Measurements of forward multi-jet production rates in deep-inelastic muon-proton scattering are presented. Data were taken with a 490 GeV muon beam incident on a hydrogen target. Jets were defined using the JADE jet finding algorithm. The measured rates are presented as function of W, the hadronic center-of-mass energy and the jet resolution parameter, [ital y][sub [ital cut]], in energies up to W=33 GeV. Good agreement is found in comparisons with predictions of the QCD-inspired Lund Monte Carlo models. Non-perturbative QCD production mechanisms, inside the Lund Model, cannot reproduce the results for energies greater than W[congruent]20 GeV. Sensitivities of the jet rate measurements to the low [ital x] ([ital x][congruent]0.02) gluon content of the nucleon and the evolution of [alpha][sub [ital s]] are studied.
