PPP |
Point-to-Point Protocol is a data link protocol used to establish a direct connection between twonodes. It can provide connection authentication, transmission encryption data link layer encapsulation protocol |
|
|
TCP/IP Physical layer |
Bit transmission the physical layer encodes a signal onto the medium to transmit the frame Standard: RJ-45, Ethernet (IEEE 802.3) Devices: LAN hub, LAN repeater, cables |
|
|
TCP/IP Data Link layer |
Encapsulate the data supplied by the network layer inside a data link layer head and trailer. This layer uses both headers and trailers. Type: Frame Protocol/Standard : Ethernet (IEEE 802.3), HDLC Devices: LAN switch, wireless access point, cable modem, DSL modem |
|
|
TCP/IP Network layer |
Encapsulate the data supplied by the transport layer inside a network layer (IP) header. IP defines the IP addresses that uniquely identify each computer. Type: Packet Protocol: IP Devices: Router |
|
|
TCP/IP Transport layer |
Encapsulate the data supplied by the application layer inside a transport layer header. For end-user applications a TCP or UDP header is typically used. Type: Segment Devices: Hosts, firewalls |
|
|
TCP/IP Application layer |
Create and encapsulate the application data with any required application layer header. For example HTTP Ok message can be returned in a an HTTP header, followed by part of the contents of a web page Protocols: telnet, HTTP, FTP, SMTP, POP3, VoIP, SNMP Devices: Hosts, firewalls |
|
|
OSI Application layer |
This layer provides an interface between the communicate outside the computer on wich the application resides it also defines processes for the user authentication |
|
|
OSI Presentation layer |
This layer's main purpose is to define and negotiate data formats such as ASCII text, EBCDIC text, binary, BCD, and jpeg. Encryption is also defined by OSI as a presentation layer service |
|
|
OSI Session layer |
This layer defines how to start, control, and end conversations (called sessions). This includes the control and management of multiple bidirectional messages so that the application can be notified if only some of a series of messages are completed. This allows the presentation layer to have a seamless view of an incoming stream of data |
|
|
OSI Transport layer |
This layer's protocols focuses on issues related to data delivery to another computer (for example error recovery and flow control |
|
|
OSI Network layer |
This layer defines three main features: logical addressing, routing (forwarding), and path determination routing defines how devices (typically routers) forward packets to their final destination. Logical addressing defines how each device can have an address that can be used by the routing process. Path determination refers to the work done by routing protocols to learn all possible routes and choose the best route. |
|
|
OSI Data link layer |
This layer defines rules that determine when a device can send data over a particular medium. Data link protocols also define the format of a header and trailer that allows devices attached to the medium to successfully send and receive data. |
|
|
OSI Physical layer |
This layer typically refers to standards from other organizations. These standards deal wi th physical characteristics of the transmission medium, including connecters, pins, use of pins, electrical currents, encod8ng, light modulation, and rules for how to activate and deactivate the use of the physical medium |
|
