Role : Team Member

Description:-

NCSK4000 is a new platform from CISCO.

NCSK4000 Chassis is high-end core L3 Route processor of CISCO SCAPA family by using CLI to configure and switching data path between multiple core router processors and it having capacity of 3.2 Tbs. This has 22 slots, this supports 16 slots for various line cards, 4 Fabric-cards and 2Route processors

This Line cards enables for OTN switching functionality in Scapa system by providing. G.709/G.798/G.783/GSUP43 functionality for various clients like OTN, Ethernet and SONET

It's core switch and it's will map various protocols into OTN rates by using framer devices. It will packetize and forwarded by using broad com devices and with support of fabric-cards.

My responsibilities in this project include:

Written Design docs for all data plane (data path) implementation.

Board bring up

Device driver development

Third party software (SDK) implementation.

HA implementation for DIGI and CPAK card.

APS (1+1) switching requirements.

N-S integration with DWDM

LINE CARDS:-

LINE CARD 1:- CPAK 2X100 ( 100GE and OTU4 )

This Line card enables for OTN switching functionality in Scapa system by providing G.709/G.798/G.783/GSUP43 functionality for various clients like OTN and Ethernet. There are two DIGI120 framer devices on line card that provide G.709/G.798/G.783/GSUP43 functionality. This LC has 2 100GbE ports. Each port can have one CPAK optical module. The CPAK can support 100GE or OTU4 (100 Gbps). The maximum total raw bandwidth handling capability of this card is 200Gbps on the line side. These ports are connected to 2 DIGI120G devices.

The CPAK daughter card will contain Lepton FPGA implemented in Xilinx Spartan-6 LXT FPGA; Line card can communicate with Lepton FPGA through various interfaces BAO I2C, BAO master I2C, CCC I2C, and PCIe. PCIe interface is used to configure Lepton FPGA. And the Gear Box-2 PHY devices are configured with I2C to MDIO bridge logic residing inside Lepton FPGA. Lepton FPGA will have slave I2C for all the three I2C bus from MB.

DIGI device is connected to AMBA device which provides fabric interface.

LINE CARD 2x100 has 2(2 CPAK plug gables (100GE)) port front panel of chassis. This supports OTU-4 and 100GE.

Written device driver for following chipset to configure and mapping the 100GE and OTU4 data paths, PMC5440, GN2411, BCM86572 and BCM8652

My responsibilities in this project include:

1. Bring up and Device driver development

2. Configuring the kernel to final image

LINE-CARD 2:- DIGI 20X10 ( 10GE,OTU2 and OC-192 )

This Line card enables for OTN switching functionality in Scapa system by providing G.709/G.798/G.783/GSUP43 functionality for various clients like OTN, Ethernet and SONET. There are two DIGI120 (PMC5440) framer devices and GN2411 on line card that provide G.709/G.798/G.783/GSUP43 functionality. This LC has 20 10GbE or OC192 ports. Each port can have one pluggable SFP+ optical module. The SFP+ can support either 10Gigabit Ethernet (10Gbps) or OC192 (10Gbps) or OTU2 (10Gbps). The maximum total raw bandwidth handling capability of this card is 200Gbps on the line side. These ports are connected to 2 DIGI120G devices.
