以下结合附图对本发明的实施例作进一步详细说明。
本发明实施例提供的技术方案可适用于图1所示的一种FlexE的网络架构中。该网络架构包括第一网络设备和第二网络设备。
网络设备(例如第一网络节点、第二网络节点等)是灵活以太网中具备数据收发功能的设备，例如支持灵活以太网功能的路由器、交换机等。第一网络节点和第二网络节点之间具有至少一条以太网物理链路。
图2是第一节点和第二节点灵活以太网接口连接及第二节点灵活以太网组可绑定接口合集信息示例图。两节点各包含16个灵活以太网接口，通过其中4个接口相连。
优选的，第二节点与第一节点相连的4个接口均可绑定至同一个灵活以太网组。但由于第二节点无法获取到第一节点与第二节点相连的4个接口支持绑定至同一个灵活以太网组的能力信息，影响灵活以太网组链路创建，导致灵活以太网链路管理效率较低。
为提高灵活以太网链路管理效率，本申请实施例提供一种灵活以太网链路管理方法，网络节点可获取到所有邻接节点所述信息以创建灵活以太网组。下面结合图3，对本申请的方法实施例进行详细描述。
图3是本申请实施例提供的灵活以太网链路管理方法的流程示例图。所述灵活以太网至少包含两个网络节点，通过至少一个灵活以 太网接口相连。
图3的方法如下：
S1、对第一节点和第二节点的灵活以太网接口编号，所述编号在该节点下唯一。
S2、第一节点和第二节点获取本节点所有FlexE接口的编号绑定信息，所述编号绑定信息包括：该FlexE接口的编号，支持与该FlexE接口绑定至同一个灵活以太网组的FlexE接口编号合集。
S3、第一节点选取与第二节点相连的FlexE接口，将所述FlexE接口的编号绑定信息封装在FlexE开销帧中，发送给第二节点。
S4、第二节点与第一节点相连的所有FlexE接口获取到所述第一节点FlexE接口的编号绑定信息后，获得第二节点与第一节点链路属性信息，所述链路属性信息包括：第二节点与第一节点相连的FlexE接口编号对；第二节点可用于与第一节点创建灵活以太网组链路的FlexE接口编号合集。
所述流程同时适用于第一节点和第二节点，即第一节点也可依据所述流程获得第二节点的所述链路属性信息。
优选的，网络节点可通过管理或控制通信通道获取相邻节点标识信息，如节点IP地址等，配合所述链路属性信息，完成灵活以太网灵活以太网组创建。
图4至图8是对图3所述流程实现方式的详细说明。
步骤S1如图4所示，对第一节点和第二节点各自16个FlexE接口编号1-16，第一节点接口5、6、7、8分别与第二节点接口1、2、3、4相连。第一节点接口4、5可绑定至同一个灵活以太网组，接口6、7、8可绑定至同一个灵活以太网组；第二节点接口1、2、3、4可绑定至同一个灵活以太网组。
应理解，所述网络节点FlexE接口数量16，仅为本申请实施例的一种实施场景，网络节点FlexE接口数量可根据实际情况而定，本申请实施例在此不做限定。
优选的，步骤S2以第一节点和第二节点相连接口为例：
第一节点接口编号，及支持与该接口绑定至同一个灵活以太网组的接口编号合集如表1所示；
表1 第一节点接口编号合集
接口编号 5 6 7 8
二进制位图 0b11000 0b11100000 0b11100000 0b11100000
十进制位图 24 224 224 224
第二节点接口编号，及支持与该接口绑定至同一个灵活以太网组的接口编号合集如表2所示。其中接口编号合集信息以比特位图方式表达。
表2 第二节点接口编号合集
接口编号 1 2 3 4
二进制位图 0b1111 0b1111 0b1111 0b1111
十进制位图 15 15 15 15
以第一节点接口5为例，接口5支持与接口4绑定至同一个灵活以太网组，则接口5对应编号合集为0b11000，即比特3和比特4为1，其他比特位为0，此处假设右起起始比特位为比特0。
优选的，步骤S3如图5和图6所示，以下分别对图5和图6进行说明。
图5是采用FlexE开销帧备用比特承载所述信息的格式说明。FlexE开销帧由8个66比特开销块组成，32个开销帧序列组成1个开 销复帧。开销帧第二个66比特块比特17至比特63和第三个66比特块比特35至比特47为保留比特位。第一节点接口数量不超过512个时，采用开销帧第二个66比特块备用比特17至比特25承载所述编号绑定信息，采用开销复帧的32个开销帧第二个66比特块备用比特26至比特40承载所述接口编号合集信息，发送给第二节点。
应理解，所述FlexE开销帧备用比特承载所述信息的格式，仅为本申请实施例的一种实施方式，还可以采用其他保留比特位承载所述信息，或当节点支持的最大接口数量不同时，采用更多或者更少的保留比特位承载所述信息，本申请实施例在此不做限定。
图6是采用FlexE接口提供的管理通道承载所述信息的格式说明。在管理通道中可携带LLDP协议IEEE802.1AB，用于接口间连接性验证。如图6所示，在LLDP TLV扩展中加入OIF OUI，并引入新的子类型4，标识后续字节用于承载所述信息。所述编号绑定信息和接口编号合集信息分别占用2字节和64字节，由LLDP TLV扩展承载，由第一节点发送给第二节点。
应理解，所述FlexE管理通道携带LLDP承载所述信息的格式，仅为本申请实施例的一种实施方式，LLDP TLV扩展还可通过其他格式承载所述信息，本申请实施例在此不做限定。
优选的，步骤S4以第一节点和第二节点相连接口为例，第一节点和第二节点接口编号对，及第一节点可用于与第二节点创建灵活以太网组链路，且包含该第一节点端口接口的接口编号合集如表3所示；
表3 第一节点和第二节点接口编号对
接口编号对 5-1 6-2 7-3 8-4
二进制位图 0b1000 0b11100000 0b11100000 0b11100000
十进制位图 8 224 224 224
第二节点和第一节点接口编号对，及第二节点可用于与第一节点创建灵活以太网组链路，且包含该第二节点端口接口的接口编号合集如表4所示。其中接口编号合集信息以比特位图方式表达。
表4 第二节点和第一节点接口编号对
接口编号对 1-5 2-6 3-7 4-8
二进制位图 0b1 0b1110 0b1110 0b1110
十进制位图 1 14 14 14
优选的，以第二节点接口2为例，该接口与第二节点接口6相连，则接口编号对为2-6；第二节点接口2支持与接口1、3、4绑定至同一个灵活以太网组，由步骤320可知，接口编号合集为0b1111。第一节点对应相连接口5、6、7、8中，接口5不支持与接口6、7、8绑定至同一个灵活以太网组，则编号对1-5无法参与编号对2-6绑定至同一个灵活以太网组链路。因而接口对2-6对应可创建灵活以太网组链路的编号合集为0b1110，即比特1、比特2和比特3为1，其他比特位为0，此处假设右起起始比特位为比特0。
应理解，步骤S2和步骤S4所述合集通过比特位图方式表达，仅为本申请实施例的一种实施方式，还可以采用其他表达合集信息的方式，本申请实施例在此不做限定。
