of the decision order of the lower layer address when carrying out the A pattern of each node.In the A pattern, if new node is multicast initialization information bag A (S11), and then all nodes that started (also comprising server node) in the sub-network return initialization response packet B or C (server occasion) (S12).
At this, even there be not reply (not having initialization response packet C this moment) from server, new node also can be from decision interim lower layer address in the lower layer address the intrinsic lower layer address B6 that from the initialization response packet B of paid-in each node, comprises being used for new node, the node that has started that the initialization response packet B that comprises this value is respectively returned carries out multicast (S13) as the packets of information E of address.
For the packets of information E of this multicast,, then repeat notice (S14) by packets of information F executive address if be judged as a certain node that has started and the repetition of intrinsic lower layer address.In a single day new node receives this address and repeats notice, then except returning the address that the letter address group repeats with described, resets interim lower layer address, carries out the multicast of S13, waits for returning of repeating to notify.
Fix time not yet to return and repeat to notify if passed through institute, then determine (S16) as this address with predefined interim lower layer address from the multicast of S13.
On the other hand, among the S11, by multicast when new node is delivered letters initialization information bag A, if the server of the node that has started in the sub-network has by replying of carrying out of initialization initialization information bag C (S12 '), then new node is given lower layer address C7 as intrinsic lower layer address (S17) with what comprise among this initialization response packet C.In this occasion, can under the situation of not carrying out packets of information B, E, F transceiver, make determining of lower layer address immediately.Like this, even the A pattern also can be carried out the lower layer address assignment fast.
In the address decision method of the network of present embodiment, occasion whatsoever, two kinds of different packets of information that all can be by the new node multicast in sub-network that is prepared in advance (partial code of change initialization information bag A number) difference is used the method (A pattern) of the arbitrary lower layer of decision address and is determined the method (SR pattern) of lower layer address by server reliably.And as long as the node that has started is replied according to the initialization information bag from this new node, new node just can determine the lower layer address by SR pattern or the A pattern of selecting in advance.
At this, the address decision method of SR pattern be because of only need getting final product dealing with between per 1 new node and the server, thus be a kind of transmission less and stable method, even the network of being made up of many nodes does not have weak point yet.On the other hand, the address decision method of A pattern is because of being that per 1 new node all needs from full node echo reply, so transmission occupation rate height is not corresponding with the network of being made up of many nodes.But in the present embodiment,, therefore, can have and select and change simply the corresponding address determining method owing to just partly change the Code Number of initialization information bag A according to the scale of network.
When having server, wish that certainly new node accepts the lower layer address assignment as early as possible again.In order to address this problem, the following describes with the communication of Fig. 1, master/slave mode shown in Figure 13 and communicating by letter with Fig. 2, CSMA/CD mode shown in Figure 14.
In Fig. 1, master/slave mode shown in Figure 13, carry out communicating by letter of a plurality of slave nodes and 1 host node with the timing section, host node number leaves in each slave node in order, and and specific slave node between carry out the packets of information exchange.Yet, receive information the host node of bag if know in advance which 1 slave node is its packets of information be sent to from slave node, can the shortest time this packets of information be delivered to the purpose slave node.
Because should become the node of server is unique in sub-network, pretends the lower layer address of using for this server node and has determined 1 reservation value.And, when new node is slave node, the host node that receives its packets of information A that delivers letters is sent to the slave node (or not needing to transmit) with lower layer address subscription value immediately when host node itself has the reservation value, as to its reply, can from server node initialization response packet C be back to the new node in the source of delivering letters immediately with lower layer address subscription value.
As shown in figure 15, host node was finished the admin table 10A, the 10B that comprise IP address, hardware address, lower layer address, subordinate management number at least of the slave node under the management before obtaining the lower layer code, remain on ROM5 or the EPROM3, can be distributed in the slave node address suitable with lower layer address subscription value.At this, the reservation value is write in the server node in advance, as the lower layer address value, host node reads in it with IP address and hardware address, and is reflected on the admin table 10B of Figure 15.In the admin table 10B of Figure 15, the lower layer address is write as 0x00, even consequently main point of contact itself is a slave node, also can immediately initialization response packet C be back to the source of delivering letters.
Communication to Fig. 2, CSMA/CD mode node shown in Figure 14 describes below.In this mode, do not have special master/slave notion, the node of wanting to deliver letters carries out carrier wave and detects when being about to deliver letters, if on transfer medium carrierfree, then deliver letters to node arbitrarily.In this network, by will from receive initialization information bag A till initialization response packet B or C are delivered letters during as the time of giving by " lower layer address value * set time ", the packet conflict that takes place in the time of can avoiding a plurality of nodes to send packets of information simultaneously.With its simultaneously, by the lower layer address value of server node is the minimum value of common node less than other as the decision of reservation value, server node can be sent initialization response packet C the earliest.That is, new node can obtain the lower layer address at short notice.
Like this, but server will be the minimum value of lower layer address setting range as the reservation value decision of lower layer address value, and, particularly in master/slave mode, host node leaves in the reservation value of lower layer address value immediately and carries out delivering letters and the collection of letters of initialization response packet C of initialization information bag A; In the CSMA/CD mode, because each node is at the rule of communication of replying as packets of information in the time of giving that amasss of lower layer address value and set time, new node can be accepted the distribution of lower layer address at short notice when having server.
Again, initialization response packet B shown in Figure 6 can notify the more suitable node address that has used by additional following information.Other Activity On the Node position admin tables 11 shown in Figure 16 are exactly the tables of data that keeps each node.This tables of data is made up of the key element of activity bit, each node hardware address and timer.Activity bit with the next layer address number by being stored on RAM5 to big order from little, for example, initial memory address number expression lower layer address=0, the 2nd address number represented lower layer address=1, if there is corresponding address, activity bit=1 of corresponding address number for example then, if do not exist, then definition is activity bit=0 etc.Again, the hardware address of the node corresponding with each lower layer address also is consistent.Again, the corresponding activity bit of the source of the delivering letters hardware address of the packets of information that each node receives at last has the countdown timer respectively, and the countdown timer is reset to initial value when the suitable packets of information of source hardware address is delivered letters in each acceptance.And this timer counting begins to reduce from this initial value, becomes institute's definite value when following, activity bit=0.
As shown in figure 17, the activity bit of tables of data 11 of management like this is additional to initialization response packet B, is notified to new node, the more definite lower layer address of having used just can be provided by the lower layer address value that will use.In addition, the data of these tables of data 11 are removed when node restarts and are made.
