Randstad deployed an end-to-end Cisco® solution to support the new network, 
which it internally calls SpeedLink. With Cisco, Randstad Deutschland was able to 
use the Internet instead of expensive business lines, and at the same time realize 
the cost benefits of provider flexibility.
At Randstad’s data center, four Cisco ASA 5500 Series Adaptive Security 
Appliances provide secure, high-performance connectivity. Cisco ASR 1000 
Series Aggregation Services Routers handle edge routing services, while Cisco 
Integrated Service Routers 800 and 890 Series route connectivity to the main 
office in Eschborn. At branches, Cisco Integrated Service Routers 2900 Series 
distribute bandwidth from redundant cable, DSL, and 4G/LTE uplinks. Management 
is simplified with Cisco Prime™ Infrastructure, which provides lifecycle management, 
application visibility, security and policy monitoring, and troubleshooting capabilities.
“We chose Cisco for our network because of the breadth of solutions Cisco offers, 
as well as the manageability benefits,” says Schultheis. “Expertise with Cisco 
solutions is easy to find, and we knew we’d be able to manage it with a relatively 
small team.” 
Randstad’s SpeedLink network uses Cisco Locator/ID Separation Protocol (LISP) 
to simplify routing operations. By separating a device’s endpoint identifier (EID) and 
its routing locator (RLOC) into two different numbering spaces, the LISP routing 
architecture optimizes IP routing for both IPv4 and IPv6 hosts. “Cisco LISP is an 
open standard that allows us to use short and simple configurations, reducing 
operational complexity and cost for our network,” says Schultheis.
The SpeedLink network uses Cisco Group Encrypted Transport VPN (GETVPN) to 
provide VPN service without tunnels. This approach enables direct communications 
between branches without requiring transport through a central hub, providing 
optimum bandwidth efficiency while securing communications. GETVPN also 
improves management flexibility by eliminating complex peer-to-peer key 
management with group encryption keys. “Cisco GETVPN gives us a strong 
encryption standard, and the tunnel-less architecture helps us maintain VPN 
connections even when there are packet losses on the Internet,” says Schultheis.
Randstad Deutschland also deployed Cisco Unified Communications Manager along 
with Cisco Unified IP Phones 7962 for enterprise-class IP telephony. Cisco Unified 
MobilityManager works with Cisco Unified Communications Manager to deliver 
services such as Cisco Mobile Connect for single-number reachability. “Cisco 
Mobile Connect is a great failsafe for us if there is an interruption in Internet service 
at a branch,” says Schultheis. “We can simply route calls to employees’ mobile 
phones, so customers can still reach us.”
To gather information on network performance at both ends of the network as well 
as at the IP layer, Randstad uses Cisco IOS IP service-level agreements (SLAs). 
Cisco SMARTnet® Service gives Randstad 24-hour access to experts in the Cisco 
Technical Assistance Center (TAC).
