Tropos Breakthrough Dynamic Policy-Based Multi-Band Mesh Routing Adds Capacity and Reliability for Service Level Assurance.New Patent-Pending Mesh Software First to Provide Parallel Network Operation for Maximum Capacity and Dynamic Fault Tolerance See fault tolerant. (architecture) fault tolerance - 1. The ability of a system or component to continue normal operation despite the presence of hardware or software faults. This often involves some degree of redundancy. 2. SUNNYVALE, Calif. -- Tropos[R] Networks, the market leader for metro-scale wireless mesh network (1) A network that relies on all nodes to propagate signals. Although the wireless signal may start at some base station (access point) attached to a wired network, a wireless mesh network extends the transmission distance by relaying the signal from one computer to another. systems, today announced its new Spectrum and Application Based Routing Engine (SABRE), the first mesh software that enables intelligent integration of parallel network operation across multiple frequency bands and radio types. SABRE provides rule-based traffic segmentation, carrying traffic for different applications on different spectrum and radios while supporting dynamic fault tolerance in the event of link congestion The condition of a network when there is not enough bandwidth to support the current traffic load. congestion - When the offered load of a data communication path exceeds the capacity. or failure. Tropos developed the SABRE software, an optional capability of the patented Predictive Wireless Routing Protocol The Wireless Routing Protocol (WRP) [1] is a proactive unicast routing protocol for mobile ad-hoc networks (MANETs). WRP uses an enhanced version of the distance-vector routing protocol, which uses the Bellman-Ford algorithm to calculate paths. (PWRP PWRP Predictive Wireless Routing Protocol [R]) that is embedded in every Tropos MetroMesh router, to satisfy the requirements of carriers, municipalities and public safety agencies that need to enhance capacity and reserve spectrum and radio interfaces for specific applications or users. SABRE flexibly combines multiple unlicensed and/or licensed frequency bands, radios and radio types, using rule-based traffic segmentation to select the optimal path and spectrum for each packet. With SABRE, parallel networks using different frequency bands and radios can be configured at the client, mesh and/or capacity injection layers. SABRE dynamically routes traffic based on application, service, priority or other configurable rules. Different frequency bands can carry traffic for different applications or users. SABRE automatically detects faulty, congested con·gest·ed adj. Affected with or characterized by congestion. congested ENT adjective Referring to a boggy blood-filled tissue. See Nasal congestion. or otherwise sub-optimal links at each layer in the network and seamlessly routes traffic to the optimal band for dynamic capacity expansion and fault tolerance. With SABRE and the Tropos 5320, a municipality could, for example, carry video surveillance traffic in the 5 GHz band while using the 2.4 GHz band for consumer access. The municipality could program SABRE to switch the video surveillance traffic to the 2.4 GHz band when there is congestion or a failure in the 5 GHz band while disallowing consumer access to shift to the 5 GHz band under similar circumstances. With future Tropos MetroMesh routers supporting licensed band operation and new radio types such as mobile WiMAX See WiMAX and 802.16. , a similar scenario will be enabled for carriers who wish to provide premium service with a licensed band and standard service with an unlicensed band See ISM band. . Again, SABRE could be configured to switch licensed band traffic to the unlicensed band but not vice versa VICE VERSA. On the contrary; on opposite sides. , providing fault tolerance for the premium service traffic while reserving the licensed spectrum for premium users. Also, carriers could program SABRE to use unlicensed spectrum when its use enhances overall system capacity. "SABRE significantly enhances the reliability and capacity of multi-band mesh networks," said Saar Gillai, Vice President of Engineering and Product Management for Tropos Networks. "It further enhances the field-proven, software-driven MetroMesh architecture, which delivers reliability, scalability and high performance for picocell networks using any radio interface." SABRE, part of the MetroMesh OS that ships with each Tropos MetroMesh router, will be available in mid-2007. Customers with valid Tropos support subscriptions can obtain updated software for their existing MetroMesh routers at no additional cost. About Tropos Networks, Inc.
