摘要： 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.

摘要： In one aspect the invention provides a method for allocating bandwidth in a network appliance where the network appliance includes a plurality of guaranteed bandwidth buckets used to evaluate when to pass traffic through the network appliance. The method includes providing a shared bandwidth bucket associated with a plurality of the guaranteed bandwidth buckets, allocating bandwidth to the shared bandwidth bucket based on the underutilization of bandwidth in the plurality of guaranteed bandwidth buckets and sharing excess bandwidth developed from the underutilization of the guaranteed bandwidth allocated to the individual guaranteed bandwidth buckets. The step of sharing includes borrowing bandwidth from the shared bandwidth bucket by a respective guaranteed bandwidth bucket to allow traffic to pass immediately through the network appliance.
摘要翻译：在一个方面，本发明提供了一种在网络设备中分配带宽的方法，其中网络设备包括用于评估何时通过网络设备传送流量的多个保证带宽桶。该方法包括提供与多个保证带宽桶相关联的共享带宽桶，基于多个保证带宽桶中的带宽利用不足而分配带宽到共享带宽桶，并且分担从保证带宽的利用不足而产生的超额带宽分配给个人保证带宽桶。共享的步骤包括通过相应的保证带宽桶从共享带宽桶借用带宽，以允许流量立即通过网络设备。

摘要： A system protects database operations performed on a shared resource. The system may chunk memory to form a set of memory chunks which have memory blocks, at least some of the memory blocks including database objects. The system may configure at least one binary search tree using the memory chunks as nodes and buffer a set of pointers corresponding to the memory blocks. The system may further validate the buffered pointers and dereference validated buffered pointers.

摘要： Systems, apparatus, methods, and computer program products for multicast access control are provided to analyze incoming data based on a source zone and a destination zone of the incoming data. Appropriate access control rules are applied to incoming data based on the results of the analysis. Additional implementations of a multicast access control include using a proxy rendezvous point operable to function as a rendezvous point in place of a physical rendezvous point.
