摘要： A method of enabling an electronic privately addressable source to be publicly addressable starts at a receiver where an electronic message is received. It is communicated from a sender with a private address outside a subnet of the receiver through a translator. The translator retrieves a lease to at least one of a public address or a port from a lease manager, translates the private address and the private port into a public address and a public port and communicates identifying data such as the public address and the public port to the receiver. If a response is communicated to the private sender, the response may be communicated to the private sender through the network. The public address and the public port on the message may be translated to the private address and the port of the private sender and the private address and the private port may be used to properly route the response to the private sender.

摘要： An embodiment of the invention is directed to reducing search-response latency. The closest intermediate server can be located between a client computing device and a search engine. A search query is sent to the intermediate server in a first packet of a transport protocol handshake. A plurality of packets are received from the intermediate server. The plurality of packets are used to open a window associated with a transport protocol. A response related to the search query is received by the client.

摘要： The subject disclosure is directed towards a technology that automatically mitigates datacenter failures, instead of relying on human intervention to diagnose and repair the network. Via a mitigation pipeline, when a network failure is detected, a candidate set of components that are likely to be the cause of the failure is identified, with mitigation actions iteratively targeting each component to attempt to alleviate the problem. The impact to the network is estimated to ensure that the redundancy present in the network will be able to handle the mitigation action without adverse disruption to the network.

摘要： The present application relates to network configurations and specifically to scalable load balancing network configurations. One implementation includes an external client coupled to a scalable load balancing system. The scalable load balancing system includes a load balancing layer that is configured to encapsulate individual incoming packets of a packet flow from the external client. The load balancing layer is further configured to route the incoming packets to target devices on the system. The target devices can span multiple IP subnets. The incoming packets can pass through one or more load balancers of the load balancing layer before reaching individual target devices. Individual target devices can be configured to route at least some outgoing packets of the packet flow to the external client without passing through any of the one or more load balancers.

摘要： Today, data networks are ever increasing in size and complexity. For example, a datacenter may comprise hundreds of thousands of service endpoints configured to perform work. To reduce network wide degradation, a load balancer may send work requests to healthy service endpoints, as opposed to unhealthy and/or inoperative service endpoints. Accordingly, among other things, one or more systems and/or techniques for monitoring service endpoints, which may be scalable for large scale networks, are provided. In particular, a consistent hash function may be performed to generate a monitoring scheme comprising assignments of service endpoints to monitoring groups. In this way, multiple monitoring components may monitor a subset of endpoints to ascertain health status. Additionally, the monitoring components may communicate between one another so that a monitoring component may know heath statuses of service endpoints both assigned and not assigned to the monitoring component.

摘要翻译： 今天，数据网络的规模和复杂性日益增加。 例如，数据中心可以包括被配置为执行工作的数十万个服务端点。 为了减少网络范围的恶化，负载平衡器可能会向健康的服务端点发送工作请求，而不是不健康和/或不工作的服务端点。 因此，提供了一种或多种用于监视服务端点的系统和/或技术，其可以对于大规模网络是可扩展的。 特别地，可以执行一致的散列函数以生成包括将服务端点分配给监视组的监视方案。 以这种方式，多个监视组件可以监视端点的子集以确定健康状况。 此外，监视组件可以彼此通信，使得监视组件可以知道既分配又未分配给监控组件的服务端点的健康状态。

摘要： Architecture that facilitates the capture of connection state of a connection established between a client and an intermediate server and forwards the state to one or more target servers. A software component at the target server (as well as the intermediate server) uses this connection state to reply back to the client directly, thereby bypassing the intermediate server. All packets from the client related to the request are received at the intermediate server and then forwarded to the target server. The migration can be accomplished without any change in the client operating system and client applications, without assistance from a gateway device such as a load balancer or the network, without duplication of all packets between the multiple servers, and without changes to the transport layer stack of the intermediate and target servers.

摘要： Techniques are described for balancing traffic load for networks configured in multi-rooted tree topologies, in the presence of link failures. Maximum flows (through minimum cuts) are calculated for subgraphs that incorporate effective link capacities on links between source and destination nodes. Effective link capacities may be determined that take into account link failures, as well as sharing of current available link capacities by multiple nodes. Traffic is balanced while simultaneously fully utilizing available link capacities, even available link capacities on partially failed links (e.g., partially failed Link Aggregation Groups (LAGs)).
