摘要： A content delivery system includes a cache server, a domain name server, and a redirector. The domain name server is configured to receive a request for a cache server address, and provide an IPv6 anycast address. The redirector is configured to receive a content request addressed to the IPv6 anycast address from a client system, receive load information from the cache server, and determine if the cache server is available. The redirector is further configured to forward the content request to the cache server when the cache server is available. The cache server is configured to receive the content request forwarded from the redirectors, send a response to the content request to a client system, the response including an IPv6 unicast address of the cache server as a source address, an IPv6 unicast address of the client system as a destination address, and the IPv6 anycast address as a home address, and provide the content to the requestor.

摘要： A cache server for providing content includes a processor configured to receive a first datagram from a client system sent to an anycast address, send a response datagram to the client system in response to the first datagram, receive a request datagram from the client system sent to the anycast address, and send a batch of content datagrams to the client system. The first datagram includes a universal resource locator corresponding to the content. The response datagram includes a content identifier for the content. The request datagram includes the content identifier, an offset, and a bandwidth indicator. The batch of content datagrams includes a portion of the content starting at the offset.

摘要： A network is configured to utilize available bandwidth to conduct bulk data transfers without substantially affecting the successful transmission of time-sensitive traffic in the network. In order to avoid this interference, the packets carrying data for bulk data transfers are associated with a low priority class such that the routers of the network will preferentially drop these packets over packets associated with the normal traffic of the network. As such, when the normal traffic peaks or there are link failures or equipment failures, the normal traffic is preferentially transmitted over the bulk-transfer traffic and thus the bulk-transfer traffic dynamically adapts to changes in the available bandwidth of the network. Further, to reduce the impact of dropped packets for the bulk-transfer traffic, the packets of the bulk-transfer traffic are encoded at or near the source component using a loss-resistant transport protocol so that the dropped packets can be reproduced at a downstream link.
摘要翻译：网络被配置为利用可用带宽进行批量数据传输，而不会基本上影响网络中对时间敏感业务的成功传输。为了避免这种干扰，承载大量数据传输数据的分组与低优先级类相关联，使得网络的路由器将优先通过与网络的正常业务相关联的分组来丢弃这些分组。因此，当正常流量峰值或存在链路故障或设备故障时，通常的业务优先通过批量传输业务传输，因此批量传输业务动态地适应网络可用带宽的变化。此外，为了减少丢弃的分组对于批量传输业务的影响，使用丢失传输协议将批量传输业务的分组编码在源组件或其附近，使得丢弃的分组可以在下游再现链接。

摘要： Described is a system and method for receiving a data packet including a destination address and a source address, the data packet corresponding to a port number, assigning an address risk value for the data packet based on the source address and a port risk value for the data packet based on the port number. The data packet is categorized into a community based on the source address, wherein the community is predefined by a user corresponding to the destination address, the community includes a utility value. The address risk value and the port risk value are compared to the utility value to yield a benefit coefficient and the data packet is treated based on the benefit coefficient.

摘要： A system for visualization of performance measurements is disclosed. The system may include an electronic data processor configured to receive a stream of the performance measurements and select a maximum number of leaf nodes of a plurality of nodes for use in an adaptive decision tree. Additionally, the electronic processor may be configured to determine a depth of each branch in the adaptive decision tree needed to differentiate performance among internet protocol addresses in an internet protocol prefix of each node. Each of the plurality of nodes may be annotated with a predicted latency category and the processor may be configured to generate the adaptive decision tree based on the maximum number of leaf nodes selected, the depth of each branch determined, the predicted latency category, and on the stream of performance measurements associated with the network. Moreover, the processor may display the adaptive decision tree.
