HNPERF02-BP05 Plan for bandwidth scaling
High-speed dedicated connections can offer bandwidth up to hundreds of gigabits per second. LAG enables bundling multiple physical connections to increase total available bandwidth. Additionally, implementing load balancing across multiple connections using ECMP routing provides enhanced bandwidth scaling and improved reliability. For virtual private network implementations, similar scaling can be achieved by establishing multiple VPN connections and utilizing ECMP to distribute traffic effectively across these paths. Understanding these scaling options and their appropriate use cases is crucial for designing network architectures that can grow with business demands while maintaining performance and reliability.
Desired outcome:
-
Achieve optimal network performance and capacity that meets growing business demands.
-
Scalable network infrastructure capable of increasing traffic volumes
Level of risk exposed if this best practice is not established: High
Benefits of establishing this best practice:
-
Enables strategic bandwidth scaling decisions based on actual business needs while optimizing costs.
-
Provides flexibility to adjust network capacity through various technical approaches as requirements evolve.
-
Load balancing across multiple connections using BGP ECMP, ensuring optimal traffic distribution.
Implementation guidance
-
Assess current and projected bandwidth requirements, considering both peak usage patterns and growth trajectories.
-
Evaluate infrastructure limitations and compatibility at both connection endpoints, including port speeds, hardware capabilities, and routing protocol support.
-
Design for operational efficiency with centralized management, monitoring, and clear maintenance procedures.
-
Consider cost implications and geographical requirements when choosing between scaling approaches, such as dedicated connections vs IPSec VPNs.
