Cover Story 2 Merits and demerits of best-effort services - Deep-rooted "negative" impressions, feelings of unfairness, and its ambiguity must be removed It is now questioned again how the quality and assurance of best-effort communications services should be.  The concept of best effort is indispensable to spread broadband lines that are required for voice calls and video delivery.  If feelings of unfairness and ambiguity were left unresolved, however, the concept could become shackles crippling the deployment of such services as video delivery in the future.
