  • Patent number: 9853948
    Abstract: Methods and systems for a flexible, scalable hardware and software platform that allows a managed security service provider to easily provide security services to multiple customers are provided. According to one embodiment, a method is provided for delivering customized network services to subscribers of the service provider. A request is received, at a service management system (SMS) of the service provider, to establish an Internet Protocol (IP) connection between a first and second location of a first subscriber of the managed security service provider. Responsive to the request, the SMS causes a tunnel to be established between a first and second service processing switch of the service provider which are coupled in communication via a public network and associated with the first location and the second location, respectively.

  • Patent number: 8650390
    Abstract: Methods and systems for a flexible, scalable hardware and software platform that allows a managed security service provider to easily provide security services to multiple customers is provided. According to one embodiment, a request to establish an IP connection between two locations of a subscriber is received at a service management system (SMS) of the service provider. A tunnel is established between service processing switches coupled in communication through a public network. First and second packet routing nodes within the service processing switches are associated with the first and second locations, respectively. An encryption configuration decision is bound with a routing configuration of the packet routing nodes, by, when the request is to establish a secure IP connection, configuring, the packet routing nodes to cause all packets transmitted to the other location to be encrypted and to cause all packets received from the other location to be decrypted.

  • Patent number: 8250357
    Abstract: A flexible, scalable hardware and software platform that allows a service provider to easily provide internet services, virtual private network services, firewall services, etc., to a plurality of customers. One aspect provides a method and system for delivering security services. This includes connecting a plurality of processors in a ring configuration within a first processing system, establishing a secure connection between the processors in the ring configuration across an internet protocol (IP) connection to a second processing system to form a tunnel, and providing both router services and host services for a customer using the plurality of processors in the ring configuration and using the second processing system. A secure communications tunnel is formed by routing all packets for the tunnel through an encrypting router at the sending end to obtain encrypted packets, and routing the encrypted packets through a decrypting router at the receiving end of an IP connection.

  • Patent number: 5541911
    Abstract: Network traffic from a central device across a communication link to a remote device is controlled based upon central traffic management resources in the central device. The central traffic management resources are coupled to a communication link and monitor data packets received across the communication link to learn characteristics of the remote network. Based on the learned characteristics, traffic management messages are generated in the central traffic management resources. These messages are forwarded to an interface device on the remote network, where traffic on the communication link is controlled in response to the traffic management messages. Thus, the remote interface is configured automatically by central traffic management resources running in the central device without human intervention at the remote network. The traffic management messages manage traffic across a communication link of two types.
