Description
[technical field]
The present invention relates to the network trunk technology in the communication technology, particularly relate to a kind of method of main frame and PVC dynamic binding of adsl router.
[background technology]
FOR ALL WE KNOW, router is a kind of equipment that packet is carried out relaying on network.As shown in Figure 1, general A DSL router interior all has the bridge model of a multiport, and its bridge joint port comprises the Ethernet interface of Ethernet interface, PVC (PVC), radio port and USB simulation.On these bridge joint ports, message forwarding is being followed the following principle of bridges forward:
1, the source MAC (media access control address) of study message, record source MAC and source port and upgrade the timestamp of forwarding-table item in transmit;
2, utilize the target MAC (Media Access Control) address of message to search and transmit, the destination interface that the port that writes down in the corresponding forwarding-table item is transmitted as message carries out message and transmits;
Be broadcast address, just this message broadcasted to all other ports if 3 utilize target MAC (Media Access Control) address to search less than corresponding forwarding-table item or destination address;
4, a period of time (for example 1 minute) does not have the forwarding-table item of renewal, can be because overtime being deleted by the system.
Wherein, both transmitted and can organize with chained list, and also can organize with HASH (Hash table) table, and used HASH to show to organize to improve seek rate usually, and used chained list to solve the HASH collision problem simultaneously, the structural representation of list item is as follows:
struct?fib_entry
{
List_entry list; // list structure
Byte mac[6]; //MAC Address
Int port_no; // have a port index that the main frame of this MAC Address connects
Time_t time_stamp; The timestamp of // forwarding-table item
}；
According to mentioned above principle, the intercommunication mutually between each port is freely, is not subjected to any restriction.Carry out some restrictions but then need transmit message sometimes, for example, certain main frame that LAN interface inserts can only be communicated by letter with specific PVC, and perhaps its flow can only be forwarded on the PVC.Generally, adopt a kind of binding technology, by divide mode that port forms a plurality of bridges specific port binding to specific PVC.Under the situation of port binding, still there are a lot of defectives:
1, LAN/USB/VAP (Virtual Access Point the is virtual wireless access node) port that is bound to different PVC can not be visited mutually;
2, Bang Ding relation is fixed, and limits too dead;
3, binding realizes that in the port one-level All hosts under the same port is subjected to same restriction;
4, transmitting of each bridge model maintenance oneself, the waste resource.
[summary of the invention]
The present invention is intended to address the above problem, and provide a kind of online restriction of physical set that is not subjected to, All hosts under the same port can be tied to different port and each port does not disturb mutually, can save the main frame of adsl router of maintenance resources and the method for PVC dynamic binding.
For achieving the above object, the invention provides a kind of method of main frame and PVC dynamic binding of adsl router, this method comprises:
A, the dynamic binding attribute is set, makes bridge joint port, form a plurality of bridges by dividing port by specific host binding with dynamic binding attribute at the bridge joint port of adsl router, with specific port binding to specific PVC;
B, the bundling port item is set, in the forwarding-table item structure to indicate the bound port of this forwarding-table item.
Message forwarding is carried out as follows:
A, for the message that the port that never has the dynamic binding attribute receives, the application target MAC Address is searched forwarding-table item, if find forwarding-table item with target MAC (Media Access Control) address, then sends the corresponding port of message in the forwarding-table item;
If b search less than, then use source MAC to search forwarding-table item, if search less than create a new forwarding-table item; If find corresponding forwarding-table item, then upgrade the timestamp of forwarding-table item.No matter be the new list item of creating, still original list item all will be handled list item, if the bundling port in the forwarding-table item is non--1 value, then message is forwarded to bundling port; If the bundling port in the forwarding-table item is-1, then to all of the port broadcasting packet.
C, for the message that receives from port with dynamic binding attribute, the application target MAC Address is searched and is transmitted, transmit if find, upgrade bundling port in the forwarding-table item with regard to the port index that uses this port, stab update time simultaneously, then message is forwarded to the corresponding port in the forwarding-table item; Transmit if can not find, then message is transmitted to each port.
D, transmitting of not upgrading in a period of time will be deleted by the system because of overtime.
In step b, when creating forwarding-table item, an initialization list structure, MAC Address, source port and timestamp information.
Contribution of the present invention is that it efficiently solves the defective of the non-dynamic binding method of existing main frame and PVC.The present invention forms the mode of a plurality of bridges by dividing port, and specific port binding to specific PVC, thereby is had following distinguishing feature:
One, the LAN/USB/VAP port that dynamically is tied to different PVC is isolated, and does not disturb mutually;
Two, Bang Ding relation is dynamic, is not subjected to the online restriction of physical set;
Three, dynamic binding realizes that in the main frame one-level All hosts under the same port can be tied to different port;
Four, owing to do not divide VLAN, transmit, save resource so whole BRIDGE safeguards one.

[embodiment]
Consult Fig. 2, the method for the main frame of adsl router of the present invention and PVC dynamic binding comprises:
One, the bridge joint port at adsl router is provided with the dynamic binding attribute, makes the bridge joint port with dynamic binding attribute by specific host binding.As shown in Figure 2, the bridge model of adsl router is divided into a plurality of bridges (bridge), comprises four bridge bridge1～bridge4 in this example, each bridge, for example in the bridge2 with specific port, on the specific PVC2 that is tied to as Lan1, Lan2, PVC1, VAP1 etc.Like this, make that the LAN/USB/VAP port that dynamically is tied to different PVC is isolated, do not disturb mutually.
Two, the bundling port item is set in the forwarding-table item structure, to indicate the bound port of this forwarding-table item, the forwarding-table item structure that is provided with the bundling port item is as follows:
struct?fib_entry
{
List_entry list; // list structure
Byte mac[6]; //MAC Address
Int port_no; // have a port index that the main frame of this MAC Address connects
Int bind_port_no; // have a bound port index of main frame of this MAC Address
Time_t time_stamp; The timestamp of // forwarding-table item
}；
Wherein, int bind_port_no is set bundling port item.
Message forwarding to bridge joint port with bundling port is divided following two kinds of situations:
One, never has the message forwarding that the port of dynamic binding attribute receives
Two, the message forwarding that receives from port with dynamic binding attribute
A, for the message that the port that never has the dynamic binding attribute receives, the application target MAC Address is searched forwarding-table item, if find forwarding-table item with target MAC (Media Access Control) address, then sends message port_no corresponding port in the forwarding-table item;
If b search less than, then use source MAC to search forwarding-table item, if search less than create a new forwarding-table item, an initialization list structure, MAC Address, source port and timestamp information; If find corresponding forwarding-table item, then upgrade the timestamp of forwarding-table item.No matter be the new list item of creating, still original list item all will be handled list item, if the bundling port in the forwarding-table item (bind_port_no) is the value of non--1 (effective value), then message is forwarded to bundling port; If the bundling port in the forwarding-table item is-1 (illegal value), then to all of the port broadcasting packet.
D, the message that receives from port with dynamic binding attribute (being called for short the D port), the application target MAC Address is searched and is transmitted, transmit if find, upgrade bundling port (bind_port_no) in the forwarding-table item with regard to the port index that uses the D port, stab (time_stamp) update time simultaneously, then message is forwarded to the port_no corresponding port in the forwarding-table item; Transmit if can not find, then message is transmitted to each port.
E, transmitting of not upgrading in a period of time will be deleted by the system because of overtime.
By said method, the present invention has realized the main frame and the PVC dynamic binding of adsl router.It is a kind of method by source MAC forwarding realization dynamic binding, and this method is when having the user to insert, and system can if PVC is all bound, then refuses new user and insert dynamically on user binding to a PVC who inserts.If there is PVC to free out, then can dynamically insert the user again, thereby reach a kind of dynamic equilibrium, can under situation about guaranteeing service quality, improve as far as possible and insert quantity, thereby maximally utilise resource.Avoided in broadband access terminal, if LAN side user shares the bandwidth on the PVC, along with increasing of user, service quality descends unavoidably, and if the LAN side ports is tied to different PVC, then too waste problems such as resource.
