– Network interface controller (NIC).» It can also be called a network interface card.» The NIC is how a device connects to a network.» It works at two layers of the OSI model.

• At Layer 2 (the data link layer), it provides the functional means of network communication by determining which networking protocols will be used (e.g., Ethernet and Point-to-Point Protocol). It also provides the local network node address through its burned in physical MAC address.

• At Layer 1 (the physical layer), it determines how the network data traffic will be converted a bit at a time into an electrical signal that can traverse the network media being used.

» Most modern computers come with at least one built in Ethernet NIC.

» Routers and other network devices may use separate modules that can be inserted into the device to provide the proper NIC for the type of media they are connecting to and the networking protocol that is being used.

– RADIUS (Remote Authentication Dial In User Service).

» A remote access service that is used to authenticate remote users and grant them access to authorized network resources.

» It is a popular AAA (Authentication, Authorization and Accounting) protocol used to help ensure that only authenticated end users are using the network resources they are authorized to use.

• The accounting features are very robust.» Only the requestor’s (the end user’s) password is

encrypted.

– TACACS+ (Terminal Access Controller Access-Control System Plus).

» A remote access service that is used to authenticate remote devices and grant them access to authorized network resources.

» It is a popular AAA protocol used to help ensure that only authenticated remote network devices are using the network resources they are authorized to use.

• The accounting features are not as robust as those of RADIUS.

» All transmissions between devices are encrypted.

RAS (Remote Access Services).

Not a protocol, but a roadmap.

A description of the combination of software and hardware required for a remote access connection. A client requests access from a RAS server, which either grants or rejects access.

Web services.Creating a means of cross communication.

Provides the means for communication between software packages or disparate platforms. It is usually achieved by translating the communication into an XML (Extensible Markup Language) format.

Unified voice services.Creating better voice communication systems.

A description of the combination of software and hardware required to integrate voice communication channels into a network.

What was covered.Networking services and applications II.

The NIC operates at both layers 2 and 1 of the OSI model. It is what determines what networking protocol a device will use on the network and is responsible for converting the network bits into an electrical signal. RADIUS is an AAA protocol used to authenticate end users. It has very robust Accounting features. TACACS+ is a AAA protocol used to authenticate end devices. It encrypts all transmissions between devices.

Summary

RAS is a description of the combination of software and hardware required for a remote access connection (its not a protocol). Web services are used to allow disparate software or platforms to communicate. They will usually translate communication into an XML format that most software can understand. Unified voice services is a description of the combination of software and hardware used to bring voice communication into a network.
