摘要： A method of timing an attempt to establish a connection path between a first and second node in a communications network is provided. The method initiates the attempt to establish a connection path after a period of time has elapsed wherein the period of time is greater than another period of time which had previously elapsed between two previous attempts, if any, to establish the connection.
摘要翻译：提供了一种定时尝试在通信网络中的第一和第二节点之间建立连接路径的方法。该方法开始尝试在经过一段时间之后建立连接路径，其中该时间段大于先前在两次之前尝试之间经过的另一时间段（如果有的话）以建立连接。

摘要： The present invention is a method and apparatus for selecting a route for a flow from a plurality of network paths connecting a source to a destination. The method comprises: (a) determining cumulative costs for a plurality of candidate paths from the network paths using a cost bias which is dynamically calculated based on at least one of a flow attribute and a path attribute; and (b) selecting an optimal path having a minimum of the cumulative costs. The optimal path corresponds to the selected route.
摘要翻译：本发明是一种用于从连接源到目的地的多个网络路径中选择流的路由的方法和装置。该方法包括：（a）使用基于流属性和路径属性中的至少一个动态计算的成本偏差来确定来自网络路径的多个候选路径的累积成本; 和（b）选择具有最小累积成本的最优路径。最佳路径对应于所选择的路线。

摘要： A forwarder for use within an internetworking system operating over an ATM backbone is provided. The physical internetworking devices within the system are shared to provide the internetworking functions while servicing two or more distinct and isolated user networks. This is accomplished by logically partitioning the devices into distinct sub-elements which provide all or part of the internetworking functions. These sub-elements are uniquely allocated to independent realms which are then assigned to specific user networks.

摘要： A packet transfer apparatus connects two networks of different protocols. The packet transfer apparatus, connected to a first communication network and a second communication network, performs the steps of: storing first destination correspondence information; receiving a packet of the first communication protocol; based on the first destination correspondence information, determining destination information of a packet of the second communication protocol corresponding to destination information of the received packet of the first communication protocol; generating the header of the packet of the second communication protocol, based on the determined destination information of the packet of the second communication protocol; converting the received one or more packets of the first communication protocol into one or more packets of the third communication protocol; and adding the generated header of the packet of the second communication protocol to the packets of the third communication protocol.

摘要： An apparatus and method to provide a portable networking interface for distributed switching systems. Two Application Program Interfaces (APIs) are defined for communication to a Forwarding Database Distribution Library (FDDL). The FDDL sits between network client applications and the switch device driver in order to provide a uniform interface to the switch device driver. Towers may be added to the FDDL to provide additional functionality specific to certain client applications.
