摘要： A load balancer dynamically load balances packets for network connections between clients and servers. When receiving a packet from a client that requests a new connection, the load balancer checks the current load of all the servers and selects the server most suitable to handle the new connection. The load balancer then forwards that packet to the selected server. If the server accepts the request for the new connection, then the server responds with an acknowledgement packet. The acknowledgement packet also includes the server's blade identification that the client uses for all subsequent packets on the accepted connection. When the load balancer receives a packet containing the blade identification, the load balancer forwards the packet to the server corresponding to the blade identification. Backup load balancers can therefore continue packet forwarding services in a smooth and efficient manner.

摘要： A method and node for supporting PDSN load optimization in a CDMA2000 network. The Packet Core Network Manager calculates network statistics and uses the resulting numbers to set the PPP inactivity timer depending on the load on the PDSN. In a preferred embodiment, the calculation gives the mean value of the durations of the PPP sessions (KPI1), and the corresponding standard deviation (KPI2). The PPP inactivity timer is then set to M*(KPI1+KPI2) during low load, to M*KPI1 during normal load, and to M*(KPI1−KPI2) during heavy load, where 0

摘要： A system and method in a General Packet Radio Service (GPRS) network for automatically configuring Network Service Entity Identifiers (NSEIs) in a Base Station System (BSS) and a Serving GPRS Support Node (SGSN) when the BSS is reconfigured. The Gb interface between the BSS and the SGSN is modified to operate using the Internet Protocol (IP), and the BSS and the SGSN are configured to run on IP. Whenever a new Network Service Entity (NSE) is added to an existing BSS, or a new BSS is added to the network, the BSS automatically sends a modified Network Service (NS′)-Reset message to the SGSN requesting an NSEI. The SGSN dynamically allocates a free NSEI from a pool of NSEIs and sends it to the BSS. When an NSE is removed from the BSS, the BSS automatically sends a modified NS′-Reset message to the SGSN to free an NSEI. The SGSN de-allocates the NSEI, and returns the NSEI to the pool of free NSEIs. All related entries for Base Station System GPRS Protocol (BSSGP) Virtual Circuit Identifiers (BVCIs) under the de-allocated NSEI are also removed by the SGSN.

摘要： A system and method in an IP-based network for defining a specific router for a host to utilize as a default router. The host is configured with a plurality of preferred correlation values, each of which has a different corresponding preference level. Routers send Router Advertisement (RA) messages to the host and include at least one router correlation value and at least one corresponding priority value. The host compares the received router correlation values with its preferred correlation values and identifies the router that sent the router correlation value that matched the preferred correlation value having the highest corresponding preference level. The identified router is selected as the host's default router. If more than one router matches the preferred correlation value having the highest corresponding preference level, the router that sent the highest priority value is selected.

摘要： Providing resiliency for mobile terminal data sessions, wherein the data sessions rely on Internet Protocol Version 4 and wherein at least one Home Agent node maintains a mobility bindings database for all registered mobile terminals while they are away from a home network. A first aspect of the invention provides physical Home Agent redundancy, perceived by each mobile node as Home Agent IP address redundancy, and a second aspect provides session resiliency. While the second aspect of the invention provides for session resiliency, it uses a mechanism of the former for master failure detection and Home Agent IP address take-over by a backup Home Agent.

摘要： In an IP-based Code Division Multiple Access (CDMA) 2000 packet-data cellular telecommunications network, a method and system for handing over a dormant Mobile Node (MN) to a target packet zone. According to the invention, first the dormant MN sends an origination request message to the target Base Station Controller and Packet Control Function (BSC/PCF), which further sends a registration request comprising an indication that the MN is dormant to a Packet Data Service Node (PDSN). The PDSN replies to the BSC/PCF with a registration reply message for requesting the establishment of a traffic channel for the MN, and for indicating that it has data packets ready to be sent to the MN, such as for example Link Control Protocol (LCP) data packets for use in the negotiation of a new Point-to-Point Protocol (PPP) connection. The registration reply message comprises an indication such as for example a Data ready to Sent (DRS) parameter set to 1. The BSC/PCF establishes the traffic channel and forwards the data packets to the MN. Following the receipt of the registration reply in the BSC/PCF, the paging of the MN is avoided.

摘要： A system, method and node for supporting PDSN load balancing in a CDMA2000 network. A mobile node (MN) sends an origination message to a BSC/PCF that sends a registration request indicating that it supports load balancing according to the invention to the manager part of a PDSN that selects an agent to take care of the connection and redirects the request to it. The agent then validates the request and sends a reply to the BSC/PCF indicating that the initial request has been redirected. The reply also comprises the IP address of the agent. The BSC/PCF then sets up an A10 connection with the agent, and the MN and the agent negotiate a PPP session. There is further a method of setting up a connection between two entities, via a third entity.

摘要： A method and apparatus adapting a Virtual Router Redundancy Protocol (VRRP) between a set of physical SEGs that realize a V-SEG function towards a remote IPsec/IKE peer. In tandem with the VRRP, a new protocol, referred to herein as the IPsec/IKE SA Transfer Protocol (SATP), is introduced to exchange IKE and IPsec SA information between VRRP capable SEGs. SATP synchronizes all participating SEGs with respect to dynamic IPsec state information in near real time. Thus, in the event of a master VRRP SEG failure, one of the hot-standby SEGs takes over the V-SEG function. This allows the V-SEG function to remain functional despite the possible failure of one or more participating SEGs.
摘要翻译：一种在对远程IPsec / IKE对等体实现V-SEG功能的一组物理SEG之间适配虚拟路由器冗余协议（VRRP）的方法和装置。与VRRP一起，引入了一种称为IPsec / IKE SA传输协议（SATP）的新协议，用于在支持VRRP的SEG之间交换IKE和IPsec SA信息。 SATP可以实时地将所有参与的SEG与动态IPsec状态信息进行同步。因此，在主VRRP SEG故障的情况下，其中一个热备用SEG接管V-SEG功能。这允许V-SEG功能保持功能，尽管一个或多个参与的SEG可能发生故障。
