Some embodiments provide a method for detecting a failure of a layer 2 (L2) bump-in-the-wire service at a device. In some embodiments, the device sends heartbeat signals to a second device connected to L2 service nodes in order to detect failure of the L2 service (e.g., a failure of all the service nodes). In some embodiments, the heartbeat signals are unidirectional heartbeat signals (e.g., a unidirectional bidirectional-forwarding-detection (BFD) session) sent from each device to the other. The heartbeat signals, in some embodiments, use a broadcast MAC address in order to reach the current active L2 service node in the case of a failover (i.e., an active service node failing and a standby service node becoming the new active service node). The unidirectional heartbeat signals are also used, in some embodiments, to decrease the time between a failover and data messages being forwarded to the new active service node.

In a networked computing environment, a server is equipped to assure the integrity of the service components of a service, including the direct service providing component and one or more supporting components as requested, and a client is equipped to request on behalf of an application in need of the service the integrity assurance.

In one embodiment, the request for integrity assurance, and the subsequent conditional request or acceptance of the service is performed in real time.

There is provided methods, devices and computer program products for distributing a plurality of virtual IEEE 802.11 wireless networks through a heterogeneous infrastructure. A terminal sends a service provider request to an access point. The service provider request is forwarded to a master server which searches for available service providers. Acknowledgement information relating to available service providers capable of operatively connecting the terminal to the data communications network via the access point is sent by the master server to the access point. The access point forwards this information to the terminal. The access point may thus distribute a plurality of virtual IEEE 802.11 wireless networks, their number only constrained by the number of distinct identifiable service providers and the memory of the master server. A data connection may be established in the absence of a direct service agreement between the service provider of the terminal and the operator of the access point.

A system and method of escalating non-realtime communications entering a Contact Center. The present invention removes communications that may initially be viewed as requiring deferred assistance, such as those near missing their SLA or those determined to require immediate handling based on identifying a particular important customer, from its shared file folders and “escalating” them to be routed as a live communications, for immediate response by a designated agent. An alternative tiered service model for a digital multimedia contact center assigns an entering contact to an initial immediate or deferred service tier based on routing criteria for the contact and may escalate or de-escalate the contact to a different service tier if the routing criteria changes. The service tier is initially determined based on a media type associated with the contact. The digital multimedia contact center contains a set of media servers, each of which passes a contact of a particular media type to a workflow engine (one for each service tier—immediate and deferred), which executes workflows to direct the processing of contacts at service tiers that require agent activity, for the immediate service tier contacts pass through a set of media routers. Agents are allocated to contacts by a dynamic automated contact distributor and the appropriate media router is used to route the contact to an agent. The workflow engines also execute workflows for agents to control the allocation of agents to contacts.

There is provided methods, devices and computer program products for automatically connecting an IEEE 802.11 terminal to a virtual IEEE 802.11 wireless network and thereby establishing a data connection to a remote data communications network. A terminal sends a service provider request to an access point. The service provider request is forwarded to a master server which searches for an association between the terminal and a service provider and a service provider server for available service providers. Acknowledgement information relating to a service provider server associated with available service providers capable of operatively connecting the terminal to the data communications network via the access point is sent by the master server to the access point. The access point establishes a virtual IEEE 802.11 wireless network based on this. A data connection may be established in the absence of a direct service agreement between the service provider of the terminal and the operator of the access point without requiring a reconfiguration of the terminal.
