Comparison

•  Single-homing –  Advantages

•  Cheaper and easier to setup •  Only need to deal with one ISP

–  Challenges •  Availability & reliability •  Performance •  Limited availability of IP address

from the ISP

•  Multi-homing –  Advantages

•  Better availability and reliability •  Load-balancing & traffic engineering

for improved performance •  Better network scalability

–  Challenges •  Networking skill required

Conclusion

•  Most organizations can start with single homing connection as it is simple to set up

•  Organizations that rely heavily on the Internet to run their business should consider a multi-homing connection for better availability, reliability and performance –  Will need to hire a network engineer or get help from a network

integration vendor –  Get their own ASN and IP addresses from APNIC
