    摘要： A method of multiplexing multiple terminals in a distributed network includes transporting user traffic and telephony signaling information. Transporting user traffic includes converting the user traffic into ATM cells, passing the ATM cells over a wireless link to a TDM port in an ATM multiplexer wherein the ATM multiplexer includes an ATM circuit emulation service, and converting the ATM cells into user traffic. Transporting telephony signaling information includes extracting the telephony signaling information from a user interface, passing the telephony signaling information to a base station using an ATM virtual circuit, processing and aggregating a number of telephony signaling information into a single channel, and transmitting the single channel to the ATM multiplexer.

    摘要： Methods and systems for facilitating fault tolerance in a non-hot-standby configuration of a network routing system are provided. According to one embodiment, a failover method is provided. One or more processing engines of a network routing system are configured to function as active processing engines, each of which having one or more software contexts. A control blade is configured to monitor the active processing engines. One or more of the processing engines are identified to function as non-hot-standby processing engines, each of which having no pre-created software contexts corresponding to the software contexts of the active processing engines. The control blade monitors the active processing engines. Responsive to detecting a fault associated with an active processing engine the active processing engine is dynamically replaced with a non-hot-standby processing engine by creating one or more replacement software contexts within the non-hot-standby processing engine corresponding to those of the active processing engine.

    摘要： Methods and systems for facilitating fault tolerance in a non-hot-standby configuration of a network routing system are provided. According to one embodiment, a method is provided for replacing an active processing engine with a non-hot-standby processing engine. Multiple processing engines within a network routing system are configured. The processing engines include an active processing engine having one or more software contexts, representative of a set of objects implementing a virtual router, for example, and a non-hot-standby processing engine having no pre-created software contexts corresponding to the one or more software contexts. Responsive to determining a fault associated with the active processing engine, the active processing engine is dynamically replaced with the non-hot-standby processing engine by creating replacement software contexts within the non-hot-standby processing engine corresponding to the one or more software contexts.

    摘要： Passive replication methods and systems to facilitate fault tolerance in a network routing system are provided. In one embodiment, a fault associated with a processing engine (PE) of a network routing system is detected by monitoring the health of the network routing system PEs. Responsive to detecting a fault (e.g., a link failure, a failure of a virtual router (VR) or a failure of the PE): VRs that were operating on the PE prior to detection of the fault are identified; configuration information (e.g., a set of command lines in a configuration file) associated with the identified VRs is identified; and the identified VRs are dynamically recreated on a new PE based on the configuration information. For example, a command line interface engine may replay the command line set with a new slot ID and a PE ID of the new PE to recreate the VRs on the new PE.
