Patent ID: 7583617

Claim:
A method for forming a communications network using routers, the method comprising: a. analyzing a router location to determine if the router location is Virtual Private Network (VPN) resource constrained or interface constrained; b. if the router location is interface constrained, forming an interface constrained router network, comprising: i. a group of routers numbering at most [Q*] wherein [Q*] represents a number of routers that is used by a defined group of customers so that VPN resources will not be exhausted faster than interface resources for the group of routers, wherein [Q*] is determined by dividing a quantity of VPN resources available from a router [R] by an average amount of VPN resources averaged over a defined group of customers [F] forming a value [VR], and then dividing a quantity of interfaces available from a router in a group of routers [B] by an average number of interfaces[P] averaged over the defined group of customers forming [IR], and then dividing [VR] by [IR], where [Q*] equals [VR] divided by [IR]; ii. distributing customer connections for the defined group of customers over the group of routers numbering at most [Q*] using a round robin connectivity methodology; and iii. saving in a database information on each connected customer; and c. if the router location is not interface constrained, forming a VPN resource constrained router network.
