SAVVIS has deployed a new Application Transport Network (ATN) based on the Cisco IP Next-Generation Network architecture. As part of a major network and data center upgrade, SAVVIS has now enhanced its global wide area network (WAN) and integrated it with its hosting area network (HAN) infrastructure resulting in a managed application transport network that further virtualizes and optimizes the delivery of enterprise applications.
The SAVVIS ATN is a Tier 1 MPLS network serving approximately 20 percent of the world’s Internet routes. It features the Cisco CRS-1 Carrier Routing System with Cisco IOS XR Software at the core, along with the Cisco XR 12000 Series Routers incorporating the Cisco Multi-Service Blade (MSB) as multi-service edge platforms. The CRS-1 and XR 12000 routers serve as access and integration points connecting SAVVIS’ network and data centers.
SAVVIS’ WAN enhancements include new core and edge routers that enable MPLS, high-speed metro Ethernet access, and enhanced end-to-end customer controlled QoS, which when combined with SAVVIS’ monitoring and management enables high performance Application Transport Services (ATS) for public and private network enterprise needs.
The companies said enhancements to the HAN augment the WAN upgrade and feature the deployment of the Cisco Application Control Engine (ACE) Blade and Firewall Services Module that is now in production in 13 SAVVIS data centers. This integrated Virtual Services Switch features a 10G network fabric with GigE and 10G customer handoffs significantly improving load balancing, SSL acceleration and security services, as well as enhancing SAVVIS’ ability to provide a much broader range of virtualized utility services.
As part of the WAN and HAN integration, SAVVIS has deployed the Cisco Multi-Service Blade, which facilitates virtual firewalls and is integrated with the Cisco XR 12000 Series Router. This enhances security performance and flexibility for SAVVIS customers as it now enables a second generation of in-the-cloud, virtual firewalls.
