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： 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： A security gateway receives messages rejected by a message filter based on a set of rules. The security gateway also receives attributes of the rejected messages that triggered the rules. The security gateway maintains frequencies with which the messages with a particular attribute were rejected by the rules. The security gateway finds rejected messages or attributes having a high frequency of occurrence. Since messages or attributes having a high frequency of occurrences are more likely to represent legitimate requests rather than malicious attacks, the security gateway generates exception rules, which would allow messages that have similar attributes to pass through the gateway.
摘要翻译：安全网关基于一组规则接收消息过滤器拒绝的消息。安全网关还接收触发规则的被拒绝消息的属性。安全网关维护具有特定属性的消息被规则拒绝的频率。安全网关发现具有高频率发生的被拒绝的消息或属性。由于具有高频率出现的消息或属性更有可能代表合法请求而不是恶意攻击，因此安全网关将生成异常规则，这将允许具有类似属性的消息通过网关。

摘要： Server state objects are identified by an intermediate server among packets transmitted between an application server and a client device on a network based upon a stateless communication protocol, by monitoring and analyzing the packets transmitted between the application server and the client device. The packets are parsed into a plurality of name-value pairs. The entropy of the name-value pairs having a same name field is computed, and candidate data objects that are likely to be server state objects are selected based upon the computed entropy. Candidate data objects that were transmitted bi-directionally between the application server and the client device are identified as server state objects.

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： A method of a device for filtering messages routing across a network includes extracting, by a filter configured on the device, a plurality of message components from messages received via a network. The plurality of message components is identified as having at least a field name in common, including a first field name. A learning engine configured on the device creates a list of data types for values of the first field name. The list includes one or more data types of a value of the first field name identified for each of the plurality of message components. The learning engine determines a most restrictive data type from the list of data types for the values of the first field name of the plurality of message components.

摘要： The present application is directed towards systems and methods for ensuring equal distribution of packet flows among a plurality of cores in a multi-core system by identifying a rank of a matrix created from a hash key. If the rank of the matrix is equal to or greater than a divisor of a modulo operation applied to the results of the hash function, then the hash key may be used to ensure equal distribution of packet flows.

摘要： An efficient method for parsing HTML pages identifies pages containing a mix of static and dynamic content. The pages are parsed to form abstract syntax trees (ASTs), which are then cached along with the pages. When a later version of a page is retrieved, it is compared against the cached version, and only those portions of the AST that contain different content are reparsed.

摘要： A method and system for generating a web log that includes transaction entries from transaction queues of one or more cores of a multi-core system. A transaction queue is maintained for each core so that either a packet engine or web logging client executing on the core can write transaction entries to the transaction queue. In some embodiments, a timestamp value obtained from a synchronized timestamp variable can be assigned to the transaction entries. When a new transaction entry is added to the transaction queue, the earliest transaction entry is removed from the transaction queue and added to a heap. Periodically the earliest entry in the heap is removed from the heap and written to a web log. When an entry is removed from the heap, the earliest entry in a transaction queue corresponding to the removed entry is removed from the transaction queue and added to the heap.
