As an organisation’s bandwidth requirements fluctuate based on seasonal demand, special events, or unpredictable spikes, traditional fixed-bandwidth solutions often fall short. This is where burstable bandwidth, a pivotal feature in leased line internet connections, proves its value.
Burstable bandwidth allows businesses to temporarily exceed their committed data rate during periods of peak demand. It empowers organisations to handle traffic spikes seamlessly without investing in costly permanent bandwidth upgrades. Airtel’s Internet Leased Line (ILL) harnesses burstable bandwidth to help businesses scale their internet usage dynamically. This approach ensures both optimal performance and cost-efficiency.
What Is Burstable Bandwidth?
Burstable bandwidth lets businesses exceed their regular leased line speed temporarily during peak usage times. Here is how it works:
- Baseline Bandwidth: The minimum assured bandwidth a business subscribes to as part of its leased line internet connection.
- Burstable Capacity: The additional bandwidth available during peak usage, generally up to a predefined maximum (e.g., 5x the baseline).
- 95th Percentile Billing: Businesses are charged for extra usage based on the 95th percentile rule, which excludes the top 5% of traffic spikes, ensuring fair billing.
This dynamic bandwidth allocation ensures businesses can handle sudden surges in internet traffic without experiencing performance dips or costly overages.
Benefits of Burstable Bandwidth for Businesses
Integrating burstable bandwidth into leased line services offers several key advantages for organisations:
- Cost-Effectiveness: By paying for additional bandwidth only when needed, businesses can avoid the expense of permanently upgrading their leased line internet connection.
- Scalability: Burstable bandwidth enables organisations to scale their internet capacity on-demand, accommodating growth and fluctuating requirements without infrastructure changes.
- Improved User Experience: By seamlessly handling traffic spikes, businesses can ensure a consistent, high-quality user experience for their customers and employees.
- Flexibility: Burstable bandwidth provides the agility to adapt to changing business needs, such as seasonal demand, special events, or temporary projects.
