The server S's IP address is 211.68.71.80. H communicates with S based on TCP. Now 5 IP packets are caught in H, and their first 40 bytes in hexadecimal are shown in table 1 as follows, (Note: IP header size is only 20 bytes). Please give complete answers to the next questions above (A and B). (A) According to table 1, please analyze how many application data (bytes) has been received by S? (B) If the first 40 bytes of some IP packet in table 1 when initially sent by S is shown in table 2, how many routers are passed by this packet when arriving at H? Table 2.
