Two pieces of physical network cards are invented one piece of Microsoft Loopback Adapter, to realize HSR node by the relevant interface of middle NDIS network-driven
LRE function is used for and external HSR network communication.On this basis, pass through the packet filtering side of NDIS driving interface by changing
Formula controls the sending logic of Microsoft Loopback Adapter LRE, realizes the normal and abnormal logic test of HSR network.
Under normal circumstances, after the physical network card of driver binding receives message, the HSR label of message is taken out, according to mark
Serial number SeqNum, AB network mark in label knows the source MAC of LanID and frame head, determines this frame message according to discard algorithm
Whether continue to be transmitted to another network interface card, decides whether to be given to Microsoft Loopback Adapter upper-layer protocol stack and application upwards.Upper layer application issues
To the message of Microsoft Loopback Adapter, Microsoft Loopback Adapter is first copied into 2 parts, and fills HSR label respectively, fills out current SeqNum etc.
Label information is transmitted to equipment under test by the bottom physical network card of driving binding respectively.
Before the exception handling logic of test equipment, NDIS is driven and is arranged by driving application interface by test control program
At various different packet filtering modes, carry out frame repetition respectively, frame losing, frame are distorted, postpone, is out-of-order, etc. various Message processings patrol
Collect test.
When test frame reprocesses logic, after application layer message reaches Microsoft Loopback Adapter protocol layer increase HSR label, it is forwarded to
Before bottom A, B net, driving randomly selects A net or B network data, a identical message is replicated, and together with original message, by right
It answers network interface card to be sent to equipment under test, whether normal watches the work of equipment under test network
When testing frame losing processing logic, after application layer message reaches Microsoft Loopback Adapter protocol layer increase HSR label, bottom is forwarded
To A, B net, random drop A net or B network data are no longer forwarded to corresponding network interface card, whether watch the work of equipment under test network
Normally
When test frame distorts logic, after application layer message reaches Microsoft Loopback Adapter protocol layer increase HSR label, it is forwarded to A, B
Before net, the message that A net or B are netted changes certain field datas at random, is sent to equipment under test, watches equipment under test network work
Whether normal make
When test frame delay logic, packet buffer queue is respectively set in A, B net, and starts timer.Application layer message arrives
After increasing HSR label up to Microsoft Loopback Adapter protocol layer, before being forwarded to A, B net, it is directly stored in buffer queue and does not send immediately.Fixed
When device timed task in, analyze the message of buffer queue, the message for reaching the delay time limit passed sequentially through bottom network interface card and is sent to
Whether normal equipment under test watches the work of equipment under test network.
When test frame random ordering logic, packet buffer queue is respectively set in A, B net, and starts timer.Application layer message arrives
After increasing HSR label up to Microsoft Loopback Adapter protocol layer, before being forwarded to A, B net, it is directly stored in buffer queue and does not send immediately.Fixed
When device timed task in, analyze the message of buffer queue, the message of buffer area resequenced, and is sent to by bottom network interface card
Whether normal equipment under test watches the work of equipment under test network
The beneficial effects of the present invention are: realizing the LRE of HSR agreement by the NDIS driving of system, link layer is directly handled
Message realizes that redundancy sends and receives and abandons processing.By changing on practical transmission A, B network of LRE when testing abnormal logic
Message content realizes that various exception messages are sent to equipment under test, reaches test purpose.Test macro and method energy of the invention

It manages the relevant upper-layer protocol of empty network interface card and requests NDIS_MINIPORT_DRIVER_CHARACTERISTICS, another set of processing binding
Lower layer's physical network card requests NDIS_PROTOCOL_DRIVER_CHARACTERISTICS.Pass through letter after initialization callback collection of functions
Number NdisRegisterProtocolDriver driving is tied on predetermined 2 pieces of physical network cards (A, B network interface card).Lead to simultaneously
Cross NdisMRegisterMiniportDriver function initialization of virtual network interface card, Microsoft Loopback Adapter relevant information be set, as network speed,
MTU etc..Two buffer queues are set simultaneously, are respectively used to the interim storage of A net and B network packet when the test of frame random ordering.Pass through
NdisSetTimerObject initializes a timer, the transmission for two buffer queue messages.One random data is set simultaneously
Generator can produce including 4 kinds of 0,1,2 and 3 states immediately, respectively represent this processing without exception, A net exception
Reason, B net abnormality processing, AB net equal abnormality processing.
Receive message: Fig. 6 is that a kind of HSR equipment provided in an embodiment of the present invention receives message flow diagram, such as Fig. 6 institute
Show, after message that physical network card receives reaches driving, message NBL is linearized to delaying by function GetNetBufferData first
Rush area, obtain HSR label data from buffer area, after judging HSR label really and being HSR frame, taken out from label serial number SeqNum,
AB network mark knows the source MAC of LanID and frame head.Global node table, which is searched, by source MAC adds new node if not finding
NODE_DAT is to node table.Then function is abandoned according to SeqNum, LanID calling and judges whether this frame message had received.
If this frame message received, directly forwarded by another network interface card.If this frame message does not receive, first passes through another network interface card and turn
It sends out, while HSR label is then removed by function StripNBL function on the basis of former message data and constructs new message frame,
