The ATWebHost network consists of two separate networks: a public Internet network and a private internal network. This “network within a network” design is comprised of two logically separate and redundant network architectures.
The public Internet network connects client servers to the Internet at 10 / 100 / 1000Mbps port speeds. Each client is isolated to their own private VLAN to maximize security. This network is continuously monitored for performance and reliability.
The private internal network is not reachable from the public Internet. It also separates client servers into their own private VLAN security purposes, and also allows us to provide many services not found at other providers. The private network allows your servers to securely communicate at speeds up to 1000Mbps without incurring any bandwidth charges. This eliminates additional switch charges, cross connect fees, and having to move servers from rack to rack as you add servers.
The private network also connects all servers to internal services offered by ATWebHost: off-server backup, Network Attached Storage, update servers, local DNS resolvers, service monitoring, IPMI metrics, and software/OS performance metrics all without using any of the public bandwidth allowance.
We took great care in researching and selecting only the highest quality Tier 1 bandwidth providers for our network to ensure we provide low latency and high availability to all locations both domestically and abroad.
Level(3) was recently named as the #1 IP transit provider in the world by Renesys Corp, an independent research firm. Level(3) operates one of the world’s largest, newest and most advanced Tier 1 telecommunications networks. The network spans 23,000 intercity route miles and serves the world’s 10 largest phone companies, 10 largest Internet service providers, and 6 largest cable providers. Level(3) is currently ranked #1 AS in the world by CAIDA.
Hardware
Our robust and scalable network utilizes only routing and switching products from industry-leaders Cisco Systems and Juniper Networks. We use Juniper M-series routers in our border routing layer and Juniper EX4200 and Cisco 3750 series switch stacks in our core switching and aggregation layer. This setup is fully meshed with redundant internal and external fiber connections for maximum reliability. At the client access level we use Cisco access switches for both our public and private networks. These switches are connected in a bonded, redundant fashion to our core layer to not only enhance reliability but to reduce the risk of congestion and provide maximum throughput.
