Apparatus and methods for establishing virtual private networks in a broadband network
View Patent ↗Service providers can reduce multiple overlay networks by creating multiple logical service networks (LSNs) on the same physical or optical fiber network through use of an embodiment of the invention. The LSNs are established by the service provider and can be characterized by traffic type, bandwidth, delay, hop count, guaranteed information rates, and/or restoration priorities. Once established, the LSNs allow the service provider to deliver a variety of services to customers depending on a variety of factors, for example, a customer's traffic specifications. Different traffic specifications are serviced on different LSNs depending on each LSN's characteristics. Such LSNs, once built within a broadband network, can be customized and have its services sold to multiple customers.
1. A method for establishing logical service networks in a communications network, the method comprising:
assigning a unique customer identifier to each of multiple service locations for at least one customer registered for service at the multiple service locations; and
grouping the multiple service locations for the at least one customer and assigning a unique group identifier to associate the multiple service locations with the at least one customer in a logical service network in the communications network.
2. The method of claim 1 , further including establishing logical paths between the multiple service locations in the logical service network and associating the logical paths established to each other based on the unique group identifier assigned.
3. The method of claim 2 , wherein the logical paths established and the unique group identifier associated provide security guarantees.
4. The method of claim 1 , further including establishing logical paths between the multiple service locations in the logical service network, and wherein the logical paths established are unique to the at least one customer.
5. The method of claim 4 , further including policing the logical paths, wherein the logical paths are private Internet Protocol (IP) paths unique to the at least one customer.
6. The method of claim 1 further including configuring the logical service network according to one of a traffic type, bandwidth, delay, hop count, guaranteed information rate, and restoration priority.
7. The method of claim 1 , further including creating the logical service network according to inputs from a service provider.
8. The method of claim 1 , further including creating the logical service network automatically according to software execution.
9. The method of claim 1 , wherein the logical service network is a virtual private network (VPN), the unique customer identifier is a VPN label, and the unique group identifier is a VPN group label.
10. A system for establishing logical service networks in a communication network, the system comprising:
an assignment module configured to assign a unique customer identifier to each of multiple service locations for at least one customer registered for service at the multiple service locations; and
a grouping module configured to group the multiple service locations for the at least one customer and assigning a unique group identifier to associate the multiple service locations with the at least one customer in a logical service network in the communications network.
11. The system of claim 10 , further including an establishment module configured to establish logical paths between the multiple service locations in the logical service network and an association module configured to associate the logical paths established to each other based on the unique group identifier.
12. The system of claim 11 , wherein the logical paths established and the unique group identifier associated provide security guarantees.
13. The system of claim 10 , further including an establishment module configured to establish logical paths between the multiple service locations in the logical service network, and wherein the logical paths established are unique to the at least one customer.
14. The system of claim 13 , further including a policer configured to police the logical paths, wherein the logical paths are private Internet Protocol (IP) paths unique to the at least one customer.
15. The system of claim 10 further including a configuration module configured to configure the logical service network according to one of a traffic type, bandwidth, delay, hop count, guaranteed information rate, and restoration priority.
16. The system of claim 10 , further including a configuration module configured to create the logical service network according to inputs from a service provider.
17. The system of claim 10 , further including a configuration module configured to create the logical service network automatically according to software execution.
18. The system of claim 10 , wherein the logical service network is a virtual private network (VPN), the unique customer identifier is a VPN label, and the unique group identifier is a VPN group label.
19. A non-transitory computer-readable medium having stored thereon a sequence of instructions which, when loaded and executed by a processor, causes the processor to:
assign a unique customer identifier to each of multiple service locations for at least one customer registered for service at the multiple service locations; and
group the multiple service locations for the at least one customer and assigning a unique group identifier to associate the multiple service locations with the at least one customer in a logical service network in the communications network.
20. The non-transitory computer-readable medium of claim 19 wherein the sequence of instructions further causes the processor to establish logical paths between the multiple service locations in the logical service network and associate the logical paths established to each other based on the unique group identifier assigned.
