Account for successfully, this entity just becomes the main body sending and receiving message, other entities all carry out message transmission with this entity.This
The all of entity of sample all can be shared this linkup transmit and receive message.Specifically, comprise the steps：
The first step：Preempting resources identifier
As shown in figure 11, in the case of normal flow, the entity being used for perform script program in each browser can start
One task, this task is used for attempting preempting resources identifier, using LocalConnection.connect (resource identification
Symbol).Because identical resource identifier only has an entity can occupy, thus necessarily occur that only one of which entity accounts for
There are resource identifier, referred to as principal, and other entity then can not occupy, referred to as from entity；Under abnormal flow process, in order to
Can be fault-tolerant, prevent principal exception or be closed by the user, can continuously attempt to occupy resource identification with certain frequency from entity
Symbol, once principal occurs extremely, then having one can occupy the principal that resource identifier becomes new from entity again.
Second step：Add multicast group

Message multicast to all of entity.Idiographic flow is as follows：
For principal：1) first judge whether to have added multicast group：If first switching on entity, then not addition group
Broadcasting group, if becoming principal by from entity competition, then adding multicast group, if not adding multicast group, needing to add.
2) judge to whether there is multicast group name in ShareObject：First switch on entity or ShareObject deleted by user,
Then do not exist, other situations all exist.If it does not exist, then needing to create uniquely identified multicast group name and write
ShareObject, if it is present directly utilizing multicast group name to add multicast group, wherein it is preferred that adding multicast group to need
To use GroupSpecifier class and the NetGroup class of flash.
For from entity：1) that newly opens does not all add multicast group from entity, and direct requirement adds.2) judge
Whether there is multicast group name in ShareObject：Normal condition exists certainly, is created using multicast group name and adds same
Individual multicast group；If there is no (as ShareObject is deleted by user), then enter abnormal flow process.3) abnormal flow process：Call master
The method of the acquisition multicast group name that the LocalConnection of entity provides, takes the write of multicast group name
ShareObject, and add same multicast group.
Wherein, unique multicast group name is in order to the other machines in the same network segment do not interfere with each other, and needs every
Machine generates unique title it is preferred that the scheme using random 32 character strings can be taken.
3rd step：Message transmission
As shown in figure 13, each sends from the message of entity and calls LocalConnection.send (resource identifier, side
Religious name, parameter), the transmission message approach being provided by principal sends message.Safeguard in the method and be connected with the length of server.
When there being message to be sent to principal, principal can be disappeared from entity multicast to all of by the multicast group creating before
Breath.All of all can obtain, from entity, the message receiving, then filter to take to obtain one's own message.
Since it is desired that identifying the whether one's own entity of this message, each entity is needed to have a unique mark, excellent
Choosing, can be completed by generating 32 character strings at random, so whole message body needs a kind of data structure supporting.For
The message transmission of P2P, the agreement of itself has necessarily contained sender and the recipient of message, so substantially not needing extra
Definition；For the message transmission of BS structure, need user oneself in server end and the identification of the client side of being transmitted.Preferably
, can be as shown in the table.So far, the flow process sending and receiving message all completes, and all of entity and server
Connect and only exist portion.
