Physically, server and terminal equipment all are the physical nodes with Internet IP address or internal network IP address that is connected on the IP network.Logically, after the operation topology agreement, whole network has formed in many higher levels of a fraction node classification, every, the layer, the logical construction of interlayer operation topology completeness maintaining agreement.Except the root node circle was server, other each layer nodes were terminal equipment.Root node and Servers-all that the server node is in the whole logic after the formation have formed a root node circle.
Detailed description is based on the leaf of dynamic topology agreement and the process of server structure dynamic network topology.Dynamically to close on the border be the logic topology network that the circle by different brackets constitutes to topology.The foundation of network hierarchy is the numeric string of each terminal equipment regular length of default allocation in dispatching from the factory, and is referred to as the ID or the number of terminal.In minute circle and classification process, to observe a principle: divide in the circle each, the preceding N position of the ID of the terminal equipment in the same circle identical (N in this subtracts 2 from 0 regular length to numeral), preceding M (M gets 1 to the N-2) position that the upper level circle is compared in the preceding N-2 position of this circle is identical, and the numeral of M position is identical with preceding M bit digital at the corresponding levels before the higher level.In fact this branch circle classification principle makes the logical network topology have such feature: because two digits difference in each circle, so each circle adds its immediate superior node, total nodal point number can not surpass 100.Set up from level to level with such classification principle and just to have formed final topological structure.This is the basic principle of hierarchical network, and promptly normal state still in network operation process, can occur the localized network topology different with this principle under certain condition, is referred to as anomalous mode, and anomalous mode can preferentially be returned normal state under the situation that network condition satisfies.By above-mentioned classification principle as can be known, under the situation of 10 bit digital, the classification principle of every grade 2 bit digital, so whole network can constitute 5 grades of logical network when normal state.
In order to use the intelligent addressing function of topology network to greatest extent, take into account the processing load of network node simultaneously, each network node can write down 3 grades of nodes in top (comprising node fully) of whole logical network, and for example, the topology node is 2020200 nodes fully in the network of 10 item sign indicating numbers.
Calling procedure has made full use of 3 grades of topology that are stored in this node between node.At first, look for three grades of nodes in 3 grades of topology of node in this node internal memory near the purpose node, transmission search order from then on node obtain the more approaching senior node of purpose node, this relay inquiry for another example, finally finding the destination node address, finishing whole addressing process near the senior node of purpose node.
Renewal for nodes up to a million, keeping the much more so data in real time or the utmost point to carry out in the short time in the whole network is impossible synchronously, simultaneously also for avoiding occurring network storm, we with the scope of the real-time update of the variation of each topology network be confined to peer's circle (being connected to the circle that the node at the same level of same higher level's node is formed) of this node, directly the immediate superior of subordinate and recurrence is until the root node server, then the root node server again with the network acceptable time at interval (for example 1 second) whole network is carried out multicast.For in the network node because the problem that can not upgrade in time and cause can adopt fault-tolerant way to proofread and correct.Such as query script failure at three grades of nodes, just can know that this topology changes, then to prepare against node, inquire about with circle node, the such order of recurrence higher level, the worst result queries obtains correct addressing clue to server.Consider the complexity of network and the topological structure of the long-term online formation of node, according to probability, fault-tolerant way guarantees to be up to the correctness of the addressing under the very little situation of the probability of access server.
Consider stability of network and ease for maintenance, we are provided with node fully for each senior node, but be equipped with the topology record that node only is responsible for network, and the integrality and the correctness of assurance record itself, do not participate in the work such as addressing of network under the normal condition, when major node lost efficacy, be equipped with node and take over the maintenance that network is finished in the work of major node immediately, choose a node simultaneously from the subordinate's leaf node that satisfies the requirements and be equipped with node as it, maximum possible is avoided because node fails causes network failure.
The branch different situations are described the building process of dynamic network topology below.
Chaos state:
Please refer to shown in Figure 3ly, beginning most of network, we are referred to as chaos state.To being described as of this state: this moment, logical network did not exist, and only had or not the server of the dynamic logic topology network storage and the leaf of the no dynamic logic topology network storage physically.Require server and leaf all in same IP network this moment, and in IP layer phase mutual communication.After leaf powered up and reaches the standard grade, default setting was controlled oneself and is leaf node state, the i.e. bottom of topology network.
Please refer to shown in Figure 4ly, the dynamic network topology information whether storage is arranged is at first checked in the terminal node operation that powers on.Do not have in that yes in such cases.Terminal can obtain the address of Core server built-in when dispatching from the factory in solid-state memory, and is connected to server according to this address.After a plurality of nodes are attached to server, formed star topological structure as shown in Figure 5, server is as the center node, and all leafs are logically as the direct report node of center node.
Server is according to the number of each leaf, will be divided into same circle according to N position before each number is identical.In the layering principle that begins to mention, we can know that higher level's node nodal point number altogether that each node circle and its directly link to each other can not surpass 100, so we just exceed as the foundation of group circle with 100 according to us.Server divides the circle principle to the network classification that subordinate's node divides circle and classification to mention according to preamble.But can't do branch circle action this moment, not satisfy condition to upgrade and become non-leaf node because also there is any node now.After the two-level logic network that server, leaf node are formed built up, root node began to carry out the management function of higher level's node, and subordinate's node is detected node state according to the heartbeat agreement and collects node online hours information.Subordinate's node then with root server as higher level's logic node of controlling oneself.The node online hours reach after the default duration (supposing 24 hours or 12 hours), server is according to the node state agreement, the node of limit priority sends pre-upgrading order in the priority query that the online hours result according to the heartbeat agreement obtains, this moment, this node entered pre-upgrade status, Figure 6 shows that node upgrading flow process, upgrading is carried out according to following flow sequence:
(1) server sends pre-upgrading order to the upgrading node of choosing, and this node enters pre-upgrading attitude immediately;
(2) server common node from its higher level to the desire of choosing that adjust issues higher level's node switching command, and this node enters higher level's node and switches attitude, any addressing that takes place in this state and call out action and all send information according to last switching state original route;
(3) common node sends the request switching to the node that is in pre-upgrading attitude;
(4) upgrade node in advance after the node that will send request adds subordinate's node tabulation, send and confirm to add;
(5) its higher level's node information of change also sent the switching of affirmation higher level node after common node was received this message, and later information flow will send to new higher level's node;
(6) upgrade node in advance to the switching of server transmission affirmation appointment node, server is from the common node of direct report node deletion appointment;
(7) repeat above 2-6 and switch to pre-upgrading attitude node up to all predetermined nodes, server sends instruction, and this node rises to senior attitude from pre-upgrading attitude.
For example: suppose that number is that 1682091678 node arrives the default duration of upgrading at first, and other number node ends reach default upgrading duration, promptly rise to the one-level node of 16 field numbers this moment 1682091678, all 16 field numbers are upgraded later logic topology shown in Fig. 7 a as its child node:
Among these three grades of logical network figure, only have 1682091678 these nodes to upgrade to senior node, all the other nodes require to remain on the leaf node attitude owing to not reaching upgrading;
Suppose that after this above network physical topology directly remains unchanged, and the online hours of these all nodes of physics topology are all above default upgrading duration, and then the logic topology may become (its sorting position of priority that enters Preset Time according to each node may be slightly different) shown in Fig. 7 b:
No. 16 sections arrive predetermined order of upgrading duration and are successively: 1682081689,1682081688,1682091666,1661623089 or 1682081689,1661623089,1682081688,1682091666.The time of No. 38 section arrival is: 3882681578,3882681678.
By above-mentioned operation, in the network of initial no topology, can set up out multilevel logic system according to the number rule classification.
The node of existing network adds:
In a network that has generated, the adding of any one node all is the adition process of a leaf node, after this node is connected into logical network, can find the immediate superior node under controlling oneself according to a minute fraction circle principle.Then this node is required registration, higher level's node can immediately be connected into this node the network of controlling oneself and begin to manage work, and for preventing network oscillation, line stabilization one is preset after the on-line time on the node, this information of reaching the standard grade just can report to server step by step, changes the real-time status of this number.That is to say that node one is reached the standard grade and can be called out, but as vibrating, then influence only limits in the little network of the bottom.
The node off-line of network:
The off-line of network node should be divided into two parts: the off-line of leaf node and the off-line of non-leaf node.
The leaf node off-line:
The process comparing class that the off-line of leaf node and node are reached the standard grade seemingly, the direct-connected node of the higher level of this node is found this node off-line in the heartbeat agreement, change its presence at once and report to clothes device its off-line state step by step.
Non-leaf node off-line:
The off-line of non-leaf node is divided into three kinds of situations again:
(1) major node off-line: its immediate superior node is after detecting the major node off-line, and notice is equipped with node becomes a full member, and is equipped with node and changes its state and be main state and be broadcast to directly under node.Simultaneously, its higher level receives its acknowledge message of becoming a full member and puts alternation of hosts's message later on directly on record and give server, reports this message until server more step by step.As not being the immediate superior of leaf node, current major node is selected the highest standby node of a priority in subordinate's node, promotes to it to be equipped with node; The immediate superior of leaf node in this way, current major node is selected the highest node of a priority in subordinate's node, promote to it to be equipped with node;
(2) be equipped with the node off-line: as not being the immediate superior of leaf node, current major node is selected the highest standby node of a priority in subordinate's node, promotes to it to be equipped with node; The immediate superior of leaf node in this way, current major node is selected the highest node of a priority in subordinate's node, promote to it to be equipped with node;
(3) active and standby while off-line: the node that wherein a priority is the highest that higher level's node distributes subordinate and off-line node to enclose is together immediately taken over the work of off-line node, is called trustship in the circle; As do not have with the circle node and can take over, higher level's node or recurrence higher level finish and stride a grade trustship; Meanwhile, choose a standby node in subordinate and be upgraded to current node, and be equipped with node off-line flow process at the back space of taking over job.
Call out addressing:
Call out addressing and belong to the calling of non-memory property, the node that promptly participates in calling procedure is not done the switching of any relevant signaling, carries out continuous address lookup up to finding destination address by call source.Call source is at first searched three grades of logic node address of destination address, but might use the up mode of aforesaid recurrence to carry out the mistake of seizing of three grades of logical addresses; From three grades of logical addresses, inquire the level Four logic node of purpose afterwards; Recurrence searches and obtains destination address downwards afterwards.
The intelligence transfer:
In the IPV4 system,, thereby produced the access to netwoks scheme of NAT (network address translation) mode because address space is not enough to satisfy the demand of reality.If but communicating pair then can not be realized direct communication in different NAT networks.The node that resource capability is arranged by having from public network address to the server application is the transfer node of communicating pair, can realize the NAT network user's communication.
Please refer to shown in Figure 8, form after such topology, the addressing protocol that carries out between senior node circle by each different stage, the communication between each node can be passed through the self-service form of network, in the presence that does not have server, easily finish the foundation and the transfer of communicating by letter between node.
