摘要： A method for protecting firewall load balancers from a denial of service attack is provided. Packets are received by the firewall load balancer. Each packet has a source and a destination. The firewall load balancer is equipped with a connection database that can contain entries about the packets. Upon receipt of a packet, the connection database is queried to determine whether or not there is an entry for the received packet. If an entry is found in the database, the packet is forwarded to its destination. Otherwise, if the packet was received from a firewall, then a new connection entry for the packet is built and is saved to the connection database and the packet is forwarded on to its destination. If the packet does not have an entry (match) in the connection database and the packet was not received from a firewall, then the packet is forwarded to a firewall.

摘要： A method for communicating in a loadbalancing environment is provided that in a particular embodiment includes receiving a request packet from a network access server (NAS) to initiate a communication session. The request packet is then communicated to a tunneling protocol network server (TPNS) and a response packet is received in response to the request packet. The response packet establishes a tunnel that facilitates the communication session and that includes an identification element associated with the TPNS such that a data transfer associated with the communication session is executed between the NAS and the TPNS.
摘要翻译：提供了一种用于在负载平衡环境中通信的方法，其在特定实施例中包括从网络接入服务器（NAS）接收请求分组以发起通信会话。然后将请求分组传送到隧道协议网络服务器（TPNS），并响应于请求分组接收响应分组。响应分组建立一个便于通信会话的隧道，并且包括与TPNS相关联的识别元件，使得在NAS和TPNS之间执行与通信会话相关联的数据传输。

摘要： Maintaining a content category cache includes storing the content category cache at a gateway. The content category cache includes content category mappings, where a content category mapping associates content with one or more categories describing the content. A request requesting content for a user is received. One or more categories associated with the requested content are determined from a content category mapping of the content category cache. The requested content is filtered in accordance with the categories.

摘要： A method for communicating in a wireless application protocol (WAP) network environment is provided that includes receiving a request packet at a WAP gateway and positioning an identifier into the request packet. A content switch then identifies the identifier and correlates the identifier to a source that generated the request packet. An internet protocol (IP) address associated with the source is positioned in the request packet before communicating the request packet to a next destination.

摘要： A computer network includes an inside network and an external network. The inside network may communicate with the external network over a first path through a first inner load balancer, a first set of firewalls, and a second outer load balancer. The inside network may also communicate with the external network over a second path through a second inner load balancer, a second set of firewalls, and a second outer load balancer. In normal operating conditions, traffic is flowing on both the first and second paths. Probes are passed over each path to monitor the operating status of the path. If a failure occurs in the first inner load balancer, its operating status is changed to standby and the second inner load balancer becomes active for the traffic previously handled by the first inner load balancer. The associated first outer load balancer, recognizing that a probe has not been received to indicate an operating state of the first path, changes its state to standby so that the second outer load balancer becomes active for the traffic previously handled by the first outer load balancer.
