    Abstract: A network device is described in which a dedicated resource scheduler monitors memory consumption to provide for improved processing of communication sessions. The scheduler maintains a dependency list of communication sessions, and reserves memory for communication sessions as requests for memory are received. The amount of memory reserved is determined based on the amount of memory currently reserved for the communication sessions in the dependency list. The network device may control ongoing communication sessions by way of window manipulation. Communication sessions are processed in a first mode when available memory has not reached a predetermined amount, while communication sessions are processed in a second mode when available memory reaches a predetermined amount.

    Abstract: Methods of screening incoming packets are provided. A first firewall detects a tunnel formation. A second firewall maintains a list of open firewall sessions. Each tunnel has one or more associated firewall sessions. The first firewall detects variable situations, such as when the tunnel is torn down, and notifies the second firewall so that, for example, the second firewall can act to clear an associated firewall session from the firewall session list. Incoming packets that are associated with firewall sessions that have been cleared from the firewall session list may not be passed through the second firewall.

    Abstract: A system establishes a virtual private network (VPN) tunnel to a destination and determines a next hop for the VPN tunnel. The system inserts the next hop, and an address associated with the destination, into an entry of a first table. The system inserts the next hop, and a tunnel identifier corresponding to the established VPN tunnel, into an entry of a second table. The system associates one or more security parameters, used to encrypt traffic sent via the VPN tunnel, with the tunnel identifier.

    Abstract: A network device implements congestion management of sessions of a network protocol. In one implementation, an incoming request component receives session requests for a negotiation session between the network device and a second network device. A capacity pool stores a value relating to capacity of the network device to continue to efficiently process the session requests. New sessions are initiated when the value stored in the capacity pool is less than an estimate of the capacity of the network device at which the network device maximizes processor usage while minimizing session timeouts.

    Abstract: A virtual private network (VPN) tunnel is established that extends from a source spoke to a destination spoke in a hub-and-spoke enterprise network. Prior to establishing the VPN tunnel, packets are sent from the source spoke to the destination spoke through the hub network. In this manner, packets are not dropped while the VPN tunnel is being set up. The VPN tunnel is established by querying a server for the network address of a destination router in the destination spoke, then setting up the VPN tunnel using a secure communication protocol. An extension to the Internet Key Exchange (IKE) protocol is used to obtain the private network address of the destination router during setup of the VPN tunnel. A forwarding table is updated after the VPN tunnel is established to reroute the packets through the new VPN tunnel.
