18. (a) Two networks are said to be adjacent if there is at least one link directly between them. A network is said to be reachable from another network if there is a path between them. Reachability is one-way. Two networks are said to be connected if there is a path between them that provides reachability in both directions. (Source : Nevil Brownlee and Chris Loosley 2001, www.keynote.com), and (b) Active measurements are performed by sending test traffic into the network while passive measurements are carried out by observing normal network traffic so they do not perturb the network.

(a) It is a ratio of total distal capacity to proximal capacity, total distal capacity being average customer capacity of access provider and proximal capacity being the capacity of transport provider, (b) Time delay in an event to take place, for example, time taken by a packet to travel along the physical links. A widely used measure of network latency is round-trip time (RTT), (c) Throughput for the link expressed as a percentage of access rate, throughput being the rate at which data is sent through the network and access rate being maximum data rate (Rates are measured in terms of bits / bytes / packets per second ), (d) Coined by Cindy Bickerstaff, it is undue focus on a single measured value, and (e) Packet Internet Groper, a utility to determine whether a specific Internet protocol (IP) address is accessible. Ping sends an Internet control message protocol (ICMP) echo request packet to a specified (server) host, and the server sends back an ICMP echo reply packet. The ping program displays the time taken for the round trip. (Source: http://www.keynote.com and Margolis 1999).
