PVC instead of a dynamic SVC SVCs are actually good for backup purposes you might have a primary PVC to a site that costs X dollars a month and a backup SVC that costs you money only if you use it, and then that cost is based on how much you use it perhaps based on the number of minutes used or the amount of traffic sent If your primary PVC fails, the SVC is used only until the primary PVC is restored To determine whether you should be using an SVC or PVC, you ll need to weigh in factors such as the amount of use and the cost of a PVC versus that of an SVC given this level of use Another advantage of SVCs is that they are adaptable to changes in the network if there is a failure of a physical link in the carrier s network, the SVC can be rebuilt across a redundant physical link inside the carrier s network The main disadvantages of SVCs are the initial setup and troubleshooting efforts associated with them as well as the time they take to establish For example, to establish an SVC, you ll need to build a manual resolution table for each network layer protocol that is used between your router and the remote router If you are running IP, IPX, and AppleTalk, you ll need to configure all three of these entries in your resolution table Basically, your resolution table maps the remote s network layer address to its SVC address Depending on the number of protocols that you are running and the number of sites to which you are connecting, this process can take a lot of time And when you experience problems with SVCs, they become more difficult to troubleshoot because of the extra configuration involved on your side as well as the layer 2 routing table used on the carrier s side Setting up PVCs is actually much easier Plus, each time an SVC doesn t exist to a remote site, your router has to establish one, and it has to wait for the carrier switch to complete this process before your router can start sending its information to the destination Even though Frame Relay is a much more cost-effective solution than a dedicated circuit, it is slowly being replaced by other options, such as VPNs using the Internet via DSL and cable modem connections However, for delaysensitive traffic such as voice and video, a private network such as Frame Relay or ATM is used; even so, these two private network technologies are being supplanted by multiprotocol label switching (MPLS) across Ethernet or ATM in carrier networks

When compared to HDLC and PPP, Frame Relay is much more complex in operation, and many more terms are used to describe its components and operation Table 26-1 contains an overview of these terms Only the configuration of LMI is discussed in this book the configuration of other parameters, such as BC and BE, is beyond the scope of this book The proceeding sections describe the operation of Frame Relay and cover these terms in more depth
