Rapid startup and Emergency Call Service Location Identification Discovery of
endpoints is a critically important aspect of VoIP systems in general. In addition, it is
best to advertise only those pieces of information which are specifically relevant to
particular endpoint types (for example only advertise the voice network policy to
permitted voice-capable devices), both in order to conserve the limited LLDPU
space and to reduce security and system integrity issues that can come with
inappropriate knowledge of the network policy.
With this in mind LLDP-MED defines an LLDP-MED Fast Start interaction between
the protocol and the application layers on top of the protocol, in order to achieve
these related properties. Initially, a Network Connectivity Device will only transmit
LLDP TLVs in an LLDPDU. Only after an LLDP-MED Endpoint Device is detected,
will an LLDP-MED capable Network Connectivity Device start to advertise
LLDP-MED TLVs in outgoing LLDPDUs on the associated port. The LLDP-MED
application will temporarily speed up the transmission of the LLDPDU to start within
a second, when a new LLDP-MED neighbor has been detected in order share
LLDP-MED information as fast as possible to new neighbors.
Because there is a risk of an LLDP frame being lost during transmission between
neighbors, it is recommended to repeat the fast start transmission multiple times to
increase the possibility of the neighbors receiving the LLDP frame. With Fast start
