L2-L3 SWITCHING & ROUTING

OVERVIEW

Network and Telecom Infrastructure landscape is evolving continuously. Traditional technologies – Time Division Multiplexing, Circuit Switching, Asynchronous Transfer Mode (ATM), Frame Relay (FR), etc., are legacy and not completely relevant today. Throughput, latency, high availability, interoperability and total cost of ownership (TCO) are some of the key factors that drive the choice of future networking technologies. Programmability, automation and scalability along with intelligence are key qualities of networks to capture new market opportunities for incumbent as well as new players. Agility, rapid time-to-market, virtualization and software driven networking are the key differentiators among successful businesses.
IP – Internet Protocol and Carrier Ethernet based networking solutions have evolved to meet the highest standards in LAN / Metro access and aggregation networks. Network Function Virtualization (NFV) and Software Defined Networking (SDN) are the key emerging technologies that bring agility and enable enterprise, datacenter and communication service providers including applications, broadband and Content Delivery and OTT players to offer faster service roll outs and build innovative business models, enable faster time-to-market to be relevant and competitive.

ALTEN Calsoft Labs offers product engineering services to network equipment manufacturers (NEMs) that are helping carriers make the transition from legacy service-specific, multi-network architecture to multi-service converged IP network. Our expertise cuts across L2/L3 switching/routing protocols, IP/MPLS, MPLS-VPN, Traffic Engineering (TE-FRR), Deep Packet Inspections (DPI) & Policy Enforcement, Ethernet OAM (IEEE 802.3ah, IEEE 802.1ag, ITUT Y.1731 standards), EMS/NMS & OSS/BSS, OpenFlow, SDN controller, Virtual Network Function (VNF) and much more! We have rich experience in building multi-vendor products (over 300 products and >1000 software releases during last 20+ years) and solutions for customers ranging from start-up firms up to tier-1 service providers, ISVs – Independent Service Vendors and OTT players.
Our product engineering services address the needs of NEMs and ISVs across the product lifecycle from new product development to product testing, enhancements and maintenance. Since 1992, ALTEN Calsoft Labs has been engaged in design, development and sustenance engineering for industry leading data communication products for access, enterprise, metro and core networks.

Optical Transport

Packet-Optical Transport networks support a combination of technologies that include advanced Ethernet (Layer 2) services running over Connection-oriented Ethernet or G.709 OTN (Layer 1), riding on a DWDM/ROADM (Layer 0) fabric. ALTEN Calsoft Labs works with leading SDN Controller and Optical Network Equipment vendors to simplify service provisioning and multi-vendor multi-layer network management across metro and core optical transport networks.

Since 2011, ALTEN Calsoft Labs has been engaged in development of SDN Applications and Element Adapters [NETCONF, SNMP, CLI, TL1, CORBA, …] to enable dynamic control of services across multi-vendor multi-layered P-OTS networks.

Some of our key areas of expertise are as follows

  • Auto discovery of network elements and multi-vendor network inventory reporting
  • Centralized Alarm Monitoring and Connectivity Fault Management (802.1ag, Y.1731)
  • End-to-End Service Provisioning
  • Data Center Switching
  • WLAN Management
  • SONET/SDH
  • Performance monitoring, KPI reporting and SLA assurance
