An Internet service provider network is a system that provides Internet access to users. There are some downsides to ISP, mainly revolving around the potential downtimes that could delay critical processes in sectors like healthcare, where this has detrimental consequences.
What is an ISP network?
ISPs use various types of technology like fiber optics, cable, DSL, and satellite, to deliver data. The network consists of physical hardware as well. This includes servers, routers, and data centers. ISPs serve as intermediaries, connecting individual users and organizations to larger networks or directly to the internet backbone.
According to a chapter from the Guide to Reliable Internet Services and Applications, “In large carrier networks, the IP Backbone is not a self-contained entity; it co-exists with numerous access and transport networks operated by the same or other service providers.” Its function is to control necessary aspects of internet access, including bandwidth, speed, and reliability.
How does it work
- ISPs provide internet access to homes, businesses, and organizations.
- They use technologies like fiber optics, DSL, cable, or satellite to deliver data.
- ISPs connect customers to larger networks or the global internet backbone.
- Physical hardware like routers, servers, and data centers manage data flow.
- Bandwidth and speed are controlled to ensure reliable service.
- Data from users travels through access networks, metro networks, and core networks.
- Points of Presence (PoPs) serve as hubs for data routing between regions.
- ISPs maintain infrastructure to manage traffic and handle outages.
- Protocols like MPLS optimize routing and improve network efficiency.

The challenges faced by ISP networks in healthcare
ISPs can support healthcare communication by allowing for the necessary infrastructure for the transmission of secure HIPAA compliant emails. There are however prominent challenges with the application of ISPs in healthcare as prevalent with many internet protocols.
These include:
- ISPs can be targets for cyberattacks like DDoS attacks, hacking, or breaches.
- Many ISPs do not automatically offer HIPAA email or other secure services.
- ISP outages or service interruptions can disrupt business operations.
- Some ISPs may have limitations on bandwidth or speed, especially in rural or underserved areas.
- ISPs may throttle data speeds for high usage customers or during peak hours.
- While ISps often provide SLAs to guarantee a certain level of performance, these can be insufficient or ambiguous compared to comprehensive Business Associate Agreements.
FAQs
What is TCP?
TCP is a transmission control protocol, that breaks data into small packets, sends them, and ensures they arrive safely.
What are IPs?
Internet protocols are addresses that help devices find each other on a network. Every device connected has an IP address either:
- IPv4: Older styles that look like 192.168.0.1
- IPv6: Newer, longer format, like 2001:0db8:85a3::8a2e:0370:7334
What are system networks?
Groups of devices are connected to share resources like printers or the internet. They can range from small setups, like WiFi, to massive ones, like the internet itself. Types of system networks include:
- Local area network
- Wide area network
- WiFi
