Re: [RRG] Re: [RAM] Tunneling overheads and fragmentation
In practice, this is not really a problem. Hosts typically do not
originate IP packets larger than 1500 bytes. And second, a survey
has been taken (from a list of ISPs, see Acknowledgement section)
where nearly all ISP link MTUs are either 4470 bytes or support
Ethernet jumbo frames of 9000 bytes. Therefore, we don't
any problems with prepending additional headers.
What this really presupposes is that all ITR/ETRs will end up at
large service provider sites.
If an ITR/ETR ends up as a CE device or embedded in a larger site,
then I don't see how this
to unsubscribe send a message to email@example.com with the
word 'unsubscribe' in a single line as the message text body.
