Embodiment
The thought that the present invention adopts the communication modes that point mode is mixed use with the IP multicast based on the remote virtual environment construction method of gateway and binding site to reach utilization " multicast " on wide area network is filtered, reduce the goal of the invention of volume of transmitted data on the network, be beneficial to the maintenance and expansion of system, be applicable to large-scale distributed system.
1, structure is based on the remote virtual environment of gateway
Gateway of adding in each local area network (LAN) of virtual environment passes through the gateway mutual communication between each local area network (LAN).As shown in Figure 1, Simulation Application node in the local area network (LAN) all will by the gateway of this local area network (LAN) finish with wide area network on the data communication of Simulation Application node, angle from the Simulation Application node, gateway in the local area network (LAN) has just replaced all the Simulation Application information in the wide area network, and the network condition on the wide area network and the deployment of Simulation Application are transparent for the Simulation Application node in the local area network (LAN).
Adopt point-to-point mode to carry out communication on the wide area network between the gateway, each gateway has been represented the artificial intelligence of own place local area network (LAN), and adopt reliable TCP to connect the interactive simulation data between these gateways, can effectively avoid on wide area network, being provided with the single-point bottleneck problem that central server brings.And adopt the IP multicast mode to carry out communication between the gateway of the Simulation Application node in the same local area network (LAN) and this local area network (LAN).Gateway is identical with communication interface between the Simulation Application, and the Simulation Application node does not need to change because of the adding of gateway.
Remote virtual environment based on gateway is the basis of realizing towards the multicast spreading method of wide area network remote virtual environment, gateway becomes the entity of the point-to-point mode of intelligence transmission between wide area network, and can guarantee the multicast communication mode in the local area network (LAN), each local area network (LAN) can also multiplexing same multicast address and do not interfere with each other simultaneously.
2, unit grid is divided
In the data filtering method based on the zone, adopt the notion of path spacing (Routing SpaCe) usually.Path spacing is an abstract multidimensional coordinate system, and simulated members uses this coordinate system to describe the type and the condition of the data that can send and wish to receive.The subclass of path spacing is called zone (Region), and the member states the data that it will send by upgrading zone (Update Region), states the data that it will receive by ordering zone (SubsCripetion Region).By upgrading the zone and ordering regional coupling and calculate, set up corresponding relation between data receiver and the recipient, and by this generation and the route that concerns guide data.
This method efficient when simulation scale is smaller is higher, when simulation scale is bigger, if having changed, member upgrades the zone, need to find out all and the regional crossing subscriber of this renewals so, and whether recomputate and intersect, the cost that is spent is insupportable.
The present invention adopts a kind of simple relatively matching scheme, can be under situation about guaranteeing at large scale emulation, and the cost of coupling can be too not high.At first virtual environment is divided into the unit grid of fixed size, gateway is that each unit grid in the local area network (LAN) distributes multicast address and a grid identification number ID, and preserves its corresponding relation, and virtual environment is divided into 25 unit grids as shown in Figure 3, and gateway is C
11Unit grid distributes multicast address A
11, be C
23Unit grid distributes multicast address A
23So, multicast group that each unit grid is just corresponding.Gateway adds all multicast group, is used for obtaining the state updating information of simulated members.The division of the unit grid in each local area network (LAN), distribution was just finished in the distribution of multicast address, and the grid cell preserved of gateway and the corresponding relation of multicast address all belong to static data before emulation begins.
3, Qu Yu mapping
The renewal zone of all simulated members in the virtual environment and order zone all are mapped as the set of unit grid, mapping method is: if some belongs to certain renewal zone or orders the zone in certain grid, just this grid is joined in the grid set that this renewal is regional or the order zone is corresponding.
Path spacing with two dimension is that the present invention is further illustrated for example as shown in Figure 3: suppose certain time point an analogue system, the distribution situation in the dividing condition of grid cell and the renewal of simulated members, order zone as shown in Figure 2.U wherein

55The expression unit grid, the correspondence sign of grid is positioned at the center of each grid.
The situation that each zone is mapped to the grid cell set is:

Each simulated members need add the order area relative multicast group of oneself, need be incorporated as unit grid S as simulated members f1
F1={ C

24Pairing multicast group, simulated members f2 need be incorporated as unit grid S
F2={ C
14, C
15, C
24, C
25Pairing multicast group.Each simulated members is issued its more new data by upgrading the area relative multicast group, obtains its ordered information by ordering the area relative multicast group.
4, the order zone of local area network (LAN)
Gateway need safeguard that is ordered member's set for each unit grid of own place local area network (LAN), if certain unit grid belongs to the set of the order area relative unit grid of a simulated members, then this simulated members is joined in order member's set of this unit grid;
The order zone of gateway place local area network (LAN) is exactly to order member set not to be the set of empty unit grid.Constantly, the order member of each grid correspondence gathers as follows in the simulated environment as shown in Figure 3:
C
11＝{}
C
12＝{}
C
13＝{f1}
C
14＝{f1，f2}
C
15＝{f2}
C
33＝{f4}
C
34＝{f3，f4}
C
55＝{}
The order zone of gateway is exactly to order the member not to be the set of empty unit grid: U
G={ C
13, C
14, C
15, C
23, C
24, C
25, C
32, C
33, C
34, C
35, C
42, C
43, C
44, C
45.The order zone of while gateway also equals interior all members of its place local area network (LAN) and orders the union in zone, promptly is U in Fig. 2
G=S
F1∪ S
F2∪ S
F3∪ S
F4
Unit grid is static for gateway, be ready-portioned in advance before emulation, it is to be relatively easy to that order member by unit grid gathers the order zone that obtains gateway, and the order zone of gateway is exactly to order the member not to be the set of empty unit grid.And if obtain the order zone of gateway by the union in the order zone of all simulated members in the local area network (LAN) of gateway place, the consumption rate of calculating is bigger.
When a simulated members enlarges its order zone or increases the order zone of a simulated members newly in the local area network (LAN), gateway directly increases this simulated members in order member's set of the unit grid of correspondence, if the order member of grid cell set was empty originally, then upgrades this grid cell and join in the gateway order zone.For example among Fig. 3, simulated members f1 enlarges its order region S
F1={ C
12, C
13, C
14, C
22, C
23, C
24, gateway is at C
12And C
22Increase simulated members f1 in the order set of grid cell correspondence, because C
12And C
22Order member's set of grid cell was empty originally, so increase these two grid cells in the order zone of gateway, obtained U
G={ C

The order zone or simulated members when logging off of dwindling it when simulated members in the local area network (LAN), gateway need be from order member's set of the grid cell of correspondence this simulated members of deletion, if the order member of grid cell set becomes sky, then more new gateway is ordered the zone, with this grid cell deletion.For example among Fig. 3, simulated members f2 logs off, its order region S
F2={ C
14, C
15, C
24, C
25, gateway will be at C

5, transfer of data between gateway
In framework, be the connected mode that adopts equity between each gateway, and their adopt to connect reliably and send data based on the remote virtual environment of gateway.The transfer process figure of data as shown in Figure 4 and Figure 5 between gateway.
Fig. 4 is a gateway data forwarding flow chart of the present invention, after gateway is received the state updating information of simulated members in certain multicast group, to mate according to the order zone of each gateway of being preserved in the list of gateways of being preserved, if the unit grid of this multicast group correspondence is in the order zone of certain gateway, then this state updating information is sent to this gateway, do not filter this information; If in the order zone of gateway, then do not filter this information.
The purpose gateway that source gateway obtains after the match is successful sends two a tuples＜grid ID, data message 〉, wherein grid ID is the unit grid sign of the source gateway multicast group correspondence of receiving this information, and data message is the state updating information of the simulated members transmitted.
Fig. 5 is a gateway Data Receiving flow chart of the present invention, receives that other gateways are sent two tuples＜grid ID, data message on the wide area network〉after, gateway finds the multicast address of this grid ID correspondence according to the grid ID that oneself preserves and the corresponding relation of multicast address.Gateway is from two tuples＜grid ID, data message〉in restore the state updating information of simulated members after, be forwarded to again in the corresponding multicast address, finish the multicast transmission on the wide area network.
Describe in detail with an analogue system as shown in Figure 6 below, have 4 local area network (LAN)s and finish simulation work jointly, the order zone of each gateway is a dash area.When the order zone of gateway 1 changes, when perhaps connecting success with new gateway, all can be with own up-to-date order zone U
G1Information sends to associated gateway, has also received from gateway 2,3 that the information in 4 up-to-date order zone in the list of gateways of gateway 1, will be preserved their order area information U for each gateway that has connected simultaneously
G2, U
G3, U
G4
When gateway 1 is received Data Update information from certain multicast group, as from grid cell C
32The information of corresponding multicast group is at first inquired about the order area information of each gateway in the list of gateways, finds grid cell C
32In the order zone of gateway 2 and gateway 4, and not in the order zone of gateway 3.So this information belongs to redundant information for the local area network (LAN) at gateway 3 places, belong to effective information for the local area network (LAN) at gateway 2 and gateway 4 places.Gateway 1 will send two a tuples＜C
42, data message〉and send to gateway 2 and gateway 4, gateway 2 and gateway 4 are at first searched the grid cell of oneself and the mapping table of multicast address after having received this two tuple, find in the local area network (LAN) of own place grid cell C
42Pairing multicast address is A
42, again the data message in two tuples is sent in this multicast group, thereby finishes the multicast transmission of data in wide area network.
