| 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.
