The PADO packet contains the MAC address of the DSL-AC, its name (e.g. LEIX11-erx for the T-Com DSL-AC in Leipzig) and the name of the service. If more than one POP's DSL-AC replies with a PADO packet, the user's computer selects the DSL-AC for a particular POP using the supplied name or service. Here is an example of a PADO packet:
Packet Tracer is commonly used by NetAcad students, since it is available to download after creating a free account. [10] However, due to functional limitations, it is intended by Cisco to be used only as a learning aid, not a replacement for Cisco routers and switches . [ 9 ]

The loss of packet flow samples results in a slight reduction of the effective sampling rate. The UDP payload contains the sFlow datagram . Each datagram provides information about the sFlow version, the originating device’s IP address , a sequence number, the number of samples it contains and one or more flow and/or counter samples.
In computer networking, telecommunication and information theory, broadcasting is a method of transferring a message to all recipients simultaneously. Broadcasting can be performed as a high-level operation in a program, for example, broadcasting in Message Passing Interface, or it may be a low-level networking operation, for example broadcasting on Ethernet.
Internet Protocol Flow Information Export (IPFIX) is an IETF protocol, as well as the name of the IETF working group defining the protocol.
