What happens to an ip datagram when it reaches 0?
what happens to a packet if the TTL field reaches 0 I dont believe a datagram reaches O because once the datagram reaches 1 the router or device discards it.I banged ur mom she sucked this stick B-----D
Which portion of a received datagram is decoded and used by the internetwork layer of the tcpip model?
Only the Network Layer (Layer 3) portion of the datagram is used by the Network Layer (Layer 3) portion of the TCP/IP Model. The network portion of the datagram includes IP Addressing information, and things such as TTL (Time to Live), and Datagram Priority markings.
What happen to an IP datagram when its TTl reachs 1?
It is discarded by the connectivity device. network + Guide to networks pg 164
What is the line of business of TTL?
TTL in the ISO/OSI Stack (IP Networks) ======================= TTL (Time To Live) is the time a message has to live given in hops. Each time the package is forwarded this counter counts down. With the TTL one avoids a datagram being routed in circles and cloaking the "intertube"'s up.
The maximum size of an IP datagram including the header is?
The datagram length field in an IP header is 16 bits in length. Therefore, the maximum datagram size an IP datagram can support is 2^16 - 1 = 65,535 bytes
In the context of tcpip a packet is also known as?
IP Datagram
What are the primary subdivision of an IP datagram?
data, and header
The datagram length field in an IPv4 datagram contains which numeric value?
Total number of bytes in the datagram, including the header.The length of an IP datagram itself is technically measured in bytes. The length field represents the size of both the header and the data portions of the datagram.
Which IP packet field wiil prevent endless loops?
Time -to-live
What is IP datagram fragmentation and MTU?
IP datagram can be used to describe a portion of IP data. Each IP datagram has set of fields arranged in an order. The order is specific which helps to decode and read the stream easily. IP datagram has fields like Version, header length, Type of service, Total length, checksum, flag, protocol, Time to live, Identification, source and destination ip address, padding, options and payload. MTU:- Maximum Transmission Unit is the size of the largest packet that a communication protocol can pass. The size can be fixed by some standard or decided at the time of connection Fragmentation is a process of breaking the IP packets into smaller pieces. Fragmentation is needed when the datagram is larger than the MTU. Each fragment becomes a datagram in itself and transmitted independently from source. When received by destination they are reassembled.

Which field of ip address is changes from router to router?
The TTL will be reduced by one every time it passes a router. Because this changes the IP header, the checksum also has to be recalculated.The TTL will be reduced by one every time it passes a router.
