Sangwan
uses intelligent end-user routing software
called Border Gateway Protocol (BGP) between
there OC-3's. BGP identifies which path is the
most efficient for each data packet and then
routes the packet to its destination on the
fastest path. This increases the speed at which
web pages sent from our NOC arrive at their
destination. The network we use is connected via
OC-Level fiber connections to Verizon & Cambrian,
as well as gigabit fiber from PPL Telcom, and
Commonwealth Telephone. The network utilizes
100MBPS Gigabit Fiber from Global Crossing
(http://www.glbx.com), and 100MBPS Metro Fast
Ethernet drops from Level3
(http://www.level3.com), XO Communications
(http://www.xo.com), MFN/AboveNET (http://www.mfn.com),
Verio (http://www.verio.com), & Cogent (http://www.cogentco.com).
We currently use the only major data center
facility within 60-75 miles of the Tier-3
Scranton/Wilkes-Barre PA USA Metro Area. For
redundancy, we are currently running BGP4 to
maintain the speed and uptime. If one backbone
line goes down, it will balance the load to the
other(s). If one line gets congested, it will load
balance the traffic. Since our use of Cogent has
so much capacity, your data does not encounter the
"traffic jams" caused by so many other ISPs that
overload their networks with more subscribers than
they can handle. Cogent's dedicated bandwidth is
unmatched by any other carrier.
Studies
have shown that the most common reason for
downtime is circuit failure on Tier 1 provider
backbones, the major data highways. To guard
against this potential problem, we have two
Tier-1 providers. If one experiences problems,
we can route traffic down another one.
Furthermore, because we are OnNet with Level(3)
and Qwest, we share their digital distribution
architecture, which includes private peering
network connections to major Internet carriers
such as MCI, Sprint, UUNET, EUNET, AT&T,
AOL, Best, Erols, @Home, IBM Advantis and
others. These private peering arrangements allow
us to quickly and efficiently exchange packets
of data with every major backbone carrier in a
one-to-one environment.
Our
Network Operations Center uses industry-standard
SNMP (Simple Network Management Protocol) and
provides round-the-clock monitoring of all
hardware, including routers, switches, UPS
systems, and servers. The Network Operations
Center also monitors power, environmental
factors (such as temperature and humidity),
generator status, and network connectivity. All
critical services/ports can be monitored,
including FTP, HTTP, SMTP, HTTPS, SSH, TELNET,
and POP3. We provide network monitoring of the
Local Area Network, Internet connectivity (all
routers, switches, and wiring), and the Internet
backbone via MRTG. Our close and constant
communication with our upstream backbone
providers ensures that our customers have
constant access to high-performance Internet
connections. Failure on any monitoring service
results in audible alarms, LAN messages, and
alerting our staff paging system. We offer
remote cold boot hardware for dedicated server
clients, with private, password protected, web
based access.
Our Network Operations Center
utilizes ONLY top name brand hardware. The network is centered on a Cisco
GSR12000 Border Routers, and Cisco 7206VXR Core Routers, connecting via Gigabit
Ethernet to the Hewlett Packard Procurve 4108GL & Cisco Catalyst primary
switches. Hewlett Packard Procurve managed switches comprise the power and
stability of the network, operating at 100mbps switched Ethernet speeds.
Hardware utilized in the facility is comprised of name brands, including the
following: Intel, Asus, Abit, AMD, 3Com, Hewlett Packard, Adaptec, Cisco, Tekram,
Kingston, Micron, Crucial, IBM, Maxtor, Western-Digital, Seagate, Quantum,
Fujitsu, Realtec, Belkin, & Lucent. APC, Tripp-Lite, Compaq, & Liebert UPS
Systems provide the power backups, along with a Cummins generator system.
Facility monitoring is provided by a Digital Video System with CCTV cameras.
