Bashinformsvyaz upgrades backbone to 100G with Cisco

Cisco Systems Inc. (NASDAQ: CSCO) and Bashinformsvyaz JSC, one of the largest service providers in the Urals region, have completed another phase in the upgrade of the service provider’s multiservice network operating in the territory of the Republic of Bashkortostan.

Bashinformsvyaz added new capabilities to its existing DWDM network, which is based on Cisco’s ONS 15454 multiservice transport platform (MSTP) and IP/MPLS network core routers in key traffic nodes as well as Cisco ASR 9000 series aggregation services routers.

New coherent transponders were installed on the DWDM network equipment, ensuring data transmission at the rate of 100 Gbps per wavelength. This type of transponder features a 100 Gigabit Ethernet (100GbE) client interface for user equipment; it is capable of transmitting data at a distance up to 4000 km without intermediate optical-to-electronic-to-optical regeneration.

Along with the above, Cisco ASR 9000 routers were upgraded with line cards featuring 100GbE interfaces; these were connected to the 100-Gbps DWDM transponders. This made it possible to build a high-speed trunk line scalable to 4 Tbps, connecting major cities of the Republic of Bashkortostan. Additionally, traffic grooming and optimization can be performed to enable more efficient use 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, Cisco asserts.

"At present, the DWDM network of Bashinformsvyaz is one of the most sophisticated networks in the territory of Russia; it is capable of transferring virtually any data volume between any regions of the Republic of Bashkortostan," asserted Yury Kazantsev, deputy director, service provider sales, Cisco Russia.

"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," Rustam Yanyshev, first deputy general director, CTO, Bashinformsvyaz. "It is very important to notice that implementation of the 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."
