Abstract

Aspects of the subject disclosure may include, for example, a virtual network element that includes a plurality of virtual machine modules configured to process a plurality of control packets in a virtualized telecommunication network. A classifier module is configured to receive telecommunications traffic that includes the plurality of control packets and a plurality of data packets, to separate the plurality of control plane data from the at least one data packet, and to forward the plurality of control packets to selected ones of the plurality of virtual machine modules. A forwarding device, coupled to the classifier module and separate from the plurality of virtual machine modules, is configured to forward the plurality of data packets in the virtualized telecommunication network. Other embodiments are disclosed.

modifying, based on the updating data generated by the plurality of virtual machines, at least a portion of the plurality of data packets of the telecommunications traffic to generate modified data packets, wherein modifying at least the portion of the plurality of data packets comprises at least one of rewriting header information in at least one of the plurality of data packets based on the updating data, filtering out at least one of the plurality of data packets based on the updating data, or rate limiting at least one of the plurality of data packets based on the updating data, and
forwarding the modified data packets in the virtualized telecommunication network.

2. The virtual network element of claim 1 , wherein the updating data is generated further in accordance with packet forwarding rules.

3. The virtual network element of claim 1 , wherein the updating data is generated in accordance with at least one application programming interface that facilitates a communication channel between the plurality of virtual machines and the forwarding device.

4. The virtual network element of claim 1 , wherein the forwarding device includes a network packet switch.

5. The virtual network element of claim 1 , wherein the forwarding device operates in accordance with a data plane development kit.

6. The virtual network element of claim 1 , wherein the forwarding device receives the telecommunications traffic and forwards the telecommunications traffic to the computing device executing the classifier module.

7. A method comprising:

receiving, by the forwarding device, the plurality of data packets of the telecommunications traffic;
receiving, by the forwarding device, from the plurality of virtual machines, the updating data generated by the plurality of virtual machines, wherein the forwarding device is separate from the plurality of virtual machines;
modifying, by the forwarding device, based on the updating data generated by the plurality of virtual machines, at least a portion of the plurality of data packets of the telecommunications traffic to generate modified data packets, wherein modifying at least the portion of the plurality of data packets comprises at least one of rewriting header information in at least one of the plurality of data packets based on the updating data, filtering out at least one of the plurality of data packets based on the updating data, or rate limiting at least one of the plurality of data packets based on the updating data; and
forwarding, by the forwarding device, the modified data packets in the virtualized telecommunication network.

8. The method of claim 7 , wherein the forwarding device receives the telecommunications traffic and forwards the telecommunications traffic to the computing device executing the classifier module.

9. The method of claim 7 , wherein the updating data is generated further in accordance with at least one application programming interface that facilitates a communication channel between the plurality of virtual machines and the forwarding device.

10. The method of claim 7 , wherein the forwarding device executes in accordance with a data plane development kit.

11. The method of claim 7 , wherein the updating data is generated further in accordance with packet forwarding rules.

12. A virtual network element comprising:
