IBM India Pvt Ltd, Bangalore

Designation: Staff Software Developer

Duration: Since May 2013 till Nov 2014 (1 year 7 months)

Language: C and Python

Brief Summary: Have worked on Network virtualization technologies, Openflow protocol, SDN Controller, Vxlan tunneling for KVM hyper visor using Linux Bridge and Open Virtual Switch under IBM proprietary DOVE (Distributed Overlay Virtual Ethernet) solution.

Modules worked on:

1. SDN Controller (Open VirtualSwitch) :

Worked on SDN Controller using Openflow 1.3.3 specifications which works with Linux Openvswitch. Openvswitch with tiered approach and Vxlan based VNID provide the tunneling support for Virtual machine. Controller as a KVM host agent on north contacts the policy server (DOVE appliance) for the VNID based policies and install flows for communication for unicast, multicast and broadcast. Where as in south it is responsible for handling the Openvswitch flow installation and mac resolution.

2. Host Agent (Linux Bridge):

Worked on Host Agent which works with Linux Bridge implementation. LB with tiered approach and Vxlan based VNID provide the tunneling support for Virtual machine. Host Agent is responsible for endpoint notification or migration and handles the VM using the libvirt interface and Linux FDB and neigh table entries

BROCADE COMMUNICATION SYSTEMS, Bangalore

Designation: Software Developer

Duration: August 2010 – May 2013 (2 years 9 months)

Language: C

Brief Summary: Two plus years of experience in NSM and HSL modules in the network OS. NSM and HSL provide necessary infrastructure for the L2/L3 protocol clients and behave as the abstraction layer between user space and ASIC driver modules.

Modules worked on:

1.HSL - KAP:

HSL (Hardware Subsystem Layer) kernel resident component serves as an integration layer between the protocol applications and the underlying HW platform. It serves as a hardware abstraction layer and supports tx/rx services for both L2 and L3 applications. It runs in either centralized or distributed fashion. HSL agent which sits on LC can store a sample packet and make decision to send it to protocol modules appropriately.

2.NSM - CDB:

NSM (Network Services Module) is a user space DCE daemon that is responsible for interface management, configuration management and message synchronization between other modules. It stores a repository of interfaces and interacts with the HSL kernel module to receive events and information. Other modules which need data from NSM have to register themselves as clients to NSM. It communicates configs/state changes to its clients.

Designation: Sustaining Engineer

Duration: July 2007 – July 2010 (3 years)

Language: C

Brief Summary: Three years of experience in ONTAP kernel,

Sustenance in WAFL File system, File system inconsistency, blocks reallocation, buffer management and interface between WAFL and RAID domains.

Modules worked on:

1. WAFL Filesystem block reallocation aka segment cleaning: As a WAFL file system ages, disk free space tends to become fragmented, As a result, write performance slows over time. Fragmentation can be fixed by moving data on disk by segment cleaning.

2.WAFL – RAID interface: Lost writes/In-memory corruptions and software defects and RAID hold every blocks context and it is used for consistency checking. RAID error propagation ‘REP’ to the WAFL Filesystem for different types of blocks L0’s and metadata and Pseudo block return for the L0 blocks.
