Transition from IPv4 to IPv6 Abstract: This paper explains and discusses the current transition mechanisms to IPv6 and their applicability to different network scenario. Also discussed is the evolutionary work being done in different IETF working groups to address new realities in the IPv6 deployment. Read more...
Making Agile Work on Offshore Development Abstract: HSC recently participated in the prestigious Project Management Leadership (PML) 2011 event where we presented our experiences in successfully applying Agile methodologies to large projects executed offshore from the customer site.The paper was selected as a runner up in the abovementioned event. Abstract: Other than understanding the organizational and cultural aspects related to application of Agile methods, modification and adaptation of Agile practices to suit the organization’s business context and existing systems and processes is imperative for making Agile work.

A unique project management model for end-end delivery Abstract: In the today’s market scenario of intense competition, the organizations face the challenges of low price and high quality. The traditional model of separate teams for delivery puts additional burden on these factors adding to additional pressure. The key to success is knowledge re-use wherever possible and spreading the roles and responsibilities across the different delivery phases. The intent of the paper is to highlight one such practice for handling these challenges. Read more...
TCP revisited Abstract: TCP is transmission Control Protocol, the Layer4 protocol for communication over both wireline as well as wireless links. It is one of the most widespread of protocols in usage today. All key applications defining the web today, http, email transfer, file transfer, etc. Read more...

Cisco Complaint XOT implementation to enable X.25 overlay over a satellite base IP network backhaul Abstract: The existing implementation used a proprietary backbone protocol to send serial data across the Satellite based IP network which mandates a proprietary node at CO side to terminate TCP connection initiated between the VSAT and the Serial Gateway. HSC enhanced this implementation by augmenting it with the standard XoT implementation(as per Cisco informational RFC 1613) in order to have the flexibility to do away with the Serial Gateway at the CO side and replace it by industry standard devices from vendors like Cisco, IBM.

Implementation of a TR-069 Data Model (DM) Client Framework for a WiMAX CPE Abstract: TheTR069 client Framework implemented on VxWorks provides Event Discard Policy, Session Retry Policy; secured communication with remote servers using SSL 3.0/TLS 1.0 and Basic/digest Authentication. It provides interfaces for CPE applications to interact with ACS server. Read more...
Enhancing IPv4 VSAT to a Dual Mode VSAT (IPv4/IPv6) Abstract: Typically a VSAT has two major interfaces, the LAN side on which it has subtended user networks and the RF Network side. Implementation includes IPv6 Neighbor Discovery and translation algorithms for IPv6-IPv4-IPv6 traffic terminating on the VSAT. This enabled an IPv6 host to access application on VSAT supporting only IPv4. Customer Benefits: Flexibility of subtending IPv4 or IPv6 networks on the LAN side Enable IPv6 interface with minimal changes on the existing software on the VSAT. Read more...
