In embodiments of the present invention; When setting up into two-shipper annular pile system or monitor out current pile system when becoming two-shipper annular pile system by non-two-shipper annular pile system; Two stack ports that stack equipment comprises are bound a logic port; Make two-shipper annular pile system can't form loop, when stack equipment need send message, send neighbours' stack equipment that this message is given stack equipment through volume port of binding; Like this in two-shipper annular pile system, need not piling up at one that connects two stack equipments is provided with the choke point on the link, thereby can in two-shipper annular pile system, use the bandwidth of all piling up link.
On basis embodiment illustrated in fig. 2, the embodiment of the invention provides another kind of and in two-shipper annular pile system, has sent method of message.Wherein, set up into two-shipper annular pile system after, each stack equipment that comprises in the two-shipper annular pile system can send message to its neighbours' stack equipment by the method that present embodiment provides, referring to Fig. 3, this method comprises:
Step 201: when setting up into pile system, stack equipment is judged the pile system of setting up, and is two-shipper annular pile system if judge the pile system of establishment, execution in step 202;
Particularly; When setting up into pile system; Two stack ports that stack equipment comprises through self receive inquiry (Hello) message that neighbours' stack equipment periodically sends; And to judging through two inquiry messages of these two stack ports receptions, if two inquiry messages that receive through these two stack ports are identical, the pile system of then determining establishment is a two-shipper annular pile system.
Wherein, Stack equipment comprises two stack ports; Two stack ports that each stack equipment that after setting up into pile system, comprises in the pile system comprises through himself are periodically sent identical inquiry message and are given its neighbours' stack equipment, and two stack ports that comprise through himself receive the inquiry message that its neighbours' stack equipment periodically sends; If two inquiry messages that two stack ports that stack equipment comprises through self receive are identical; Then to determine two inquiry messages that two stack ports comprising through self receive all be the inquiry message that same neighbours' stack equipment sends to this stack equipment, and the pile system of judging establishment in view of the above comprises that the pile system of two stack equipments and establishment is the annular pile system of two-shipper.
Further, to write down current pile system be two-shipper annular pile system to stack equipment.
For example; Referring to Fig. 4; For any two stack equipments, be called first stack equipment and second stack equipment, first stack equipment comprises stack port 0 and 1; Second stack equipment comprises stack port a and b; The stack port 0 of first stack equipment is linked to each other through piling up link A with the stack port a of second stack equipment, the stack port 1 of first stack equipment is linked to each other through piling up link B with the stack port b of second stack equipment, so first stack equipment and second stack equipment are set up into two-shipper annular pile system.
Wherein, The stack port 0 of first stack equipment and the stack port a of second stack equipment be not through piling up before link links to each other; The state of the state of the stack port 0 of first stack equipment and the stack port a of second stack equipment all is down (off-line) state; When the stack port a of the stack port 0 of first stack equipment and second stack equipment through after piling up link A and linking to each other, the state of the state of the stack port 0 of first stack equipment and the stack port a of second stack equipment all becomes up (online) state from the down state; Equally; The stack port 1 of first stack equipment and the stack port b of second stack equipment be not through piling up before link links to each other; The state of the state of the stack port 1 of first stack equipment and the stack port b of second stack equipment all is the down state; When the stack port b of the stack port 1 of first stack equipment and second stack equipment through after piling up link B and linking to each other, the state of the state of the stack port 1 of first stack equipment and the stack port b of second stack equipment all becomes the up state from the down state.
Wherein, When first stack equipment and second stack equipment are set up into two-shipper annular pile system; First stack equipment can periodically send identical inquiry message through the stack port of they two up states that comprise and give i.e. second stack equipment of its neighbours' stack equipment, and first stack equipment also can receive neighbours' stack equipment through the stack port of they two up states that comprise be the inquiry message that second stack equipment periodically sends; Second stack equipment can periodically send identical inquiry message through the stack port of they two up states that comprise and give i.e. first stack equipment of its neighbours' stack equipment, and second stack equipment also can receive its neighbours' stack equipment through the stack port of they two up states that comprise be the inquiry message that first stack equipment periodically sends.
Wherein, If first stack equipment is identical through two inquiry messages that they two stack ports that comprise receive; Then can to determine two inquiry messages that two stack ports comprising through self receive be the inquiry message that same neighbours' stack equipment sends to first stack equipment, and judge current pile system in view of the above and comprise that two stack equipments and current pile system are two-shipper annular pile system; Equally; If second stack equipment is identical through two inquiry messages that they two stack ports that comprise receive; Then can to determine two inquiry messages that two stack ports comprising through self receive be the inquiry message that same neighbours' stack equipment sends to second stack equipment, and judge current pile system in view of the above and comprise that two stack equipments and current pile system are two-shipper annular pile system.
Step 202: two stack ports that stack equipment comprises self are bound a logic port;
Particularly; Stack equipment distributes a memory space; And with this memory space as logic port, the port numbers of two stack ports that self is comprised is stored in the logic port, has realized that so two stack ports that self is comprised bind a logic port.
Wherein, For two stack equipments that comprise in the two-shipper annular pile system; Two stack ports that each stack equipment comprises self are bound a logic port; Make to connect two of two stack equipments and pile up link and logically bind a logical links, so two-shipper annular pile system can't form loop on the logic aspect, avoid producing broadcast storm.
For example; For first stack equipment, the first stack equipment memory allocated space, and with the memory space that distributes as logic port C; Wherein, Stack port 0 that first stack equipment comprises and 1 port numbers are respectively the port numbers 0 of the stack port 0 that 0 and 1, the first stack equipment comprises self and the port numbers 1 of stack port 1 is stored among the logic port C, and two stack ports 0 that first stack equipment like this has been realized self is comprised and 1 are bound into a logic port C.
Equally; For second stack equipment, the second stack equipment memory allocated space, and with the memory space that distributes as logic port D; Wherein, Stack port a that second stack equipment comprises and the port numbers of b are respectively a and b, and the port numbers b of the port numbers a of the stack port a that second stack equipment comprises self and stack port b is stored among the logic port D, and two stack port a and b that second stack equipment like this has been realized self is comprised are bound into a logic port D.
Wherein, Referring to Fig. 4; First stack equipment is bound two stack ports 0 and 1 after a logic port C and second stack equipment bind a logic port D with two stack port a and b; What make to connect first stack equipment and second stack equipment piles up link A with B binds a logical links E, so makes the annular pile system of being made up of first stack equipment and second stack equipment of two-shipper on the logic aspect, can't form loop, avoids producing broadcast storm.
Step 203: stack equipment sends message through the logic port of binding and gives neighbours' stack equipment, and this message is other messages except that the inquiry message;
Particularly, stack equipment obtains the port numbers of two stack ports of storing in this logic port; From two corresponding stack ports of the port numbers of two stack ports obtaining, select a stack port, send message through the stack port of selecting and give neighbours' stack equipment.
Wherein, stack equipment can be selected a stack port according to MAC (Medium Access Control, medium access control) address or the IP address of this message from two stack ports.
For example, when first stack equipment need send message, first stack equipment obtained the port numbers 0 and 1 of the stack port of storing among the logic port C; From the stack port 1 of port numbers 0 corresponding stack port 0 and port numbers 1 correspondence, select a stack port, be assumed to be stack port 0, send this message through the stack port of selecting 0 and give neighbours' stack equipment, i.e. second stack equipment.
Equally, when second stack equipment need send message, second stack equipment obtained the port numbers a and the b of the stack port of storing among the logic port D; From the stack port b of corresponding stack port a of port numbers a and port numbers b correspondence, select a stack port, be assumed to be stack port a, send this message through the stack port a that selects and give neighbours' stack equipment, i.e. first stack equipment.
Further; For any stack equipment in the two-shipper annular pile system; The stack port that this stack equipment can comprise through himself receives the broadcasting packet that its neighbours' stack equipment sends; Confirm the logic port at the stack port place of this broadcasting packet of reception, further determine other logic ports that do not have in self except that the logic port of confirming, stop to send this broadcasting packet then and give neighbours' stack equipment; So on the logic aspect, can avoid two-shipper annular pile system to form loop, and avoid the two-shipper loop system to produce broadcast storm.
For example; The stack port that first stack equipment can comprise through himself receives the broadcasting packet of i.e. second stack equipment transmission of neighbours' stack equipment; The stack port of supposing this broadcasting packet of reception is 1; Confirm the logic port C at stack port 1 place, further determine in self not other logic ports except that logic port C, stopping to send this broadcasting packet then is second stack equipment to neighbours' stack equipment.
Equally; The stack port that second stack equipment can comprise through himself receives the broadcasting packet of i.e. first stack equipment transmission of neighbours' stack equipment; The stack port of supposing this broadcasting packet of reception is a; Confirm the logic port D at stack port a place, further determine in self not other logic ports except that logic port D, stopping to send this broadcasting packet then is first stack equipment to neighbours' stack equipment.
Wherein, Need to prove: after setting up into two-shipper annular pile system; Two stack ports that any stack equipment in the two-shipper annular pile system all periodically comprises through himself are sent the inquiry message and are given its neighbours' stack equipment, and two stack ports that comprise through self receive the inquiry message that its neighbours' stack equipment periodically sends.
Wherein, Need to prove: after setting up into two-shipper annular pile system; Any stack equipment in the two-shipper annular pile system, the current pile system that this stack equipment has write down according to self are that two-shipper annular pile system carries out real-time listening to current pile system.
Particularly; Two stack ports that this stack equipment comprises through himself receive the inquiry message that its neighbours' stack equipment periodically sends; Two inquiry messages to receiving through these two stack ports are judged; If both current pile systems identical and that write down are two-shipper annular pile system; Then monitoring out current pile system still is two-shipper annular pile system, if both current pile systems different and that write down are two-shipper annular pile system, then monitor out current pile system and becomes non-two-shipper annular pile system by two-shipper annular pile system.
Further, become non-two-shipper annular pile system if monitor out current pile system by two-shipper annular pile system, then this stack equipment current pile system that self has been write down is updated to non-two-shipper annular pile system.
Wherein, if pile system became non-two-shipper annular pile system by two-shipper annular pile system before any stack equipment in the two-shipper annular pile system was monitored out, then carry out following steps 204.
Step 204: stack equipment is when monitoring out current pile system and become non-two-shipper loop system by two-shipper annular pile system, and stack equipment is separated binding to recover two stack ports that are bundled on this logic port to logic port.
Particularly; Stack equipment is when monitoring out current pile system and become non-two-shipper loop system by two-shipper annular pile system; Discharge the memory space that the logic port that self comprises takies, so realize logic port is separated binding to recover two stack ports that are bundled on this logic port.
For example; First stack equipment is when monitoring out current pile system and become non-two-shipper loop system by two-shipper annular pile system; Discharge the memory space that the logic port C that self comprises takies, so realize logic port C is separated binding to recover two stack ports 0 and 1 that are bundled on the logic port C; Equally; Second stack equipment is when monitoring out current pile system and become non-two-shipper loop system by two-shipper annular pile system; Discharge the memory space that the logic port D that self comprises takies, so realize logic port D is separated binding to recover two stack port a and the b that is bundled on the logic port D.
Wherein, Need to prove: after current pile system becomes non-two-shipper loop system by two-shipper annular pile system; Any stack equipment in the pile system; Two stack ports that this stack equipment periodically comprises through himself are sent the inquiry message and are given its neighbours' stack equipment, and two stack ports that comprise through self receive the inquiry message that its neighbours' stack equipment periodically sends.
Wherein, Need to prove: after current pile system becomes non-two-shipper loop system by two-shipper annular pile system; Any stack equipment in the non-two-shipper annular pile system, the current pile system that this stack equipment has write down according to self are that non-two-shipper annular pile system carries out real-time listening to current pile system.
Particularly; Two stack ports that this stack equipment comprises through himself receive the inquiry message that its neighbours' stack equipment periodically sends; Two inquiry messages to receiving through these two stack ports are judged; If both current pile systems different and that write down are non-two-shipper annular pile system; Then monitoring out current pile system still is non-two-shipper annular pile system, if both current pile systems identical and that write down are non-two-shipper annular pile system, pile system becomes two-shipper annular pile system by non-two-shipper annular pile system before then monitoring out.
Further, if pile system becomes two-shipper annular pile system by non-two-shipper annular pile system before monitoring out, then this stack equipment current pile system that self has been write down is updated to two-shipper annular pile system.
Wherein, if pile system became two-shipper annular pile system by non-two-shipper annular pile system before any stack equipment in the two-shipper annular pile system was monitored out, then return step 202 and begin to carry out.
