Renewal of the Active Network Infrastructure
As part of this project, the existing active network infrastructure was modernized and made fit for the future. The goal was to introduce a powerful, secure and scalable network and WLAN infrastructure, including a Network Access Control (NAC) solution to improve network security and centralized access control.
At the beginning of the project, a comprehensive requirements analysis was carried out, taking into account the technical, operational and security-related requirements of the hospital sites. On this basis, a technical tender was prepared for new switches, WLAN access points and the NAC solution.
The successful implementation of the project established a modern, standardized and secure network infrastructure that meets the growing requirements for availability, mobility and IT security in hospital operations.
Activities:
- Supporting the tender process, including technical evaluation of offers and bidder evaluation
- Leading and managing the entire project implementation
- Coordinating the project process with internal stakeholders, business units and hospital IT
- Managing external service providers during the implementation and installation of the systems
- Monitoring the implementation, including quality control, project acceptance and defect management
- Coordinating and managing communication between hospital IT and external service providers as part of the NAC implementation
- Managing escalations in the event of technical and organizational challenges
- Ongoing budget monitoring and control of project expenses and additional costs
- Preparing decision papers for management on project changes, additional services and risks

Information Security & GRC Expert at GLG (Gerson Lehrman Group)
As a Council Member at GLG (Gerson Lehrman Group), the world’s leading expert network, I provide organizations, investment firms, and consulting companies with expert discussions on demand – wherever specialized knowledge in information security, IT governance, and regulatory compliance is needed.
My assessments are based on many years of practical experience in highly regulated industries: from building and implementing information security management systems (ISMS according to ISO 27001), IT risk and vulnerability management, and business continuity (ISO 22301) to the practical implementation of European regulations such as DORA, NIS2, BAIT, and the Cyber Resilience Act (CRA).
The cooperation is project- and discussion-based. I provide decision-makers with a practical perspective gained from real-world experience on cyber risks, security governance, and operational resilience – exactly when it is needed.

About the technology
What Quality of Service means
Quality of Service, commonly called QoS, controls how network traffic is treated when bandwidth, latency or reliability becomes constrained. It prioritizes sensitive flows such as voice, video, control signals and transactional data instead of allowing every packet to compete equally. The goal is predictable application performance, not simply higher bandwidth.
Where QoS is used
QoS appears wherever network behavior affects business operations, user experience or safety. Typical delivery areas include:
- Voice and unified communications with controlled delay and jitter
- Video conferencing, streaming and interactive collaboration
- Industrial, transport and building-control networks
- Cloud connectivity, SD-WAN and hybrid enterprise networks
- Wi-Fi networks serving high-density or mobile users
Methods and standards
Specialists work with classification, marking, queuing, scheduling, shaping and policing. DiffServ uses DSCP values to assign traffic classes, while IntServ and RSVP reserve resources for defined flows. QoS policies may also span MPLS, IP routing, Ethernet, Wi-Fi and provider edge networks, with careful mapping between each domain.
Tools and adjacent skills
Effective QoS work combines packet analysis with practical network operations. Experts use tools such as Wireshark, NetFlow or IPFIX, router and switch telemetry, synthetic tests and vendor policy frameworks. They often bring related knowledge of BGP, OSPF, VLANs, firewalls, multicast, SD-WAN, cloud networking and real-time media protocols.
When companies need specialists
Freelance expertise is useful when traffic problems cross team or provider boundaries, or when a policy must be introduced without disrupting production. Common signals include:
- Voice or video quality changes under load
- Critical applications competing with backups or bulk transfers
- Inconsistent DSCP handling between office, data centre and cloud
- New sites, carriers or SD-WAN links requiring a traffic model
- Monitoring that shows congestion but not its business impact
What strong professionals deliver
A strong specialist begins with application requirements and measured traffic behavior, then translates them into a documented class model and enforceable policy. They validate markings across every network segment, test failure and congestion scenarios, and define monitoring thresholds. In Germany, successful collaboration may be remote for analysis and design, with on-site work reserved for cutovers, surveys or regulated operational environments.
Frequently asked questions
What clients ask us most about Quality of Service — answered in short.
Quality of Service is used to manage traffic when network resources are limited or applications have different performance needs. It can protect voice, video, control traffic and business-critical systems from delay, jitter, packet loss or congestion.
QoS manages competition between traffic classes, while adding bandwidth increases overall capacity. More capacity may reduce congestion, but it does not by itself ensure that latency-sensitive traffic receives consistent treatment during bursts or link failures.
A strong Quality of Service professional usually understands routing, switching, Wi-Fi, firewalls and network monitoring. Experience with DSCP, DiffServ, MPLS, SD-WAN, VoIP and packet analysis is especially useful when policies cross several network domains.
The right level depends on the network scope and risk. QoS work for a single site may focus on classification and queue tuning, while a multi-provider or cloud rollout requires broader design, testing, documentation and change planning.
Much of a Quality of Service engagement can be handled remotely through configuration reviews, telemetry, packet captures and controlled tests. On-site time in Germany can still help with physical surveys, legacy equipment, cutovers or environments where remote access is restricted.
Ask how the specialist will connect application requirements to measurable targets, traffic classes and validation tests. A capable QoS professional should explain trade-offs clearly, verify behavior across network boundaries and leave behind policies, diagrams, monitoring guidance and rollback steps.
Quality of Service based on DiffServ is often preferred for large networks because it groups traffic into classes and scales across many devices. IntServ with RSVP can provide per-flow reservation, but it brings more signaling and state-management complexity.
A QoS specialist should clarify the affected applications, current topology, link constraints, provider handoffs, device capabilities and change controls. They should also agree on baseline measurements and success criteria before changing markings, queues or shaping policies.
The average hourly rate of freelancers in Germany who have used Quality of Service in their recent projects is 97 €, which corresponds to a daily rate of about 775 € based on an 8-hour working day.
Of the freelancers in Germany who have used Quality of Service in their recent projects, 87% hold at least a Bachelor's degree and 67% hold at least a Master's degree.
On average, freelancers in Germany who have used Quality of Service in their recent projects have 24 years of professional experience, with a single engagement typically lasting around 2.9 years.
