Expandability is limited Currently, the MPLS vendor's Control Plane and Forwarding Information Base (FIB) forms appear to be reaching the upper limit of the extension, which causes the provider to have to control the number of routes received from the customer. For businesses, this means an increase in risk and an increased risk of a decline in the number of routes. In addition, the constant adjustment and maintenance of hardware caused by the increasing demand for supplier edge equipment (PE) and backbone capacity will put service providers under cost pressure. In an increasingly WAN environment, service quality is affected, and the WAN has no application awareness yet, and there is no ability to differentiate between different application performance thresholds. At the same time, software failure/partial power failure can have a catastrophic effect on real-time applications. Whether it is time delay, data loss or the number of monthly outages, it requires a huge management fee. Although procurement teams and corporate service owners are valued in negotiating a specific SLA for penalties, these violations often have a very serious impact on the business. Maintenance of service providers sometimes lacks coordination, which has an unintended effect on the business. The time to detect failures and recover services is often very long. Fault detection needs to be synchronized between the service provider control layer and the polygon client control layer (control layer bifurcation point). Although users can adjust the boundary timer, they still rely on the vendor's backbone to detect, control, revoke, and stop the upgrade. This situation also occurs in the dual-operator MPLS architecture. Read More; https://www.fieldengineer.com/sd-wan/top-11-telecom-companies |
