TC (Traffic Control 맞나?) 로 패킷양을 조절하여 속도제한을 걸 수 있다...
작년 수업시간에 했던 예제가 있긴한데, 관련해서 전체 트래픽을 제한하는 방법....

#tc qdisc add dev (장치명) root tbf rate (원하는속도)Mbit latency 50ms burst 1540
ex) tc qdisc add dev eth0 root tbf rate 10Mbit latency 50ms burst 1540
-> 10Mbit/s 로 속도가 제한됨

#tc qdisc delete dev eth0 root
-> 속도제한 풀기
