具体实施方式
下文中将结合附图对本申请的实施例进行说明。
BIER技术在新的网络架构下，为各类大视频业务提供了高效的组播解决方案，提升了网络效率。图1是相关技术提供的一种BIER头封装格式的示意图。该BIER头封装格式基于多协议标签交换(Multi-Protocol Label Switching，MPLS)数据面，BIER消息格式定义如图1所示。
随着BIER技术在组播业务的广泛应用及网络规模的扩大，为了保障BIER报文的有效传输，操作维护管理(Operation Administration and Maintenance，OAM)功能是多协议标签交换(MPLS)网络可管理可运营的基本要求，BIER OAM基于MPLS OAM的机制进行扩展，它的主要功能是有效提升BIER网络的管理和维护能力，保障网络的稳定运行。根据国际互联网工程任务组(Internet Engineering Task Force，IETF)标准中的定义，BIER OAM报文紧随BIER头后，使用BIER头中的原型(Proto)字段识别BIER OAM报文，如果Proto字段设置为5，则表明紧随BIER头的报文为BIER OAM报文。在BIER OAM头中的Proto字段为非0的情况下，后续报文携带为业务报文。图2是相关技术提供的一种BIER OAM头封装格式的示意图，BIER OAM消息格式定义如图2所示。
性能测量(Performance Measurement，PM)是BIER OAM技术需关注的重点，BIER PM通过测量报文的延时、抖动和丢包率，实现BIER网络的性能测量。在标准定义中，请求评论(Request For Comments，RFC)7799定义了测量方法的分类，RFC8321定义了被动性能测量方法，其中，标记方法(Marking Method，MM)可以通过标记特定数目或特定时间间隔内的报文实现测量实时流量的报文丢失、时延和抖动等。BIER网络也可以使用标记方法测量组播报文丢包率、时延等属性，包括单标记测量和双标记测量。如图1所示，IETF RFC8296规定的BIER头封装格式基于MPLS数据面，其中包含2bit的OAM字段，用来指示标记性能测量方法。图3是本申请实施例提供的一种BIER头中OAM字段格式的示意图。如图3所示，S比特置1时，表明是单标记测量，当D比特置1时，表明是双标记测量。但在标准中，未定义基于流的测量方法，未定义如何识别BIER流，无法实现基于BIER流的性能测量功能。
根据IETF标准的定义，BIER网络可以使用被动的标记测量方法。比特转 发路由器(Bit-Forwarding Router，BFR)节点进行丢包和时延测量，可以在源或宿节点执行节点、链路、子网或端到端测量。用户可以在一个BFR创建不同的BIER子流，每个子流包含了标记报文，可以在BIER网络内的报文流经过的任意BFR监控点识别并测量丢包率和时延。标记点可以在BIER网络的边缘节点设置或清除，以识别特定BIER子流，从而测量该BIER子流的丢包时延等性能。本申请实施例提出一种BIER网络中基于流的性能测量方法，该方法基于流的BIER报文封装，扩展流(Flow)字段，实现BIER流的识别及BIER流的标记性能测量功能。在实施例中，流字段的长度32比特，流字段携带BIER流识别信息。

在一实施例中，BIER流识别信息由网络管理系统(Network Management System，NMS)或控制器生成，用于识别待检测的BIER流，可适用于MPLS，非MPLS以及互联网协议第6版(Internet Protocol version 6，IPv6)等多种数据面。
