A flow processing facility, which uses a set of artificial neurons for pattern recognition, such as a self-organizing map, in order to provide security and protection to a computer or computer system supports unified threat management based at least in part on patterns relevant to a variety of types of threats that relate to computer systems, including computer networks. Flow processing for switching, security, and other network applications, including a facility that processes a data flow to address patterns relevant to a variety of conditions are directed at internal network security, virtualization, and web connection security. A flow processing facility for inspecting payloads of network traffic packets detects security threats and intrusions across accessible layers of the IP-stack by applying content matching and behavioral anomaly detection techniques based on regular expression matching and self-organizing maps. Exposing threats and intrusions within packet payload at or near real-time rates enhances network security from both external and internal sources while ensuring security policy is rigorously applied to data and system resources. Intrusion Detection and Protection (IDP) is provided by a flow processing facility that processes a data flow to address patterns relevant to a variety of types of network and data integrity threats that relate to computer systems, including computer networks.

Simplified laser drivers for closed path digital optical cables and digital optical cables including the simplified laser drivers. The laser driver can include less transistors than conventional laser drivers for optical communication cables. The laser can include a bias source and modulation source. The bias source can have a single constant current bias point for all laser diodes. The modulation current source can have a single temperature coefficient for all laser diodes. The laser driver can exclude, for example, any one of or combination of temperature compensation of the modulation or bias current sources, external programming of the modulation or bias current sources, power control based on output of the laser diode, and/or control based on feedback received from a monitor device or other sensor within the cables.

The disclosed embodiments provide a system that facilitates the processing of network data. During operation, the system causes for display a graphical user interface (GUI) for configuring the generation of time-series event data from network packets captured by one or more remote capture agents. Next, the system causes for display, in the GUI, a first set of user-interface elements containing a set of statistics associated with one or more event streams that comprise the time-series event data. The system then causes for display, in the GUI, one or more graphs comprising one or more values from the set of statistics. Finally, the system causes for display, in the GUI, a value of a statistic from the set of statistics based on a position of a cursor over the one or more graphs.

Visualizations of statistics associated with captured network data

A content server provides content to a first network device during a data synchronization between the two devices. A middleware filter selectively filters content provided by the content server such that selected content is provided to the first network device. The middleware filter is included within a second network device coupled between the content server and the first network device. The second network device acts as a proxy for the first network device to receive the content provided by the content server. The content is provided from the content server according to a subscription service between the content server and the first network device. The first network device is preferably a personal digital assistant (PDA) and the second network device is preferably a personal computer. Alternatively, the content server is coupled to the first network device, without the second network device coupled in between. In the alternative case, the middleware filter is included within the content server, and the content is selectively provided from the middleware filter, on the content server, to the first network device.

The present invention provides an adapter for enabling a host device having an electrical connector compatible with a first protocol that is not connectable with a connector assembly associated with a second protocol to be usable with the second protocol. The adapter includes a printed circuit board having a first end and a second end. The first end includes a first interface formed to removably connect with an electrical connector associated with a first protocol. The second end includes a second interface formed to removably connect with a connector assembly associated with the second protocol. A method of making the adapter includes configuring the first interface on the printed circuit board and integrating the second interface with the printed circuit board. One embodiment includes an adapter for enabling a host device with SFP electrical connectors to be usable with an SAS/SATA protocol.

The present invention provides for managing resources of chassis that include configurable network diagnostic modules. A computer system receives a request to allocate a chassis resource to a requesting entity. The computer system sends an allocation request message to a chassis that includes the chassis resource. The chassis receives an allocation request message from the requesting computer system. The chassis determines if the requested chassis resource is currently being utilized. The chassis refers to allocation rules to determine if the requested chassis resource can be allocated to satisfy the resource allocation request. The chassis allocates one or more resources according to the allocation rules and returns an allocation response to the requesting computer system. The computer system receives the allocation response and presents the allocation response at the requesting computer system.

A programmable data filtering/searching system for use with a data network. The primary programmable hardware-based filtering and searching portions of the system are integrated onto the same printed circuit board as the data storage device to facilitate efficient filtering and searching of data from a data stream coming from a memory storage device after being captured. In addition, the actual hardware and software used to perform the filtering and searching routines is programmable such that various filter and search criteria can be entered and utilized. The data filtering/searching system also uses metadata in addition to the captured data to minimize the time required to perform certain processes on the data from the data stream.

The present invention provides for discovering diagnostic port functionality in a distributed system. A computer system requests network addresses for one or more chassis. A chassis receives the request for a network address and returns a corresponding network address at least for the chassis. The computer system receives one or more network addresses corresponding to the one or more chassis. The computer system requests resource data from each of the one or more corresponding network addresses. The chassis receives the request for resource data and returns resource data representing at least the current configuration of the chassis to the requesting computer system. The computer system receives resource data representing the configuration of the one or more chassis. The computer system presents the received resource data at the requesting computer system.

Systems and methods for altering a latency of network messages. A latency control system is configured to alter the latency of one or more network messages transmitted in a network. The latency of the network messages may simulate a latency associated with a network connection. A message queue is controlled by the latency control system to implement the latency, which can be increased or decreased. The latency may be increased and/or decreased dynamically.
