LLC is a slightly older, slower network protocol. It is a method of sending and receiving data throughout a computer network. It is designed to maximize the accuracy of the data transferred, though it is slower than its main rival and harder to maintain since it contains more actual information than VC-MUX.
This means that all systems must agree on the specific nature of the data translation method. Put differently, the VC-MUX can send many different kinds of data under a single protocol, so long as all the units in the system agree on what that is. As of , most computing networks use a combination of the two forms of data transport, depending on the clients and the nature of the network.
It requires the Internet service provider, for example, to pre-program all their DSL boxes to receive one and only one encoding and decoding method. On the other hand, a LLC method will program this method in the data itself. If it is used as the connection encapsulation method on an ATM based network it can reduce overhead slightly around 0. It is used in situations where multiplexing is preferable to switching.
Multiplexing is used when there's a need to transport multiple data streams over a single data link. Which are used in various xDSL implementations. When multiple protocols need to be transported, there is a separate VC for each. It is used mainly with ADSL services. Unfortunately it has an MTU lower than that of standard Ethernet which can sometimes cause problems with badly configured firewalls. PPPoE is a tunneling protocol which allows layering IP, or other protocols that run over PPP, over a connection between two Ethernet ports, but with the software features of a PPP link, so it is used to virtually "dial" to another Ethernet machine and make a point to point connection with it, which is then used to transport IP packets, based on the features of PPP.
It allows the use of traditional PPP-based software to handle a connection which does not use a serial line, but a packet-oriented network like Ethernet, to provide a classical connection with login and password for Internet connection accounting.
The protocol is specified in RFC PPPoA uses ATM encapsulation,which has lower overhead than ethernet because most of these isp's use still use ATM bbones,which might be basically the reason u might get a bit more speed although not substantial. Amol Adept.
