DHCP also supports a mix of static and dynamic IP addresses In some systems, the device’s IP address can even change while it is still connected. With dynamic addressing, a device can have a different IP address every time it connects to the network. a Dynamic Host Configuration Protocol (DHCP) test verifies that the customer premises equipment (CPE) can obtain a valid IP address.a link check confirms that a link is active and can successfully negotiate a speed and duplex setting.Whether a new or existing customer orders a new circuit, field technicians must perform basic connectivity and service verification tests to ensure that the circuit is operational before it is turned up. Test equipment portability becomes a requirement and has driven the near replacement of all chassis-based test sets with new, affordable handheld devices.īasic connectivity testing and service verification This requires field technicians to accurately and efficiently conduct basic connectivity testing and service verification tests as well as performance testing and QoS testing. Today, carriers and service providers face tremendous competitive pressures and are driven to provision circuits with unprecedented speed and cost-efficiencies while still ensuring that service meets or exceeds the service-level agreement (SLA). Subscribers with different bandwidth profiles are provided with different levels of service. Any traffic sent beyond the excess rate is discarded. Service frames up to the committed rate are considered in-profile and delivered per the performance objectives frames sent up to the excess rate are allowed into the provider’s network but considered out-of-profile and delivered without service performance objectives. Each traffic profile consists of committed information rate, committed burst size, excess information rate, and excess information size. It specifies the average rate of “committed” and “excess” traffic that a subscriber can generate into the provider’s network and the associated performance objectives in terms of the delay, frame loss, and availability. The Metro Ethernet Forum (MEF) uses the concept of a bandwidth profile to describe the subscriber’s traffic. Roots may be growing into the cable buried in your yard.Concurrently, Ethernet has matured to support quality-of-service (QoS) parameters across multimedia traffic in a converged network. Speed may be slow because you’re using the internet at peak times, or your router may be outdated. You may even see disclaimers like “wireless speeds may vary” because Wi-Fi speeds are always inconsistent no matter what provider you choose-it’s just how Wi-Fi works.įor example, there may be issues with the provider’s service area, like faulty connections somewhere within the neighborhood. Internet providers will state “up to” when advertising maximum speeds because many variables can prevent you from hitting that top speed. What you see on the speed test is simply where your internet speeds are currently. Most of the time, your internet speeds will fluctuate within a small range of that max speed. The speeds promised by your internet plan are the max speeds you can expect. You likely won’t ever see the maximum speed advertised by your provider in the speed test, but your speed test results should come close. Why doesn’t my internet speed match my plan?
