Abstract
The invention discloses an Ethernet bridge and an intelligent link method thereof. The Ethernet bridge comprises an Ethernet port, a WAN (Wide Area Network) port and an intelligent controller, wherein the intelligent controller is used for monitoring link status of the Ethernet port and the WAN port in real time, and when the link status of one port link is changed, the intelligent controller records the changes of the link status to enable the other port to immediately change the link status correspondingly. According to the invention, the defect of slow response time, which is caused by the fact that the Ethernet bridge relies on upper layer software to determine line failure, is overcome, so as to enable the line failure to be quickly known by network elements at two opposite terminals to ensure that the system can quickly switch to a backup line to guarantee the normal communication.
Description
Technical field
The present invention particularly relates to a kind of Ethernet bridge and intelligent interlinking method thereof about a kind of constructing communication network technology.
Background technology
Ethernet bridge is widely used in data communication and transmission field, is used for carrying out bridges forward between WAN port and ethernet port, can Ethernet be extended by transmission line and expand, and be a kind of constructing communication network technology commonly used.Fig. 1 is the general application schematic diagram of Ethernet bridge in the prior art.
The ethernet port of existing Ethernet bridge and WAN port are physically fully independent, behind a certain port LinkDown (link down), the another port is Link Up (link connection) still, as shown in Figure 2, like this so that the problem of circuit can not in time be found, inform, and can only find link fails by the protocol software on upper strata, and spended time is long, and the occasion higher for some requirement of real-time is not competent.
Summary of the invention
The deficiency that exists for overcoming above-mentioned prior art, main purpose of the present invention is to provide the method for a kind of Ethernet bridge and intelligent interlinking thereof, it can the Real Time Monitoring WAN port and the Link state of ethernet port, and when Link Up or Link Down occur in a certain port, immediately so that LinkUp or Link Down are also forced in the another port, thereby so that knowing circuit immediately, the opposite end network element changes, so that circuit switching.
For reaching above-mentioned and other purpose, the present invention proposes a kind of Ethernet bridge, comprise Ethernet interface and wide area network interface, this Ethernet bridge also comprises an intelligent controller, the linking status of this this Ethernet interface of intelligent controller Real Time Monitoring and this wide area network interface, when the linking status of a certain port changed, this intelligent controller was recorded linking status and is changed, and existed side by side namely so that the change of respective links state is made in the another port.
Further, this intelligent controller monitors a port generation link connection or link down change
The time, force immediately the another port that link connection or link down change also occur.
For reaching above-mentioned and other purpose, the present invention also provides a kind of intelligent interlinking method of Ethernet bridge, comprises the steps:
The linking status of each port of intelligent controller poll Ethernet bridge;
Whether the linking status of judging each port changes;
If when the linking status of front port changes, then force the another port to be changed to linking status after front port changes.
Further, do not change if work as the linking status of front port, then forcing the another port is the linking status of working as front port.
Further, change to link down if work as the linking status of front port from being in link connection, then force the another port to change to link down; If when the linking status of front port was in link connection and does not change, then forcing the another port was current link connection state.
Further, change to link connection if work as the linking status of front port from being in link down, then force the another port to change to link connection; If when the linking status of front port was in link down and does not change, then forcing the another port was current link down state.
Compared with prior art, a kind of Ethernet bridge of the present invention and intelligent interlinking method thereof are passed through at the ethernet port of Ethernet bridge inner utilization intelligent controller Real-Time Monitoring bridge and the Link state of WAN port, and when Link Up or Link Down occur in a certain port, immediately so that LinkUp or Link Down are also forced in the another port, thereby so that knowing circuit immediately, the opposite end network element changes, so that circuit switching, algorithm of the present invention simply is easy to realize, is convenient to transplant and Project Realization.
