Tips & Best Practices
-
Ensure you understand the distinct networking standards behind the units
-
Use protocol translation hardware or software when interconnecting different network types
-
Consider network conditions as actual throughput may vary from nominal rates
-
Leverage example conversions to verify your calculations
-
Use this tool for approximate planning rather than exact network performance guarantees
Limitations
-
Assumes nominal data rates without factoring in overhead or network coding effects
-
Virtual Tributary 1 and Ethernet are defined by separate standards and not directly interchangeable
-
Conversion does not account for protocol translation requirements or line conditions
Frequently Asked Questions
-
What is Virtual Tributary 1 (signal) used for?
-
It is used to carry lower-rate digital signals over higher-rate SONET/SDH transport links and allows independent grooming and switching within the SONET/SDH hierarchy.
-
What does Gigabit Ethernet represent?
-
Gigabit Ethernet is a set of IEEE 802.3 standards offering data transfer speeds of 1 gigabit per second, typically used in LANs over copper or fiber optic cables.
-
Is the conversion between Virtual Tributary 1 and Ethernet exact?
-
No, the conversion reflects nominal data rates and does not consider protocol overhead or the need for translation hardware, so actual values may differ.
Key Terminology
-
Virtual Tributary 1 (signal)
-
