it uses port 80.
HTTPS The HyperText Transfer Protocol Secure (HTTPS) is a protocol
which protects against eavesdropping when transmitting HTML
pages (web pages) between server and client. HTTPS is schematic-
ally identical to HTTP. SSL / TLS is used for additional data encryp-
tion. The standard port for HTTPS connections is 443.
Hyperchannel With a hyperchannel, multiple subscribers have access to the trans-
mission medium. A subscriber can only transmit their data if no oth-
er subscriber is using the medium. A hyperchannel network is
mainly used for short-range operation with top data rates.
ICMP The Internet Control Message Protocol (ICMP) is used to exchange
information and error messages over IPv4. The version ICMPv6 ex-
ists for IPv6.
IGMP The Internet Group Management Protocol (IGMP) is used in IPv4
networks to organise multicast groups.
IKE The Internet Key Exchange Protocol (IKE) is used for automatic key
management with IPSec connections. The IKE process runs in two
phases. During phase 1, the IKE subscribers authenticate them-
selves to one another and establish a secure channel. In phase 2,
the two IPSec subscribers negotiate the SAs. There are two ver-
sions of the IKE mechanism.
Infrastructure net- In an infrastructure network the individual terminals (clients) form a
work wireless LAN via a central access point. This central access point
may also be an agent in other networks.
IP The Internet Protocol (IP) is a network protocol and it is the basis for
the Internet. It works on the network layer of the OSI model. The
TCP and UDP protocols are based on IP. There are two versions,
Internet Protocol version 4 (IPv4) and Internet Protocol version 6
(IPv6).
IP address IP addresses are used to navigate in an IP network, to unambigu-
ously identify the source and destination. IPv4 addresses consist of
32 bits, IPv6 addresses of 128 bits. So, with IPv4 232, i.e.
4.294.967.296 addresses can be represented, with IPv6 2128 =
340.282.366.920.938.463.463.374.607.431.768.211.456 addresses.
Dotted decimal notation, e. g. 192.168.0.250, is used for IPv4.
Hexadecimal notation, e. g. 2001:db8:85a3::8a2e:370:7344, is used
for IPv6. See also netmask.
