具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域的普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都属于本申请保护的范围。
为了解决相关技术中存在的上述技术缺陷，本发明实施例提供的技术方案的主要思路是：在100G交换机业务板卡的交换芯片和物理接口收发器(PHY)之间(即系统侧)的高速信号4*25G、12/10*10G和1*100G的基础上，结合数据接口收发器(PHY)和光模块之间(即链路侧)支持CXP、CFP2SR10、CFP2LR4/ER4、N*QSFP+、N*SFP+等光模块端口，实现业务板卡基于端口的自由网络布局，在不改变硬件设备的基础上，通过软件实现100G端口容量的动态可分配。
实施例一
本发明实施例提供了一种端口容量分配方法。图1是根据本发明实施例的端口容量分配方法流程图，如图1所示，该流程包括以下步骤(步骤S102-步骤S106)：
步骤S102、接收网管系统发送的用于指示对交换机业务板卡的端口进行动态端口配置的指示消息，其中，指示消息包括需要配置的端口的目的端口模式信息；
步骤S104、根据每个端口支持的光模块的类型，将该端口配置为符合目的端口模式信息的一个或多个虚拟端口；
步骤S106、按照用户的业务需求，将配置得到的所有虚拟端口分配给多个虚拟交换机，使得交换机业务板卡的端口容量通过虚拟交换机的虚拟端口得到重新分配。
在实际应用中，交换机业务板卡的种类有很多，例如40G交换机业务板卡，100G交换机业务板卡，由于目前100G交换机业务板卡的应用比较广泛，因此本发明实施例重点对100G交换机业务板卡的光模块的端口进行容量动态分配，相对于传统比较单一的端口容量使用模式，可以满足用户多样化的容量使用需求。
在本发明实施例中，端口支持的光模块的类型可以包括：CXP 100G-SR12、CFP2/CFP4 100G-SR10、CFP2/CFP4 100G-LR4、或者CFP2/CFP4 100G-ER4。
根据这几种光模块的类型，上述步骤S104中对光模块的端口进行配置的过程可以通过以下方式实现：
(1)在端口支持的光模块的类型为CXP 100GE-SR12的情况下，可以将该端口配置为SFP+12*10G SFI虚拟端口、QSFP+3*40G XLAUI虚拟端口、或1*100G GAUI虚拟端口。
(2)在端口支持的光模块的类型为CFP2/CFP4 100G-SR10的情况下，可以将该端口配置为SFP+10*10G SFI虚拟端口、QSFP+2*40G XLAUI虚拟端口、或1*100G GAUI虚拟端口。
(3)在端口支持的光模块的类型为CFP2/CFP4 100G-LR4或CFP2/CFP4100G-ER4的情况下，可以将该端口配置为1*100G GAUI虚拟端口。
在本发明实施例中，上述步骤S106可以通过这样的方式来实现：先基于虚拟逻辑设备(VLD)功能，按照业务需求对所有虚拟端口进行分组，并将每组虚拟端口划分到符合业务需求的虚拟交换机中。
可选地，所述方法还包括：在执行上述步骤S102之前，还可以先根据交换机业务板卡的业务类型，配置交换机业务板卡内部的交换芯片和PHY之间的端口映射关系和交换芯片的信号属性；再根据映射关系和信号属性初始化交换芯片和PHY。
这样做的目的是为了上述方式(1)(2)(3)中对端口进行拆分或合并 的过程做准备工作。
在实际应用中，上述实施例可针对100G交换机业务板卡接入多种类型光模块的兼容支持和虚拟化多种端口容量的场景进行应用，由于CXP和CFP2光模块具有封装区别，因此可以依据业务板卡的类型区分确定业务板卡使用的端口和映射关系，通过交换芯片(MAC)和物理接口收发器(PHY)间的Serdes速率为4*25G、12/10*10G或1*100G进行设置，再根据物理接口收发器和光模块之间对应的CXP、CFP2SR10、CFP2LR4/ER4，10*SFP+接入特性，以及物理接入光模块类型，对100G业务板卡的任意端口进行独立的动态拆分和合并，依据光模块特性的不同，如果端口接入CXP光模块，可以用作1*100G或3*40G或12*10G端口使用，如果端口接入CFP2SR10光模块，可以用作1*100G或2*40G或10*10G端口使用，如果端口接入CFP2LR4/ER4光模块，可以用作100G端口使用。
结合基于端口的虚拟化技术，可对100G交换机板卡的端口容量进行组合布局，将端口自由划分在每个虚拟化交换机里面，不仅实现了100G业务板卡的端口容量动态设置，且可以通过虚拟化实现整体网络结构端口容量灵活的网络部署和管理。
实施例二
为便于理解上述实施例提供的端口容量分配方法的实现过程，以下结合实施例二和附图2至5进行更加详细的描述。
该实施例主要以100G交换机业务板卡为例进行说明。外部接口物理端子包括100G CXP和100G CFP/CFP2/CFP4等几种类型的端口，该实施例可以使交换机业务板实际物理端子做到对不同类型100G光模块的兼容，并动态管理端口属性为1*100G/M*40G/N*10G，基于端口虚拟化到不同交换设备中，能够将端口容量灵活分配到网络布局中。
图2是根据本发明实施例的端口链路搭建示意图，请参考图2以便于理解，假设图2中的单个业务板卡的外部端口为M个CXP端口或者N个CFP2端口，通过业务板卡的类型属性和交换芯片属性，可以识别交换芯片MAC 对接物理接口收发器PHY的高速Serdes链路为12/10*10G、4*25G、1*100G通路，作为100G链路的HOST侧(即系统侧)，PHY芯片的LINE侧(即线路侧)通过动态的端口属性管理搭载10*10G CAUI、4*28VSR、3/2*40G XLAUI、10*10G SFI。
对于M个CXP端口的业务板卡来说，每个端口对接的光模块为CXP 100G-SR12，可以通过网管系统动态设置单个端口为100G还是拆分成3个40G端口或12个10G端口，且M个CXP 100G端口可以独立的动态分配端口容量。当1个CXP端口作为1个100G端口使用时，通过MPO(Multi-fiber Push On)光纤对接其它CXP 100端口使用，当1个CXP端口被拆分成3个40G端口使用时，需要通过MPO转接光纤对接其它的3个40G QSP+端口使用，当1个CXP端口被拆分成12个10G端口使用时，需要通过MPO转接光纤对接其它的12个10G SFP+端口使用，其它的M-1个CXP端口同理适用此应用。
对于N个CFP2端口的业务板卡来说，每个端口对接的光模块为CFP2 100G-SR10或者CFP2 100G-LR4/ER4，可以通过网管系统动态设置单个端口为100G还是拆分成2个40G端口或10个10G端口，CFP2 100G-SR10光模块链路采用10*10G，可以进行动态拆分合并。但是，由于100G-LR4/ER4光模块链路采用4*25G，故无法进行动态拆。当1个CFP2端口拆分成2个40G端口或者10个10G端口时，只有对接CFP2 100G-SR10光模块才能正常使用，通过MPO转接光纤分别对接40G或10G端口，当1个CFP2端口作为1个100G端口使用时，可以对接CFP2 100G-SR10或者100G-LR4/ER4光模块，并通过光模块类型获取，返回驱动物理接口收发器和交换芯片特性，使其自动支持CFP2 100G不同类型光模块的使用。N个CFP2 100G端口可以独立的动态分配端口容量，在上层管理设备动态分配端口属性之后，需要结合前述的CFP2特性接入相应类型的光模块。
在实际应用中，端口接入CXP光模块可以动态拆分为12*10G端口、3*40G端口或合并为1*100G端口，端口接入CFP2 SR12光模块可以动态拆分为10*10G端口、2*40G端口或合并为1*100G端口，依据光模块器件特性适合于几百米的传输，CFP2 LR4以及CFP2 ER4适合于长距离传输且仅能作 为1*100G端口，不同类型的端口的传输距离情况是：CXP 100G-SR12的传输距离为100-800m，100G CFP2/CFP4-SR10的传输距离为100-800m，100G CFP2/CFP4-LR4的传输距离为10Km，100G CFP2/CFP4-ER4的传输距离为30Km。因此，100G交换机业务板卡不仅仅局限于单一的100GE使用，多样化的端口传输距离能较大程度满足用户的业务需求，而是基于端口的动态分配即对外部端口都可灵活管理。
图3是根据本发明实施例的端口链路内部实现的逻辑结构示意图，如图3所示，该逻辑结构采用双向循环链表作为驱动层的端口资源管理池，头结点为端口通用属性资源，包括交换机业务板卡的基本信息、端口映射关系、Serdes速率、以及交换芯片内部端口属性等。
当识别到具体的业务板卡类型时，加载相应的端口通用属性资源，并进行交换芯片(MAC)的端口初始化，结合挂接的数据接口收发器(PHY)和光模块相关初始化，会在双向链表中增加新结点。依据本业务板卡上电前一次运行的保存端口容量分配特性，建立后续初始结点，业务板卡启动完成后，网管系统动态拆分合并端口时，该逻辑结构中的双向链表会相应的增加结点或删除结点。
例如，当全部端口按照100G启动时，假设每个交换芯片(MAC)支持两条100G数据链路，端口建立为unit-0/port-1结构体结点和unit-0/port-13结构体结点，更多的交换芯片unit以此类推。当本业务板启动完成后，该端口资源管理池建立完毕。例如，针对CXP端口操作，若网管系统对uni-0/port-1进行动态拆分成12个10G端口时，通过修改unit-0/port-1结构体相关属性，并从unit-0/port-1位置增加结点，即可以建立unit-0/port-2到unit-0/12结点以及填充相关属性值。若对uni-0/port-1到unit-0/port-12这12个10G端口进行端口动态合并，则在双向循环链表中删除unit-0/port-2到unit-0/12结点，并修改unit-0/port-1结构体相关属性。若对unit-0/port-1进行动态拆分成3个40G端口时，通过修改unit-0/port-1结构体相关属性，并从unit-0/port-1位置增加结点，即可以建立unit-0/port-5、unit-0/port-9结点以及填充相关属性值。对于unit-0/port-13进行动态拆分合并操作，其与unit-0/port-1类似。
图4A是根据本发明实施例的100G板卡端口容量布局的实现过程示意图， 如图4所示，100G板卡启动时，系统会识别交换机业务板卡的相关特性以判断是否支持CXP业务板卡或CFP2/4业务板卡，在确定支持的情况下，配置端口映射关系和交换芯片的高速信号属性，在交换芯片初始化过程中，进行数据接口收发器(PHY)芯片的初始化，依据保存的端口配置，结合外部端口接入的光模块类型，自动管理端口状态。
图4B是根据本发明实施例的100G板卡端口容量分配流程示意图，如图4B所示，该流程包括以下步骤：
步骤S402，进行端口的拆分或合并动作；
步骤S404，设置源端口模式和目的端口模式，并记录要操作的芯片号和端口号；
步骤S406，创建新的芯片端口位图；
步骤S408，进行清除端口速率，将端口出向入向的每个子模块带宽设置信息，以及与端口相关通路数据全部清空；
步骤S410，进行端口配置信息调整，移除旧端口配置，增加新端口配置；
步骤S412，设置端口速率，将端口出向入向的每个子模块带宽进行设置，并且使得端口具备收发报文特性；
步骤S414，对数据接口收发器(PHY)驱动进行调整，以兼容不同100G光模块；
步骤S416，最终更新端口资源管理池；
步骤S418，通告相关业务模块端口变更。
在图4A所示的容量布局的实现过程中，如果识别出是M个CXP端口的业务板卡，那么端口可以接入CXP 100G-SR12光模块，并可在1×100G CAUI、12×10G SFP+和3×40G QSFP+等端口模式中进行切换，且M个端口都可进行动态的独立调整。
如果识别是N个CFP2端口的业务板卡，那么端口就可以接入CFP2 100G-SR10或者CFP2 100G-LR4/ER4光模块，端口配置和光模块接入之间相互独立，但是，只有在满足CFP2 100G-SR10时，可以进行1×100G CAUI、 10×10G SFP+和2×40G QSFP+的来回端口模式切换，CFP2 100G-LR4/ER4仅支持1×100G CAUI，在这样的端口模式设置情况下，交换机数据链路端口才能够正常工作。假设出现对接异常的情况，系统会告知网管系统端口模式不匹配或接入光模块类型不匹配等相关故障信息。
例如，业务板卡的端口为CXP 100G-SR12光模块，启动时默认按照100G启动，若其中一端口根据保存的端口配置为被拆分的12个10G端口，那么系统会依据源端口模式为100G CAUI，目的端口模式为10G SFI进行端口拆分动作，按照上述的操作步骤，最终将1个100G端口拆分成了12个10G端口，并反馈至上层网管系统。在业务板卡运行过程中，若需要对12个10G端口进行合并，在不影响其它端口正常工作情况下，系统可以依据源端口模式为10G SFI，目的端口模式为100G CAUI的情况进行端口合并动作，1个100G端口和3个40G端口的动态调整同理执行，M*40G和N*10G之间的端口变换需要通过合并为100G端口后再拆分实现相应的端口容量更替。CFP2业务板卡同理实现。
对于上层网管系统，其还可以动态调整基于单个端口的端口属性，并对基于端口进行VLD一虚多，达到灵活的端口容量分配和端口隔离功能。
图5是根据本发明实施例的网络部署示意图，如图5所示，交换机业务板卡的100G端口被自由分配为12*10/10*10G SFI、3*40/2*40G XLAUI、1*100G CAUI，依据前述的M个CXP端口或N个CFP2端口的业务板卡特性，结合实际网络用途，可以对业务板卡的端口进行灵活分配，交换机业务板卡正常运行时可适时调整端口特性，每个100G端口动态更换端口容量互不影响，解决当前的单一端口模式的使用，增强100G业务板卡的应用场景。
再结合VLD一虚多功能，将端口灵活分布在不同的虚拟化交换机设备中，可自由组合端口对接下层或上层网络设备，并可以对其进行分开独立的管理。在100G交换机业务板卡端口模式动态调整的基础上，结合VLD虚拟化功能，能够最终实现端口容量灵活布局。
如图5所示，交换机业务板卡(1)的物理编号1的端口被拆分成多个40G或10G逻辑端口，并依据公司①的部门A和部门B的网络容量需求对接下层网络设备，部门C同理对接单个100G逻辑端口，并对本业务板卡的 物理端口PORT1到m个划分按照端口配置划分的多个逻辑端口，设置为VLD1虚拟化设备，公司②同理按照实际需求分配，并设置在VLD2虚拟化设备中，且可以基于端口分布的VLD一虚多功能，能够将跨业务板卡的不同逻辑端口分配到相同虚拟化交换设备中，例如，图5中的VLD3。这样不仅实现了物理端口的端口容量灵活分布问题，还可独立地管理不同容量逻辑端口。
实施例三
