Abstract

One or more devices in a provider network receive provisioning information to migrate customer devices within a customer network from an original session border controller (SBC) device of the provider network to a new SBC device, where the provisioning information includes one or more fully-qualified domain names (FQDNs) associated with the original SBC device. The one or more devices update DNS server entries for the one or more FQDNs with an Internet Protocol (IP) address associated with the new SBC device and provide, to the customer devices within the customer network, DNS entry updates for the one or more FQDNs. The new SBC device then receives SIP session signal from the customer devices, and the configuration information associated with the customer may be deleted from the original SBC.

Claims

1. A method performed by one or more devices in a provider network, the method comprising:

receiving, at a new session border controller (SBC) device, provisioning information to migrate customer devices within a customer network from an original SBC device of the provider network to the new SBC device, where the provisioning information includes one or more fully-qualified domain names (FQDNs) associated with the original SBC device;

updating DNS server entries for the one or more FQDNs with an Internet Protocol (IP) address associated with the new SBC device;

providing, by a DNS server and to the customer devices within the customer network, DNS entry updates for the one or more FQDNs; and

receiving, by the new SBC device, a SIP session signal from the customer devices.

2. The method of claim 1, further comprising:

deleting, from the original SBC device, configuration information associated with the customer devices.

3. The method of claim 1, where the DNS server is included within the new SBC device.

4. The method of claim 1, further comprising:

providing, to the customer device, an new IP address for the DNS server.

5. The method of claim 4, where providing the new IP address for the DNS server includes:

sending, by the original SBC device and to a dynamic host configuration protocol (DHCP) server in the customer network, configuration information, for the customer devices, to change an IP address associated with a DNS server of the original SBC device to an IP address associated with a DNS server of the new SBC device.

6. The method of claim 5, further comprising:

sending, to the original session border controller and from a provisioning server within the provider network, the configuration information, for the customer devices, to change the IP address associated with the DNS server of the original SBC device to the IP address associated with a DNS server of the new SBC device.

7. The method of claim 1, further comprising:

providing, by a DNS server and to a proxy server within the provider network, DNS entry updates for the one or more FQDNs; and

receiving a SIP session signal from the proxy server.

8. The method of claim 1, further comprising:

sending, to the new SBC device and from a provisioning server within the provider network, the one or more FQDNs associated with the original SBC device.

9. A session border controller (SBC) device, comprising:

a memory to store instructions; and

a processor to execute the instructions to;

receive one or more fully-qualified domain names (FQDNs) associated with an original SBC device;

update DNS server entries for the one or more FQDNs with an Internet Protocol (IP) address associated with the SBC device;

provide the updated DNS server entries to one or more customer premises equipment (CPE) devices within a customer network; and

receive a SIP session signal from one of the one or more CPE devices.

10. The system of claim 9, where the processor is further to:

provide the updated DNS server entries to one or more proxy servers within a provider network; and

receive a SIP session signal from the proxy server.

11. The system of claim 9, where the one or more FQDNs associated with the original SBC device are received from a provisioning server via a network interface.

12. The system of claim 9, where the processor is further to:

receive translation rules the FQDNs associated with the original SBC device.

13. The system of claim 9, where the processor is further to:

update the DNS server entries for the one or more FQDNs with ports associated with the SBC device.

14. A system, comprising:

an original session border controller (SBC) device that includes one or more fully-qualified domain names (FQDNs) associated with the original SBC device; and

a new SBC device, where the new SBC is to;

receive the one or more FQDNs associated with the original SBC device,

associate DNS server entries for the one or more FQDNs with an Internet Protocol (IP) address for with the new SBC device,

send the DNS server entries to one or more customer premises equipment (CPE) devices within a customer network, and

receive a SIP session signal from one of the one or more CPE devices.

15. The system of claim 14, further comprising:

a provisioning server to provide, to the new SBC, the one or more FQDNs associated with the original SBC device.

16. The system of claim 14, where the original SBC is further to:

send configuration information, to a dynamic host configuration protocol (DHCP) server in the customer network, instructing the one or more CPE devices to change an IP address associated with a DNS server of the original SBC device to an IP address associated with a DNS server of the SBC device.

17. The system of claim 16, further comprising:

a provisioning server to provide, to the original SBC, the configuration information for the DHCP server in the customer network.

18. The system of claim 14, where the new SBC includes a DNS server component and where the original SBC includes a dynamic host configuration protocol (DHCP) server component.

19. A system, comprising:

one or more devices included within a provider network, the one or more devices comprising;

means for receiving provisioning information to migrate one or more customer devices within a customer network from an original SBC device of the provider network to a new SBC device, where the provisioning information includes one or more fully-qualified domain names (FQDNs) associated with the original SBC device;

means for updating DNS server entries for the one or more FQDNs with an Internet Protocol (IP) address associated with the new SBC device;

means for providing, to the customer devices within the customer network, DNS entry updates for the one or more FQDNs;

means for receiving a SIP session signal from the customer devices; and

means for deleting, from the original SBC device, configuration information associated with the customer devices.

20. The system of claim 19, where the one or more devices included within a provider network, further comprises:

means for providing, to a proxy server within the provider network, DNS entry updates for the one or more FQDNs.
