Embodiment
Below in conjunction with drawings and Examples summary of the invention of the present invention is further described.
The invention provides a kind of method that integrated marked network inserts switch router mapping performance of weighing, the mapping performance index that insert switch router have been defined, comprise that address pool heap(ed) capacity, mapping rate, mapping postpone, maximum mapping speed, and method of testing at above-mentioned performance index proposed, provide a kind of feasible scheme for weighing the mapping performance that integrated marked network inserts switch router.
Performance index of the present invention are defined as follows:
Address pool heap(ed) capacity: the number of the Route Distinguisher of the maximum that to be the Route Distinguisher address pool that refers to an access switch router can hold under the situation of packet loss not.Each access switch router is all preserved and has been safeguarded a Route Distinguisher address pool, is used to the access sign that accesses terminal to distribute the Route Distinguisher of mutual mapping with it, and the address pool heap(ed) capacity of the access switch router of different hardware configurations is different.The access sign quantity of the equipment of access has surpassed its address pool heap(ed) capacity if the access switch router needs simultaneously, will cause identifying for the access that exceeds part distributing Route Distinguisher, causes and can't insert.Therefore, the address pool heap(ed) capacity of access switch router has determined it can support the maximum terminal quantity that inserts.In when test, the address pool maximum capacity is big more, shows that the number of access terminals that tested access switch router institute can support is many more, and is strong more to the ability that inserts support.
Mapping rate: be meant that the entry number that the access switch router can successfully be shone upon accounts for the percentage of answering the map entry number when access sign quantity reaches the capacity in pond, current address under certain Bao Changyi fixed load.The mapping rate reflects that mainly inserting switch router separates the performance of shining upon under the running at full capacity situation, and the mapping rate can be weighed and insert switch router is finished the separation mapping under steady load success rate.When test, reflect radiance rate value more near 100%, show that tested access switch router is high more to the mapping disposal ability under this flow load.The computational methods of mapping rate are: the access sign quantity that success is shone upon is divided by Route Distinguisher capacity in the address pool, as the formula (1).
That is,
Mapping postpones: be to refer to an access switch router shared time of mapping process under certain Bao Changyi fixed load.The reason that mapping postpones generation has two: the one, and the sequence of operations of finishing during mapping expends certain hour as inquiry opposite end mapping table, inquiry sign mapping server, separation mapping etc.; The 2nd, the packet delay that queuing produces in the buffer queue that separates mapping.Mapping postpones to be used for weighing access switch router handle packet and finishes mapping speed, and the mapping length of delay is more little, and it is fast more to show that tested access switch router is handled mapping speed.The computational methods that mapping postpones are: insert the switch router bulk delay and deduct the storage forward delay, as the formula (2).
Mapping delay=bulk delay-storage forward delay (2)
Wherein, insert the switch router bulk delay and be meant that first bit of packet enters the access interface that inserts switch router leaves the routed port that inserts switch router to a last bit time; The storage forward delay is meant to shine upon and finishes after insert the time that the routed port of switch router forwards packet.
Maximum mapping speed: be that the mapping rate that refers to an access switch router is 100% o'clock, can finish the maximum quantity of mapping (enum) data bag in the long following unit interval at certain bag.The unit of measurement of maximum mapping speed is a per second mapped data bag number.Maximum mapping speed is used to weigh and inserts the switch router unit interval and finish the maximum of map amount, be to describe one of basic parameter that inserts switch router performance quality, maximum mapping rate value is big more, shows that tested access switch router per second under test pack is long is can the mapped data amount big more.An access switch router may provide a plurality of access interface and routed port, and maximum mapping speed is divided into following two kinds according to test granularity difference:
1, the maximum mapping of complete machine speed
The maximum mapping of complete machine speed is to refer to an access switch router complete machine mapping ability.Usually the maximum mapping of complete machine speed is less than the summation of the maximum mapping of all of the port speed.
2, the maximum mapping of port speed
The maximum mapping of port speed is to refer to an access the mapping ability of certain access interface of switch router to certain routed port, and these two ports are phase same rate port usually.The maximum mapping of port speed is relevant with the position and the relation between port at port place.
The present invention is a kind of to weigh the method that integrated marked network inserts switch router mapping performance, comprises pond, test address heap(ed) capacity, and measure that mapping rate, mapping postpone, one or more in the several performance index of maximum mapping speed.

According to the mapping relations configuration of second port of test instrumentation, set the opposite end mapping table of tested access switch router;
Set up whole Route Distinguisher and the mapping relations that insert sign in the address pool that inserts switch router;
First port of test instrumentation sends the test data stream that has timestamp to the access interface that inserts switch router;
Calculate and insert the time interval that the switch router transmitting time is stabbed and time of reception stabs, obtain inserting the bulk delay of switch router;
Configuration inserts switch router, will all insert sign and be configured to not have mapping status;
The port of test instrumentation sends the test data stream that has timestamp to the access interface that inserts switch router;
Calculate and insert the time interval that the switch router transmitting time is stabbed and time of reception stabs, obtain inserting the storage forward delay of switch router;
Calculate the bulk delay that inserts switch router and store the poor of forward delay, obtain inserting the mapping of switch router under this bag is long and postpone.
9. method according to claim 4 is characterized in that, the maximum mapping of test speed may further comprise the steps:
Configuration inserts switch router address pool capacity, and the address pool capacity is smaller or equal to described address pool heap(ed) capacity;
First port of test instrumentation connects the access interface that inserts switch router;
The main frame that first port simulation of test instrumentation is identical with Route Distinguisher quantity in the address pool that inserts switch router with different access signs;
Second port of test instrumentation connects the routed port that inserts switch router;
Routed port that inserts switch router of second port simulation of test instrumentation, this port has the Route Distinguisher different with tested access switch router;
According to the mapping relations configuration of second port of test instrumentation, set the opposite end mapping table of tested access switch router;
Set up whole Route Distinguisher and the mapping relations that insert sign in the address pool that inserts switch router.
First port of test instrumentation sends the test data stream of specifying bag long to the access interface that inserts switch router;
Insert switch router and check whether test data stream has packet loss, if packet loss, changing down occur; If packet loss do not occur, advance the speed;
Repeat to send test data stream and judge whether the step of packet loss, obtain inserting the test data flow rate of the maximum of switch router under the situation of packet loss not, this test data flow rate shines upon speed for this bag maximum under long.
