    Abstract: An improved method is provided for reducing packet loss using cross layer information. An exemplary method includes: monitoring a transmission state of a data source, where the transmission state is defined in accordance with TCP; marking data packets with a drop preference at an Internet Protocol (IP) layer of the data packets based on the transmission state; and transmitting the marked data packets from the data source.

    Abstract: A session management system is provided for resumption of a previously interrupted session between an application client and an application server. The session management system includes: an application client and a session control agent residing on a mobile network device; and a session manager residing on a router of a home network associated with the mobile network device, such that messages to and from the mobile network device pass through the router. The session manager is able to intercept application information being exchanged between the application client and the application server and store a session state based upon the intercepted application information. The session control agent can subsequently interface with the session manager to restore the session state between the application client and the application server.

    Abstract: The present invention involves a method for multicast file distribution and synchronization in data networks. Specifically, the present invention includes a mechanism for efficient and reliable distribution of a data file from a single source to a large number of receivers using multicast distribution in wide area networks. The multicast file distribution is done by designating a receiver as an active receiver. The active receiver is selected using a novel token granting procedure. Once selected, the active receiver is responsible for generating retransmission requests as well as providing flow control feedback to the server during data transfer. All receivers on the network are offered a chance to become an active receiver in a controlled manner, and only one receiver can be an active receiver at any given time. This process continues until there are no receivers in the group with missing data segments. The second part of the protocol provides synchronization of the file version to ensure that all receivers have the last distributed version of the data file. In addition, the protocol allows newly joined receivers to request the file from the server. The protocol is suitable for applications where a server periodically distributes a new version of the data file to receivers in the network. In addition, the protocol can be deployed with or without the support of Internet Protocol (IP) multicast technology, and is not tied to any particular network topology or transmission medium./C

    Abstract translation: 本发明涉及数据网络中多播文件分发和同步的方法。 具体地,本发明包括一种用于在广域网中使用多播分发从单个源向大量接收机高效可靠地分发数据文件的机制。 通过将接收机指定为活动接收机来完成多播文件分发。 使用新的令牌授予程序选择活动的接收器。 一旦被选择,活动的接收机负责产生重传请求,并且在数据传输期间向服务器提供流量控制反馈。 网络上的所有接收机都有机会以受控的方式成为一个有效的接收机,在任何给定的时间只有一个接收机可以是一个有效的接收机。 此过程继续,直到组中缺少数据段的接收器。 该协议的第二部分提供文件版本的同步,以确保所有接收器具有数据文件的最后分发版本。 此外,协议允许新加入的接收者从服务器请求文件。 该协议适用于服务器周期性地将新版本的数据文件分发到网络中的接收者的应用。 此外,该协议可以部署有或没有互联网协议(IP)组播技术的支持,并且不绑定到任何特定的网络拓扑或传输介质。
