摘要： Techniques are described for managing periodic communications between devices. For example, a periodic packet process may receive configuration parameters from a routing protocol process. The periodic packet process may manage periodic communication sessions with neighboring devices in accordance with the configuration parameters from the routing protocol process. The periodic packet process may monitor for incoming periodic packets from a specified neighboring device in a specified periodic time interval. The periodic packet process may also send outbound periodic packets at a specified periodic time interval.

摘要： A software module operating within a network device, such as an operating system, manages state information within hierarchically ordered and temporally-linked data structure. The software module sends state change messages to other software modules within the network device, referred to as consumers, in an order that corresponds to the hierarchical order and the temporal linking. The data structure may comprise a plurality of objects to store state information. The operating system may receive event messages that indicate a change to the state information. The objects may be hierarchically linked in accordance with a hierarchy representing relationships of event messages. The objects may be temporally linked in accordance with the order in which the operating system receives event messages. The operating system may traverse the data structure according to the temporal and hierarchical links to select state change messages to send to a consumer.

摘要： A method and system for providing enhanced services for a network. The enhanced services use information about the network which is available to a subnet of communicating processors (such as a set of routers), collectively executing a common distributed technique for disseminating that network information. The router subnet collects network topology information and provides a service using that network topology information, responsive to requests from non-routers coupled to the network (such as a set of host processors). The router subnet also collects information advertised by hosts coupled to the network, and disseminates that host information to substantially all routers, using the common distributed technique for disseminating network topology information. The host information may comprise information about server processes available at the originating host (such as what services are available and to which users those services are available), or may comprise information about client processes operating at the originating host (such as which users are operating those client processes and which services they desire).
