摘要： A security gateway receives messages transmitted between a server and a client device on a network and parses the messages into a plurality of data objects, such as strings and name-value pairs. The data objects may represent user personal identification information, such as user name, social security number, credit card number, patient code, driver's license number, and other personal identification information. The security gateway uses rules to recognize data objects and validate the data objects to determine whether the recognized data objects are appropriately included within the context. The security gateway may also perform an action on the data objects. Data objects that are not appropriately included in the context may be transformed, suppressed or disallowed.

摘要： The cloud bridge may comprise a tunnel between a datacenter network via a WAN to a cloud network. The cloud bridge makes cloud-hosted applications appear as though they are running on one contiguous enterprise network. With a cloud bridge in place, administrators, tools and the applications believe that the application resides on the enterprise network.

摘要： While each node in a cluster of nodes sources connections with the same IP if each node allocates a port on this IP independently, there may be port clashes. Also, the return traffic is not guaranteed to hit the originating node. These issues are addressed by allocating a port in such a way that the response traffic hashes back to the originating node. A good hash is chosen such that the ports are equally divided among the nodes. When a node leaves, the other nodes take over the port range used by this node. When a node joins, the node takes back its share of ports.
摘要翻译：虽然节点集群中的每个节点都会以相同的IP源连接，如果每个节点分别在此IP上分配一个端口，则可能会有端口冲突。此外，返回流量不能保证打到始发节点。这些问题通过分配端口来解决，使得响应流量返回到始发节点。选择好的散列，使得端口在节点之间被等分。当节点离开时，其他节点接管该节点使用的端口范围。当节点加入时，节点将收回其端口份额。

摘要： Described herein is a method and system for distributing whole and fragmented requests and responses across a multi-core system. Each core executes a packet engine that further processes data packets and data packet fragments allocated to that core. A flow distributor executing within the multi-core system forwards client requests to a packet engine on a core that is selected based on a value generated when a hash is applied to a tuple comprising a client IP address, a client port, a server IP address and a server port identified in the request. The packet engine maintains each element of the tuple and forwards the request to the selected core. The packet engine can also process data packet fragments by assembling the fragments prior to transmitting them to the selected core, or by transmitting the data packet fragments to the selected core.

摘要： In the present solution, when a cluster node sends an Address Resolution Protocol (ARP) request for an external internet protocol (IP), the node sends a message to all the other nodes, which are part of the Cluster Link Aggregation (CLAG) to expect an ARP reply for the IP. When a node in the cluster receives the ARP reply, the node informs the other nodes which are part of the same CLAG to update the Machine Access Control (MAC) address. Also when an ARP entry is learned/updated over a CLAG link as part of an ARP request/Gratuitous ARP, the node learning/updating the ARP entry will inform other nodes which are part of the same CLAG about the learned/updated ARP entry. Nodes in a cluster may communicate between with each other over a dedicated backplane, which may be a separate physical medium.

摘要： The present invention is directed towards forwarding network packets in a cluster network. A predetermined identifier may be inserted into a Media Access Control (MAC) ID field of an Ethernet header of a packet to distinguish various types of traffic. Newly received packets may be identified due to the absence of the identifier. The identifier may be added to the source MAC ID field of the Ethernet header of the packet, and the packet may be distributed to cluster nodes for processing via an inter-node communication bus. Thus, received packets with the identifier in the source MAC ID field may be identified as steered for processing by an internal node of the cluster. After processing the packet, the internal node may transmit the processed packets via the inter-node bus with a destination MAC ID including the identifier.
摘要翻译：本发明涉及在群集网络中转发网络分组。可以将预定标识符插入到分组的以太网报头的媒体访问控制（MAC）ID字段中，以区分各种类型的业务。由于不存在标识符，可能识别出新接收的分组。标识符可以被添加到分组的以太网报头的源MAC ID字段中，并且分组可以被分发到群集节点以经由节点间通信总线进行处理。因此，在源MAC ID字段中具有标识符的接收到的分组可以被识别为被集群的内部节点处理。在处理分组之后，内部节点可以经由节点间总线传送经处理的分组，其中包括标识符的目的地MAC ID。

摘要： The present application is directed towards systems and methods for distributing traffic across nodes of a cluster of intermediary devices through distributed flow distribution (DFD). Upon receipt of network traffic, a cluster node, such as an intermediary computing device or appliance, may internally steer a portion of the traffic via an inter-node communications backplane to one or more other nodes in the cluster so that the load is equally handled by all of the nodes in the cluster. A cluster node may determine whether to process the traffic steered via the backplane by computing a hash of packet parameters of the network traffic. Hash keys may be selected such that uniformity is assured, and the key used in hash computation may be synchronized across all of the nodes so that only one node determines that it should process the particular packets or traffic flow.

摘要： The present invention is directed towards systems and methods for determining failure in and controlling access to a shared resource in a multi-core system. In some embodiments of a multi-core system, individual cores may share the same resource. Additionally, the resource may occasionally fail or need to be reset, and the period during which the resource is being reset may be non-instantaneous. In an embodiment without coordination between the cores, one core experiencing a failure may reset the resource. During the period in which the resource is resetting, another core may interpret the reset as a failure and reset the resource. As more cores interpret the resets as failures, they will trigger resets, quickly resulting in the resource being constantly reset and unavailable. Thus, in some embodiments, a coordination system may be utilized to determine failure of a shared resource and control resets and access to the shared resource.
摘要翻译：本发明涉及用于确定多核系统中的共享资源的故障和控制访问的系统和方法。在多核系统的一些实施例中，各个核可以共享相同的资源。此外，资源可能偶尔会失败或需要重置，资源被重置的时间段可能是非瞬时的。在不具有核心之间的协调的实施例中，经历故障的一个核心可以重置资源。在资源重置期间，另一个核心可能将重置解释为故障并重置资源。随着更多的核心将复位解释为故障，它们将触发复位，迅速导致资源不断复位并且不可用。因此，在一些实施例中，可以利用协调系统来确定共享资源的失败并控制复位和访问共享资源。
