 Network
 Core Network:
Switch currently operates 6 NAP-IX data centers. All data centers are connected diversely and redundantly by Switch owned fiber. Every data center has multiple pathways to the other data centers to take advantage of a broad blend of five Internet transit providers. This design succeeds in being dynamic, robust, and diverse.
Customers who colocate in one of the NevadaNAPs are provided a number of different options for Internet connectivity. These range from single drops, to multiple redundant drops. Redundancy to the customer is provided either by BGP (Border Gateway Protocol) or HSRP (Hot Standby Routing Protocol).
 BGP A:
Example Customer Setup
BGP, Border Gateway Protocol, is currently the most appropriate routing protocol to be placed between different systems. In this example a firm demarcation is created between the systems while avoiding a single point of failure. Only a handful of routes need be exchanged between the systems keeping complexity at a minimum.
 HSRP A:
Example Customer Setup
HSRP, Hot Standby Routing Protocol, is a mechanism to provide a redundant gateway for connected devices. In this example, the redundant gateway is provided to all servers. This example still contains a single point of failure in the customer switch. Failure of this device will render the HSRP gateway inaccessible.
 HSRP B:
Example Customer Setup
A seemingly small but important distinction from example A, a router is placed behind the switch. This is an improvement as a demarcation is declared between the two systems.
 HSRP C:
Example Customer Setup
This example eliminates a single point of failure and promotes the greatest possible uptime. Additionally, HSRP, or equivalent, can be run across the switches from the customer routers to provide a redundant destination for Switch to route to.
 Single Connection A:
Example Customer Setup
This example eliminates a single point of failure and promotes the greatest possible uptime. Additionally, HSRP, or equivalent, can be run across the switches from the customer routers to provide a redundant destination for Switch to route to.
 Single Connection B:
Example Customer Setup
This example eliminates a single point of failure and promotes the greatest possible uptime. Additionally, HSRP, or equivalent, can be run across the switches from the customer routers to provide a redundant destination for Switch to route to.
