Explanation
SENC1
SENC1 unit
Designates the encryption unit SENC1-4, SENC1F4, SENC1-8 or SENC1F8 of FOX61x, or its representation in FOXMAN-UN. The unit can be plugged into a FOX61x subrack.
Where certain features or characteristics apply to a specific encryption unit only, the SENC1-4, SENC1F4, SENC1-8 or SENC1F8 is named explicitly.
Core Unit
Designates the core and control unit of type CESM1, CESM1-F, CESM2, CESM2-F or CESM3 of FOX61x.
Where certain features or characteristics apply to a specific core unit only, the CESM1, CESM1-F, CESM2, CESM2-F or CESM3 is named explicitly.
dirac user
The user ‘dirac’ is the manager of the DIRAC key distribution system.
Board
In the SENC1 context a board is a SENC1 physical HW unit. The board is identified by a 10 to 13 digit number.
Example:
SENC1 board serial number: 4910764000
CE
Crypto Engine
In the SENC1 context a CE is a Crypto Engine. A Functional Unit (FU) has two CEs: CE A and CE B.
The Crypto Engine is identified by a 12 to 15 digit number which is composed of the 10 to 13 digits SENC1 board serial number, the Functional Unit number, and the Crypto Engine number.
Examples:
SENC1 board serial number: 4910764000
Functional Unit number: 1 or 2
Crypto Engine number: 1 (for CE A) or 2 (for CE B)
CE ID: 491076400011, or
491076400012, or
491076400021, or
491076400022.
ENP
Ethernet Networking Package of FOXMAN-UN.
ESM
Ethernet Security Manager of FOXMAN-UN.
FU
Functional Unit
In the SENC1 context a FU is a Functional Unit. A SENC1 unit has one (SENC1-4 and SENC1F4) or two (SENC1-8 and SENC1F8) FUs: FU 1, FU 2.
The Functional Unit is identified by an 11 to 14 digit number which is composed of the 10 to 13 digits SENC1 board serial number and the Functional Unit number.
Examples:
SENC1 board serial number: 4910764000
Functional Unit number: 1 or 2
FU ID: 49107640001, or
49107640002.
MK
Master Key
Master Keys are generated and distributed whenever FOXMAN-UN deploys an encrypted tunnel, or on request of the DIRAC operator. Master Keys are generated for a particular Label Switched Path (LSP) and distributed to all MPLS tunnel endpoints terminating this LSP.
NE
Network Element
In the FOX61x context a NE is a subrack equipped with core and service units.
In the SENC1/DIRAC context an FU behaves similar to an NE in certain aspects. Refer to the term “FU”.
