摘要:
A method includes receiving a packet from a first virtual machine (VM) in a distributed overlay virtual Ethernet (DOVE) network. A first virtual switch appends the packet with a tunnel header that is addressed for a second virtual switch. The first virtual switch acts as a virtual default gateway based on replacement of a first destination address for the virtual default gateway with a second destination address for a second VM. Multiple virtual gateways in the DOVE network share a same media access control (MAC) address.

In one embodiment, an apparatus includes a processor and logic integrated with and/or executable by the processor. The logic is configured to cause the processor to receive one or more packets to be switched to a next hop, the one or more packets indicating a destination address and a first virtual network identifier (VNID). The logic is also configured to cause the processor to send a query to a controller in order to determine a service chain for the one or more packets, the query including the first VNID and the destination address. Moreover, the logic is configured to cause the processor to receive a response that includes the next hop and a next routed hop for the one or more packets. Other systems, methods, and computer program products are described in accordance with more embodiments.

In one embodiment, a system includes a processor and logic integrated with and/or executable by the processor. The logic is configured to cause the processor to receive an overlay-encapsulated packet comprising one or more underlay packets. The logic is also configured to cause the processor to decapsulate the one or more underlay packets from the overlay-encapsulated packet. Moreover, the logic is configured to cause the processor to derive a priority for each of the one or more underlay packets based on a priority of the overlay-encapsulated packet, a transport header of the overlay-encapsulated packet, or the priority and the transport header of the overlay-encapsulated packet. In addition, the logic is configured to cause the processor to set the priority of the one or more underlay packets.

A method includes encapsulating, by a first virtual switch, a packet from a first virtual machine (VM) into a tunneled packet by appending the packet with a tunnel header that is addressed for a second virtual switch, wherein the packet includes a first destination address for a virtual default gateway. The first virtual switch forwards an inner packet of the encapsulated packet to a second VM. The first virtual switch acts as a virtual default gateway based on replacement of a first destination address for the virtual default gateway with a second destination address for the second VM.

Embodiments of the invention relate to providing acceleration for traffic migration for virtual machine (VM) migration in overlay networks. One embodiment includes a method that includes migrating of a VM from a first hypervisor to a second hypervisor. The first hypervisor detects incoming encapsulated traffic sent from a third hypervisor that is targeted for the VM. The first hypervisor indicates to a service of incorrect information in the incoming encapsulated traffic for the VM. The third hypervisor is notified with updated information for the VM.

In a distributed network environment, a first virtual machine sends a first virtual machine control information to a first network system. The first network system sends a first control information to a first network control system in response to receiving the first virtual machine control information. The first network control system sends a portion of the first control information to a number of network systems. The first network control system sends a second control information to the first network system. The first virtual machine sends a first packet to the first network system which generates a unicast packet using a portion of the first packet and a portion of the second control information. A second network system receives and processes the unicast packet. The second network system sends a copy of the processed unicast packet to a second virtual machine associated with a second tenant.

In one embodiment, an apparatus includes a processor and logic configured to designate one of a plurality of endpoint virtual network identifiers (EPVNIDs) for each endpoint device in a network, wherein each EPVNID is configured to be shared by one or more endpoint devices, designate a common waypoint virtual network identifier (WPVNID) for all transparent waypoint devices in the network which perform a same function, designate a unique WPVNID for each routed waypoint device in the network, designate a common virtual network identifier (VNID) for all virtual switches in a single virtual network, wherein a different VNID is designated for each virtual network, and create a service chain table comprising each VNID, WPVNID, and EPVNID designated in the network individually correlated with at least a pair of VNIDs: a source VNID and a destination VNID, based on one or more policies affecting application of services to packets in the network.
