Amsterdam-based Linxtelecom Deploys ADVA Amsterdam-based Linxtelecom has selected ADVA Optical Networking's FSP 3000 to enhance speed connectivity across parts of its network. The network delivers transport between data centers separated by international borders and provides local peering with Internet exchanges. Initial deployments have been done in Russia and the Baltic countries.
Linxtelecom provides a range of services including international private lines (IPL), wavelength services, IP transit, MPLS-VPNs and Virtual-Point of Presence (VPoP) solutions via a network spanning Western Europe, the Nordic countries, Russia, the Baltic States, Poland, Ukraine and Georgia. Linxtelecom also offers co-location and dedicated server services from its data centers in Tallinn, Estonia and Moscow, with another state-of-the art data center to be launched soon in St. Petersburg.
As data traffic levels in the region continue to rise, providing PoP-to-PoP or end-to-end services via dark fiber has became more difficult since suitable transmission channels are sparse. Linxtelecom decided to deploy ADVA's FSP 3000 based on the platform's ability to flexibly support multiple services with a limited number of cards, its multi-haul capability, carrier-class reliability and ease-of-use.http://www.advaoptical.com

Arista, Fulcrum and Ixia Test 10-Gigabit Ethernet for Cloud Networking Arista Networks, Fulcrum Microsystems and Ixia announced the results of collaborative performance and scalability testing of 10-Gigabit Ethernet in a cloud computing environment. The tests measured the performance of the Arista 7148SX 48-port 10GE SFP+ switch, which features Fulcrum's FocalPoint FM4224 switch silicon. The tests used full line-rate, large-scale traffic running fully meshed and yielded results that validated the switch's ability to provide the low-latency and throughput performance for lossless data center Ethernet transmission.
According to the companies, the test results showed "extraordinarily low latency" in the Arista switch -- as low as 600 nanoseconds (min) between any two ports -- and lossless performance for all frame sizes using IETF RFC 2544 and 2889 throughput test methodologies. This performance means scale-out environments can now get true non-blocking performance using the Arista 7148SX switches, as shown by the absence of packet drops in the RFC 2889 full-mesh test results.http://www.aristanetworks.com

Xelerated Supports Precision Time Protocol and Synchronous Ethernet in Silicon Xelerated introduced a Precision Time Solution that enables its network processors and programmable Ethernet switching silicon to preserve synchronization in packet-based mobile backhaul links.
Significantly, Xelerated's Precision Time Solution provides hardware and software support for both Precision Time Protocol (IEEE 1588 v1 and v2/2008) and Synchronous Ethernet (ITU G.8262). For maximum flexibility, the solution supports any type of synchronization service on any port. Special attention has been put to highly accurate time stamping, time and frequency monitoring, as well as optimized performance supporting one-step operations for Precision Time Protocol.
Xelerated said its design allow mobile backhaul providers to evolve their services as the LTE technology framework is updated with new standards for quality of service, synchronization and service interworking. In addition, programmability enables system vendors to offer a common portfolio meeting the stringent PTN requirements as outlined by China Mobile while paving the way for LTE.
"Next-generation mobile backhaul must leverage a unified fiber access design to meet the price points and dense service requirements in LTE. A unified approach with superior synchronous options can make this solution happen now," said Thomas Eklund, vice president of marketing and business development for Xelerated. "We have put extensive resources into our new Precision Time Solution, which enables service providers to securely migrate to Carrier Ethernet and stop investing in costly legacy equipment with limited lifetimes."http://www.xelerated.com
