Problems with Mobile IP
nSecurity
–authentication
with FA problematic, for the FA typically belongs to another organization
–no protocol
for key management and key distribution has been standardized in the Internet
–patent and
export restrictions
nFirewalls
–typically
mobile IP cannot be used together with firewalls, special set-ups are needed (such as reverse tunneling)
nQoS
–many new
reservations in case of RSVP
–tunneling
makes it hard to give a flow of packets a special treatment needed for the QoS
nSecurity, firewalls, QoS etc. are topics of current
research and discussions!
