The ones indicate bits in the address used for the network prefix and the trailing block of zeros designates that part as being the host identifier. The following example shows the separation of the network prefix and the host identifier from an address (192.0.2.130) and its associated / 24 subnet mask (255.255.255.0). The operation is ...
The dotted decimal portion is the IPv4 address. The number following the slash is the prefix length, the number of shared initial bits, counting from the most-significant bit of the address. When emphasizing only the size of a network, the address portion of the notation is usually omitted.
Reasons for measuring throughput in networks. People are often concerned about measuring the maximum data throughput in bits per second of a communications link or network access. A typical method of performing a measurement is to transfer a 'large' file from one system to another system and measure the time required to complete the transfer or ...
A broadcast address is a network address used to transmit to all devices connected to a multiple-access communications network. A message sent to a broadcast address may be received by all network-attached hosts. In contrast, a multicast address is used to address a specific group of devices, and a unicast address is used to address a single ...
In a small network such as a home or home office, a default route is often used to send all traffic to the user's Internet service provider. Likewise, medium-sized networks such as branch offices or small Internet service providers may use default routes for traffic intended for the public Internet. But in medium-sized and large networks ...
Network performance could be measured using either active or passive techniques. Active techniques (e.g. Iperf) are more intrusive but are arguably more accurate. Passive techniques have less network overhead and hence can run in the background to be used to trigger network management actions.
The most common network type in which backhaul is implemented is a mobile network. A backhaul of a mobile network, also referred to as a mobile-backhaul connects a cell site towards the core network. The two main methods of mobile backhaul implementations are fiber-based backhaul and wireless point-to-point backhaul. [2]
The checksum calculation is defined as follows: [5] The checksum field is the 16 bit one's complement of the one's complement sum of all 16 bit words in the header. For purposes of computing the checksum, the value of the checksum field is zero.
