3rd configuration module (not shown), for the server be assigned to according to this newly-built connection, is configured to pointer corresponding for this server in server table point to the information node corresponding to newly-built connecting structure.
In addition, the inquiry unit of this server connection state comprises further:
First removing module (not shown), for when receiving connection closed request, deletes the connection list item corresponding to connection needing to close in session table;
Second removing module (not shown), for deleting the information node corresponding to this deleted connection list item.
According to query scheme and the device of server connection state of the present invention, can realize according to the functional module shown in Fig. 3.
The present invention is directed to the demand of the session table bidirectional inquiry of application delivery equipment, devise the connection status maintaining method that one can support a large amount of server (in practice, this server can be virtual/physical server).
The inquiry unit (the application delivery equipment connection state-maintenance module such as, shown in Fig. 3) of server connection state of the present invention can preserve server by means of multiple form and be connected between corresponding relation.
These forms can be made up of three parts:
(1) Part I is session table, comprises and such as connects a, connects b, connects c, connect d and be connected the list items such as e;
(2) Part II is server list, comprises the list item of all servers 0, server 1, server 2 and server 3;
(3) Part III is orthogonal list, is made up of information node, the corresponding each connection list item of this information node and every station server.
When a new connection establishment, the inquiry unit of server connection state of the present invention (namely, connection status maintenance module in Fig. 3) not only in session table, increase a list item, and to should the server list item that distributes of connection table item and this connection, construct an information node, be inserted in orthogonal list.When a connection closed, the inquiry unit of server connection state of the present invention (namely, connection status maintenance module in Fig. 3) from session table, not only delete the list item of this connection, and according to the pointer of orthogonal list, delete the information node of this connection correspondence.The orthogonal list that information node is formed achieves associating of connection state information and server, thus can realize the bidirectional inquiry between connection status and server.
The first configuration module in the inquiry unit of above-mentioned server connection state can be used for the function realizing increasing a list item in Fig. 3 in session table; Second configuration module can construct in the orthogonal list that new information node is inserted in Fig. 3; First removing module and the second removing module to realize when connection closed the list item deleting this connection from session table that in Fig. 3, module realizes, and delete the function of information node of this connection correspondence according to the pointer of orthogonal list.
Can be applied in multiple network equipment according to the inquiry unit of the server connection state of the embodiment of the present invention, such as, can be applied to payment equipment, now, the work disposal process of this device is as follows:
One, after application delivery device start, connect state table and server table, and these two the general Hash table structures that adopt of table, to improve search efficiency, can be distributed according to configuring static or dynamically apply for.
Two, when a new connection establishment, connection status maintenance module increases a list item in session table.
Three, connection status maintenance module constructs an information node, the pointed information node of connection status list item, search in server table and connect corresponding server list item, obtain the information node chained list that this list item points to, information node is inserted the gauge outfit of chained list.
Four, when a connection closed, connection status maintenance module deletes the list item of this connection from session table, deletes before connecting list item and obtains server list item corresponding to this connection list item and information node.
Five, in server table, find the server list item that deleted connection list item is corresponding, from the information node list of server list item pointed, delete the information node that deleted connection list item is corresponding.
Six, during bidirectional inquiry, according to session table, the server that a connection status list item is corresponding can be inquired about.According to server table and orthogonal list, all connection status list items that a station server is corresponding can be inquired about.
Alternatively, when server is less, the organizational form of information node can replace orthogonal list structure with matrix structure, process one newly-built or close connection time, also can correspondingly adjust to some extent the operating sequence of data structure in the present invention.
In sum, by means of technique scheme of the present invention, the present invention is by configuration information node and represent server and the corresponding relation be connected by information node, the bidirectional inquiry of corresponding relation between can effectively realizing server and be connected, the server belonging to each connection can not only be inquired about, can also inquire the connection that each server has, the running status being convenient to application delivery equipment manages.In addition, by the function of each configuration module of the present invention, corresponding connection can be inquired exactly on the server, and when connection closed, the connection list item and corresponding information node that need to close can be deleted, save storage resources, improve search efficiency, strengthen manageability when application delivery equipment is safeguarded a large amount of server connection state.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
