PTN-TMPLS进展.ppt

TMPLS/PTN标准与产品进展概况 上海贝尔阿尔卡特股份有限公司 * 从T-MPLS到MPLS-TP ITU-T 首先意识到分组传送的需要，即一个严格面向连接的分组传送技术，侧重于传送目的，支持可与SDH媲美的电信级的OAM和生存性。从2005年五月开始，ITU组织起草了一系列T-MPLS标准，并在市场上获得了成功应用。 2007年IETF也意识到了分组传送的重要性，希望开展这方面的活动。2008年2月ITU-T和IETF组成了联合工作组，协调对分组传送技术的标准化工作。 促进ITU-T和IETF的快速信息交换； 保证两者工作一致协调，消除矛盾和差别。 联合工作组将分组传送定义为“MPLS Transport Profile” (MPLS-TP)，定位于T-MPLS的演进。 T-MPLS仍然有效，并将在ITU-T完善其标准化工作； MPLS-TP认可T-MPLS现有的标准规范，并借鉴了其中大部分内容； 从事T-MPLS标准化工作的专家仍将在MPLS-TP标准化工作中起主导作用。（见下页） 工作组成员 Operators BT Verizon ATT NTT Comcast Vendors Acreo AB Alcatel-Lucent Cisco Ericsson Huawei Juniper Nortel Old Dog Consulting 总结 CMCC PTN BMT overview CMCC is going to investigate emerging transport technologies for NG transmission network via this BMT test, especially on the trends of packetlization. 3 kind of main packet transport technologies are tested: TMPLS: Huawei(OSN3900/1900), ZTE(8905/8902), Fiberhome, UTStarcom, ALU PBT: Huawei(CX600/300), ZTE(8905/8902), Nortel, Fiberhome ZTE uses same equipment for both TMPLS and PBT test VPLS: ALU, Cisco CMCC BMT topology Results summary Test is divided 11 parts totally, including: 1, Supported Services; 2, Service performance; 3, TMPLS forwarding plane (label process); 4, Network protection; 5, QoS; 6, OAM; 7, Timing on Packet; 8, Equipment; 9, Network management; 10, Control plane; 11, Interworking; TSS-5 is used for CES tests within part 1, part 2 and part 7. (about 20 items) TSS-320/TMPLS related test items are about 70 items. ( regarding NMS, OAM 1 test item respectively), which doesn’t include additional 2 items suggested by ALU Hereafter, discussion is based on these 70 test items. Results summary (1) Part 1: Supported Service: Ethernet service and ATM service are tested in this part This part is the lowest scores part within test parts, because we can’t support ELAN/ETree service (6 items) with R3.0 Pre-DR4 software. After R3.0 DR4, we do support ELAN/ETREE. Results summary (2) Part 2: Service performance: (6/10) Corresponding to part1, this part test rel
