MIGRATION t IPv6 MTNL PLAN & PERSPECTIVE 1
MTNL RESPONSE TO TRAI RECOMMENDATIONS ON IPv6 (JUNE, 2006) (a) (b) (c) (d) (e) IPv6 migratin is a cmplex issue and need jint effrt. Deptt. f Telecm/Deptt. f IT/Gvt. shuld initiate t set up IPv6 test bed. Set up Natinal Internet Registry. Cnduct training and awareness prgramme. Upgrade cst d nt allw ne time up gradatin and life cycle upgrade is the feasible ptin. 2
IP BASED NETWORK/SERVICES INFRASTRUCTURE IN MTNL ISP PPs, Internet access. MPLS, L2/L3 VPNs, Multicast, QS. Bradband access XDSL, Metr Ethernet, 3G. Wireless Netwrk, 3G services, GPRS. NGN (C4) CPEs DSL CPEs, STBs, IP phnes, Sft Clients. OSS/BSS : DNS, DHCP, AAA (RADIUS), NMS, PMS, WSC, Billing & CRM. Services : IPTV, VOIP, VASs. 3
IPv6 MIGRATION CHALLENGES Hw t define IPv6 migratin Timeframe/Radmap. - IPv4 based equipment still being manufactured /supplied. Hw t test / assess the equipment / services fr * Cnfrmance - t IPv6 features & prtcls. * Perfrmance - thrughput, latency, packet lss / resurces required fr IPv6. * Security * Mbility * Interperability Hw t evaluate IPv6 effect in terms f csts invlved / ROI and disruptin etc. 4
IPv6 MIGRATION PLAN IPv6 Prcurement Plan. IPv6 Deplyment strategy. Netwrks/Services cmpnent testing. Netwrk & Service Integratin. - Exceptinal strategy. - Integratin Plan - Security Plan finalizatin. - Actual Implementatin. IPv4 and IPv6 t c exist fr sme time and migratin t happen nly as life cycle upgrade f the prducts 5
IPv6 PROCUREMENT PLAN MTNL had decided (>3 years back) that all hardware, sftware, and Applicatin being prcured, shall be IPv6 cmpliant and accrdingly adhering t it fr all prcurements: Hw t ensure? Requires mandate fr the vendrs. Requires incentive such as tax relief t vendrs t manufacturer IPv6 cmpliant hardware/sftware/ applicatin. 6
IPv6 DEPLOYMENT STRATEGY Architectural Slutins: Native IPv6. Dual Stack. Tunnelling. Prtcl translatin 6PE, 6VPE. MTNL t finalize after assessment/testing f the assessment f available features n Edge & Cre ruters and access NW cmpnents 7
TESTING Testing fr - Cnfrmity t IPv6 technlgy and prtcls. Perfrmance i.e. thrughput, latency, packet lss /prcessing and memry requirement etc. Security, Mbility, QS requirements. Inter-perability. Cmpnents t be tested - Edge ruters and cre ruters Cmpnents f access netwrk and ther NW islands. Applicatin sftware and services. *Test Bed Required. 8
IP ADDRESSING Obtain IPv6 Address Blck/IPv6 suffix frm the centralized (natinal/reginal) Internet Registry. Set up Natinal Internet registry? Develp Addressing Plan and frmulate Address Distributin mechanism t custmers. 9
NETWORK & SERVICES INTEGRATION Analyse varius Netwrk/Systems and services fr IPv6 cmpliance and migratin radmap. IPv6 exceptin strategy identificatin f cmpnents (HW/SW/Services) that will remain IPv4. Integrate prgressively the existing/new IPv6 cmpliant netwrk Island(s) with IPv6 cmpliant, Transprt N/W High level analysis f NWs/services fr IPv6 cmpliance and identificatin f cmpnents that will remain IPv4 is underway - migratin t IPv6 nly as the life cycle upgrade 10
SECURITY PLAN Access IPv6 security requirements & finalize Security Plan. Security requirements. Des the NW supprt IPv6 based slated reference extended ACL. Server cnnectivity e.g - Supprt IP Sec. - Prtcl authenticatin fr OSPF V.3 - IPv6 IP Sec terminal, ruter-t-ruter. - IPv4/IPv6 Encryptin Hardware adapter. - Mbile IP authenticatin. IPv6 Firewall - Des the FW supprt IPv4/ IPv6. - Des NIDS/NIPS supprt IPv4/ IPv6. - Security Applicatin. TEST BED REQUIRED 11
HIGH LEVEL NW/SERVICES ANALYSIS MPLS TRANSPORT (CORE & AGGREGATION PE & P ruters : IPv6 cmpliant (t be verified). Aggregatin/CE : IPv6 cmpliant (t be ruters verified) ems/nms : T be tested fr IPv6 cmpliance & interperability / t be upgraded required 12
ISP NETWORK Gateway Ruter : IPv6 cmpliant (t be verified) Web Server/Caching Server : T be verified/ upgraded. Messaging/ Security/ Firewall/ : Under replacement by IPv6 DNS : cmpliant Hardware/ Sftware as : part f planned upgrade. ISP/LL ruters/ switches : Narrw band RAS : Shall remain IPv4 island ISP NW t evlve t supprt bth IPv4 and IPv6 versins at the same time ( dual stack apprach )
BROADBAND ACCESS (xdsl & Metr Ethernet) BRAS, Tier 1 & Tier 2 switches, MES, ME- CPEs : IPv6 cmpliant (t be verified) DSLAM & DSLAM CPEs : ems & NMS system : Plicy Cntrl (SSSC) : T be verified fr IPv6 cmpliance else shall remain IPv4 island and tunnelling used in access. IPv6 cmpliant (t be verified) T be upgraded t IPv6. 14
WIRELESS BROADBAND (a) Sft Switch (3G) : T be tested fr IPv6 cmpliance else upgraded t IPv6 / retained as IPv4 islands and replaced as life cycle upgrade f their netwrks/systems. TMG/SGW GGSN (GPRS) : T remain as IPv4 islands. GGSN t be replaced as life cycle upgrade (b) CDMA (PDSN) : T remain as IPv4 islands 15
NGN (C.4) Sft-switch and ther cmpnents. : T be tested fr IPv6 cmpliance & upgraded t IPv6 if required. 16
VOICE OVER IP (VOIP) IPv6 Readiness fr SIP Server T be ensured frm Service Partner. OSS DHCP, DNS, NMS : T be ensured frm Service Partner. BSS : Cnvergent Billing t be used after due testing. IP Phne / PC Sft client :? 17
IPTV IPv6 readiness fr Head End. Equipment : Service Partner t ensure. Metr Ethernet, XDSL, access and CPE / STB : T be verified fr IPv6 cmpliance else shall remain IPv4 island and tunnelling used in access. OSS / BSS Cnvergent Billing & CRM t be used after due testing and integratin. 18
AAA fr dial-up & Bradband n IPv6. Mediatin/ Billing/ Prvisining/ CRM/Web Selfcare,. DNS (which understands IPv4 A recrd and IPv6 AAAA recrd) OSS/BSS MIGRATION PLAN : Upgrade t IPv6 cmpliant system. : Migratin t/use f Cnvergent Billing & CRM system test upgrade. : T be Upgraded Legal Interceptin. : T be assessed and upgraded. Plicy Cntrl (SSSC) : T be upgraded. NMS t be tested and evlutin planned t cater fr fllwing : - Netwrk Management evlutin needs t be dne befre IPv6 deplyment strategy. - System / Applicatin / Prtcl t be cnsidered. - In a Dual Stack Netwrk, bth IPv4 & IPv6 envirnment must be managed with best ptimizatin t decrease cst f peratin. 19
SUMMARY Defining Migratin Radmap is a challenge - availability f IPv6 cmpliant equipment is still issue. Supply f IPv6 cmpliant equipment (frm a given date) shuld be mandated. IPv6 Test bed - Deptt. f IT / DOT (TEC) / Gvt. t take up challenges. Setting up f Natinal Internet Registry Gvt / DIT t decide IPv6 address allcatin Gvt. / DOIT t take challenge. IPv6 Awareness & Training Prgrammes need t be cnducted. MTNL shall upgrade Netwrk/system cmpnents nly as life cycle upgrade. 20
