摘要： Various technologies related to multi-path communications in a data center environment are described herein. Network infrastructure devices communicate traffic flows amongst one another, wherein a traffic flow includes a plurality of data packets intended for a particular recipient computing device that are desirably transmitted and received in a certain sequence. Indications that data packets in the traffic flow have been received outside of the certain sequence are processed in a manner to prevent a network infrastructure device from retransmitting a particular data packet.

摘要： A cloud computing environment providing a network service for a client computing entity. The network service is not an application level service, but rather a service that operates at or below the network layer in the protocol stack. For instance, the network service might be a network endpoint service such as a network address service (such as DNS) or a dynamic network service (such as DHCP), or a network traffic service such as a firewall service or a secure tunneling service (such as VPN). The service might also provide a pipeline of network services for network level traffic to and from the client computing entity. The cloud environment uses policy to determine which of a plurality of communication channels to use when exchanging cloud service data for the network service.
摘要翻译：为客户端计算实体提供网络服务的云计算环境。网络服务不是应用级服务，而是在协议栈中的网络层之下或之下运行的服务。例如，网络服务可以是诸如网络地址服务（例如DNS）或动态网络服务（例如DHCP）的网络端点服务，或诸如防火墙服务或安全隧道服务的网络流量服务（如VPN）。该服务还可以为客户计算实体的网络流量提供网络服务流水线。云环境使用策略来确定在为网络服务交换云服务数据时使用多个通信信道中的哪一个。

摘要： An intelligent lookup service for a network is provided for clients of a network requesting services of the network that intelligently determines, based on a service requirement of the requested service, optimal service endpoint(s) for providing the requested service. The intelligent lookup service can incorporate predetermined mapping policy and traffic measurements into the determination. In addition, a feedback loop is provided from clients and/or service endpoints to the lookup service concerning measurements about prior connections in the network. The lookup service can include a set of beacons distributed in the network and against which measurements about the network are recorded. A client receives, from the lookup service in response to a request for a network address, a set of candidate service endpoints that pertain to the requested network address and the client connects to one of the candidate service endpoints based on policy or context.

摘要： Routing network traffic on a computer network is described. In one embodiment, a method is presented which includes transmitting instructions to a client, the instructions executable by the client to request content from two or more content servers, measure two or more network performance characteristics associated with the two or more different content servers, and issue a report to an administrative server. The report may include a first network performance characteristic and a second network performance characteristic. The method may further include selecting a target content server from one of two or more content servers based on comparison of the two or more network performance characteristics; and transmitting routing instructions to an intermediate routing system, the routing instructions executable by the intermediate routing system to direct subsequent content requests transmitted by the client to the target content server.

摘要： Because it is difficult to provide adequate quality of service to large-bandwidth calls in integrated-services networks, service providers may allow some customers to book ahead their calls. The present invention provides a scheme resource sharing among book-ahead calls (that announce their call initiation and holding times upon arrival) and non-book-ahead calls (that do not announce their holding times and enter service immediately, if admitted). The basis for this sharing is an admission control algorithm in which admission is allowed if an approximate interrupt probability (computed in real time) is below a threshold. Simulation experiments show that the proposed admission control methodology is superior to alternative schemes that do not allow interruption, such as a strict partitioning of resources.
摘要翻译：由于难以为集成服务网络中的大带宽呼叫提供足够的服务质量，因此服务提供商可能会允许一些客户提前预订电话。本发明提供了在提前呼叫（其到达之后宣布呼叫启动和保持时间）和非预提呼叫（如果被允许的情况下不公布其保持时间并立即进入服务）的方案资源共享。该共享的基础是允许控制算法，其中如果近似中断概率（实时计算）低于阈值，则允许准入。仿真实验表明，所提出的准入控制方法优于不允许中断的替代方案，如严格划分资源。
