Abstract
The invention discloses a network bridge with a function of error code testing. The network bridge comprises an MPU (microprocessor unit), an Ethernet port and a port E1. A signal detector and a flow detector are connected between the MPU and the Ethernet port. An error code tester is further connected between the MPU and the port E1. The network bridge has the advantages that the bridge has the function of error code testing and can monitor channel error codes and monitor channel signal quality and data flow, and accordingly damage or loss of data packets and jamming of data are avoided.
Description
Technical field
The present invention relates to a kind of bridge, relate in particular a kind of bridge with the error code testing function.
Background technology
Bridge is called again network bridge.The function of bridge is similar to repeater in the prolongation network span.Bridge gets up two similar network connections, and the circulation of network data is managed.Data link layer is made in its work, distance or scope that not only can extended network, and performance, reliability and the fail safe that can improve network.Because the segmentation of network, each network segment is relatively independent, and the fault of a network segment can not have influence on the operation of another network segment.But existing bridge is the bridge joint at the pure relay type of link layer, can't make evaluation process to signal quality and the data traffic at passage two ends, often causes passage congested, and packet loss is serious, or even network equipment large tracts of land is blocked situation about crashing.This will bring very serious threat to the network user's data, and especially those are transmitted the very high network data of data reliability requirement and used, as based on H.320 the network teleconference.
Summary of the invention
The invention provides a kind of bridge with the error code testing function, it has the error code testing function, can monitor the error condition of passage, and signal quality and the data traffic of passage are monitored, and avoids the obstruction of data rascal or packet loss and data.
For solving above-mentioned technical problem, the present invention by the following technical solutions:
Bridge with the error code testing function, it comprises microprocessor MPU, ethernet port and e1 port, be connected with signal detector and flow detector between described microprocessor MPU and the ethernet port, also be connected with code error tester between described microprocessor MPU and the e1 port.
Further technical scheme is:
Be connected with control panel on the described microprocessor MPU, described control panel is provided with display unit and test control button.
Also be connected with error code display unit and network management interface on the described microprocessor MPU.
Described error code display unit is the LED lamp, and described LED lamp is arranged on the control panel.
Described code error tester is SM-PRBS-7, is made of the CPLD circuit.
Described signal detector is SM-XBR2.0.
Described flow detector is XT5600.
Described microprocessor MPU is MCIMX27VOP4A.
Compared with prior art, the invention has the beneficial effects as follows:
1, the present invention is with error code testing device, and it can be tested the signal quality of E1 passage, and error condition and result monitor and show.
2, be connected with signal detector between ethernet port of the present invention and the microprocessor MPU, can monitor ethernet port packet classification and integrality, avoid a large amount of rascals of data, packet loss.
3, be connected with flow detector between ethernet port of the present invention and the microprocessor MPU, can monitor packet classification and the congestion situation of ethernet port, avoid port data congested and crash.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Fig. 1 is structured flowchart of the present invention.
Embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.Embodiments of the present invention include but not limited to the following example.
[embodiment]
The bridge with the error code testing function as shown in Figure 1, it comprises microprocessor MPU, ethernet port and e1 port, be connected with signal detector and flow detector between described microprocessor MPU and the ethernet port, also be connected with code error tester between described microprocessor MPU and the e1 port.
Be connected with control panel on the described microprocessor MPU, described control panel is provided with display unit and test control button.
Also be connected with error code display unit and network management interface on the described microprocessor MPU.
Described error code display unit is the LED lamp, and described LED lamp is arranged on the control panel.
Described code error tester is SM-PRBS-7, is made of the CPLD circuit.
Described signal detector is SM-XBR2.0.
Described flow detector is XT5600.
Described microprocessor MPU is MCIMX27VOP4A.
Device for detecting code error of the present invention is made of the CPLD chip, and the internal digital logical circuit is revised and sintering by programmable device.Code error tester can carry out error code testing to the data of e1 port, when having monitored error code, and the error code display unit, namely the LED lamp is lighted by microprocessor MPU control.Signal detector is monitored the packet of ethernet port, and when the communication quality of ethernet port was poor, microprocessor MPU was then controlled and reduced the requirement that bandwidth chahnel satisfies signal quality and avoid a large amount of rascals of data or packet loss.Flow detector is monitored the data congestion situation of ethernet port, and when ethernet port was congested, microprocessor MPU sent the PAUSE halt signal to network-termination device, avoids causing the congested of port or deadlock.Control panel is used for the manually whole bridge equipment of control.
Be as mentioned above embodiments of the invention.The present invention is not limited to above-mentioned execution mode, and anyone should learn the structural change of making under enlightenment of the present invention, and every have identical or close technical scheme with the present invention, all falls within protection scope of the present invention.
