Abstract: In one example, an edge routing device of a service provider network includes one or more network interfaces configured to send and receive packets and a processing unit configured to retrieve, from a packet received via the one or more network interfaces, priority data from an Internet protocol (IP) header of the packet, form a first tag including a first set of data in a first priority field of the first tag, wherein the first set of data represents a first portion of the priority data, form a second tag including a second set of data in a second priority field of the second tag, wherein the second set of data represents a second portion of the priority data, encapsulate the packet with the first tag and the second tag, and forward, via the one or more network interfaces, the encapsulated packet.

Abstract: Techniques are described for applying double experimental (EXP) quality of service (QoS) markings to Multiprotocol Label Switching (MPLS) packets. According to the techniques, an edge router of an MPLS network is configured to map a Differentiated Services Code Point (DSCP) marking for customer traffic to at least two EXP fields of at least two different labels included in a MPLS packet encapsulating the customer traffic. In this way, the edge router may map the full DSCP marking across the first and second EXP fields to provide full resolution QoS for the customer traffic over the MPLS network. The techniques also include a core router of an MPLS network configured to identify a QoS profile for a received MPLS packet based on a combination of a first EXP field of a first label and a second EXP field of a second label included in the MPLS packet.

Abstract translation: 描述了将双重实验（EXP）服务质量（QoS）标记应用于多协议标签交换（MPLS）分组的技术。 根据该技术，MPLS网络的边缘路由器被配置为将用于客户业务的差分服务码点（DSCP）标记映射到包含在封装客户业务的MPLS分组中的至少两个不同标签的至少两个EXP字段。 以这种方式，边缘路由器可以在第一和第二EXP字段之间映射完整的DSCP标记，以为MPLS网络上的客户业务提供全分辨率QoS。 这些技术还包括MPLS网络的核心路由器，其被配置为基于包括在MPLS分组中的第一标签的第一EXP字段和第二标签的第二EXP字段的组合来识别接收的MPLS分组的QoS简档。
