Fundamental
TCP Throughput Estimate (Mathis Formula)
Throughput ≈ (MSS * C) / (RTT * sqrt(p))
Fundamental
Nyquist Bit Rate (Noiseless Channel)
C = 2*B*log2(L)
Fundamental
Round Trip Time (Transmission + Propagation)
RTT = 2*(T_trans + T_prop)
Fundamental
Packet Transmission Time
T_trans = Packet Size / Link Bandwidth
Fundamental
Number of Subnets from CIDR Prefix
Subnets = 2^(new_prefix - original_prefix)
Fundamental
Bandwidth-Delay Product
BDP = Bandwidth * RTT
Fundamental
Subnet Hosts from CIDR Prefix
Usable Hosts = 2^(32-prefix) - 2
Fundamental
Little's Law (Queuing)
L = λW
Fundamental
Shannon-Hartley Channel Capacity
C = B·log₂(1+S/N)
