Description

互联设备预加重配置方法、装置、系统及网络设备 Pre-emphasis network device configuration method, apparatus, system and network equipment

技术领域 FIELD

[0001] 本发明涉及网络通信技术领域,尤其涉及一种互联设备预加重配置方法、装置、系统及网络设备。 [0001] The present invention relates to network communication technologies, and in particular, to a pre-emphasis network device configuration method, apparatus, system and network equipment.

背景技术 Background technique

[0002] 互联端口指的是两台网络设备上的两个端口通过物理传输介质(例如铜缆模块或者光模块)连接的情况,如图1所示,设备1上的端口A和设备2上的端口B通过物理传输介质连接,从端口A发出的报文通过物理传输介质直接到达端口B,反之亦然。 [0002] interconnecting the two port means a physical port via a transmission medium (e.g. copper or optical module Module) connected to the case, as shown on the port A and the apparatus 1, the apparatus 12 on the two network devices port B is connected via a physical transmission medium, packets sent from port a reaches the port B directly through the physical transmission media and vice versa. 通过互联端口连接的两台网络设备可以称为互联设备。 Two network devices connected to a port may be referred to through the Internet connected devices.

[0003] 现有的接入和汇聚交换机设备等都带有光口,为了实现交换机设备的短距离互联,同时节约成本,通常选择铜缆模块互联,尤其是数据中心的虚拟交换机设备的应用环境中。 [0003] Existing access and aggregation switch device having a light port and so, in order to achieve short-range network switching equipment, cost savings, generally selected copper interconnect module, in particular the application environment of the virtual data center switch device in. 由于不同型号的交换机设备铜缆模块互联的指标差异较大,大部分交换机设备只能支持3米的铜缆模块互联,少部分可以支持5M的铜缆模块互联。 Due to differences in indicators of different types of switching equipment copper interconnect module is large, most of the switch device can only support copper interconnect module 3 meters, can support a small part of 5M copper interconnect module. 如果需要支持7M甚至更长铜缆模块互联,需要增加PHY芯片进行增强驱动。 If you need even more support 7M copper interconnect module, we need to increase the PHY chip enhanced driver.

[0004] 影响通信误码率(BER,Bit Error Rate)的首要因素是信号传输质量,包括幅度、 噪音等。 [0004] The primary factor affecting the communication error rate (BER, Bit Error Rate) is the signal transmission quality, including amplitude noise. 铜缆模块因为信号衰减较大,不同长度、规格的铜缆模块,衰减程度存在差异。 Since a large signal attenuation, of different lengths, module specifications copper, copper differences in the degree of attenuation module. 交换机设备发送端通过调整芯片的输出信号(预加重配置)来测试是否满足铜缆模块互联端口之间的信号传输要求,接收端通过调整均衡功能实现接收端信号的优化。 The switch device output signal by adjusting the transmit end of the chip (pre-emphasis configuration) meets the test requirements of signal transmission between a copper interconnect module port, optimum reception terminal for receiving a signal by adjusting the balancing.

[0005] 目前发送端预加重配置方法主要有两种:信号测试筛选后固化配置和拷机测试。 [0005] The transmit pre-emphasis current configuration, there are two main methods: the test signal and the pager configuration cured test after screening. 信号测试筛选后固化配置是指通过对交换机设备在铜缆模块互联模式下,对各种预加重参数组合下的信号进行信号测试,选择信号最优的一组预加重参数进行配置。 After filtering the test signal of the switch means disposed curing equipment at the module copper interconnection pattern, signal pre-emphasis parameter combinations at various test signals by selecting a set of optimal signal pre-emphasis configuration parameters. 其优点是可以量化发送端的信号质量,更加直观,缺点是无法对每个型号的产品进行测试,同样设计的产品,因PCB (Printed Circuit Board,印刷电路板)差异、芯片差异或者case (屏蔽罩,用于插入光模块或者铜缆模块的容器)差异均会导致同型号不同产品存在个体差异,而信号测试无法完全覆盖到所有产品。 The advantage is quantized transmission signal quality end, more intuitive, the disadvantage of not testing for each of the products, the same design of the product, due to the PCB (Printed Circuit Board, PCB) difference, a chip or the difference case (shield for copper or optical module is inserted into the container module) will lead to differences in individual differences of different products of the same type, the signal can not completely cover all the test products. 拷机测试是指通过配置各种预加重参数组合,对产品进行拷机测试,验证产品的稳定性,与固化配置方法类似,其仍然无法覆盖所有的产品,降低了现有的预加重配置方法通用性。 It refers to various copying machine tests by the pre-emphasis configuration parameter combination, product copying machine tests to verify the stability of the product, and curing similar configuration, which still can not cover all products, reducing the conventional pre-emphasis configuration versatility.

[0038] 本发明各实施例中的方案可以应用于互联设备预加重配置中,其中,两台设备之间可以通过铜缆模块互联,也可以通过光模块互联,但是由于光模块信号质量较稳定,因此,本发明实施例尤其适用于通过铜缆模块互联的两台网络设备。 [0038] The various embodiments of the present invention may be applied to programs pre-emphasis network device configuration, wherein, between two devices over copper interconnect module, the optical module may be interconnected by, but because the signal quality of the optical module is stable Therefore, the embodiment is particularly suitable for two network devices interconnected by the copper module of the present invention.

[0039] 以下结合说明书附图对本发明的优选实施例进行说明,应当理解,此处所描述的优选实施例仅用于说明和解释本发明,并不用于限定本发明,并且在不冲突的情况下,本发明中的实施例及实施例中的特征可以相互组合。 [0039] The accompanying drawings in conjunction with the following description of preferred embodiments of the present invention, it should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention, and in the case of no conflict , features and embodiments of the present invention in embodiments can be combined.

[0040] 如图2所示,为本发明实施例的应用场景示意图。 [0040] As shown in FIG 2, a schematic diagram of an application scenario according to an embodiment of the present invention. 网络设备1配置有业务卡1,网络设备2配置有业务卡2。 The network device 1 is provided with a traffic card, network device 2 is configured with service card 2. 其中,业务卡1包含有端口XEO,ΧΕ1,以及CPLD (复杂可编程逻辑器件)、CPU(中央处理单元)1和MAC(介质访问控制)1,业务卡2包含有端口ΧΕΟ',ΧΕ1',以及CPLD、CPU2和MAC2。 Wherein the service card contains a port XEO, ΧΕ1, and a CPLD (complex programmable logic device), the CPU (Central Processing Unit) and a MAC (Media Access Control) 1, 2 includes a business card port ΧΕΟ ', ΧΕ1', and CPLD, CPU2 and MAC2. 在每一业务卡内,各器件之间的连接关系描述如下: Within each traffic card, connections between the devices described as follows:

[0041] CPU和MAC通过PCIE (Peripheral Component Interconnect Express)总线互联, 实现对MAC芯片的管理和配置,同时CPU负责部分三层协议报文处理。 [0041] MAC CPU and by PCIE (Peripheral Component Interconnect Express) bus network, the MAC chip to achieve management and configuration, while the CPU is responsible for message processing portion 3 protocol. CPU和CPLD通过local bus (LBUS,异步并行总线,经常用于接口FLASH\CPLD\UART控制器,也常用于IO接口控制器的初始化配置,甚至也用于数据通道)互联,CPLD实现接口转换,相当于一个桥梁,实现CPU 的管理数据通信,实现CPLD和其他器件的管理功能。 And CPLD by CPU local bus (LBUS, asynchronous parallel bus interfaces are often used FLASH \ CPLD \ UART controller, also commonly used in the initial configuration IO interface controller, even for a data channel) interconnected, CPLD implement interface conversion, corresponds to a bridge, the CPU manage data communication, to realize management of CPLD and other devices.

[0042] CPU和模块(光模块/铜缆模块)通过112接口互联,CPU是master设备,模块是s Iaver设备,实现对模块管理,如获取模块类型,速率等信息,需要通过CPU的II2通道。 [0042] and the CPU module (optical module / modules copper) interconnected via the interface 112, is the master CPU module is s Iaver equipment, and management module, such as module type acquisition, speed and other information required by the CPU channel II2 .

[0043] 模块和mac芯片之间直接通过高速serders信号互联,如果是IOG光模块,接口协议模式配置成SFI (SerDes (SERializer/DESerializer)串行接口,其为broadcom定义的一种协议,使用光模块时候配置为该协议模式)模式,如果是铜缆模块,配置成CR (SerDes (SERializer/DESerializer)串行接口,其为broadcom定义的另外一种协议,使用铜缆模块时候配置为该协议模式)模式。 [0043] directly via a high-speed signal interconnection serders, if IOG optical module, the interface protocol between the module and the mode configuration into chips mac SFI (SerDes (SERializer / DESerializer) serial interface which is a protocol defined broadcom, with light when the module configured for protocol mode) mode, if a copper module configured CR (SerDes (SERializer / DESerializer) serial interface, a second protocol which is defined broadcom, using copper mode module when configured for protocol )mode.

[0044] 模块和CPLD之间也是通过local bus互联的,主要是实现模块的信号采集和控制, 如prsent信号采集,速率控制等等。 [0044] between the module and the CPLD are interconnected by a local bus, mainly to achieve signal acquisition and control modules, such as prsent signal acquisition, the rate control and the like.

[0045] 在设备初始化阶段,MAC与模块之间被配置成默认配置,即被配置成SFI模式,且MC内部的PHY的预加重配置为默认配置,即被配置为使用背景技术中提供的方式确定出的预加重参数。 [0045] The apparatus is disposed between the initialization phase, the MAC module to a default configuration, i.e. arranged SFI mode, PHY and pre-emphasis MC arranged inside the default configuration, i.e. using a configuration provided in the background art determine the parameters of the pre-emphasis.

[0046] 上电后,可以通过CPLD和模块local bus接口的present信号检测模块是否在位; 如果模块不在位,不进行操作配置;如果在位,CPU通过II2C接口对模块类型进行识别,判断为光模块还是铜缆模块。 [0046] After power-on, the signal detection module can present CPLD, and local bus interface module is in place; if the module is not in position, without operating configuration; if in place, the CPU identified by II2C interface module type, it is determined The optical module or modules copper. 以下以铜缆模块为例进行说明,如果是光模块,其预加重配置方法与对通过铜缆模块相连的网络设备进行预加重配置相同,这里不再赘述。 In the following copper modules as an example, if the optical module is that the pre-emphasis configuration of network devices connected to the module over copper preemphasis same configuration is omitted here.

[0047] 具体实施时,若确定为铜缆模块时,将相应的端口配置为CR接口类型,CI3U通过PCIE接口读取MC的I ink (连接)状态寄存器位。 [0047] When particular embodiments, if the copper is determined as the module, the corresponding port configuration is CR interface type, CI3U MC is read I ink (connected) through the status register bits PCIE interface. 并判断端口是否与对端端口连接,如果没有连接,则不进行操作,如果检测到与对端端口建立连接,则按照本发明实施例提供的方法对MAC芯片进行预加重配置。 And determines whether the port is connected to the port terminal, if there is no connection, the operation is not performed, and if it detects establish connection port, the method according to an embodiment of the present invention, the MAC chip pre-emphasis configuration.

[0048] 需要说明的是,本发明实施例中涉及的端口广义上是指整个物理端口,如交换机中所涉及的端口形态中的每个形态就是唯一的端口;模块是指光模块或者铜缆模块,其是可热拔插的。 [0048] Incidentally, in the embodiments directed port of the generalized embodiment of the present invention refers to the entire physical ports, such as the shape of each switch port involved in the aspect of the port is the only; module refers to an optical module or copper module, which is hot-swappable. 需要用到对应端口时候,把光模块/铜缆模块插入到对应端口即可。 Need to use the corresponding port when the optical module / modules into copper appropriate ports. 因此,模块是端口使用时候必须存在的器件。 Thus, when the module is the port used must be present in the device.

[0049] 如图3所示,为本发明实施例一中互联设备预加重配置方法的实施流程示意图,包括以下步骤: [0049] FIG. 3, the present embodiment in the flow diagram of a pre-emphasis network device configuration method embodiment of the invention, comprising the steps of:

[0051] 具体实施时,在检测到本端端口与对端端口建立建立之后,本端CPU与对端CPU配置成VSU关系。 [0051] During specific embodiment, the relationship between the VSU is detected on the local port and remote port after Establishment, the local CPU and the CPU is configured to peer. 以图2中业务卡1的端口XEO和业务卡2的端口ΧΕ0'为例,两者在建立建立关系之后,CPUl与CPU2协商组建VSU。 Figure 2 business card with port and business cards XEO 1 port ΧΕ0 '2 as an example, both after establishing a relationship, CPUl CPU2 consultation with the formation of VSU. 建立了VSU之后,CPUl将端口XEO配置为VSL端口,CPU2将端口ΧΕ0'配置为VSL端口。 After establishing the VSU, CPUl XEO port configured as VSL port, CPU2 port ΧΕ0 'configured as VSL ports. CPUl携带业务卡1所属VSU域的标识,通过端口XEO向业务卡2的端口XEO '发送探测性报文,同时CPU2携带业务卡2所属VSU域的标识,通过XEO '向XEO发送探测性报文,两台独立设备构建成VSU系统,并且确定主从热备关系。 CPUl carrying identifier traffic card 1 belongs VSU domain, the business card ports XEO 2 through the port XEO 'transmits the probe of packets, while CPU2 carrying identify the service card 2 belongs VSU domain by XEO' to XEO sends a probe of packets , two independent devices constructed VSU system, and determining from the hot standby master relationship. 假设CPUl被确定为主,则本发明实施例中优先对端口XEO进行预加重配置。 Suppose CPUl is determined based, the embodiment of the present invention preferentially XEO preemphasis port configuration.

[0052] 需要说明的是,本发明实施例中,对端口XEO进行预加重配置,是指对与端口XEO相关的芯片进行配置,通常是对与端口XEO连接的芯片进行配置,对本例来说即是对MAC芯片进行配置。 [0052] Incidentally, embodiments of the present invention, port XEO preemphasis configuration, refers to associated with the port XEO chip configuration, typically the chip is connected to the port XEO be configured, for this example that is, the MAC chip configuration.

[0053] S32、本端从预加重配置表中依次选择一组预加重参数配置与本端端口连接的芯片后,利用配置的每一组预加重参数,分别在预设时长内持续向所述对端端口发送测试报文。 After [0053] S32, the local select a set of pre-emphasis configuration parameters chip connected to this end of the port configuration table from a pre-emphasis by the pre-emphasis configuration of each set of parameters, respectively, within a preset length of time to continue the port sends test packets to end.

[0054] 具体实施时,CPUl首先利用预设的预加重配置表中的第一组预加重参数配置MAC 芯片,并在预设时长内持续向对端端口ΧΕ0'发送测试报文,对端端口ΧΕ0'解析接收到的测试报文,MAC2判断每一测试报文中是否携带有错误报文,并且计算出误码率(在预设时长内,接收到的错误报文的数量与接收到的测试报文总数量的比值),依次类推,CPUl依次利用预设的预加重配置表中的第二组、第三组……预加重参数配置MAC芯片,并分别在预设时长内持续向对端端口ΧΕ0'发送测试报文,MAC2依次计算出每一组预加重参数对应的误码率,直至遍历预加重配置表中的每一组预加重参数。 [0054] In specific implementation, CPUl first predetermined pre-emphasis using a first set of pre-emphasis configuration parameters table MAC chip, and within a preset time duration to the length of the peer port ΧΕ0 'sends test packets, the peer port ΧΕ0 'parsing the received test packets, each test MAC2 is determined whether the packet carries an error message, and calculates the bit error rate (the number of error packets at the predetermined length, received with the received the ratio of the total number of test packets), and so on, CPUl sequentially by using a preset pre-emphasis configuration table second set, third set of parameters ...... MAC chip pre-emphasis, respectively, within a preset time and long duration of the end port ΧΕ0 'sends test packets, MAC2 is calculated sequentially for each set of pre-emphasis parameters corresponding to the bit error rate, until the pre-emphasis to traverse each group of pre-emphasis configuration table parameters.

[0055] 较佳的,具体实施时,测试报文可以为PRBS (伪随机二进制序列,Pseudo-Random Binary Sequence),CPU1构建PRBS码流,实现一个伪随机码二进制发生器,产生(0,1)之间的伪随机二进制序列,在预设时长内通过本端端口XEO持续向对端端口ΧΕ0'发送构建的PRBS码流。 [0055] Preferably, the specific embodiment, the test packets may PRBS (pseudo random binary sequence, Pseudo-Random Binary Sequence), CPU1 construct PRBS stream, to achieve a binary pseudo-random code generator which generates a (0,1 between the pseudo-random binary sequence), at a preset length of time by the local port to the remote port XEO continued ΧΕ0 'constructed transmitted PRBS stream. PRBS可以用于测试高速串行通道传输的误码率,通常通过发送PRBS码来进行测试。 PRBS bit error rate test may be used in high speed serial transmission channel, typically by sending a PRBS test. 利用PRBS得到的误码率比利用普通测试报文得到的误码率更加准确。 PRBS error rate obtained by the use of more accurate than the use of ordinary test packet error rate obtained.

[0056] 对端CPU在接收到PRBS码流进行验证,PRBS的验证就是PRBS的产生的反过程,具体方法是首先将收到的数据寄存一拍(并行数据),将寄存的数据进行PRBS编码,编码后的数据与接收到的数据进行比较,如果一致则表示PRBS校验正确,PBRS测试通过,否则PBRS测试不通过。 [0056] The CPU of the terminal to verify the received stream PRBS code, data validation is the inverse of the PRBS, a specific method of generating the PRBS register is first received one beat (parallel data), the registered data encoded PRBS , encoded data is compared with the received data, if the consistency check indicates correct PRBS, PBRS test passes, PBRS or the test fails.

[0057] S33、根据对端端口选择出的有效预加重参数配置与本端端口连接的芯片。 [0057] S33, the parameters emphasis chip connected to this end of the port based on the effective end of the port for a pre-selected.

[0058] 具体实施时,对端端口可以针对每一组预加重参数,判断在预设时长内是否接收到错误报文以及根据接收到的错误报文统计出误码率,以测试报文为PBRS为例,如表1所示: [0058] In specific implementation, the peer port may be pre-emphasis parameter for each set, it is determined whether the length of the received packet error when the preset bit error rate and according to the received packet error statistics to test packet is PBRS an example, as shown in table 1:

[0059] 表1 [0059] TABLE 1

[0060] [0060]

Figure CN104184617BD00091

ΐ〇〇6ΪΪ~具体实施时,只要接收到一条错误报文,即判定PBRS测试结果为fail (不通过),只, 有接收到的所有报文中不包含一条错误报文,才判定PBRS测试结果为Pass (通过)。 When particular embodiments ΐ〇〇6ΪΪ ~, as long as an error message is received, i.e., the determination result PBRS test fail (not through), only with all packets received does not contain an error message, it is determined that the test PBRS the result is pass (pass). 在选择有效预加重参数时,CPU2首先排除测试结果为fail的预加重参数组合,并从测试结果为成功(即接收到的错误报文的数量为零)以及误码率为零的预加重参数中选择任一组预加重参数作为有效预加重参数并通过XEO与ΧΕ0'之间建立的VSL链路通知CPUl,CPUl利用有效预加重参数对MAC芯片进行配置。 When selecting the pre-emphasis parameter valid, the CPU 2 first negative test results fail to pre-emphasis parameter combination, and from the test results in success (i.e., the number of error packets received zero) and bit error rate of zero pre-emphasis parameter selecting any of a set of pre-emphasis parameter for the effective pre-emphasis parameter and notification VSL through the link established between CPUl and XEO ΧΕ0 'of, CPUl effective use of pre-emphasis configuration parameters for the MAC chip.

[0062] 较佳的,具体实施时,CPU2可以从连续的测试结果为通过的预加重参数中选择中间为有效预加重参数,如表1所示的预加重参数标识为“N+2”及其下一条作为有效预加重参数通知业务卡1。 [0062] Preferably, the specific embodiment, the CPU 2 test results from the continuous pre-emphasis parameters selected intermediate pre-emphasis parameter is valid, as shown in Table 1 pre-emphasis parameter is identified as "N + 2" and under which a notification as an effective pre-emphasis parameter business card 1.

[0063] 具体实施时,在本端(即业务卡1)进行配置完成之后,进行翻转测试,即重复上述步骤对业务卡2进行预加重参数配置。 After the [0063] specific embodiments when carried out in this end configuration (i.e., traffic card 1), flip test, i.e., repeat the above steps for the traffic card 2 pre-emphasis parameters. 即由CPU2向CPUl发测试报文,CPUl进行解析分析后, 将选择出的有效预加重参数通告给CPU2,CPU2完成对应端口XEO '的预加重配置。 That is, after the test packet send by the CPUl CPU2, CPUl for analytical analysis, the selected advertisement to the effective pre-emphasis parameter CPU2, CPU2 complete the corresponding port XEO 'pre-emphasis configuration.

[0064] CPUl和CPU2在根据对端选择出的有效预加重参数对本端端口进行配置之后,释放建立的VSU,并分别将本端端口配置为普通交换端口。 [0064] CPUl and CPU2 after pre-emphasis parameter based on the effective end of the end of the selected configuration of the present port, established VSU released, respectively and the local port is configured as an ordinary switch port.

[0065] 具体实施时,由于环境变化导致的信号质量变化,以及铜缆模块和交换机设备使用时间导致设备老化引入的信号质量变化,使得铜缆模块互联端口之间传输的信号质量会随着环境参数变化而下降。 [0065] In specific implementation, since the signal quality variation due to environmental changes, as well as copper and switch device modules cause signal quality change time introduced by aging equipment, the quality of signals transmitted between the copper interconnect module with a port to the environment parameter changes and decline.

[0066] 为了解决上述问题,本发明实施例中,在对本端端口进行预加重配置之后,还可以记录配置预加重参数是的环境参数,在环境参数发生变化且满足预加重参数重配置条件时,重新为与本端端口连接的芯片配置预加重参数。 When [0066] In order to solve the above problems, embodiments of the present invention, after the present end of the pre-port emphasis configuration, can also record the configuration pre-emphasis parameter is the environmental parameters, a change in the environmental parameters and to meet the pre-emphasis parameters reconfiguration conditions re-chip configuration and port connectors of the present pre-emphasis parameters. 以环境参数为时间和温度为例,本发明实施例中在对本端端口进行预加重配置之后,记录配置时间和配置温度(本发明实施例中, 以被配置芯片的温度为配置温度)。 Environmental parameters as time and temperature, for example, embodiments of the present invention after the end of the preemphasis port configuration, configuration time and recording temperature configuration (embodiment of the present invention, a temperature is arranged to configure the chip temperature). 本端CHJ实时监控当前时间与当前MAC芯片的温度,在当前时间与配置时间的时间间隔大于预设时间间隔或者当前温度与配置温度大于预设温度间隔时,将重新为与本端端口连接的芯片配置预加重参数。 CHJ real-time monitoring of the local temperature of the current time with the current MAC chip, disposed in the current time interval is greater than a preset time interval or is currently configured with a temperature greater than the temperature interval a preset temperature, and re-present port terminal connected to chip pre-emphasis configuration parameters.

[0067] 另外,本发明实施例中,对端MAC芯片的counter寄存器实时监测接收到的报文中是否包含错误报文,一旦发现接收到错误报文,将向本端CHJ发送中断信号,本端CPU在接收到中断信号之后,将重新为与本端端口连接的芯片重新配置预加重参数,即重新执行上述步骤S31〜步骤S33。 [0067] Further, embodiments of the present invention, real-time monitoring of the counter registers the MAC chip ends received packet contains an error message, if it is found an error message is received, the local end will send an interrupt signal CHJ, the present after the end of the CPU receives an interrupt signal, the preemphasis again reconfigure parameters for the chip and connected to this end of the port, i.e. re-executes the steps S31~ step S33.

[0068] 需要说明的是,由于进行预加重参数配置需要占用一定的带宽资源,为了避免由于进行预加重参数配置占用带宽资源造成网络拥塞,本发明实施例中,可以确定当前存在网络带宽余量时,利用网络带宽余量进行预加重参数配置。 [0068] Incidentally, since the pre-emphasis parameter configuration occupies bandwidth resources, in order to avoid pre-emphasis parameter configuration network congestion bandwidth resources, embodiments of the present invention, it may determine a current presence of the remaining network bandwidth when using the pre-emphasis network bandwidth headroom parameters. 具体的,在重新进行预加重参数配置之前,统计当前转发报文占用的带宽,如果与进行预加重参数配置所占用的带宽之和超过当前网络最大带宽,则不重新进行预加重参数配置,如果其与进行预加重参数配置所占用的带宽之和不超过当前网络最大带宽,则重新进行预加重参数配置。 Specifically, before re-pre-emphasis configuration parameters, current statistics forwarded packets occupy bandwidth, if the emphasis parameter configuration occupied bandwidth with pre and beyond the current maximum network bandwidth is not re-pre-emphasis configuration parameters, if with pre-emphasis configuration parameters occupied bandwidth does not exceed the current maximum network bandwidth, then re-pre-emphasis configuration parameters. 由此,实现了预加重参数的动态配置,使其能够随着环境参数(如时间、温度等)的变化而动态调整,以保证任一时刻配置的预加重参数均为当前最优配置。 Thus, to achieve dynamic configuration of the pre-emphasis parameter, it is possible with the environmental parameters (such as time, temperature, etc.) changes dynamically adjusted to ensure that at any one time of the pre-emphasis configuration parameters are current optimum configuration.

[0069] 本发明实施例中,将互联的两台独立的网络设备配置成VSU,互联的两个端口配置为VSL,CPU构建伪随机码二进制生成器进行伪随机码二进制序列测试,对端配置成为伪随机码二进制校验器进行校验,从而筛选出最优的预加重配置参数并通知本端CPU,使其对本端进行预加重配置。 [0069] The embodiments of the present invention, the two interconnected network device is configured to separate the VSU, two interconnected ports configured to VSL, CPU construct pseudorandom binary code generator pseudorandom binary sequence code testing, remote configuration become a pseudo-random code binary checksum verifier, so the optimal pre-emphasis filter configuration parameters, and notify the end of the CPU, so that the end of the preemphasis configuration. 并且实时监控影响信号质量的关键环境参数,实现自适应配置,提高信号质量稳定性,增强应用的鲁棒性。 And real-time monitoring of key environmental parameters that affect signal quality, adaptive configuration to improve the signal quality stability, enhance the robustness of applications.

[0070] 本发明实施例可以应用于任何端口类型,任何虚拟交换机实现方式下的自适应配置。 Example [0070] The present invention is applicable to any type of port, the adaptive implementation of the virtual switches arranged.
