51 Work to Date: MPLS Enhancements to VoIP
The majority of Section 51 has been selected from George Swallow s article MPLS Enhancements to VoIP 2 Many parts of Swallow s article have been reprinted here for this discussion
511 Benefits of Traffic Engineering
If voice and data applications are to be mixed in a single network, attention must be paid to the QoS of the voice application Data, which usually ride on TCP, respond gracefully to transient congestion TCP ensures the reliable delivery of data; if packets are dropped, TCP retransmits them TCP responds to congestion by backing off the rate it sends At an aggregate level, this keeps the traffic in the network within reasonable bounds for data applications Voice is severely impacted by network congestion Excessive delays cannot be tolerated A packet containing voice cannot be played if it is received late If packets are lost, retransmission is not an option because they will very likely arrive too late A quality voice service demands low delay and low loss There are three elements in achieving QoS First the network resources must be committed to the voice application Second the traffic must be marked, so that at each point of congestion, the committed resources can be applied to the guaranteed flow Third the amount of marked traffic must be kept at or below the amount of bandwidth committed to the flow When network resources are committed to the voice application, it has to be done on an accounting basis, link by link MPLS traffic engineering (TE) provides the means of achieving this Traffic engineering uses RSVP to reserve resources for the voice flows For example, if the shortest path (that is, the normal IP route) has too few resources, traffic engineering can use an explicit route to send the flow on a less congested path The MPLS label information provides a means of marking the traffic As RSVP sets up an MPLS traffic-engineering tunnel, it also assigns the labels to be used by the flow These labels plus the EXP bits (QoS-specific bits that are carried along in the label information) provide a simple and, and in many proponents view, a scalable way of identifying the voice flows (This is the diffserv approach discussed in 33 An intserv approach is also available) The traffic-engineering tunnels can be employed like voice tie lines4 Consider a tunnel between two voice gateways The tunnel can be sized to the expected number of calls As calls arrive that are destined to the remote gateway, they are routed over the tunnel by applying the appropriate MPLS
Motivations, Drivers, Approaches, and Advantages of VoMPLS
label By aggregating calls into tunnels, network scalability is enhanced Intermediate nodes need not be aware of individual calls; they only deal in the aggregated tie lines All of the voice calls within the tunnel are marked with the same MPLS label At each intermediate node, the packets belonging to the voice flow are identified solely by the MPLS label information Intermediate nodes have a simple and scalable means of applying the proper queuing treatment to the flow If the number of calls received exceeds the call capacity of the tunnel, several options exist A dynamic capacity adjustment strategy can be used As a tunnel nears its call capacity, the voice gateway can signal a new tunnel or request increased capacity for the existing tunnel Or, the gateway may address the problem at the call control level by routing through an alternate gateway or directing the call offnet Finally, the call can be blocked and a busy signal will be returned In all events, the call load is carefully regulated so as not to exceed the reserved network resources Thus, MPLS provides an effective and scalable means of allocating resources, marking voice flows, and matching the number of voice calls to network resources Hence, a high-quality voice service can be guaranteed
