摘要： Methods and apparatus for implementing notification by network elements of packet drops. In response to determining a packet is to be dropped, a network element such as a switch or router determines the source of the packet and returns a dropped packet notification message to the source. Upon receipt of notification, networking software or embedded hardware on the source causes the dropped packet to be retransmitted. The notification may also be sent from the network element to the destination computer to inform networking software or embedded logic implemented by the destination computer that the packet was dropped and notification to the source has been sent, thus alleviating the destination from needing to send a Selective ACKnowledge (SACK) message to inform the source the packet was not delivered. (Too narrow)

摘要： Methods, apparatus, and networks configured to manage network congestion using packet recirculation. The networks employ network elements (e.g., Rbridges in Layer 2 networks and switches/routers in Layer 3 networks) that are configured to support multi-path forwarding under which packets addressed to the same destination may be routed via multiple paths to the destination. In response to network congestion conditions, such as lack of availability of a non-congested port via which a shortest path to the destination may be accessed, a packet may be routed backward toward a source node or forwarded toward a destination along a non-shortest path. The network elements may employ loopback buffers for looping packets back toward a source via the same link the packet is received on.
摘要翻译：配置为使用分组再循环来管理网络拥塞的方法，装置和网络。网络采用被配置为支持多径转发的网络元件（例如，第2层网络中的R桥和第3层网络中的交换机/路由器），在该路径转发下，寻址到相同目的地的分组可以经由多条路径被路由到目的地。响应于网络拥塞状况，诸如可能访问到目的地的最短路径的非拥塞端口的可用性不足，分组可以朝向源节点反向路由，或者沿着非最短路径朝向目的地转发路径。网络元件可以采用环回缓冲器，用于经由分组被接收的相同链路将分组循环回源。

摘要： Methods and systems may provide for obtaining a query image of a scene, wherein the query image includes embedded information and represents the scene at a time of capture. The embedded information may include location data and perspective data. Additionally, user input may be received, wherein the user input identifies a different time than the time of capture. A time-shifted image of the scene may be obtained based on the user input and the embedded information in the query image. Crowd sources and/or other public information sources may also be used to obtain the time-shifted image. In one example, the time-shifted image represents the scene at the different time.

摘要： Methods, apparatus, and systems for distributing network loads in a manner that is resilient to system topology changes. Distribution functions and associated operations are implemented on multiple load splitters such that if a load splitter becomes inoperative, another or other load splitters can forward packets corresponding to flows previously handled by the inoperative load splitter without requiring flow state synchronization to be maintained across load splitters. The distribution functions are implemented in a manner that distributes packets for the same flows to the same servers through system topology changes, addressing both situations when servers fail and/or are taken off-line and when such servers or replacement servers are brought back on-line. The techniques are facilitated, in part, via use of redistributed flow lists and/or Bloom filters that are marked to track redistributed flows. A novel Bloom filter recycle scheme is also disclosed.
摘要翻译：用于以与系统拓扑变化有关的方式分配网络负载的方法，装置和系统。分配功能和相关联的操作在多个负载分配器上实现，使得如果负载分配器变得不起作用，则另一个或其它负载分配器可以转发与由不可操作的负载分配器先前处理的流相对应的分组，而不需要在负载分配器之间维持流状态同步。分发功能的实现方式是通过系统拓扑变化将同一流量的数据包分发到相同的服务器，解决服务器故障和/或脱机时的这两种情况，并将这些服务器或替换服务器重新启动后，线。这些技术部分地通过使用被标记为跟踪重新分发的流的重新分发的流列表和/或布鲁姆过滤器来促进。还公开了一种新颖的Bloom过滤器再循环方案。

摘要： Methods and apparatus relating to network routing protocols to support power savings in network elements. A most utilized link path network topology for a computer network is discovered using a routing protocol such as a Spanning Tree, link-state, or distance vector routing protocol. In view of the most utilized link path network topology, links are identified as candidates for power management under which a power state of the link and associated network ports are managed to save power under applicable link conditions, such as low utilization. Link power-state change conditions are detected, and in response a corresponding change to the power state of a link is effected by changing the power-state of the network ports at the ends of the link. Power state changes include putting a link into a reduced power state, taking a link offline, and powering a link back up.

摘要： One embodiment of the present invention provides a system that facilitates securely forgetting a secret. During operation, the system obtains a set of secrets which are encrypted with a secret key Si, wherein the set of secrets includes a secret to be forgotten and other secrets which are to be remembered. Next, the system decrypts the secrets to be remembered using Si, and also removes the secret to be forgotten from the set of secrets. The system then obtains a new secret key Si+1, and encrypts the secrets to be remembered using Si+1. Finally, the system forgets Si.

摘要： A method and system for utilizing and encryption or decryption agent so as to preclude access by the encryption agent or decryption agent, respectively, to the information being encrypted or decrypted. To preclude access by the encryption agent, a blinding function is applied to the information prior to forwarding such information to the encryption agent for encryption. To preclude access to the information by the decryption agent, a blinding function is applied to the encrypted information prior to forwarding the encrypted information to the decryption agent for decryption. Once the information has been returned, the information is unblinded, leaving an encrypted or decrypted message respectively.

摘要： Methods and apparatus for multiplexing many client streams over a single connection. A proxy server establishes multiple TCP connections with respective clients that desire to access a web server connected to the proxy server via a multiplexed TCP connection. TCP packets received from the clients via the TCP connections are separated out based on their TCP connections, a packet payload data is extracted and added to client data streams. Data segments comprising sequential runs of bits from the client data streams and embedded in multiplexed (MUX) TCP packets that are sent over the multiplexed TCP connection. Upon receipt, the web server de-encapsulates the data segments and buffers them in queues allocated for each TCP connection in re-assembled client data streams. This enables the packet flows transported over the multiplexed connection for the TCP connections to be individually controlled. The multiplexed TCP connection may also be used for forwarding packet payload data generated at the web server to the clients via the proxy server and the client's TCP connections.
摘要翻译：用于通过单个连接复用许多客户端流的方法和装置。代理服务器与希望通过复用TCP连接访问连接到代理服务器的web服务器的相应客户端建立多个TCP连接。通过TCP连接从客户端接收的TCP数据包根据其TCP连接分离出来，提取分组有效载荷数据并将其添加到客户端数据流中。数据段包括来自客户端数据流的位的顺序运行，并且嵌入在通过复用的TCP连接发送的多路复用（MUX）TCP分组中。收到后，Web服务器将重新组合的客户端数据流解封装数据段并将其缓存到为每个TCP连接分配的队列中。这使得通过多路复用连接传输的数据包流可以单独控制TCP连接。复用的TCP连接还可以用于经由代理服务器和客户端的TCP连接将在web服务器上生成的分组有效载荷数据转发给客户端。

摘要： Methods, apparatuses, and systems for controlling interconnections between nodes using virtual nodes are described. A physical node—such as a router, bridge, switch, etc. —stores a virtual cost associated with a virtual link that links virtual nodes of the physical node. A first physical port and a second physical port of the physical node are designated as belonging to a first virtual node and a third physical port of the physical node is designated as belonging to the second virtual node. The first physical port is associated with a first network partition and the second physical port is associated with a second network partition. The physical node transmits a routing information packet that includes the virtual cost.
