A network device can include packet processing circuitry to provide support for virtual functions. The packet processing circuitry can perform operations such as receiving data traffic from a virtual machine, determining an egress rule for the data traffic based on a rule table, and encapsulating the data traffic according to the egress rule.

Frameworks and interfaces for offload device-based packet processing

Generally described, systems and methods are provided for monitoring and detecting causes of failures of network paths. The system collects performance information from a plurality of nodes and links in a network, aggregates the collected performance information across paths in the network, processes the aggregated performance information for detecting failures on the paths, analyzes each of the detected failures to determine at least one root cause, and initiates a remedial workflow for the at least one root cause determined. In some aspects, processing the aggregated information may include performing a statistical regression analysis or otherwise solving a set of equations for the performance indications on each of a plurality of paths. In another aspect, the system may also include an interface which makes available for display one or more of the network topology, the collected and aggregated performance information, and indications of the detected failures in the topology.

Monitoring and detecting causes of failures of network paths

A network device can include packet processing circuitry to provide support for virtual functions. The packet processing circuitry can perform operations such as receiving data traffic associated with a physical address, determining that the data traffic is associated with a guest of a host system by matching the data traffic with an ingress rule associated with a virtual function, and forwarding the data traffic to the virtual function.

High-speed processing of packets to, and from, a virtualization environment can be provided while utilizing hardware-based segmentation offload and other such functionality. A hardware vendor such as a network interface card (NIC) manufacturer can enable the hardware to support open and proprietary stateless tunneling in conjunction with a protocol such as single root I/O virtualization (SR-IOV) in order to implement a virtualized overlay network. The hardware can utilize various rules, for example, that can be used by the NIC to perform certain actions, such as to encapsulate egress packets and decapsulate packets.

The transmission of data on computer networks according to one or more policies is disclosed. A policy may specify, among other things, various parameters which are to be followed when transmitting initiating network traffic. Multiple network interfaces may be installed on a server to enable transmission of data from the single server according a number of discrete configuration settings implicated by the various policies. The multiple network interfaces may correspond to separate physical components, with each component configured independently to implement a feature of a policy. The multiple network interfaces may also correspond to a single physical component that exposes multiple network interfaces, both to the network and to the server on which it is installed.

Network policy implementation with multiple interfaces

A system and method for message analysis, including: receiving, by a control service, a first modification request to modify a file system of a computing device, wherein the computing device is operating in a read-only state; identifying, by the control service, a request parameter associated with the first modification request; determining, by the control service, that the request parameter satisfies a permission criteria to perform the first modification request; provisioning, by the control service, the computing device to operate in a read/write state in response to determining that the permission criteria has been satisfied, wherein the first modification request is executed to modify the file system while the computing device is operating in the read/write state; and, upon a determination that the first modification request has successfully completed, provisioning, by the control service, the computing device to operate in the read-only state.

File system modification

Methods and apparatus for a bandwidth pool pricing service are disclosed. A system includes a plurality of resources of a provider network and a resource manager. The resource manager implements a programmatic interface allowing a client to choose among several supported bandwidth pricing policies for a resource group allocated to the client. One pricing policy includes a first pricing component based on an intra-group network traffic rate, and a second pricing component based on an extra-group network traffic rate. If the client selects the policy, the resource manager provides billing amounts to the client derived from the first and second pricing components and from a set of collected network traffic metrics.

Resource group traffic rate service

Operating profiles for consumers of computing resources may be automatically determined based on an analysis of actual resource usage measurements and other operating metrics. Measurements may be taken while a consumer, such as a virtual machine instance, uses computing resources, such as those provided by a host. A profile may be dynamically determined based on those measurements. Profiles may be generalized such that groups of consumers with similar usage profiles are associated with a single profile. Assignment decisions may be made based on the profiles, and computing resources may be reallocated or oversubscribed if the profiles indicate that the consumers are unlikely to fully utilize the resources reserved for them. Oversubscribed resources may be monitored, and consumers may be transferred to different resource providers if contention for resources is too high.

Automated profiling of resource usage

A set of techniques is described for monitoring and analyzing crashes and other malfunctions in a multi-tenant computing environment (e.g. cloud computing environment). The computing environment may host many applications that are executed on different computing resource combinations. The combinations may include varying types and versions of hardware or software resources. A monitoring service is deployed to gather statistical data about the failures occurring in the computing environment. The statistical data is then analyzed to identify abnormally high failure patterns. The failure patterns may be associated with particular computing resource combinations being used to execute particular types of applications. Based on these failure patterns, suggestions can be issued to a user to execute the application using a different computing resource combination. Alternatively, the failure patterns may be used to modify or update the various resources in order to correct the potential malfunctions caused by the resource.
