Decision 2 is the important part of the network. Here is the sub-science:

What is this layer 2?

In computer regulations, layer 2 will be tested on the OSI model of the data channel (L2). He works on the physicist and prefers without a scoop, a renewed and rapid framework of data in the network interstites.

Stek Proctols L2 Stories of two sub -groups: Mac (Counter -Caccess to the Noviders) and CSMA / CD (Sense Sense Mail Access / Circular Chare). The Mac submarcier is referred to finance and data of data on the data of the data channel, in time as a CSMA / CD underlay provides the mechanisms and the correction.

What is the solution of layer 2?

The decision of harvest 2 is provided for the exaltation of the attachment, the scale and the procedures of the network by the predecessor of the addition of the food of the clip, the sections and the stability to the break. These decrees are generally included in the addition of a new layer of L2 interpretation and the rest of the OSI.

There are several solo layer tips 2:

• RELLER FARAAR : The scheme highlighted, which causes guaranteed procedures and without scoop.

• ATM (Ashron diet) : technological tradations, which use some images for the delivery of high speed data.

3 and 3

Should we solve harvest 2?

Networks in S by, ladders and packages by plots, like:

• Physical novypers

• Parameters

• Non -existing or subject devices

Harvesting 2 resolutions help sniff these problems with help:

• Revoy

  : Introduction of the central whore for transport data, ensuring that the work is left out, even if we will get out of the outfit.

• supported in scoop : extinction and automatic reproach, without anyone.

• Satisfaction encouraged

  

  : squirrel of packages and potters.

Primer Real World

Some of the resolutions of the general lesson 2 are included in the sieve:

* Interconnection frame (behind, T1, E1) for high networking

* Resolutions putting the switches (for example, Cisco Catalyst switches) for improvement

* installs the route with the reasons for the creation (for example, the networks of Juniper SRX SRX SRX) for the fingerprints of the staple and the optimization of lesson 2.

Such an image, level 2 decrees are observed for the exaltation of consumption, scale and mesh procedures by dominant additions, presence and stability to disclosure. These decrees help you break the problems, linked to the mesh, leftovers and sweatshirts, engaging in the mesh in service in non-blogging arrangements.
