Abstract

See full text

Computer system, method and program for making routing decisions. A best routing path according to an OSPF, IGRP, EIGRP, BGP or other routing function that can provide multiple routing paths is determined. A first multiplicity of routers in the best routing path is determined. If each of the first multiplicity of routers had a degree of availability and/or quality of signal during a predetermined prior interval that met predetermined respective thresholds, the message packet is forwarded to a next hop in the best routing path. If not, a second multiplicity of routers in a second best routing path determined according to said OSPF, IGRP, EIGRP, BGP or the other routing function is identified. If each of the second multiplicity of routers had a degree of availability and/or quality of signal during a predetermined prior interval that met respective thresholds, the message packet is forwarded to a next hop in the second best routing path.
