Computer Networking Protocols and Standards
Understanding IP Routing
The Transmission Control Protocol/Internet Protocol TCP/IP suite of protocols is the
underlying technology for information exchange on the Internet. This essential reference
shows you how to isolate and resolve common network failures and to sustain optimal network operation. More ...
Free eBook: IPv6 Addressing
All the IPv4 addresses are quickly being used up. The conversion to IPv6 is now underway.
In this free eBook, Aaron Balchunas describes IPv6 and how to configure it to work along
side IPv4. Learn which protocols will need to be updated to work with IPv6. Learn how to configure IPv6. More ...
What's the Difference Between a Packet and a Frame?
When speaking of the data in a network, people often call everything a packet.
A more proper generic term would be protocol data unit or PDU. The specific name
for a PDU depends on at what layer the data unit is in the OSI model. More ...
Networking and Internet Standards Organizations
Without standards, the Internet would be chaos. The primary organization that sets
communications standards for the Internet is the Internet Engineering Task Force (IETF). More ...
Unicast, Multicast, Broadcast. What Does It Mean?
Unicast, Multicast, and Broadcast are different network transmission methods. Unicast is a
transmission between a single sender and a single receiver, while Broadcast is a transmission
from a single sender to all clients on the network. More ...
OSI Network Model
The OSI model was developed years ago as a reference for network protocol and application
designers to build their products with an open standard. That would promote a standard
for developing network devices, interfaces, applications and services that would work
together. It is a model rather than a specification since it defines layers and services
for those layers and how each layer works with the layer above and below it. More ...
IPv4 Address Classes
Originally, IP network numbers were defined with rigid boundaries and grouped into address
classes. Even though address classes was created to facilitate efficient use of the IPv4
address space, because of its rigidity it has been abandoned for more flexible classless addressing. More ...
TCP/IP Protocol Suite
A good portion of the knowledge required to be a network technician relates to the TCP/IP
protocol suite. This article describes the most important protocols in the TCP/IP protocol
suite. Many other less frequently used protocols exist. 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 ...
Video - The Upper Layers 5 Through 7 of the OSI Networking Model
In this video by Kevin Wallace you learn about Layers 5 Through 7 of the OSI networking model. More ...
IPv6 Address Types and Scopes
An IPv6 addresses have a size of 128 bits have three types, unicast, multicast, and anycast. Unicast addresses are for a one-to-one communication.
Multicast addresses are for a one-to-many communication. Anycast addresses are for one node to nearest node of multiple nodes communication. More ...
WAN Network Protocols - DSL, SONET, HDLC, DWDM, DLSW+
This article discusses some of the most implemented Wide Area Networking (WAN) protocols
in enterprise networking environments today including HDLC, DSL, SONET, DWDM, and DLSW+.
HDLC is a Cisco proprietary protocol for designed
for sending data across serial links. More ...
Dynamic Host Configuration Protocol (DHCP) Explained
In the early days of TCP/IP each device on a network had stored on its hard disk a
configuration file that an administrator used to manually assign a static IP address.
Today a network administrator is no longer required to maintain an IP and MAC address
configuration file a server. Every device on a network is automatically assigned a
unique IP address by Dynamic Host Configuration Protocol (DHCP). More ...
