Another important qualifier is the server architecture. Some DNS servers provide support for both server roles in a single, "monolithic" program. Others are divided into smaller programs, each implementing a subsystem of the server. As in the classic Computer Science microkernel debate, the importance and utility of this distinction is hotly ...
Differentiated services or DiffServ is a computer networking architecture that specifies a mechanism for classifying and managing network traffic and providing quality of service (QoS) on modern IP networks.
This is a list of notable managed DNS providers in a comparison table. A managed DNS provider offers either a web-based control panel or downloadable software that allows users to manage their DNS traffic via specified protocols such as: DNS failover , dynamic IP addresses , SMTP authentication , and GeoDNS .
The DCell is a highly scalable architecture where a four level DCell with only six servers in cell 0 can accommodate around 3.26 million servers. Besides very high scalability, the DCell architecture depicts very high structural robustness. [13] However, cross section bandwidth and network latency is a major issue in DCell DCN architecture.

Some OpenNIC recursive servers (Tier 2 servers) are known for their high speeds and low latency, relative to other more widely used DNS recursors, [4] as well as their anonymizing or no-logging policies. [5] [6] Many servers offer DNSCrypt. Community volunteers operate Tier 2 servers across a multitude of geographic locations.
InfiniBand is also used as either a direct or switched interconnect between servers and storage systems, as well as an interconnect between storage systems. It is designed to be scalable and uses a switched fabric network topology. Between 2014 and June 2016, [1] it was the most commonly used interconnect in the TOP500 list of supercomputers.
The speed of light imposes a minimum propagation time on all electromagnetic signals. It is not possible to reduce the latency below = / where s is the distance and c m is the speed of light in the medium (roughly 200,000 km/s for most fiber or electrical media, depending on their velocity factor).
Delay-tolerant networking (DTN) is an approach to computer network architecture that seeks to address the technical issues in heterogeneous networks that may lack continuous network connectivity. Examples of such networks are those operating in mobile or extreme terrestrial environments, or planned networks in space.
