Likewise, you can use Traceroute (shown above) to ping every router along the route from the
QVDEC4K to the IP or DNS address you specify. Traceroute is very helpful in locating instances
where an ISP might employ dynamic load balancing and other routing problems that can affect the
quality of the video transport. Dynamic Load Balancing occurs where an ISP might specify an
alternate route to send packets to balance the load across its network. This is fine for web pages
that use TCP and can tolerate random delays. However, this can cause the packets within a video
stream to become mis-ordered, jumbling the video content. Using the Jitter Buffer in the QVidium
decoder or ARQ software can often restore correct packet order and stream integrity, at the cost of
