The networking practice builds software for networked appliances. The work in this practice spans the complete software stack from kernel development services to libraries to applications. The broad classification of what the practice does is as below:

Differentiation

It is evident that networking technology is becoming more and more application aware in order to provide the best possible user experience. A direct consequence of this is the fact that decisions deep down in the stack are affected by the understanding of application and user behavior. GS Lab’s networking practice is differentiated by its insight of issues in all layers of the software stack.

Some of the current work in progress

  Layer 7 application firewall appliance for the data center market
  Boot services for a high speed interconnect switch fabric
  Gigabit data recorder
  NIC level throughput enhancement for cloud computing applications
  Mobile IP v6 and network mobility
  Payload capture, inspection, and reporting

Delivery capabilities

The networking practice has delivered a number of complete products and/or features ground up. Here’s a sampling that gives an idea of the type of work delivered.

  Peer-to-peer Internet service built on MIPv6 standards to create secure, simple,      persistent connection between mobile, fixed computers and other network devices
  Communication using secure IPSec tunnel between devices within a VPN group that      works over Firewalls and NATs
  Packet inspections, processing, encapsulation, and policy enforcement
  Support for mobile routers by implementing NEMO (Network Mobility) specifications.      Provide accessibility to nodes behind mobile routers
  Support secure communication through mobile router to mobile nodes guaranteed      using SEND (Secure Neighbor Discovery) implantation
  Directory virtualization for LDAP (Lightweight directory protocol) and AD
     (Active Directory)
  SASL, Kerberos, NTLM based authentications

The networking practice has accumulated specific expertise on booting services for diskless blade servers and also on specific protocols for high performance networks such as Infiniband.

  Developing kernel drivers (RHEL, SuSE), low-level firmware solutions and testing      enterprise grade Infiniband switches, Ethernet and Fibre channel gateways
  Various upper layer protocols of the Infiniband software stack like IPoIB (IP over      Infiniband), SDP (Sockets Direct Protocol), SRP (SCSI RDMA Protocol), MPI (Message      Passing Interface), etc.
  Infiniband open source communities and interoperability working groups
  Boot firmware solutions for the Infiniband Host Channel Adapter (HCA)
  Interfacing with device firmware and BIOS level interactions to provide the OS boot      loader transparent access to remote disks

The networking practice of GS Lab also engages with the customers for the design, development and testing of the network management system. The technologies used are:

  J2EE/Web based NMS UI,
  Swing/AWT/C++ based standalone NMS application, and
  SNMP/HTTP based element management system for embedded devices.
