The ICMP packet format is 8-bit type + 8-bit ** + 16-bit verification and +ICMP data area, in which the 8-bit type represents different ICMP functions, including 8 kinds of query packets and 5 kinds of error control packets

Type 3 Destination unreachable (network unreachable, host unreachable, protocol unreachable, port unreachable......(16 types in total, expressed in 8bit** bits).

Type 4 Origin server suppression.

Type 5 Route Control and Redirection (4 types of redirection to network, redirection to host, redirect to service type and network, 4 types of service type and host redirection).

Type 11 timeout (i.e. time-to-live TTL of 0).

Type 12 parameter error (IP data reporting error, missing required options).

· No ICMP error report packets are sent to ICMP error report packets.

No ICMP error report packets are sent to all subsequent data messages of the first fragment.

No ICMP error report packets are sent to datagrams with multicast addresses.

There are two commonly used ICMP interrogation packets, namely:

1) Loopback Request and Answer ICMP Loopback Request packets are inquiries sent by a host or router to a specific destination host. The host that receives the packet must send an ICMP backhaul reply packet to the source host or router. This interrogation message is used to test whether the destination station is reachable and to know its status.

2) Timestamp Request and Answer: The ICMP timestamp request packet asks a host or router to reply with the current date and time. In the ICMP timestamp answer packet, there is a 32-bit field in which an integer is written representing the number of seconds from January 1, 1900 to the current time. Timestamp requests and answers can be used for clock synchronization and time measurement.

22 questions choose C. This question examines definite clauses. The antecedent is rate, which refers to "speed, ratio", here the definite clause guided by the preposition plus the relative pronoun, the preposition is placed in front of the relative pronoun, so it is impossible to use that for the relative pronoun, and furthermore, the preposition at is used here with the rate to indicate that according to.
