12 12 © 2010 MAINS Consortium MAINS 2 nd EC Technical Review, Brussels, March 29 th 2012 The MAINS-TP protocol: ACK reduction

13 13 © 2010 MAINS Consortium MAINS 2 nd EC Technical Review, Brussels, March 29 th 2012 Nomadic Virtual PC Application

14 14 © 2010 MAINS Consortium MAINS 2 nd EC Technical Review, Brussels, March 29 th 2012 MAINS GMPLS and PCE implementation activities  Three planned deliverables in T3.4: – D3.2 [M19]: Implementation of service-network interface Deployment of the MNSI Gateway prototype – D3.4 [M24]: Implementation of control plane extensions Deployment of the MAINS GMPLS controllers prototypes (MAINS LER, MAINS LSRs) – D3.5 [M26]: Implementation of the centralized MAINS PCE Deployment of the MAINS PCE centralized server prototype D3.2 D3.5 D3.4

15 15 © 2010 MAINS Consortium MAINS 2 nd EC Technical Review, Brussels, March 29 th 2012 [D3.2 insight] MNSI GW prototype  One VBOX Virtual Machine released: – NXW-GMPLS object code + MAINS UNI client dependencies (base libs): Client Call Controller (CCC) Signalling Controller and G.RSVP-TE protocol Link Resource Manager (LRM) Transport Network Resource Controller (TNRC) – A short guide for installation and operation tips – A set of testing scripts to carry out some early functional tests on the released components  Functional tests scoped to the MAINS UNI signalling initiation: – peering GMPLS edge controllers (UNI-N) (D3.4) – Only IETF call setup procedure tested (i.e. delivery of G.RSVP-TE Notify messages)

16 16 © 2010 MAINS Consortium MAINS 2 nd EC Technical Review, Brussels, March 29 th 2012 [D3.2 insight] MNSI Gateway high-level functional split MNSI Gateway MAINS UNI-CMAINS Network Service Controller MNSI Agent (provider) ServerClient MAINS UNI MNSI Client Call Controller (a/z) Signalling Resource Ctrl Link Resource Manager Transport Network Resource Controller Signalling Controller RSVP-TE

17 17 © 2010 MAINS Consortium MAINS 2 nd EC Technical Review, Brussels, March 29 th 2012 [D3.4 insight] MAINS GMPLS prototype  Three VBOX Virtual Machines released: – MAINS GMPLS UNI-Client controller – MAINS GMPLS Label Edge Router (LER) controller – MAINS GMPLS Label Switch Router (LSR) controller  Each VM contains NXW-GMPLS stack binaries and libraries – gmpls-ccc, gmpls-ncc, gmpls-rc, gmpls-grsvpte, gmpls-lrm, gmpls-scngw, gmpls-tnrc, – gmpls-manager – startup/shutdown ctrl and automatic handling of software modules with inter-dependencies – gmpls-sh (gsh) interactive CLI – single configuration entry point for the whole GMPLS stack  Early functional tests performed on the MAINS GMPLS controllers – sub-wavelength LSP signalling with transport plane emulation  End-to-end sub-wavelength signalling tests in WP4 during Y3 – “horizontal” integration with application layer (i.e. Virtual PC) – “vertical” integration with transport plane (OPST and TSON)

18 18 © 2010 MAINS Consortium MAINS 2 nd EC Technical Review, Brussels, March 29 th 2012 [D3.4 insight] MAINS GMPLS software modules  Choice to focus on key aspects for the prototype implementation OSPF-TE not a key feature to validate/demonstrate the MAINS concepts LRM from each GMPLS controller can directly push towards the MAINS-PCE its local resource information and update them when needed  MAINS concepts and results not affected by OSPF-TE bypass OSPF-TE used as just a raw TE flooder up to the centralized MAINS-PCE

19 19 © 2010 MAINS Consortium MAINS 2 nd EC Technical Review, Brussels, March 29 th 2012 [D3.4 insight] CP/DP interworking: XML interfaces  Final XML#1 and XML#2 operates very differently in terms of control functions – too many native differences between OPST and TSON – unique transformation function between XML#1/XML#2 and XML#3 became unfeasible  Prototype implementation – Two different “XML clients” developed in the GMPLS CP (TNRC Specific Part) TNRC SP for OPST ring (XML#1) TNRC SP for TSON controller (XML#2) – XML#1 and XML#2 called directly from the TNRC Abstract Part TNRC AP maintains the generalized DP model exported to GMPLS protocols (XML#3 like semantic)
