xin giúp đỡ về MTU
Suppose a TCP message that contains 2048 bytes of data and 20 bytes of TCP
header is passed to IP for delivery across two networks of the Internet (i.e., from
the source host to a router to the destination host). The first network uses 14-byte
headers and has an MTU of 1024 bytes; the second uses 8-byte headers with an
MTU of 512 bytes. Each network’s MTU gives the size of the largest IP datagram
that can be carried in a link-layer frame. Give the sizes and offsets of the sequence
of fragments delivered to the network layer at the destination host. Assume all IP
headers are 20 bytes.
thanks all.
