摘要： A system for facilitating persistent communications between entities in a network. In a specific embodiment, the system is adapted to facilitate fast reauthentication of a client performed by a server, such as an Authentication, Authorization, and Accounting (AAA) server, that is coupled to the client via a load balancer. The system includes a first message to be exchanged between the server and the client, wherein the first message includes a field identifying the server and/or the client. A matching module communicates with or is otherwise incorporated within the load balancer. The matching module includes one or more routines for employing the field to selectively route the first message to the client and/or server. In a more specific embodiment, the server a fast reauthentication module adapted to append the field in the message. The field includes sub-realm information identifying the server.

摘要： A method for loadbalancing in a network environment is provided that includes receiving a request from an end user for a communication session at a central node. The method further includes identifying a selected one of a plurality of network nodes to facilitate the communication session for the end user based on feedback information provided by the selected network node. The feedback information is communicated from the selected network node and processed before making a decision to establish the communication session between the selected network node and the end user.

摘要： Techniques and systems for server farm load balancing and resource allocation are disclosed. In one embodiment, a method of load balancing can include: arranging servers into service groups; receiving an access request with information related to a differentiation between the service groups; selecting one of the service groups based on a mapping comparison to the information; and selecting one of the servers within the selected service group based on a hardware utilization comparison. The servers can include GPRS (General Packet Radio Service) Gateway Support Node (GGSN) or Remote Authentication Dial In User Service (RADIUS) servers, for example. The information can include an Access Point Name (APN) or Calling Station ID, for example.

摘要： In one embodiment, a method for providing an ACK packet while queuing data is provided. One or more packets in a series of packets may be received from a client at a gateway. The gateway determines that a packet in the series of packets has not been received. The one or more packets are then queued. The queued packets may have included an ACK for one or more previously sent packets. Thus, if the gateway had forwarded the one or more packets that are queued, then the ACK would have been received by the server. However, the one or more packets are queued and thus the ACK included in the packets is not sent with the queued packets. Even though the plurality of packets are queued, an acknowledgement packet is generated and then sent for the previously sent packets. The acknowledgement packet acknowledges to the server that the one or more previously sent packets were received by the client. The server may then continue transmitting packets to the client and knows it does not need to retransmit the one or more previously sent packets.
摘要翻译：在一个实施例中，提供了一种在排队数据期间提供ACK分组的方法。一系列分组中的一个或多个分组可以从网关的客户端接收。网关确定未收到一系列数据包中的数据包。然后将一个或多个数据包排队。排队的分组可以包括用于一个或多个先前发送的分组的ACK。因此，如果网关转发了排队的一个或多个数据包，则该服务器将接收该ACK。然而，一个或多个分组被排队，因此包中的ACK不与排队的分组一起发送。即使多个分组被排队，生成确认分组，然后发送给先前发送的分组。确认分组向服务器确认客户端接收到一个或多个先前发送的分组。然后，服务器可以继续向客户端发送分组，并且知道它不需要重传一个或多个先前发送的分组。

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.
摘要翻译：计算机网络包括内部网络和外部网络。内部网络可以通过第一内部负载平衡器，第一组防火墙和第二外部负载平衡器在第一路径上与外部网络进行通信。内部网络还可以经由第二内部负载平衡器，第二组防火墙和第二外部负载平衡器在第二路径上与外部网络进行通信。在正常操作条件下，流量在第一和第二路径上流动。探针通过每个路径来监视路径的运行状态。如果在第一内部负载平衡器中发生故障，则其运行状态将更改为待机状态，而第二个内部负载平衡器变得对先前由第一个内部负载均衡器处理的流量变为活动状态。相关联的第一外部负载平衡器识别出尚未接收到探测器以指示第一路径的操作状态，将其状态改变为待机状态，使得第二外部负载平衡器变得对先前由第一外部负载平衡器处理的流量起作用。

摘要： A method for monitoring a state associated with a support node is provided that includes receiving one or more communication flows from a first support node, the first support node communicating a message to a second support node that propagates through a loadbalancer. Activity associated with the second support node is then monitored. The method also includes removing one or more communications tunnels associated with the second support node when the second support node does not respond to the message communicated by the first support node.

摘要： An apparatus for charging in a network environment is provided that includes an access gateway encapsulation/decapsulation element operable to establish one or more packet data protocol (PDP) links on behalf of an end user and to perform encapsulation and decapsulation operations for one or more of the links associated with the end user. The access gateway encapsulation/decapsulation element is further operable to interface with a client services packet gateway (CSPG) that is operable to provide enhanced packet processing for the end user for requested information. The apparatus also includes an access gateway policy element operable to interface with the CSPG. The access gateway encapsulation/decapsulation element and the access gateway policy element cooperate to use one or more inter-module headers in order to coordinate the enhanced packet processing for one or more communication flows associated with the end user.
