RFC2544协议是RFC组织提出的用于评测网络互联设备的国际标准。RFC2544提供了一个对网络设备测试的基准,它规定了一系列的测试过程和发送设备,使得服务提供商和用户间可以在同一个基准下对测试的实施和结果达成共识。
随着设备容量的越来越大,这RFC2544协议的要求对设备的网络处理器(Network Processor,NP)和现场可编程门阵列(Field Programmable Gate Array,FPGA)是一个很大的挑战,往往为了能够支持发送大速率的RFC2544测试报文,需要额外增加FPGA或NP资源,或者在不增加NP资源的情况下,则需要牺牲其他功能来达到这一要求,甚至,当用户要求的RFC2544的测试速率超过链路本身的带宽时,现有技术无法通过基础测试报文测试设备,从而无法统计基础测试报文的发送和接收,从而无法确定传输是否达到用户要求。

具体实施方式
本发明实施例提供一种报文传输方法,应用于发送设备,如图1所示,该方法可以包括:
步骤101、在预设的测试时间内,向反射设备发送N0个基础测试报文。
这里,N0是大于0的整数;
步骤102、接收反射设备发送的N2个新的基础测试报文。
这里,N2小于或等于N0

这里,所述基础报文携带有回收次数,反射报文中携带的回收次数(Circular Number)定义在FRC2544所规定的吞吐率和丢包率报文格式中Sequence Number之后的填充字段中扩展4个字节,扩展后,如果配置信息中的基础测试报文长度是64字节,则没有填充字段,如图2所示,如果配 置信息中的基础测试报文长度大于64个字节,则在Circular Number之后是填充字段,如图3所示。
在本发明的其他实施例中,将N2个新的基础测试报文的回收次数减去1,得到新的回收次数;判断新的回收次数是否大于0;若存在N4个新的基础测试报文的新的回收次数大于0,则向反射设备发送这N4个新的基础测试报文。也就是说这N4个新的基础测试报文是满足预设条件的新的基础测试报文。
在本发明的其他实施例中,由于发射设备接收到的新的基础测试报文是有问题的报文,特别是其回收次数变为负数,因此,需要提出这列报文,所述将所述N2个新的基础测试报文的回收次数减去1,得到新的回收次数包括:判断N2个新的基础测试报文的回收次数是否大于0;若N3个新的基础测试报文的回收次数大于0,则将N3个新的基础测试报文的回收次数减去1,得到新的回收次数。
这样一来,在预设的测试时间内,发送设备可以往复发送基础测试报文,这样,利用了循环过程,就无需增加FPGA和NP资源,能够通过基础测试报文测试设备,因此,即使FPGA和NP资源不充足,同样可以完成测试,从而达到用户要求。
本实施例中,测试初始情况下,所述回收个数是预设的最大回收个数,当所述测试周期结束之后,所述方法还包括:统计新的基础测试报文的接收个数;根据接收个数、N0和最大回收个数,确定吞吐率和/或丢包率。
在本发明的其他实施例中,吞吐率的公式和现有技术的公式相同,本实施例就不再详述了,丢包率的丢包公式为:
Figure PCTCN2017081747-appb-000001
其中,N是接收个数,C*N0是理论上的发送个数,N0是首次的发送个数,C是最大回收次数。
由于在传输的循环过程中,发送设备每次发送基础测试报文,都能收 到新的基础测试报文,该基础测试报文和新的基础测试报文可能是相同的内容,也可能发生了一定的变化,只要不影响反射设备和发送设备识别出它是基础测试报文即可。
在本发明的其他实施例中,所述配置信息至少包括基础测试报文长度、测试速率和所述测试时间,所述根据所述配置信息确定基础测试报文包括:
根据测试速率,计算基础测试报文速率,该基础测试报文速率是所述基础测试报文或新的基础测试报文的发送速率;根据测试速率和基础测试报文速率,确定所述最大回收次数。
在本发明的其他实施例中,确定所述最大回收次数包括:
那么,最大回收次数为:C=V/V0;其中,C是最大回收次数;V是测试速率;V0是基础测试报文速率。
其中,V0的范围是(0,Vmax],Vmax为基础测试报文构造模块所能产生的最大速率。通常,为了减少报文在发射端和反射端之间循环的次数,V0从Vmax开始向下查找,找到一个最小的整数C即可。
所述方案中,如果V小于Vmax,则V0=V,C=1。
本发明实施例提供一种报文传输方法,应用于报文传输系统,该系统包括发送设备和反射设备,发送设备至少包括NP和FPGA。在测试过程中,发送设备和反射设备的报文传输过程如图4的箭头所示,报文会重复利用,且图2仅是示例性说明,如图5的流程所示,该方法可以包括:
步骤201、发送设备接收用户输入的RFC2544测试的丢包率的配置信息。
该配置信息包括配置RFC2544测试的基础测试报文的报文长度、测试速率和测试时间。
步骤202、FPGA根据配置信息确定基础测试报文。
FPGA根据配置信息的测试速率,计算出RFC2544的基础测试报文速 率,并且根据基础测试报文速率V0和测试速率V,计算反射报文最大回收次数C,所述C为:C=V/V0
其中,V0的范围是(0,Vmax],Vmax为发送设备所能产生的最大速率。
一般情况下,为了减少基础测试报文在发送设备和反射设备之间回收次数(即循环次数),V0从Vmax开始向下查找,找到一个最小的整数作为C即可。
在本发明的其他实施例中,若V小于Vmax,则V=V0,C=1。
FPGA根据V0和测试报文长度,构造基础测试报文速率为V0的RFC2544基础测试报文,并且在基础测试报文中增加回收次数,初始状态回收次数是最大回收次数。
值得说明的是,本方案中,基础测试报文模块构造基础测试报文后,需要统计基础测试报文数N0
步骤203、NP以V0的速度均匀发送N0个基础测试报文。
步骤204、反射设备处理N1个基础测试报文,得到新的基础测试报文。
这里,由于发送N0个报文,不一定就能够接收到N0个报文,因此,N1是小于或等于N0
步骤205、反射设备向发射设备发送N1个新的基础测试报文。
这里,NP接收到的新的基础测试报文个数为N2,由于发送N1个报文,不一定就能够接收到N1个报文,因此,N2是小于或等于N1
步骤206、NP判断N2个新的基础测试报文中的回收次数是否大于0。若是,则执行步骤207;若否,则执行步骤214。
这里,NP可以逐一判断N2个新的基础测试报文,可以并行同时判断几个新的基础测试报文。
步骤207、NP将N3个新的基础测试报文的回收次数减1,得到新的回收次数。
N3是回收次数大于0的新的基础测试报文的个数。
步骤208、NP判新的回收次数是否大于0。若是,则执行步骤209;若否,则执行步骤214。
步骤209、NP发送N4个新的基础测试报文。
该N4个新的基础测试报文是回收次数大于0的新的基础测试报文。
步骤210、当发送设备确定测试时间超时时,停止基础测试报文发送。
步骤211、NP在预设时长之后,停止基础测试报文接收。
这样,保证从发送设备发送出去的测试报文都反射回来,然后停止接收反射报文和统计反射报文。
步骤212、发送设备统计基础测试报文的接收个数。
步骤213、发送设备根据收个数和最大回收次数,计算丢包率。
这里,丢包率的丢包公式为:
Figure PCTCN2017081747-appb-000002
其中,N是接收个数,C*N0是理论上的发送个数,N0是首次的发送个数,C是最大回收次数。
步骤214、丢弃新的基础测试报文。
