Title: Somsubhra Sikdar: Network Connectivity and Flow-Control Innovations.

Introduction

Somsubhra Sikdar is an inventor based in San Jose, California. His patent work includes innovations in network connectivity and data-flow control, with 17 patents attributed to him.

Latest Patents

“Method and Apparatus for Providing Virtual Point-to-Point Connections in a Network” describes a way to establish transparent point-to-point connectivity between interfaces on ingress and egress nodes. The method circulates the egress node’s address and a label value through the network. Each node determines the next hop toward the egress node, allowing data carrying the label to be forwarded along the appropriate path. The labels may include VLAN identifiers or Multiprotocol Label Switching (MPLS) labels.

“Point-to-Point Protocol Flow Control Extension” presents methods for negotiating and managing flow control over Point-to-Point Protocol (PPP) data links. One approach carries IEEE 802.3x MAC control-frame payloads over PPP and passes them to a MAC for flow control. Another allows flow-control commands to be applied to different service classes, enabling per-class control of PPP traffic.

Career Highlights

Sikdar’s listed company affiliations include Force10 Networks, Inc. and Gigafin Networks, Inc. The patent descriptions reflect work on practical networking challenges, including forwarding traffic across a network and managing data flow over PPP links.

Collaborations

His listed coworkers include Kevin J. Rowett and Komal Rathi, reflecting professional connections within the networking and technology field.

Conclusion

Somsubhra Sikdar’s patent portfolio highlights contributions to network connectivity and protocol-level flow control, addressing how data is routed and managed across communication systems.
