    • 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.
    • 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。

    • 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.
    • 与网络路由协议相关的方法和设备,以支持网元的节电。 使用诸如生成树,链路状态或距离矢量路由协议的路由协议来发现用于计算机网络的最有效的链路路径网络拓扑。 鉴于最广泛使用的链路路径网络拓扑,链路被识别为用于电力管理的候选,其中管理链路和相关网络端口的电力状态以在适用的链路条件(例如低利用率)下节省功率。 检测到链路功率状态改变状况,并且作为响应,通过改变链路端的网络端口的功率状态来实现对链路的功率状态的相应改变。 电源状态改变包括将链路置于降低功率状态,使链路脱机,并为链路供电。

    • 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.

    • 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.
    • 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。
