The cost of N+0 sharing is a reduced per medium (e.g., service group) capacity during a failure. That is, some service groups may receive less bandwidth from the active element that is used in the sharing scheme to compensate for the failure. However, this may be preferable to service...
This document describes how to provide redundancy in a multihomed Border Gateway Protocol (BGP) network where you have connections to two separate Internet service providers (ISPs). In the event of a failure of connectivity toward one ISP, the traffic is rerouted dynamically through the other IS...
Redundance is a less common term for excess or superfluity, while redundancy refers to unnecessary repetition or backup systems in technology and employment.
A few seconds after Alice went silent, somebody realized they accidentally pulled the power cord for the Hello network switch. Alice didn't die; Sam just lost touch with her because the Hello network had a problem. Someone quickly plugs the switch back in, hoping nothing bad happened. But i...
A network includes a plurality of nodes and a plurality of links communicatively coupling each of the nodes to at least one respective adjacent node via a first communication channel and to another respective adjacent node via a second communication channel. The nodes and links have a braided ring...
The benefits of redundancy in a network are critical for industrial automation, transforming user experiences and impacting the company’s bottom line. Specific benefits include: Uptime: Redundant networks supports the 24/7 reliability and availability of networks. Security: Security must be redundant to...
In a scenario where CEs are asymmetrically connected to PEs, two CEs connected through a packet switched network (PSN) are connected to three PEs in different ways. One CE is single-homed to a PE, and the other CE is dual-homed to two PEs. This scen...
A system and methods are shown for selecting a packet data serving node (PDSN) for a mobile node in a mobile Internet Protocol network. One method includes responsively to receiving on a first foreign agent control node (FACN) from a radio node a registration request message and determining ...
During testing of network redundancy in a fully meshed enterprise campus, a problem has been reported. Both distribution multilayer switches are fully configured for redundancy; s operate normally when the primary multilayer distrib...
Node deployment is a fundamental issue to be solved in wireless sensor networks. In spite of their random deployment, nodes have to organise themselves to avoid redundancy and transceiver tasks. The network has to guarantee complete coverage and connectivity as long as possible. In this paper, we...
