Business
users should be aware however that there are great
differences between DSL service and Point to Point
dedicated lines (T1, Frame Relay, etc).
Most significant are covered by the terms SLA
and MTTR:
- SLA
(Service Level Agreement) - This is your guarantee
of service quality. Typical measures are latency,
or response time (measured in ping delay) and
packet delivery. Latency on IP traffic causes
delays in delivery or retransmission of segments
of data, and may vary throughout the day. On
the Qwest Network there are no guarantees on latency,
and performance will vary greatly throughout the
day.
- MTTR
(Mean Time to Repair) - This is the biggest
challenge to DSL, MTTR requirements. Qwest has
a target goal of (and typically meets) a maximum
restoration time of 4 hours for a point to point
dedicated line failure. DSL service (regardless
of provider) has an MTTR of 24 hours. Outages
on individual lines are treated with the same
level of urgency as a phone line outage.
Another
significant difference are differences in upstream/downstream
bandwidth. ADSL is Asnchronous, so that
the download speed is great, while the upload speed
can be a fraction of the download speed. Point to
point circuits are Synchronous, ie: speed is
the same both directions.
Still, we've done our best to ensure your connection
with us through Qwest is the best you can get in the
state. Our connection to Qwest is via a dedicated
DS3, transported to us from Qwest via our own SONET
OC3. That in turn connects to two diverse upstream
providers using BGP routing protocol. We never
oversell or oversubscribe our connections or bandwidth.
What
is the difference? Business customers have Fixed IP
addresses, monitoring and bandwidth guarantees with
direct routes to the Internet backbone. Residential/small
business customers will have dynamically allocated IPs
by default, no monitoring and no bandwidth guarantees
(just like any other provider). Residential users may
also be routed via a proxy gateway that stores locally
cached versions of the most popular sites on the internet.
This greatly speeds up access to those sites, but also
serves to reduce bandwidth load on our upstream connections.
