Narrative:
Departing dfw runway 17R on dalls 9 SID, slower traffic (F100) ahead below us, we were instructed to keep him in sight and turn left heading 040 degrees to intercept the dfw 067 degree radial. While established on the 040 degree heading and climbing rapidly to 17000 ft (lightly loaded B757 is a rocket ship) departure control gave us a speed reduction rapidly followed by another speed reduction (the second reduction request in a tone of voice that conveyed some urgency). This occurred as we were passing 16000 ft for 17000 ft. I neglected my standard call '160 for 170 one to go.' because I was dialing in raw data to confirm the dfw 067 degree radial with FMS data. The captain hand flying dialed in the last speed reduction to 250 KTS (because I was busy) and by the time I came back into the climb level slowing situation, we were passing 17500 ft on the way to 17900 ft before the aircraft was slowed and descent to 17000 ft was initiated. I called departure told them out of 17800 ft descending and was told to switch frequencys.

Title: FLC OF AN LGT OVERSHOT ALT DURING CLB.
Narrative: DEPARTING DFW RWY 17R ON DALLS 9 SID, SLOWER TFC (F100) AHEAD BELOW US, WE WERE INSTRUCTED TO KEEP HIM IN SIGHT AND TURN L HDG 040 DEGS TO INTERCEPT THE DFW 067 DEG RADIAL. WHILE ESTABLISHED ON THE 040 DEG HDG AND CLBING RAPIDLY TO 17000 FT (LIGHTLY LOADED B757 IS A ROCKET SHIP) DEP CTL GAVE US A SPD REDUCTION RAPIDLY FOLLOWED BY ANOTHER SPD REDUCTION (THE SECOND REDUCTION REQUEST IN A TONE OF VOICE THAT CONVEYED SOME URGENCY). THIS OCCURRED AS WE WERE PASSING 16000 FT FOR 17000 FT. I NEGLECTED MY STANDARD CALL '160 FOR 170 ONE TO GO.' BECAUSE I WAS DIALING IN RAW DATA TO CONFIRM THE DFW 067 DEG RADIAL WITH FMS DATA. THE CAPT HAND FLYING DIALED IN THE LAST SPD REDUCTION TO 250 KTS (BECAUSE I WAS BUSY) AND BY THE TIME I CAME BACK INTO THE CLB LEVEL SLOWING SIT, WE WERE PASSING 17500 FT ON THE WAY TO 17900 FT BEFORE THE ACFT WAS SLOWED AND DSCNT TO 17000 FT WAS INITIATED. I CALLED DEP TOLD THEM OUT OF 17800 FT DSNDING AND WAS TOLD TO SWITCH FREQS.
