From buying guide as http://www.adobe.com/hk_zh/products/adobe-media-server-family/buying-guide-comparison.html, the AMS Standard Edition is unlimited in RTMP and HTTP.
However, from the white paper as http://www.adobe.com/content/dam/Adobe/en/products/ams/pdfs/ams5-intro-wp.pdf page 5, it did not mention any connection limit?
Will it assume also unlimited?
Yes. RTMP and HTTP are unlimited in Standard. Limits are on SIP and RTMFP
