摘要： A method and system for enhancing a load balancing network's ability to load balance sessions is presented. A session identifier is placed within the TCP packet to enable a new mechanism of load distribution and connection grouping within a load balancing system. Specifically, TCP is invoked by a user application to obtain a unique session identifier value. On receiving such a packet, the destination load balancing system hashes over at least the session identifier value, and the node corresponding to the results of the hash algorithm acquires the packet. This method of hashing ensures that the same node acquires all subsequently received TCP packets possessing the same session identifier regardless of the source IP address or source port information. The node then places an identical session identifier value in the form of a response session identifier in its TCP response packet. When the TCP packet with response session identifier is received at a load balancing system, the node whose session identifier matches the response session identifier acquires it.

摘要： A framework and method are disclosed for supporting changed addresses by mobile network nodes. Such support is provided through enhancements to the mobile network nodes and utilizes DNS servers, Dynamic Host Configuration Protocol (DHCP), and virtual private network (VPN) servers—or their functional equivalents—to dynamically assign a current network address to a mobile node, provide the current network address to an authoritative name server, and thereafter have correspondent nodes update their addresses for the mobile node based upon an address provided by the authoritative name server. A mobile node registers all of its name-to-address mappings with its authoritative DNS server using a time to live of zero. Furthermore, when a mobile node moves outside its home security domain, the mobile node initiates a virtual private network connection to a virtual private server for a security domain.

摘要： A method and system for multicast network transmissions dynamically sets response time parameters for handling negative acknowledgments (NAKs). When the sender receives a NAK for a lost packet, it returns an NAK confirmation (NCF), waits for a back-off time before sending requested repair data, and then waits for a “linger time” during which the sender does not respond to other NAKs for the same lost packet. The back-off time and the linger time are dynamically set according to the position of the requested sequence number in the sender's transmit window such that the back-off time is shorter when the requested data is closer to being flushed out of the transmit window. After receiving the NCF, the receiver waits for a timeout period and resends the NAK if no repair data is received. The timeout period for data receipt is dynamically set according to a statistical average time for receiving repair data from the sender and the estimated sender's transmit window size.

摘要： A dynamic risk management system for operating systems that provides monitoring, detection, assessment, and follow-up action to reduce the risk whenever it rises. The system enables an operating system to protect itself automatically in dynamic environments. The risk management system monitors a diverse set of attributes of the system which determines the security state of the system and is indicative of the risk the system is under. Based on a specification of risk levels for the various attributes and for their combinations, the risk management system determines whether one or more actions are required to alleviate the overall risk to the system.

摘要： A method and system for selectively excluding a program from a security policy is provided. The security system receives from a user an indication of a program with a problem that is to be excluded from the security policy. When the program executes and a security enforcement event occurs, the security system does not apply the security policy. If the problem appears to be resolved as a result of excluding the program from the security policy, then the user may assume that the security policy is the cause of the problem.

摘要： Presented is a system and a method for load balancing multiple globally-dispersed servers based on client-centric performance criteria. The infrastructure of the system includes load balancing domain name servers (DNS-LBs) deployed in close physical proximity to the Internet service providers' points of presence. The DNS-LBs are then able to monitor the performance of the servers from a location close to the clients, which allows the DNS-LBs to select a server that will yield the best performance from that location for the client. A second level of the infrastructure utilizes domain name servers (DNS-Bs) that are deployed on the Internet backbones and regional provides. The authoritative domain name servers (DNS-As) for the servers to be load balanced refer all name queries to these DNS-Bs. The DNS-Bs then refer the queries to one of the DNS-LBs based on a mapping of the DNS-ISP address to its physically proximate DNS-LB. The DNS-LB then returns the IP address of the server that will provide the best performance from that location.
