longest subnet mask). This process enables faster routing decisions within routers. The MPLS label identifies something called a Forwarding Equivalence class (FEC). All packets that belong to a given FEC are treated equally for the purposes of forwarding. All packets in a given stream of data, such as a voice call, will have the same FEC and receive the same forwarding treatment. Therefore, we can ensure that the forwarding treatment applied to a given stream can be set up such that all packets from A to B follow exactly the same path. If that stream has a particular bandwidth requirement, then that bandwidth can be allocated at the start of the session. Thus, we can ensure that a given stream has the bandwidth that it needs and the packets that make up the stream arrive in the same order as transmitted. Hence, a higher QoS is provided. Not only can we ensure that a given session can be given the required bandwidth and that all packets in a session are forwarded the same way, but we can apply the same technique to a traffic aggregate. For example, we can apply the same FEC to all voice packets between two media gateways (MGs) that are geographically separate. Consider a VoIP network that provides long-distance voice service. Such a network would have numerous gateways in different locations. Provided that we have an understanding of the traffic demand between a given pair of media gateways, we can allocate a specific path (with specific resources) through the IP network to handle the traffic between those gateways. Also, if the traffic between the gateways does not exceed expectations, then the traffic will always have access to the necessary network resources to ensure that QoS requirements are met. This approach (whereby we allocate specific paths and network resources to specific types of traffic) is known as traffic engineering. In fact, MPLS is effectively a traffic-engineering tool and it ensures QoS by enabling us to ensure that the network is correctly engineered to meet our QoS objectives.
