MPLS (Multiprotocol Label Switching) is a high-performance, scalable routing technology used to forward packets based on labels instead of IP addresses. It’s widely used in service provider networks and enterprise WANs for speed and traffic engineering.
MPLS allows you to: Forward packets faster by using labels Create virtual paths (Label Switched Paths - LSPs) Separate traffic types (e.g., voice vs. video vs. web) Support VPNs, Traffic Engineering (TE), and Quality of Service (QoS)
QoS (Quality of Service) is a network feature that prioritizes traffic types to ensure high performance for critical applications like: Voice (VoIP) Video conferencing Business apps (ERP, CRM)
MPLS and QoS work together to: Prioritize traffic across Label Switched Paths Guarantee bandwidth for critical services Avoid packet loss, delay, and jitter Enforce traffic classes (e.g., Expedited Forwarding for VoIP)
1. Classification – Identify traffic type 2. Marking – Add labels/fields to identify priority 3. Policing – Drop or remark out-of-policy traffic 4. Shaping – Smooth traffic flows 5. Queuing/Scheduling – Prioritize and forward based on traffic class
The EXP (Experimental) bits in the MPLS header are used for QoS marking. These 3 bits allow up to 8 different traffic classes, similar to IP precedence or DSCP values.
Traffic Engineering in MPLS is used to manually control how traffic flows through the network, instead of relying on traditional routing like OSPF or BGP. This lets you: Avoid congested paths Allocate bandwidth per class Meet SLAs (Service Level Agreements)
Traffic can be classified based on: IP source/destination Port numbers Protocol types DSCP/ToS values (in IP header) MPLS EXP bits
In Cisco IOS, you’ll use: class-map and policy-map for classification and marking mpls qos and mpls traffic-eng commands service-policy to apply QoS to interfaces DiffServ and IntServ models
At the ingress PE router (Provider Edge), classify and mark the traffic. Inside the MPLS core, EXP bits are used to enforce QoS policies. Egress PE can remark or process traffic based on SLAs.
