Abstract

A network includes a provider edge device with logic to encapsulate Ethernet frames received from customer equipment into Data Over Cable Service Interface Specification (DOCSIS) frames using Layer Two Tunneling Protocol. The provider edge device further includes logic to implement a virtual switch instance (VSI).

Claims (17)

1. A network comprising: a provider edge device comprising machine memory and/or non-transitory machine readable media comprising logic to encapsulate Ethernet frames received from customer equipment into Data Over Cable Service Interface Specification (DOCSIS) frames using Layer Two Tunneling Protocol, and further comprising virtual switch instance logic (VSI); and the machine memory and/or the non-transitory machine readable media comprising logic to map customer edge (CE) and L2TP traffic types into DOCSIS classifiers and service flows by placing CE802.1P/Q packet fields into L2TP tunnels, and to add another 802.1P/Q packet to the outside of specified L2TP packets.

2. The network of claim 1 , wherein the VSI logic further comprises:

logic to perform basic switching.

3. The network of claim 1 , wherein the VSI logic further comprises:

logic to perform Media Access Control (MAC) address learning.

4. The network of claim 1 , wherein the VSI logic further comprises:

logic to perform flooding of unknown frames.

5. The network of claim 1 , wherein the VSI logic further comprises:

logic to perform traffic replication.

6. The network of claim 1 , wherein the VSI logic further comprises:

logic to perform aging of MAC addresses.

7. The network of claim 1 , wherein the provider edge device further comprises logic to define Ethernet port-to-port mapping.

8. The network of claim 1 , wherein the provider edge device further comprises logic to define connections defined by VLAN type.

9. The network of claim 1 , wherein the provider edge device further comprises logic to define Ethernet point-to-multipoint pseudowire.

10. The network of claim 1 , wherein the provider edge device further comprises logic to route Ethernet frames to multiple separate physical ports.

11. The network of claim 1 , wherein the VSI logic further comprises logic to emulate an Ethernet bridge.

12. The network of claim 1 , wherein the provider edge device further comprises logic to define Ethernet a multipoint-to-multipoint pseudowire.
