There are the corresponding sessions of the message, execute step S203, if the corresponding session of the message is not present in the conversational list, hold
Row step S204；
S203 determines the member port that the corresponding session of the message includes, and the message is sent to the member
Port；
S204 determines the member port that last newly-built session is included in conversational list, by the next of the member port
Starting members port of the member port as poll；
S205 judges whether the data traffic of the starting members port is more than preset port speed constraint value, if described
The data traffic of beginning member port is not above preset port speed constraint value, step S206 is executed, if the starting members port
Data traffic be more than preset port speed constraint value, execute step S207；
The starting members port is determined as polling result by S206.
S207, the poll since next member port of the starting members port do not surpass until obtaining data traffic
The member port is determined as polling result by the member port for crossing preset port speed constraint value.
S208 is that the message distributes member port according to polling result, the message is sent to the member port；
S209 creates session in conversational list, to record the corresponding relationship of the message and assigned member port.

As shown in figure 3, three physical ports are aggregated into a logic port, two physical ports are referred to as member end
Mouth a, b and c, 5 different messages successively reach message distributor described herein, pass through message described herein point
Method of completing the square is shunted, and is that this 5 different messages distribute member port.
When receiving message 1, conversational list is inquired, respective session is not found, distributes member port a for message 1, and establish
The session of message and member port, the subsequent message for belonging to message 1 all use member port a；
When receiving message 2, conversational list is inquired, respective session is not found, since the last time is assigned with port a,
The poll since the b of port, port b does not send message at this time, therefore can distribute member port b for message 2；
When receiving message 3, conversational list is inquired, respective session is not found, since the last time is assigned with port b,
The poll since the c of port, port c does not send message at this time, therefore can distribute member port c for message 3；
When receiving message 4, there is no respective session in conversational list, according to poll principle, answers first poll port a, but this
When port a flow have reached the preset threshold of Limit Rate, therefore cannot be that it distributes port a, poll port b in order,
The flow of port b does not reach the preset threshold of Limit Rate at this time, therefore distributes port b for message 4, and new in conversational list
Build corresponding session；
When receiving message 5, there is no respective session in conversational list, according to poll principle, when last newly-built session is
