Bashinformsvyaz JSC, one of the largest service providers in the Urals region and in Russia at large, has deployed the Cisco ONS 15454 Multiservice Transport Platform (MSTP) and Cisco ASR 9000 Series Aggregation Services Routers in key traffic nodes.
As a result, new coherent transponders were installed on DWDM-network multiplexors, ensuring data transmission at the rate of 100 gigabits per second per wavelength. Cisco said this type of transponder features a 100 Gigabit Ethernet client interface for user equipment; it is capable of transmitting data at a distance up to 4,000 km without intermediate Optical-to-Electronic-to-Optical regeneration. Along with the above, Cisco ASR 9000 routers were upgraded with line cards featuring 100 Gigabit Ethernet interfaces; these were connected to 100 Gbps DWDM transponders. This allowed building a high-speed trunk line scalable to 4 Tbps, connecting major cities of the Republic of Bashkortostan. Additionally, traffic grooming and optimization have been performed to enable more efficient utilization of the existing infrastructure; due to deep integration of IP and optical levels, reliability and survivability of the company’s backbone network were dramatically increased.
“Upgrade of the backbone network segment to 100 Gbps helps ensure a huge margin of safety, and efficient and scalable data transport infrastructure required to maintain further network growth and telecom services development within this area. It is very important to notice that implementation of 100 Gbps channels did not require any alterations of the existing DWDM network built some years ago for 10 Gbps speed capacity; our engineer staff was directly involved in those works. This allowed minimizing the deadlines and costs, completing works without interfering with existing services, as well as enriching ourselves with this precious experience of such a large-scale project,” stated Rustam Yanyshev, first deputy general director, CTO, Bashinformsvyaz.
