The OSI Presentation Layer
At this layer applications communicate on a format for exchanging data. The Session layer provides character set conversion and formats the data. It performs encryption and decryption, compression and decompression. More ...
Major Protocols in the TCP/IP Suite
This is a chart of the layers of the TCP/IP Suite and the major protocols in each layer. As you move your mouse pointer over each protocol acronym, a brief description of the protocol appears. This is not a comprehensive list. More ...
X.25 and Frame Relay Overview
Frame Relay originated as an extension of integrated services digital network (ISDN). Its designers aimed to enable a packet-switched network to transport over circuit-switched technology. The technology has become a stand-alone and cost-effective means of creating a WAN. More ...
The OSI Session Layer
The Session layer, layer seven of the OSI model, establishes, synchronizes, maintains and terminates sessions between computers on a network. It establishes a connection ID and authenticates security. More ...
Internet Protocol versions IPv4, IPv5 and IPv6
Internet Protocol is the part of the TCP/IP protocol that is responsible for addressing packets. IPv4 uses a 32-bit address IPv6 uses a 128-bit address. This article describes how IPv4 are converted to IPv6 addresses. More ...
Introducing OpenStack
OpenStack is one of the most popular cloud computing management packages. OpenStack provides a common platform for controlling clouds of servers, storage, network, and even application resources. OpenStack is managed through a web-based interface, a command-line interface (CLI), and an application programming interface (API). More ...
NTP Server Systems - The Network Time Protocol
The Network Time Protocol (NTP) is utilized by NTP Server systems to distribute accurate time information to network time clients. The NTP protocol is widely used throughout the Internet to provide synchronization of computers and processes. This article discusses how NTP server systems utilize the Network Time Protocol to provide networks with an accurate reference of time. More ...
