A higher hop count increases the cumulative processing delay, contributing to the overall time delay. A packet traveling through a local network experiences fewer hops and lower time interval than a packet routed across the global internet.
-
Probability of Network Congestion
Longer network paths often involve traversing multiple networks, each with varying levels of congestion. As the number of network segments traversed increases, the probability of encountering a congested link or node also rises. Congestion leads to packet queuing, packet loss, and the need for retransmissions, each contributing to increased time delay. A file download from a server located far away is more likely to be affected by network congestion than a transfer within a local area network.
-
Geographic Routing Inefficiencies
Network routing protocols aim to find the most efficient path between two points, but geographic distance is not always the primary factor considered. Routing decisions are based on network topology, bandwidth availability, and other parameters. It is possible for data to take a longer physical path than the shortest possible route, leading to increased delay. BGP (Border Gateway Protocol) peering arrangements between ISPs can result in geographically circuitous routes, impacting the time interval. Consider, for example, data traveling from one city to another on the same continent but being routed through a third city due to peering agreements.
In conclusion, the physical distance between an Android device utilizing a USB Ethernet adapter and the destination server, or intermediary network nodes, acts as a foundational factor influencing the observed time interval. Propagation delays, increased hop counts, higher probabilities of network congestion, and geographic routing inefficiencies all contribute to higher latency. While minimizing distance is often impractical, understanding its impact is crucial for diagnosing and addressing network delay issues. Techniques such as using content delivery networks (CDNs) or selecting geographically closer servers can mitigate the impact of distance on the overall network performance of Android devices connected via USB Ethernet adapters.
