Figure A 1 Ipv4 Header The Field Service Type Is Also Known As The Download scientific diagram | figure a.1: ipv4 header, the field "service type" is also known as the type of service (tos) field. from publication: quality of service considerations for network. Students also studied. the type of service field actually has two components: precedence and . how many possible fields can be contained in an ipv4 header?.
Figure A 1 Ipv4 Header The Field Service Type Is Also Known As The The size of this field is also 32 bits. this field stores the ipv4 address of the destination device. options. this field stores ipv4 options. the size of this field is a multiple of 32 bits. if an option is not 32 bits in the length, it uses padding options in the remaining bits to make the header an integral number of 4 byte blocks. The ipv4 header needs to contain the following information: destination and source addresses. indication of ipv4 versus ipv6. a time to live (ttl) value, to prevent infinite routing loops. a field indicating what comes next in the packet (eg tcp v udp) fields supporting fragmentation and reassembly. the header is organized as a series of 32 bit. The minimum length of an ip header is 20 bytes so with 32 bit increments, you would see value of 5 here. the maximum value we can create with 4 bits is 15 so with 32 bit increments, that would be a header length of 60 bytes. this field is also called the internet header length (ihl). type of service: this is used for qos (quality of service. Ipv4 could be a numeric address, and its bits are separated by a dot. the number of header fields is twelve and the length of the header field is twenty. it has unicast, broadcast, and multicast style of addresses. ipv4 supports vlsm (virtual length subnet mask). ipv4 uses the post address resolution protocol to map to the mac address.

Type of service. the type of service (tos) field is the second byte of the ipv4 header. it has had various purposes over the years, and has been defined in different ways by five rfcs. [1] prior to the redefinition, the tos field could specify a datagram's priority and request a route for low latency, high throughput, or highly reliable service. The internet header length (ihl) field is the number of 32 bit words (=4 bytes) in the ipv4 header, including any options. because this is also a 4 bit field, the ipv4 header is limited to a maximum of fifteen 32 bit words (=60 bytes) so if the value of ihl is 0101 (5), then the ip header's length is 5*4 (bytes) = 20 (bytes).
