Abstract
Techniques are described for communications in an L2 virtual network. In an example, the L2 virtual network includes a plurality of L2 compute instances hosted on a set of host machines and a plurality of L2 virtual network interfaces and L2 virtual switches hosted on a set of network virtualization devices. An L2 virtual network interface emulates an L2 port of the L2 virtual network. Span port information applicable to the L2 port is sent to a network virtualization device that hosts the L2 virtual network interface.
Claims20
A method comprising:
- hosting, by a network virtualization device, a Layer 2 virtual network interface and a Layer 2 virtual switch that belong to a Layer 2 virtual network of a customer, wherein:
- the Layer 2 virtual network interface and the Layer 2 virtual switch are associated with a Layer 2 compute instance that belongs to the Layer 2 virtual network,
- the Layer 2 compute instance is hosted on a host machine of a physical network that comprises the host machine and the network virtualization device,
- the host machine and the network virtualization device are separate physical devices that are communicatively coupled, and
- the Layer 2 virtual network is hosted on the physical network;
- receiving, by the network virtualization device, information from a control plane of the physical network, wherein the information indicates one or more criteria associated with copying frames and a destination to receive frame copies, wherein the information is based on a mapping of a customer-specified configuration of the Layer 2 virtual network and a topology of the Layer 2 virtual network;
- storing, by the network virtualization device, the information;
- receiving, by the network virtualization device, a frame comprising header information, wherein the frame is destined to or originates from the Layer 2 compute instance;
- determining, by the network virtualization device by comparing the header information with the one or more criteria, that the one or more criteria are satisfied for the frame;
- generating, by the network virtualization device, a copy of the frame;
- and
- sending, by the network virtualization device, the copy of the frame to the destination.

A network virtualization device comprising:
- one or more processors;
- and
- one or more computer-readable storage media storing instructions that, upon execution by the one or more processors, configure the network virtualization device to:
- host a Layer 2 virtual network interface and a Layer 2 virtual switch that belong to a Layer 2 virtual network of a customer, wherein:
- the Layer 2 virtual network interface and the Layer 2 virtual switch are associated with a Layer 2 compute instance that belongs to the Layer 2 virtual network,
- the Layer 2 compute instance is hosted on a host machine of a physical network that comprises the host machine and the network virtualization device, the host machine and the network virtualization device are separate physical devices that are communicatively coupled, and
- the Layer 2 virtual network is hosted on the physical network;
- receive information from a control plane of the physical network, wherein the information indicates one or more criteria associated with copying frames and a destination to receive frame copies, wherein the information is received based on a mapping of a customer-specified configuration of the Layer 2 virtual network and a topology of the Layer 2 virtual network;
- store the information;
- receive a frame comprising header information, wherein the frame is destined to or originates from the Layer 2 compute instance;
- determine, by comparing the header information with the one or more criteria, that the one or more criteria are satisfied for the frame;
- generate a copy of the frame;
- and
- send the copy of the frame to the destination.

A non-transitory computer-readable storage medium storing instructions that, upon execution by one or more processors of a network virtualization device, cause the one or more processors to perform operations comprising:
- hosting a Layer 2 virtual network interface and a Layer 2 virtual switch that belong to a Layer 2 virtual network of a customer, wherein:
- the Layer 2 virtual network interface and the Layer 2 virtual switch are associated with a Layer 2 compute instance that belongs to the Layer 2 virtual network,
- the Layer 2 compute instance is hosted on a host machine of a physical network that comprises the host machine and the network virtualization device,
- the host machine and the network virtualization device are separate physical devices that are communicatively coupled, and
- the Layer 2 virtual network is hosted on the physical network;
- receiving, by the network virtualization device, information from a control plane of the physical network, wherein the information indicates one or more criteria associated with copying frames and a destination to receive frame copies, wherein the information is based on a mapping of a customer-specified configuration of the Layer 2 virtual network and a topology of the Layer 2 virtual network;
- storing the information;
- receiving a frame comprising header information, wherein the frame is destined to or originates from the Layer 2 compute instance;
- determining, by comparing the header information with the one or more criteria, that the one or more criteria are satisfied for the frame;
- generating a copy of the frame;
- and
- sending the copy of the frame to the destination.
