1. What is an expected percentage utilization for a network?
Network Utilization refers to the ratio of the current network traffic to the maximum traffic that can be handled by the port. Else it can also be stated that it is the amount of bandwidth utilized by the network. 50% of the network can be considered to be idle or have a high efficiency. For wide area network or WAN, the average network utilisation is 70 percent. The typical rule states that the average network utilization should not exceed more than 37% for a hub based Ethernet LAN (Biswas et al., 2015).
2. The protocol analyser shows that the average frame size of data packets being delivered to and from the campus network’s Internet connection is 1203. Is this a reasonable average? Justify your answer.
The RFC 2544 was established by the “Internet Engineering Task Force” or IETF. As per the RFC 2544 Benchmark Standards the Connection is considered the best between 1024 to 1518 by the manufacturers of the network equipment and the service providers so according the protocol analyser the interconnection is 1203 which will help in considering the fact that the frame size is the perfect size. RFC 2544 test suite also supports seven predefined frame size and they are 64, 128, 256, 512, 1024, 1280 and 1518 for the purpose of simulation of the different types of network conditions (FlÃ, & Popovski, 2016). The MTU payload is 1203 so the total number of bytes is 1203+8+6+6+2+4= 1229 bytes along with this it also consists of an inter-frame gap of 12 bytes, therefore it can be stated that 1241 is the total number of each frame that is going out of the host. The frame based protocol is mostly used by the LAN but it can also be used by the MAN and WAN network.
