Slice Differentiator (SD)
24-Bit Slice Differentiator
Optional 24-bit hexadecimal field distinguishing multiple slices of the same Slice/Service Type (SST).
Technical Explanation
While multiple enterprise clients may all utilize URLLC (SST=2), each client requires an isolated slice with custom policies and security perimeters. The 24-bit SD (providing over 16 million unique IDs) separates distinct enterprise tenants within the same SST category.
Key Functions
- 24-bit hex value providing fine-grained multi-tenant slice differentiation
- Allows over 16 million distinct private slices per standardized SST
- Enables dedicated enterprise SLAs for different commercial corporate clients
