    • An approach for establishing secure multicast communication among multiple multicast proxy service nodes is disclosed. The multicast proxy service nodes, which can be distributed throughout an enterprise domain, are organized in a logical tree that mimics the logical tree arrangement of domains in a directory server system. The attributes of the multicast proxy service nodes include the group session key and the private keys of the multicast proxy service nodes that are members of the multicast or broadcast groups. The private keys provide unique identification values for the multicast proxy service nodes, thereby facilitating distribution of such keys. Because keys as well as key version information are housed in the directory, multicast security can be achieved over any number of network domains across the entire enterprise. Key information is stored in, and the logical tree is supported by, a directory service. Replication of the directory accomplishes distribution of keys. Multicast proxy service nodes may obtain current key information from a local copy of the replicated directory.
    • 公开了一种在多个组播代理服务节点之间建立安全组播通信的方法。 可以分布在整个企业域中的多播代理服务节点被组织在逻辑树中,该逻辑树模仿目录服务器系统中的域的逻辑树布置。 组播代理服务节点的属性包括组会话密钥和作为组播或广播组成员的组播代理服务节点的私钥。 专用密钥为组播代理服务节点提供唯一的标识值,从而便于分发这些密钥。 由于密钥以及密钥版本信息都存放在目录中,因此可以通过整个企业的任意数量的网络域实现组播安全。 密钥信息存储在目录服务中,逻辑树由目录服务支持。 目录的复制完成密钥的分发。 组播代理服务节点可以从复制目录的本地副本获取当前密钥信息。

    • An analysis of a business process is received from an analytics application and stored at a decision hub is provided. The analysis may include a problem and a possible solution. The business hub then identifies an entity responsible for the process and the analysis information is sent to the entity. The entity may review the analysis information and determine a decision based on the analysis. For example, the decision approves a change that can be implemented in the process based on the problem and solution received. Information for the decision made is then received and stored at a decision hub. The change in the process may be implemented in an operational application. Result information resulting from the change in the process is then received at the decision hub. The analysis information, decision information, and result information may thus be stored by the decision hub.
    • 从分析应用程序接收业务流程的分析,并提供存储在决策中心。 分析可能包括问题和可能的解决方案。 然后,业务中心识别负责该过程的实体,并将分析信息发送到该实体。 实体可以审查分析信息,并根据分析确定决策。 例如,该决定批准了可以根据所收到的问题和解决方案在过程中实施的更改。 然后收到决定信息并将其存储在决策中心。 该过程的改变可以在操作应用中实现。 然后在决策中心收到由过程变更产生的结果信息。 分析信息,决策信息和结果信息可以由决策中心存储。

    • A method of routing data to a load-balanced server through a network having one or more load-balancing nodes is disclosed, comprising receiving a label value; storing the label value in a load balancing mapping at a load-balancing node in a network, wherein the load balancing mapping associates the label with a packet flow and with interface identifying information; and forwarding subsequent packets of the flow to a selected load-balancing server. The forwarding route is defined by the load-balancing mapping and without hop-by-hop routing decisions. The first server response packet is switched hop-by-hop and the label is stored at each node traversed by the response packets, with a flow identifier and interface identifiers. For other request and response packets, nodes fast-switch the packets based on the label mappings; thus, packet flows are rapidly routed from the client to the same server without time-consuming hop-by-hop routing or repeated load-balancing decisions.
    • 公开了一种通过具有一个或多个负载均衡节点的网络将数据路由到负载平衡的服务器的方法,包括接收标签值; 将所述标签值存储在网络中的负载平衡节点处的负载平衡映射中,其中所述负载平衡映射将所述标签与分组流和接口标识信息相关联; 并将所述流的后续分组转发到所选择的负载平衡服务器。 转发路由由负载平衡映射定义,不需要逐跳路由决定。 第一个服务器响应数据包是逐跳转换的,并且标签被存储在响应数据包遍历的每个节点处,并具有流标识符和接口标识符。 对于其他请求和响应报文,节点根据标签映射快速切换报文; 因此,数据包流从客户端快速路由到同一个服务器,而不需要耗费时间的逐跳路由或重复的负载平衡决策。
