The customer is a world-famous telecom equipment manufacturer. One of the core products in
the client’s portfolio is a generic hardware and infrastructure server platform designed to host one or more
telecom applications and provide reliable and scalable services.
The customer tasked MERA to consolidate the R&D of switching and routing components by
reducing the number of suppliers and production sites. By that time, MERA professionals had already been providing
the customer with the development and maintenance services and proven themselves to be reliable partners. With our
successful collaboration and the progress achieved in mind, the customer assigned MERA as an end-to-end partner
for all the R&D activities in regard to switching and routing components. At that moment, the products
transferred to MERA suffered from a number of long-lasting software-related problems, which undermined their
quality. MERA was to perform knowledge transfer at short notice and promptly show a significant progress in terms
of both product quality and new functionality.
In as little as two months, MERA concluded the knowledge transfer and took over full
responsibility for the product design. Right after this, we launched an ambitious improvement program aimed at:
All of the above was done in parallel with the development of new features requested by the
customer. As part of this project, we have also implemented a VLAN translation feature that enables the product
users to significantly reduce the time and complexity of the initial system configuration and its further
- architecture analysis and deployment of systemized technical improvements such as a single-thread SNMP
- introduction of static analysis tools as part of the nightly build procedures;
- improvement of the test coverage and automated test cases stability, including the implementation of a
Continuous Integration framework.
After six months of full product responsibility, the MERA team has accomplished the
- reduction of the total number of defects from 50+ to a single-digit backlog;
- stabilization of the test and CI environment: the number of successful CI runs has increased from <50% to
- 0 days of delivery delay.
Major features implemented:
- Security updates for switching and routing components (ANSSI)
- VRRP tracking BFD, VRRP
- Ability to pre-configure port density using DHCP
- NET-SNMP single-thread handling
- IPv4/32 & IPv6/128 route handling
- Next-hops in a ECMP group
- BGP support in line with RFC 4271, RFC 4760 and RFC 3392
- Excessive number of LSAs in OSPF DB (OSPF DB limits)
