A middlebox includes a network monitor module configured to determine a quality-affective factor in a connection between a client and a server in a network. A processor is configured to compare the quality-affective factor to a threshold to determine whether the connection would benefit from a network processing function. A network control module is configured to configure a router to exclude the middlebox from the connection if the connection would not benefit from the network processing function and if the middlebox is already present in the connection to cease operation of the middlebox on the connection. Router configuration is delayed until the connection is idle.

Dynamic middlebox redirection based on client characteristics

Traffic engineering of cloud services include receiving, by an enterprise network agent of an enterprise network, a policy from an operator of the enterprise network and transmitting, by a processor, the policy to a cloud service provider. Aspects also include monitoring an incoming traffic to the enterprise network from the cloud service provider and collecting data regarding the incoming traffic and transmitting collected data regarding the incoming traffic to the cloud service provider.

Methods and apparatus are provided for wireless network optimization. Wireless network traffic is optimized by receiving redirected traffic based on one or more configuration rules; and applying the redirected traffic to a protocol optimizer that optimizes the wireless network traffic based on one or more optimization rules. A management interface is optionally provided to manage the network optimization appliance. A process monitor is optionally provided to monitor one or more process threads to determine if the process threads have stalled. The process monitor can monitor other components and can be monitored by at least one other component.

Wireless network optimization appliance

Traffic redirection methods include determining a quality-affective factor comprising a quality-affective factor in an existing connection between a client and a server in a network. The quality-affective factor is compared to a threshold to determine whether the connection would benefit from a network processing function. A router is reconfigured to exclude the middlebox from the connection, if the connection would not benefit from the network processing function and if the middlebox is already present in the connection, to cease operation of the middlebox on the connection. The router reconfiguration is delayed until the connection is idle.

Traffic redirection methods include determining a quality-affective factor in a connection between a client and a server in a network; comparing the quality-affective factor to a threshold to determine whether the connection would benefit from a network processing function; reconfiguring the network to redirect the connection to or away from a middlebox that performs the network processing function in accordance with the determination of whether the connection would benefit from the network processing function.

Dynamic middleboxes include a network monitor module configured to determine a quality-affective factor in a connection between a client and a server in a network; a processor configured to compare the quality-affective factor to a threshold to determine whether the connection would benefit from a network processing function; and a network control module configured to reconfigure the network to redirect the connection to a middlebox that performs the network processing function if the connection would benefit and further configured to reconfigure the network to exclude the middlebox from the connection if the connection would not benefit.

A method and structure for a cloud service includes an API (application programming interface) as tangibly embodied in a set of computer-executable instructions and selectively executable on a computer on a network. The API provides a user interface for a cloud environment comprising one or more virtual machines to be selectively instantiated on at least one computer in the network upon a user request. A library is accessible via the API, the library providing definitions of components available to be instantiated in the cloud environment. The API automatically instantiates an image of a virtual network of components, as defined by a user input request and provides at least one cloud portal providing the user an access to exercise the instantiated virtual network image.
