摘要： A method and apparatus for detecting spoofed IP network traffic is presented. A mapping table is created to indicate correlations between IP address prefixes and AS numbers, based on routing information collected from a plurality of data sources. At each interface of a target network, IP address prefixes from a training traffic flow are acquired and further converted into AS numbers based on the mapping table. An EAS (Expected Autonomous System) table is populated by the AS numbers collected for each interface. The EAS table is used to determine if an operation traffic flow is allowed to enter the network.

摘要： A method, an apparatus and a program for detecting spoofed Internet Protocol (IP) traffic directed to a network having a plurality of autonomous systems (AS) is provided. The method comprises receiving an incoming packet through an AS, the incoming packet containing a source IP address and a destination IP address, acquiring a corresponding source and destination IP address prefixes, converting the corresponding source and destination IP address prefixes into a source AS number and a destination AS number, determining if the incoming packet arrived from an unexpected source based upon the corresponding destination IP address prefix and the converted source and destination AS number using an unexpected pair tuple table generated from network routing information and generating an alert indicating that the incoming packet is not allowed to enter the network.

摘要： An inventive system and method for creating source profiles to detect spoofed traffic comprises obtaining a routing path for data to traverse nodes using traffic profiles, each routing path comprising at least a target AS, initializing one or more AS sets with last hop ASes, enhancing the AS sets by connecting the AS sets to routers, for each enhanced AS set, filtering observed traffic flows, and using the filtered flows to associate enhanced AS sets with network monitoring points to create the source profiles. In one aspect, filtering flows comprise TCP session filtering and/or destination bogon filtering. In one aspect, the routers are border gateway protocol routers. In one aspect, the last hop ASes are one hop away from the target AS.

摘要： Aspects of the invention provide a method and system for managing or coordinating data transmission in a Local Area Network (LAN) such that Quality of Service (QoS) concerns are met. A LAN resource manager (LRM) is provided for managing the LAN resources by providing solutions for providing users with several levels of QoS. Once the LRM admits a user at a certain QoS level, the level is assured within the LAN for as long as the user is in the LAN. A user may submit a request to transmit data to the LRM. The LRM may determine if time allocation is possible and allocate the time slots for data transmission. The LRM may send time slot allocation information to an Access Server in a LAN, which may inform the user of the time slot allocation and prepare a queue according to the slot allocation information.
摘要翻译： 本发明的方面提供了一种用于管理或协调局域网（LAN）中的数据传输的方法和系统，使得满足服务质量（QoS）关注。 提供LAN资源管理器（LRM），用于通过为用户提供多个QoS级别的解决方案来管理LAN资源。 一旦LRM以某个QoS级别承认用户，只要用户在LAN中，该级别就可以在LAN内得到保证。 用户可以向LRM提交发送数据的请求。 LRM可以确定时间分配是否可能并且分配用于数据传输的时隙。 LRM可以向LAN中的接入服务器发送时隙分配信息，这可以通知用户时隙分配，并根据时隙分配信息准备一个队列。

摘要： The present invention advantageously provides several systems and methods for solving the trombone routing issues within an IMS/MMD network. These approaches avoid trombone routing, speed up handoff, and increase the efficiency of signaling and overall performance of an IMS/MMD network. These solutions can broadly be divided into the following categories. Piggy-backing SIP registration over MIP (Split at FA); Selective Reverse Tunneling and Tunneling between FA and P-CSCF; the SIP-based mobility protocol; use of CoA during SIP registration and call up in MIPv6; Piggy-backing SIP registration when HA and S-CSCF Co-exist; Using Dynamic Home Agents in MIPv4 FA-CoA; and the Interceptor-Caching Approach.

摘要： Embodiments of the present invention disclose a secure localization infrastructure using transmitters that can transmit messages at multiple distinct power levels throughout a community of reference points. Transmitters send messages at different power levels in a manner that every location in the system corresponds to a unique set of messages. Received messages are reported back to the localization infrastructure, which then determines location by comparing the messages reported.
