A third is SLAs. With options such as usage-based billing, secure connectivity, and resiliency capabilities such as rerouting, service providers can offer their customers numerous SLA guarantees. The flexibility with signaling destinations creates numerous options to meet customer needs. Voice, video and data calls can be made virtually anywhere, anytime, with high levels of QoS. SVCs also provide support for services such as videoconferencing through dynamic bandwidth allocation. This creates efficient use of trunks and simplified administration, creating new revenue sources for service providers.
Users also can save in areas such as travel budgets by utilizing teleconferencing capabilities.
With SVCs, users can take advantage of public network infrastructures for secure connections such as VPNs on an as-needed basis, often eliminating the need for private networks. Quality and Security SVCs now offer all of the QoS capabilities that private networks or PVCs provide. Because SVCs are dynamically established, it is essential that service providers be able to restrict SVCs to provide secure connections and guarantee paths for high priority traffic. For example, service providers can restrict the bandwidth allocated to SVCs on a logical port. They also can limit the bandwidth available to each of the established QoS classes, and maximum values of allowed traffic parameters can be set for each service class.
