Network

The SoftLayer network provides more than 2,000Gbps of connectivity across a global footprint of 13 data centers and 16 points of presence (PoPs). We have enabled 20Gbps network connections across our locations that are provided by leading global network providers, and include multiple public peering links to dozens of additional Internet access networks.

Our network is actually three distinct and redundant gigabit network architectures—public, private, and data center-to-data center—seamlessly integrated into the industry's first network-within-a-network topology. This design provides maximum accessibility, security, and control for your IT infrastructure.

Public Network

Our Cisco™ driven redundant network offers carrier grade Internet connectivity to multi-home backbone carriers. This network is capable of gigabit speeds from the server to the Internet. You can also find bandwidth graphs inside the Customer Portal.

Private Network

Our private network facilitates complete control over server management while adding convenient and secure services. There are three functional areas to the private network:

Server-to-Server: If you have two or more servers with SoftLayer, these servers can communicate over a private connection at up to gigabit speeds on the same secure VLAN. Bandwidth is free and unmetered.
Server-to-Services: Your private VLAN and all connected servers have access to NAS, SAN, DNS resolvers, OS update servers, and more over the server backend network. This allows for fast, secure connections with free, unmetered bandwidth.
VPN to VLAN: True out-of-band management is possible through a distinct stand-alone third carrier over our SSL, PPTP or IPSEC VPN gateway. Simply launch a Web browser, type in the VPN address and you will be dropped into your private server backend VLAN. Use terminal services or SSH to gain access to your server over the private IP address or use the console software supplied in the Customer Portal to console directly into your server. Our VPN to the backend is an advanced method of server management and will give you control when your server has crashed, powered off, or any other state. You can also upload/download server files to and from your server over the secure VPN and without using your server bandwidth allotment because bandwidth is unlimited.

Data Center to Data Center Network

Provides free, secure connectivity between servers housed in separate SoftLayer facilities. You must enable Private Network Spanning in order for your systems in different private VLANs to communicate.
