The NE5000E was introduced in 2004 and has been upgraded increme

7、ntally over the last 6 years.Huawei claims that they have sold over 1000 NE5000Es to many large network providers in many countries.The NE5000E is composed of the same general parts that all core router are made from; a system processor, switch fabric and line cards. Huawei uses different acronyms t

8、hen Cisco for their hardware. The system processor is called the MPU, the switch fabric is called the SFU and the line card is called the LPU.There are multiple line card versions available for the NE5000E from the first generation LPU-A to the current LPU-F. For doing certain features such as Netfl

9、ow, MPLS VPN and certain types of tunneling the NE5000E uses a service card called the SPU. The line cards utilize TCAMs for forwarding, ACLs, ARP Tables and other features. The NE5000E can be connected to other NE5000Es directly or through a switch fabric chassis to create a multi-chassis system or

10、 “Cluster” as Huawei calls it. Huawei currently claims that their largest cluster, a 4+2 cluster system is in production in China. Huawei does not support fabric Multicast replication on the NE5000E. The source line card does the first two multicast replications and the other line cards handling the

11、 other replications. Due to the fabric usage of Multicast, Unicast traffic can be dropped by the system if there are too many Multicaat replications of any one stream. The Operating System used on the NE5000E is VRP. VRP is a monolithic operating system based on VxWorks. VRP supports limited softwar

12、e patching and claims support process restart.NE5000E TimelineIn 2002 Huawei introduced the NE5000 TSR, a rebadged router from another vendor. The system supported up to 10G per slot and promised performance equal to that of Junipers M120 and Cisco Systems GSR. This router was replaced in 2004 with

13、a Huawei developed system, the NE5000E.The NE5000E is based on the same chassis as the NE80E. The main difference between the two systems is the fabric. The fabric in the NE5000E is 40G while the NE80E was 10G in 2004. Currently both the NE80E and NE5000E have 40G fabrics.The NE5000E was designed in

14、-house at Huawei to compete with the Cisco CRS-1 and the Juniper T-Series. The first release of the NE5000E had a 40G fabric but used the 10G LPU-A line cards from the NE80E. The LPU-A is a 10G capable line card that utilizes the Cisco designed Intel IXP2800 NPU. The first NE5000E specific line card

15、 was the LPU-C. The LPU-C was claimed by Huawei to support up to 20Gb/s at wire-rate but had limited memory and performance. The first claimed 40G capable line card was the LPU-E. The LPU-E has claimed performance of over 60Mpps and 1M IPv4 FIB entries. The current incarnation of the NE5000E has a 4

16、0G Fabric, 8kW power supplies and 40G line cards. The NE5000E is also capable of “Clustering” i.e. Multi-Chassis. With the addition of SFEA (Switch Fabric Extended) fabric cards, the system can connect back-to-back with another NE5000E or to multiple NE5000Es through switch fabric chassis. Most of t

17、he forwarding chips are made by a Huawei sub-company called HiSilicon. The HiSilicon SD588 is a 10G chip and is used on many of the line cards such as the LPUB, LPUC, LPUF. The HiSilicon SD588NFC looks to be a 20G chip and is used in the LPUE.NE Series Release Dates and Backwards Compatibility Pre 2

21、laims that the NE5000E core router has been deployed worldwide. They also claim that by the end of December 30, 2009, more than 1000 routers have been installed and more than 40 NE5000E clusters installed in over 15 backbone/metro core networks.The following is from a press release by Huawei:“In Chi

22、na, China Telecom, China Netcom, China Mobile, China Unicom have used the NE5000E routers in a large scale. Outside of China, the NE5000E routers have been used in a large scale in operators networks of T-mobile in Holland, FT/Orange in Belgium and Portugal, Singtel in Singapore, Globe in Philippine

23、s, Etisalat in Saudi Arabia, TATA in India, America Movil in Ecuador, VIVO in Brazil, Central Telecom in Russian, SuperOnline in Turkey.” Note: The Press release states that NE5000E routers “have been used” outside of china, it does not specifically state that they are currently in use, or are deplo

25、 (Ethernet/POS) and connects to the Switch Fabric Unit (SFU).The Switch Fabric Unit (SFU) connects the Line Processing Units (LPU) together allowing packets to be sent from card to card across the fabric. The Main Processing Unit (MPU) is akin to the Route Processor of the Cisco 12000 Series Router.

26、 The MPU runs the control and management planes of the ChassisFigure 2 - NE5000E Internal ConnectionsNE5000E Physical OverviewNE5000E Chassis The NE5000E has the same physical footprint as the NE80E and the CX600-16. Dimensions of the NE5000E are 442 mm x 669 mm x 1600 mm (width x depth x height). I

27、t weighs about 551 lbs fully loaded. Max power draw is stated at about 6800 watts.Figure 3 NE5000E Chassis and Line Card Numbering Diagram (1) LCD Display (Fans install behind), (2) Cable Management, (3) LPU, (4) Mounting Hardware, (5) Air Intake (Air flows in the front bottom and out the back top)

28、, (6) Power Supplies, (7) HandlesThe NE5000E supports 16 LPUs (Line Processing Unit) in Slots 1-16, 4 SFUs (Switch Fabric Unit) in Slots 19-22, 2 MPUs (Main Processing Unit) in Slots 17-18, redundant fan trays and power suppliesMPU (Master Processing Unit) The Main Processing Unit (MPU) consists of

29、the main control unit, system clock unit, synchronous switching clock unit and system maintenance unit. The MPU controls and manages the system. As the system clock source and the management and maintenance unit, the MPU provides the functions of the control plane, switching plane, and maintenance p

30、lane. The MPU runs the VRP (Versatile Routing Platform) software and is responsible for all of the tasks of a standard route processor. There are two versions of the MPU currently, MPU-A which is used in stand-alone systems and the MPU-B which is required for Clustered systems. The MPU utilizes a Po

31、werPC processor and comes with 2GB of ram and a 512MB CF card.Figure 4 NE5000E MPUSFU (Switch Fabric Unit) There are 4 switch fabric cards in the NE5000E. The fabric runs in a 3+1 redundant configuration (N+1). Each fabric card has 64 3.125G SerDes connections giving them 200G each. The SerDes conne

32、ctions are shared 16 per slot across 16 slots. After encoding there is about 160G usable. SFUC The Switch Fabric Unit rev C (SFUC) is the standard 40G stand-alone fabric for the NE5000E. It is a crossbar-based fabric designed by Dune Networks. This fabric does not do multicast replication.SFEA The Switch Fabric Extend
