bitrate by Life time of segment

Question

In a network that has a max TPDU size of 128 bytes, a maximum of TPDU lifetime of 30 sec, and 8-bit sequence number, what is the maximum data rate per connection?

Please help me to understand this problem.

Answer 1

8 bit sequence no hence it can send max od 2⁸ segments in lifetime hence segment sending rate is 256/30 segment/s

TPDU is 128 Byte hence total rate is 128 *8*256/30= 8738.33 bps

Comments

but sequence number is given to each byte rather than each segment right?

yes………..so confusing!!!
