Which is better LLC or VC-MUX?
As its name suggests, VC-MUX can handle more data quicker than LLC. The big difference here is the “agreement” among the systems on any specific network. 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.
What is connection type LLC and VC-MUX?
In VC Multiplexing (VC-MUX), the hosts agree on the high-level protocol for a given circuit. It has the advantage of not requiring additional information in a packet, which minimises the overhead. In LLC Encapsulation the hosts use a single virtual circuit for multiple protocols.
What is encapsulation VC-MUX?
Virtual circuit multiplexing or VC-MUX is one of the two (the other being LLC encapsulation) mechanisms for identifying the protocol carried in ATM Adaptation Layer 5 (AAL5) frames specified by RFC 2684, Multiprotocol Encapsulation over ATM.
What is PPPoA VC-MUX?
Point-to-Point Protocol over Asynchronous Transfer Mode (PPPoA) is specified by The Internet Engineering Task Force (IETF) in RFC 2364. This is because it uses headers that are short so imposes minimal overheads, 2 bytes for PPP and 8 bytes for PPPoA (with the RFC2364 VC-MUX option) = 10 bytes.
What is my VPI and VCI?
The VPI, together with the VCI (Virtual Channel Identifier) is used to identify the next destination of a cell as it passes through a series of ATM switches on its way to its destination. VPI is useful to reduce the switching table for some Virtual Circuits which have common path.
What is ATM LLC bridged?
What is it ? ATM bridging (RFC2684) is mainly use in the scope of xDSL connections. It provides a convenient way to extend ethernet facility over ATM. The RFC 2684 “describes two encapsulations methods for carrying network interconnect traffic over AAL type 5 over ATM”.
What is VPI and VCI?
VPI—The Virtual Path Identifier is an 8- or 12-bit field used to identify paths between sites on the ATM network. VCI—The Virtual Connection Identifier is a 16-bit field used to identify paths between individual devices on the ATM network.
How does PPPoE work?
PPPoE uses standard methods of encryption, authentication, and compression specified by PPP. PPPoE is configured as a point to point connection between two Ethernet ports. Request – Upon receipt of the PADO packet, the client responds by sending a PPPoE Active Discovery Request (PADR) packet to the server.
What is VCI number?
Stands for “Virtual Channel Identifier.” The VCI, used in conjunction with the VPI (virtual path indicator), indicates where an ATM cell is to travel over a network. ATM, or asynchronous transfer mode, is a method that many ISPs (Internet Service Providers) use to transfer data to client computers.
What is VPI and VCI in ATM?
VPI—The Virtual Path Identifier is an 8- or 12-bit field used to identify paths between sites on the ATM network. It is larger on the NNI to accommodate aggregation on customer paths. • VCI—The Virtual Connection Identifier is a 16-bit field used to identify paths between individual devices on the ATM network.
What’s the difference between a VC-MUX and a LLC?
LLC is a slightly older, slower network protocol. It is a method of sending and receiving data throughout a computer network. It is a more complex “packet” of data in that it must specify the nature of the translation process.
When do you use VC-MUX and PPPoE?
Virtual Circuit Multiplexing or VC-MUX is a form of network traffic control. 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. VC-MUX is commonly used in conjunction with PPPoE and PPPoA.
Is there a VC MUX for WiFi or Ethernet?
According to the IEEE 802 family of standards (Ethernet, WiFi, etc), in VC Multiplexing (VC-MUX), each ATM Virtual Circut (VC) carries PDUs of exactly one protocol type. When multiple protocols need to be transported, there is a separate VC for each.
What kind of data can a VC-MUX send?
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 2011, most computing networks use a combination of the two forms of data transport, depending on the clients and the nature of the network.
