A Private Network Access Point (PNAP) packet switched network is provided where two customers connected to the same PNAP exchange traffic through the PNAP without transiting over the backbones of the Internet. In addition, a multi-homed customer connected to the PNAP is provided with access to the PNAP optimized routing table so that the customer will also have the ability to know the best route for a particular destination. In this way, if a multi-homed customer connected to a particular National Service Provider (NSP) to which a destination is also connected, the PNAP customer can use the PNAP information regarding the NSP to send the information to the destination through that commonly connected NSP in the most direct fashion.

A network as recited in claim 1, wherein said PNAP routing infrastructure lists a direct connection between said first and second customers within said customer side of the PNAP, and wherein said PNAP routing infrastructure sets the level of preference higher for said direct connection than for any other routes between said first and second customers.4. A packet-switched network, comprising:a Private Network Access Point (PNAP) having a customer side and a service provider side; at least a first customer and a second customer connected to the customer side of the PNAP; a plurality of service providers connected to the service provider side of the PNAP; and an interconnected network system connected to said plurality of service providers and to said first and second customers; wherein a PNAP routing infrastructure within said PNAP contains a routing table listing a plurality of routes to a plurality of destinations in the network, along with a parameter indicating a degree of preference attached to each route; wherein said PNAP routing infrastructure lists a direct connection between said first and second customers within said customer side of the PNAP; wherein said first customer is connected to a service provider who is also connected to the service provider side of the PNAP so that said first customer is multi-homed; wherein said multi-homed customer is provided with said routing table along with a community attribute denoting a preferred reachability of a given route through the connection to the service provider; and wherein said multi-homed customer can utilize ASimilater data received over a Border Gateway Protocol (BGP) feed from the PNAP and send traffic to a destination served by said service provider through said multi-homed customer's connection to said service provider by using said routing table to set route preferences in a router maintained by said multi-homed customer. 5. A network as recited in claim 4, wherein said PNAP routing infrastructure sets the level of preference higher for said direct connection than for any other routes between said first and second customers.6. A network as recited in claim 4, wherein traffic between said first and second customers is exchanged through the PNAP without transiting over said service provider.7. A method for exchanging traffic in a packet-switched network, comprising:providing a Private Network Access Point (PNAP) having a customer side and a service provider side, wherein at least a first customer and a second customer are connected to the customer side and at least one service provider is connected to the service provider side, wherein the first customer, the second customer and the service provider are connected to an interconnected network system, and wherein said first customer is connected to a service provider who is also connected to the service provider side of the PNAP so that said first customer is multi-homed; providing said multi-homed customer with a routing table listing a plurality of routes to a plurality of destinations in the network, along with a community attribute denoting a preferred reachability of a given route through the connection to the service provider: allowing said multi-homed customer to utilize ASimilater data received over a Border Gateway Protocol (BGP) feed from the PNAP and send traffic to a destination served by said service provider through said multi-homed customer's connection to said service provider by using said routing table to set route preferences in a router maintained by said multi-homed customer; and causing traffic between said first and second customers to be exchanged through the PNAP without transiting over said service provider. 8. A method as recited in claim 7, wherein a PNAP routing infrastructure within said PNAP contains a routing table listing a plurality of routes to a plurality of destinations in the network, along with a parameter indicating a degree of preference attached to each route.9.
