Abstract: 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. A fault manager executing on a control blade of multiple server blades of a network routing system actively monitors an active processing engine of multiple processing engines within the network routing system. Responsive to detecting a fault associated with the active processing engine, the active processing engine is dynamically replaced with a non-hot-standby processing engine of the multiple processing engines by (i) determining one or more software contexts that were associated with the active processing engine prior to detection of the fault, and (ii) creating one or more replacement software contexts within the non-hot-standby processing engine corresponding to the one or more software contexts.

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.

Abstract: 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.

Abstract: This is a method for creating Bose-Einstein condensates using low-cost technology at room temperature. The method includes a convenient way for separating the condensate into parts that remain entangled and storing the parts in reliable and stable containers that are suitable for easy transportation. The containers have a convenient method to monitor changes in the state of the condensate.

Abstract: In a network routing system,a control blade provides for redundancy and failover of virtual routers (VRs) instantiated by objects running on processing engines of the several virtual routing engines (VREs). When the control blade detects a failure of one processing engines, it may identify the virtual private networks (VPNs) and/or VRs operating on the failed processing engine. The control blade identifies a set of command lines corresponding with the identified VPNs and VRs, and replays the set of command lines with an identity of a new processing engine to recreate the identified VPNs and VRs on the new processing engine.

Abstract: Disclosed is a routing algorithm that uses a new concept of node metric system for optimizing the throughput of a network, in particular, a shared medium network. The measure of congestion of a path in the network is represented by a path metric which is computed by summing the node metrics of the intermediate nodes on the path. Factors used in computing node metrics include the following: 1. future traffic load from neighboring nodes to the node; and 2. future traffic load from the node to the neighboring nodes.
