Cisco Cisco ACNS Software Version 5.5

For additional information on the ACNS software, IOS software, and the network module hardware, see 
the following documentation:

Network Time Protocol. Protocol built on top of TCP that ensures accurate 
local timekeeping with reference to radio and atomic clocks located on the 
Internet. This protocol is capable of synchronizing distributed clocks within 
milliseconds over long time periods.

Alternate term for service module with installed application software.

Industry-standard protocol for capturing log information for devices on a 
network.

Transmission Control Protocol. Connection-oriented transport-layer 
protocol that provides reliable full-duplex data transmission. TCP is part of 
the TCP/IP protocol stack.

Trivial File Transfer Protocol. Simplified version of FTP that allows files to 
be transferred from one computer to another over a network, usually without 
the use of client authentication (for example, username and password).

User Datagram Protocol. Connectionless transport-layer protocol in the 
TCP/IP protocol stack that exchanges datagrams without acknowledgments 
or guaranteed delivery, requiring that error processing and retransmission be 
handled by other protocols.

Wide Area Application Engine (hardware plus software) that accelerates 
content delivery, while ensuring the maximum scalability and availability of 
the content.
