On this weblog, we’ll discover why this notion is flawed.
Numerous Community Necessities
Networks differ considerably in scale, complexity, and objective. In consequence, the selection of a NOS is determined by numerous elements, together with the community structure (peer-to-peer versus client-server), the size of the community, and particular necessities equivalent to safety, useful resource administration, and consumer administration.
For instance, a knowledge heart community, designed to handle excessive volumes of site visitors and guarantee dependable knowledge storage and entry, has vastly completely different necessities from a small workplace community, which can prioritize ease of use and minimal setup. Equally, core networks, which type the spine of the web, demand excessive efficiency and robustness, in distinction with edge networks that require low latency and are sometimes tailor-made for particular IoT functions.
Furthermore, completely different NOSs supply various ranges of customization and scalability, catering to organizations’ particular wants. For instance, some use instances, equivalent to peering, require a NOS to assist the total web routing desk (often known as the total border gateway protocol, or BGP, desk) of over 1 million entries—together with quickly relearning the desk and rerouting site visitors within the occasion of a hyperlink or node failure—to make sure complete connectivity and optimum routing selections throughout the worldwide web based mostly on numerous metrics such because the shortest path, least variety of autonomous system (AS) hops, or different policy-based selections. This could result in improved efficiency and decrease latency for finish customers however isn’t important for a knowledge heart community with only some segments.
One other issue is the necessity for the NOS to assist completely different companies based mostly on the use case. Fastened edge networks should be capable to assist a number of companies, equivalent to high quality of service (QoS) for sustaining the efficiency of latency-sensitive functions equivalent to VoIP, video conferencing, and streaming companies, web protocol tv (IPTV) for multicast streaming of high-quality video content material with minimal latency, and carrier-grade community handle translation (CGNAT) for ISPs to optimize current IPv4 infrastructure and delay the funding required for IPv6 deployment. Whereas QoS and IPTV have to be carried by to the aggregation community, CGNAT solely must be achieved as soon as on the edge, affecting the selection of NOS for every use case.
Options and Optimizations Fluctuate by Kind of Community
To fulfill these diverse necessities, every NOS is developed with particular options and optimizations. For instance, a NOS designed for knowledge heart operations would possibly concentrate on virtualization capabilities and high-speed knowledge processing, whereas a NOS for edge computing would prioritize low-latency knowledge processing and light-weight deployment.

Aggregation Networks
- Operate: Aggregation networks accumulate site visitors from entry networks earlier than it’s despatched to the core community, managing site visitors from a number of sources.
- NOS options: NOSs for aggregation networks usually embrace capabilities for site visitors administration, QoS, and assist for medium to excessive knowledge throughput.
Peering Networks
- Operate: Peering networks facilitate the alternate of site visitors between completely different ISPs or giant networks, usually to scale back transit prices and enhance efficiency.
- NOS options: NOSs in peering networks usually have options for BGP routing, site visitors filtering, and safety controls to handle the alternate of routes and knowledge with different networks.
Entry Networks
- Operate: Entry networks join end-user units to the community, serving because the entry level for customers to entry community companies.
- NOS options: Entry community NOSs are designed for managing numerous end-user connections, offering options like DHCP, DNS, and consumer authentication.
Fastened-Edge Networks
- Operate: Fastened-edge networks are designed to ship content material and companies with minimal latency by being nearer to the tip customers.
- NOS options: Fastened-edge community NOSs could embrace options for native knowledge processing, IoT assist, and integration with edge computing platforms optimized for low latency.
Cellular-Edge Networks
- Operate: Cellular-edge networks are a part of the cellular telecommunications infrastructure, designed to deliver computing sources nearer to cellular customers and units.
- NOS options: Cellular-edge NOSs are optimized for the cellular surroundings, supporting options like cellular backhaul, real-time analytics, and seamless integration with cellular community features.
Cloud Networks
- Operate: Cloud networks present scalable and versatile networking capabilities for cloud companies, supporting a variety of functions and companies.
- NOS options: Cloud community NOSs are constructed for virtualized environments, providing options that assist multitenancy, cloud orchestration, and dynamic useful resource allocation.
Tailor-made NOS Options
Since every sort of community has distinct necessities and challenges, the NOS deployed have to be particularly tailor-made to satisfy these wants. For instance, a knowledge heart NOS should deal with the high-density and virtualization calls for of recent knowledge facilities, whereas a core community NOS focuses on high-speed, dependable knowledge transport. Aggregation and peering community NOSs handle site visitors flows and routing exchanges, respectively. Entry community NOSs guarantee connectivity for finish customers, and edge community NOSs (each mounted and cellular) are optimized for delivering companies with low latency. Cloud community NOSs are designed to function in virtualized cloud environments, offering the flexibleness and scalability required for cloud companies.
Safety wants and compliance necessities can even dictate the selection of NOS. Sure environments could require specialised safety features or compliance with particular requirements, influencing the choice of a NOS that may adequately meet these calls for. As well as, open supply NOSs permit customers to switch and adapt the software program to distinctive necessities, which is especially helpful for specialised or evolving community environments.
Selecting the Proper NOS for Your Enterprise
The misbelief that each one NOS are created equal overlooks the nuanced and various panorama of community applied sciences and necessities. Understanding the precise options, capabilities, and optimizations of various NOSs is essential for choosing the precise system to assist a corporation’s distinctive community infrastructure and goals.
GigaOm has simply launched the 2024 NOS Radar experiences throughout three market segments—cellular community operators and community service suppliers (MNOs and NSPs), communication service suppliers and managed service suppliers (CSPs and MSPs), and enormous enterprises and small-to-medium companies (SMBs)—based mostly on technical options and enterprise standards tailor-made to every market phase.
