Multiplicity of LP in CSEP Update type of UpdateConnecivityService VLAN tag and so on

Issue – P1 Context B Context A Context C Super Controller Domain Controller 1 Domain Controller 2 NEP ETH Node 1 ODU Node 1 ETH Node 2 ODU Node 2 Link Legend SIP 1 SIP 4 CSEP1 CSEP4 Connectivity Service 1 Create a ETH Connectivity Service with auto-creating server layers connections (ODU, OTSi).

Issue – P2 SC compute the multi- domain multi-layer path. Context C Super Controller Domain Controller 1 Domain Controller 2 ODU Node 1 ETH Node 2 ODU Node 2 ETH Node 1 Context A Context B 1 4 2 3 5 6 Single Domain Connectivity Service 1 Single Domain Connectivity Service 2 NEP Link Legend CSEP SIP Connection SC compute the multi- domain multi-layer path. Request DC to create single- domain Connectivity Service.

Context C Super Controller Domain Controller 1 Domain Controller 2 ODU Node 1 ETH Node 2 ODU Node 2 ETH Node 1 Context A Context B 1 4 2 3 5 6 Single Domain Connectivity Service 1 Single Domain Connectivity Service 2 NEP Link Legend CSEP SIP Connection Issue – P3 If the MappingType of two domains are different, the multi- domain service fail. If CSEP has only one LP instance, CSEP1 and CSEP4 can only be configured with ETH spec, which means can not reach the MappingType in ODU Layer. Ethernet Ethernet ODUflex (GFP-F) ODU2 (GMP) ODU4 ODU4

Solution Make corresponding packages of Spec model (ETH, ODU, OTSi) specify the CSEP. Make CSEP with multiple Layer Protocol instances. Proposed to add this use case to FRD v2.0.

Multiplicity of LP in CSEP Update type of UpdateConnecivityService VLAN tag and so on

UpdateType of UpdateConnecivityService Instead of controller judging the update type as per complex input information, Adding updateType as input will do help to the efficiency of interaction. uses

Multiplicity of LP in CSEP Update type of UpdateConnecivityService VLAN tag access action, ID and type

EVPL Service set up ETH untagged frame C-TAG S-TAG ETH PHY EVPL Connectivity Service 2, VID=100 Context A Context B ETH untagged frame 1 2 4 C-TAG ETH Node 1 ETH Node 2 1 4 Single Domain Connectivity Service 2 S-TAG Legend ETH Node 3 EVPL Connectivity Service 1, VID=200 NEP Link 5 5 SIP ETH PHY CSEP Connection Need to configure the action upon VLAN Tag in CSEP, and show VLAN resource in SIP. CEP

ETH Spec Model – Configure on VLAN tag uses uses Proposed to merge the vlanType and portVid into vlanLabel and add accessAction attribute.

ETH Spec Model – VLAN resource uses The VLAN ID list supports single or batch discrete values, with values ranging from 1 to 4094. ',' or '-' as separators, such as: 1, 3, 5-7
