The techniques may be applied to determine, or “trace,” a physical network path in the virtualized network domain. In some examples, a network device includes one or more processors and a switch executed by the processors to forward packets of a packet flow to a physical network path. The network device also includes a flow trace module to generate one or more flow trace packets having incrementally increasing respective time-to-live (TTL) values, wherein the switch module forwards the flow trace packets on an outbound interface of the network device for the physical network path, and wherein the flow trace module receives corresponding time exceeded messages for the flow trace packets, wherein each of the time exceeded message includes a source network address of a network element on the physical network path.

Abstract: In general, techniques are described for dynamically modifying the extent of logging performed by logging information generators in response to events detected in logging information received by the collector. In some examples, a network device includes one or more processors and a collector executed by the processors to receive a log message that includes logging information from a generator. The network device also includes a rules engine to apply one or more rules that each specify a condition and a corresponding action to the logging information to identify a matching rule, wherein the rules engine, upon identifying a matching rule, executes the action of the matching rule to generate and send a logging modification message to increase an extent to which the generator generates logging information.

Abstract: In general, techniques are described for configuring and managing virtual networks. For example, a distributed virtual network controller is described that configures and manages an overlay network within a physical network formed by plurality of switches. A plurality of servers are interconnected by the switch fabric, each of the servers comprising an operating environment executing one or more virtual machines in communication via the overlay networks. The servers comprises a set of virtual switches that extends the overlay network as a virtual network to the operating environment of the virtual machines. The controller may instruct the servers and the virtual switches to perform various operations, such as determining a physical network path taken by packets of a network packet flow, determining latency through the network, re-routing traffic in the virtual network due to network events, replicating traffic for multicasting, providing multi-tenant services to support multiple virtual networks, monitoring and logging traffic characteristics within the virtual networks and other operations.

Abstract: In general, techniques are described for facilitating multi-tenancy of a server accessed by virtual networks of a data center. A device included within a data center comprising one or more processors may perform the techniques. The processors may be configured to execute a virtual switch that supports a number of virtual networks executing within the data center. The virtual switch may be configured to receive a request regarding data associated with an identifier that is unique within one of the virtual networks that originated the request. The virtual switch may then translate the identifier included within the request to generate a globally unique identifier that is unique within the plurality of virtual networks, update the request to replace the identifier included within the request with the globally unique identifier, and transmit the updated request to a server of the data center.
