Abstract:
Methods, apparatuses and systems directed to enhanced packet load shedding mechanisms implemented in various network devices. In one implementation, the present invention enables a selective load shedding mechanism that intelligently discards packets to allow or facilitate management access during DoS attacks or other high traffic events. In one implementation, the present invention is directed to a selective load shedding mechanism that, while shedding load necessary to allow a network device to operate appropriately, does not attempt to control traffic flows, which allows for other processes to process, classify, diagnose and/or monitor network traffic during high traffic volume periods. In another implementation, the present invention provides a packet load shedding mechanism that reduces the consumption of system resources during periods of high network traffic volume.
Abstract:
A system and method providing capability expansion in a teleconferencing environment. One or more accessories are invoked and arranged in an accessory stack associated with an application. The accessory stack is positioned logically between a teleconferencing application and a conference component in both a local and a remote end point. Each accessory provides at least one additional capability to the system independent of the application and the conference component.
Abstract:
In one embodiment, the invention provides a method comprising loading a set of transport components into a memory; initializing each transport component of the set of transport components to listen on a particular conferencing interface using a listen string to associate with a network interface, each transport component of the set of transport components listening to a different conferencing interface, the listen string encapsulating parameters to one or more calls to listen; receiving an incoming call signal on the network interface having an incoming conferencing interface; processing the incoming call signal to detect the incoming conferencing interface; and launching an application based on the incoming conferencing interface. Other embodiments of the invention are also described.
Abstract:
Methods, apparatuses and systems directed to a network traffic synchronization mechanism facilitating the deployment of network devices in redundant network topologies. In certain embodiments, when a first network device directly receives network traffic, it copies the network traffic and transmits it to at least one partner network device. The partner network device processes the copied network traffic, just as if it had received it directly, but, in one embodiment, discards the traffic before forwarding it on to its destination. In one embodiment, the partner network devices are operative to exchange directly received network traffic. As a result, the present invention provides enhanced reliability and seamless failover. Each unit, for example, is ready at any time to take over for the other unit should a failure occur. As discussed below, the network traffic synchronization mechanism can be applied to a variety of network devices, such as firewalls, gateways, network routers, and bandwidth management devices.
Abstract:
A system and method for dynamically identifying internal hosts in a heterogeneous computing environment with multiple subnetworks is disclosed. A plurality of packets are analyzed. Each such packet includes a source address of an originating host and a destination address of a receiving host. An unknown originating host located at the source address of an outbound packet is classified as an inside host with high confidence. An unknown receiving host located at the destination address of an inbound packet is classified as an inside host. The unknown receiving host is reclassified as an inside host with high confidence upon receiving a further outbound packet having a source address corresponding to the address of the unknown receiving host.

An apparatus for listening on multiple conferencing interfaces having a set of transport components coupled to the network interface, each transport component of the set of transport components having the capability of receiving a signal on a different conferencing interface; a conference component coupled to each component in the set of transport components; a call processing module coupled to the conference component; and, a process manager coupled to the call processing module; the conference component containing a circuit for causing the call processing module to cause process manager to activate a conferencing application upon detecting a call from one transport component of the set of transport components.
Abstract:
A system and method which enables teleconference members to share files during a teleconference. An endpoint including a processor with a memory coupled thereto. The memory stores a teleconferencing application. A file sharing mechanism is associated with the application at run time. The file sharing mechanism generates a window on the local display in which the local member of the teleconference may post advertisements for files thereby making the file sharable. The local endpoint sends the advertisement to a remote endpoint. A corresponding accessory receives the advertisement and posts it in the remote window. A local member can copy remotely posted files by manipulating the corresponding advertisement.
Abstract:
A workflow management system, a client device, and a method describe business workflow management systems and methods optimized for small to medium-sized businesses. The systems and methods can include a recommendation engine to parse through data to provide a finite and optimized to-do list to business owners and employees to optimize business operation and overall productivity recognizing the inherent constraints in small to medium-sized businesses. The recommendations in the to-do list are based on data analysis using a plurality of factors such as context, time, efficiency, etc. The systems and methods are focused on the needs and objectives of business owners in the context of running a more efficient business. The recommendations seek to be relevant, actionable, and contextually-driven to optimize business operations recognizing that small and medium-sized businesses have finite resources during ongoing operations.
Abstract:
Methods, apparatuses and systems directed to the application of network QoS policy to different data types multiplexed over a connection corresponding to a given session between a first host and a second host. In one implementation, the present invention includes a dual gateway architecture where a first gateway terminates the connection with a remote access client, demultiplexes the remote access session data stream into a plurality of separate streams for transmission to a second gateway. The second gateway re-multiplexes the separate data streams into a single remote access session data stream for transmission to a remote access server. The use of separate data streams between the first and second gateways allows for the application of individual policies on the components of the remote access session data flow. For example, a policy scheme can be configured that gives preference to mouse movements, transmitted in a first data stream, over printer traffic, transmitted in a second data stream. The present invention can also be applied to network application protocols, other than remote access protocols, that multiplex more than one “virtual channel” containing different traffic types over a single transport layer connection.
Abstract:
Methods, apparatuses, and systems directed to efficient compression processing in system architectures including a control plane and a data plane. Particular implementations feature integration of compression operations and mode selection with a beltway mechanism that takes advantage of atomic locking mechanisms supported by certain classes of hardware processors to handle the tasks that require atomic access to data structures while also reducing the overhead associated with these atomic locking mechanisms.
