Methods, systems, and products for voice-over internet protocol calls
Network resources for a call are allocated. The network resources for the call are reserved based on a reservation. The network resources are reserved before any one network resource is committed. If the call is confirmed, then the network resources are committed.
1. A method, comprising:
receiving, by a server, a request associated with a network resource;
reserving, by the server, a gate associated with the network resource, the gate for admitting packets of data associated with the request;
counting, by the server, a timer associated with the gate;
monitoring, by the server, for a receipt of an acknowledgment message during the counting of the timer, the acknowledgment message confirming the request;
establishing, by the server, the gate in response to the receipt of the acknowledgement message prior to an expiration of the timer; and
terminating, by the server, the gate in response to the expiration of the timer without the receipt of the acknowledgement message.
2. The method of claim 1 , further comprising comparing an Internet protocol address to a destination address associated with the gate.
3. The method of claim 1 , further comprising comparing an Internet protocol address to a source address associated with the gate.
4. The method of claim 1 , further comprising matching an Internet protocol address to an address associated with the gate.
5. The method of claim 1 , further comprising receiving a rejection associated with the network resource.
6. The method of claim 1 , further comprising filtering the packets of data.
7. The method of claim 1 , further comprising associating information in a header to the gate.
8. A system, comprising:
a processor; and
a memory device, the memory device storing instructions, the instructions when executed causing the processor to perform operations, the operations comprising:
receiving a request associated with a network resource;
reserving a gate associated with the network resource, the gate for admitting packets of data associated with the request;
counting a timer associated with the gate;
monitoring for a receipt of an acknowledgment message during the counting of the timer, the acknowledgment message confirming the request;
establishing the gate in response to the receipt of the acknowledgement message prior to an expiration of the timer; and
terminating the gate in response to the expiration of the timer without the receipt of the acknowledgement message.
9. The system of claim 8 , wherein the operations further comprise comparing an Internet protocol address to a destination address associated with the gate.
10. The system of claim 8 , wherein the operations further comprise comparing an Internet protocol address to a source address associated with the gate.
11. The system of claim 8 , wherein the operations further comprise matching an Internet protocol address to an address associated with the gate.
12. The system of claim 8 , wherein the operations further comprise receiving a rejection associated with the network resource.
13. The system of claim 8 , wherein the operations further comprise filtering the packets of data.
14. The system of claim 8 , wherein the operations further comprise associating information in a header to the gate.
15. A system, comprising:
a processor; and
a memory device, the memory device storing instructions, the instructions when executed causing the processor to perform operations, the operations comprising:
reserving a gate associated with a network resource, the gate for admitting packets of data associated with a call;
counting a timer associated with the gate;
monitoring for an acknowledgment message as the timer counts, the acknowledgment message confirming the call;
confirming the gate in response to a receipt of the acknowledgement message prior to an expiration of the timer; and
terminating the gate in response to the expiration of the timer without the receipt of the acknowledgement message.
16. The system of claim 15 , wherein the operations further comprise establishing the gate associated with a network edge device.
17. The system of claim 15 , wherein the operations further comprise establishing the gate associated with a router.
18. The system of claim 15 , wherein the operations further comprise establishing the gate associated with a server.
19. The system of claim 15 , wherein the operations further comprise comparing an Internet protocol address to a destination address associated with the gate.
20. The system of claim 15 , wherein the operations further comprise comparing an Internet protocol address to a source address associated with the gate.
