NetWAYS/ISDN – Glossary 63
frame check sequence (FCS), and the end-of-frame flag.
HDLC is used in full-duplex mode, and provides for the ac-
knowledgment of several frames at a time (usually eight).
The number of frames transmitted before acknowledgment
is called the window size.
Header
Data packets are generally transmitted beginning with a
header which contains the source and destination addresses
and identifies the protocol used to interpret the packet.
Header information is often repetitive and thus can be com-
pressed over some links, such as ISDN lines, to increase the
speed of data communication and so save time and costs.
HMAC (Keyed-Hash Message Authentication Code)
Message Authentication Code (MAC) generated using a
keyed hash function. Any hash algorithm can be used. HMAC
signatures are used in all IPsec authentication functions.
ICMP (Internet Control Message Protocol)
ICMP is part of the IP (Internet Protocol) suite. It is situated at
Layer 3 (the Network Layer) of the OSI reference model,
alongside IP itself. ICMP uses the IP packet structure in a
similar way to higher-layer protocols, however.
ICMP is a component of every IP implementation, and trans-
ports only error and diagnostic information for IP. A well-
known service based on ICMP is the program “ping”.
IKE (Internet Key Exchange)
A protocol in the IPsec suite used to negotiate secure con-
nection parameters. IKE is described in RFC 2490.
IP (Internet Protocol)
IP is the Network Layer protocol responsible for addressing
and routing in the TCP/IP protocol family. In general terms,
its purpose is to provide data communication between vari-
ous networks.
