The VDL Mode 2 Link Layer is made up of two sublayers, a data link service and a media access control ( MAC ) sublayer.
22.
At the Media Access Control ( MAC ) layer, VLAN IEEE 802.1Q and IEEE 802.1p can be used to distinguish between Ethernet frames and classify them.
23.
On top of these two physical layers, two different Media Access Control ( MAC ) layers were defined; one for In-home networking and the other for Internet access.
24.
However, the media access control ( the multiple access protocol ) is Dynamic TDMA in HiperLAN / 2, while CSMA / CA is used in 802.11a / n.
25.
As an example, PD-SAP or PLME-SAP in IEEE 802.15.4 can be mentioned, where the Media Access Control ( MAC ) layer requests certain services from the Physical Layer.
26.
"' IEEE 802.11 "'is a set of media access control ( MAC ) and physical layer ( PHY ) specifications for implementing MAN Standards Committee ( IEEE 802 ).
27.
This requires a media access control ( MAC ) protocol, i . e . a principle for the nodes to take turns on the channel and to avoid collisions.
28.
"' Advantages "': The MAC layer is simplified because the P2P connections between OLT and ONUs are realized in wavelength domain, so no P2MP media access control is needed.
29.
:: Usually there will be a list of devices that have connected to the modem recently, they will list something called a MAC ( Media Access Control ) address.
30.
"' Carrier sense multiple access with collision detection "'( "'CSMA / CD "') is a media access control method used most notably in early Ethernet technology for local area networking.
