Protocols: The protocols are standard formats for converting data between devices. They determine many aspects of data: error checking, compression types and names of the procedures for sending and retrieving data from the devices. Programmers can choose from a wide variety of standard protocols, each with their advantages and disadvantages. Some are easier than others, some are more reliable and more faster. The key for the user that the device uses the correct protocol to communicate with other ordinateurs.IP
HSRP
Routing Protocols: VRRP
Management Protocol: A network protocol is a set of rules, conventions and formal data structures that govern how computers exchange information over a network. Fruit of years of evolution and development, network protocols are defined by many standards organizations and vendors technologiques.HTTP

Firewall / VPN

VPN tunnels: 20
VPN Protocols: IPSec
VPN Encryption: The standard DES (Data Encryption Standard) is the standard method of data encryption. She uses the key DES56 bits to encrypt and decrypt data.
3DES 168-bit encryption (sometimes called "Triple") is an algorithm that guarantees a higher level of security because it encrypts each data block three times with each time a key unique.DES

Modulation: There are many standards of modulation. The most commonly used are:

DSSS
The standard DSSS (Direct-Sequence Spread Spectrum) is a transmission technology that combines the data signal to a sequence of data bits higher technique called "chipping." This ensures an increased resistance to noise and better data integrity.

OFDM
The standard OFDM (Orthogonal Frequency Division Multiplexing) is to transmit digital data by radio wave by dividing a radio signal into multiple sub-signals. These signalsare then transmitted simultaneously at different frequencies. This modulation technique has the advantage of reducing the crosstalk noise.

CCK
CCK (Complementary Code Keying) uses a sequence of 64 code words 8 bits to encode data. This results in speeds of 5.5 and 11 Mb / s in the 2.4 GHz band of laOFDM
