data link layer การใช้

• Switches work on Layer 2 ( the Data Link Layer ).
• This implies that the throughput often excludes data link layer protocol overhead.
• With this framing only datagram services are supported on the data link layer.
• It is also possible to establish a connection using the data link layer.
• These standards define the physical layer and data link layer of the distribution system.
• VLANs operate at Layer 2 ( the data link layer ) of the OSI model.
• It resides in Layer 2, the Data Link layer, of the OSI model.
• The Data Link Layer is subdivided to include a media access control ( MAC ) sublayer.
• FDMA, on the other hand, is an access method in the data link layer.
• As per the OSI model Ethernet provides services up to and including the data link layer.
• The interface between the Application Entity and the Data Link Layer is called A-interface.
• Brouters operate at both the protocols and at the data link layer for non-routable protocols.
• Some taps operate at the physical layer of the OSI model rather than the data link layer.
• PPP is commonly used as a data link layer protocol for connection over NBF, DECnet and AppleTalk.
• The underlying Data Link Layer almost always poses limits to the maximum frame size ( See MTU ).
• The gateway also operates at the data link layer ( Layer 2 ) of the OSI network model.
• Some approaches utilize both the Network and Data link layer but do not consider the cross layer behaviors.
• The interface between the Data Link Layer and the physical layer is called Medium Independent Interface ( MII ).
• To alleviate these problems, bridging was created to communicate at the data link layer while isolating the physical layer.
• Allowing direct data link layer communication between customer nodes exposes the network to various security attacks, such as ARP spoofing.
