NEW YORK, NY and LONDON and HONG KONG, Oct. 28, 2009 (Marketwire) --

NEW YORK, NY and LONDON and HONG KONG -- (Marketwire) -- 10/28/09 -- Arbinet Corporation (NASDAQ: ARBX), a leading global provider of innovative voice and IP solutions for buying and selling telecommunications capacity, today announces the release of OptimizedIP(SM) V2, an intelligent Layer 2 IP route optimization service that provides enhanced Internet multi-homing. Through its patented software technology, OptimizedIP V2 offers buyers connectivity to multiple Tier-1 Internet service providers (ISP) via a single connection. The service provides buyers with a single routing table of aggregated Internet backbones. Without adding any additional network hops, the solution optimizes network performance by selecting the best route from among multiple providers, solving performance issues associated with traditional BGP and best effort public Internet routing. The service optimizes Internet data delivery to meet the high quality standards required by performance critical applications such as VoIP, gaming and live video.

Increased demand for high quality Internet access continues to grow as more critical applications rely on Internet Protocol (IP) technology. Traditional BGP provides routing based on the shortest AS path and ignores congestion and key quality metrics such as latency, packet loss and jitter. OptimizedIP V2 addresses these issues by utilizing sophisticated algorithmic configurations to route traffic over the Internet. The service works by determining test IP addresses for networks from the global BGP routing tables and uses Internet Control Message Protocol (ICMP) to ping packets to these test addresses. The results are then analyzed by the OptimizedIP system as often as every 15 minutes. Routing is prioritized based on lowest packet loss, round trip delay and jitter. This process occurs for each individual query ensuring that no matter where the packets need to go, they will get to the destination on the optimal and most efficient path. With only one connection, one routing table and no additional ASN hops, OptimizedIP provides streamlined and optimized Internet service with simultaneous access to multiple suppliers.

"Although IP transit is largely commoditized, our service and test results prove that not all networks are designed equally, and not all networks provide optimal paths for reliably delivering sensitive data," commented Sue Su, Vice President of Arbinet Data Services. "Even the best ISP cannot control the entire path to the end host because it depends on its peering and customer networks.
