An alternative solution, introduced by many of the network manufacturers in the early 1990s, is to use link aggregation to combine two physical Ethernet links into one logical link. Most of these early solutions required manual configuration and identical equipment on both sides of the connection. [4]
In wired networks, the hop count refers to the number of networks or network devices through which data passes between source and destination (depending on routing protocol, this may include the source/destination, that is, the first hop is counted as hop 0 or hop 1 [1]). Thus, hop count is a rough measure of distance between two hosts.
In a lab at DEC they knew how many bits their repeaters would lose and knowing this were able to create an 11 segment, 10 repeater, 3 active segment (11-10-3) network that maintained a round trip delay of less than 51.2 μs and a sufficient number of preamble bits that all end nodes functioned properly.

The need for hosts to be able to detect collisions limits the number of hubs and the total size of a network built using hubs (a network built using switches does not have these limitations). For 10 Mbit/s networks built using repeater hubs, the 5-4-3 rule must be followed: up to five segments (four hubs) are allowed between any two end ...
Two telephones can make only one connection, five can make 10 connections, and twelve can make 66 connections. Metcalfe's law states that the financial value or influence of a telecommunications network is proportional to the square of the number of connected users of the system ( n 2 ).
As a result, many network architectures limit the number of repeaters used in a network, e.g., the Ethernet 5-4-3 rule. An Ethernet repeater with multiple ports is known as an Ethernet hub. In addition to reconditioning and distributing network signals, a repeater hub assists with collision detection and fault isolation for the network.
The Max TCP Window size in the absence of TCP window scale option is 65,535 bytes. Example: Max Bandwidth = 65,535 bytes / 0.220 s = 297886.36 B/s * 8 = 2.383 Mbit/s. Over a single TCP connection between those endpoints, the tested bandwidth will be restricted to 2.376 Mbit/s even if the contracted bandwidth is greater.
Distance-vector routing protocols use the Bellman–Ford algorithm.In these protocols, each router does not possess information about the full network topology.It advertises its distance value (DV) calculated to other routers and receives similar advertisements from other routers unless changes are done in the local network or by neighbours (routers).
