(805) 237-3831, (800) 321-3831 http://www.arbiter.com mailto: [email protected] 1 Option 33: Dual Internal NTP Server 1.1 General Description Option 33, Dual Internal Network Time Protocol (NTP) Server, is used in the Arbiter Systems line of 19-inch, rack mount Satellite-Controlled Clocks. This option comes with a six-foot phone cable and RJ-11 to DB-9F adapter for connecting to the RS-232, or NTP Setup, port. 1.1.1 Option 33 Option 33 allows the clock to act as time server over an Ethernet network using the network time protocol operating in server mode - symmetric operation modes are not supported. Time is distributed over the network interface to computers, controllers and other equipment needing the correct time. Option 33 understands NTP Version 1, Version 2, and Version 3 frames, and optionally supports authentication via DES and MD5 cryptographic checksums. If authentication is not used, the controller can typically be used for hundreds of clients without overloading it. Authentication requires typically 40 ms for checking and generating the cryptograms, which is covered and averaged out by the protocol. Option 33 supports full SNTP and all NTP functions required for reliable server operation. Functions not required for server operation are not implemented. 1.1.2 Hardware Configuration. Option 33 consists of two building blocks; two OEM NTP modules and an interface to the GPS clock.

Over five months, from December 2014 { April 2015, over 2.7 petabytes of traffic on 49 billion connections was observed. This thesis presents traffic characterizations for two large video streaming services, namely NetFlix and Twitch. These two services contribute a significant portion of inbound bytes. NetFlix provides TV series and movies on demand. Twitch offers live streaming of video game play. These services share many characteristics, including asymmetric connections, content delivery mechanisms, and content popularity patterns.
