Value-added Services

Managed ﬁrewalls

SMBs and enterprises with teleworkers

increasingly recognize the urgency of

protecting sensitive business information

transferred over the Internet. In fact,

network connections for remote

teleworkers are often the most vulnerable

links in an enterprise network. Often

lacking the IT resources to address their

security vulnerabilities, these customers

are a receptive audience for outsourced

security services. With the Siemens 5890

Business-class Router, service providers can

offer either a basic business ﬁrewall or an

optional ICSA-compliant stateful inspection

ﬁrewall for enterprise-grade security.

Service providers can quickly provision

highly secure VPNs using the conﬁguration

and management protocols that best ﬁt

their environment: HTTP, SNMP, SSH, or

Telnet. VPNs can be conﬁgured to support

Internet Protocol Security (IPSec) with

Internet Key Exchange (IKE), Triple Data

Encryption Standard (3DES), Layer 2

Tunneling Protocol (L2TP), and L2TP inside

of IPSec. By offering security services, the

service provider delivers additional value

over its existing infrastructure.

Quality of Service (QoS) for

teleworkers

SMBs and enterprises employ growing

numbers of teleworkers who need

reliable, secure high-speed Internet

access. This creates an opportunity for

service providers to manage swelling

trafﬁc volume, thus adding value to their

broadband services. The Siemens 5890

Business-class Router enables the service

provider to assign priority to speciﬁed

types of trafﬁc using IP Quality of Service

(QoS) features, such as DiffServ and

Weighted Fair Queuing (WFQ). Thus, the

service provider or its SMB customer can

offer the teleworker a separate service for

personal use, without affecting network

performance for business-critical tasks.

Flexible, secure management

Ease of management directly affects

service proﬁtability. The Siemens 5890

Business-class Router dramatically speeds

provisioning because business customers

can install and conﬁgure them without

assistance, using an intuitive, browser-

based interface. Role-based management

gives the service provider the ﬂexibility

to decide which functions the customer

can access and which remain under

the service provider’s exclusive control.

The ability to maintain users and roles

centrally, in a RADIUS database, reduces

the management burden as the service

grows. With simple, secure management,

the service provider can introduce its DSL

service for SMBs and enterprise teleworkers

more quickly, begin earning revenues

sooner, and scale rapidly to meet their

customers’ increasing demands for ease-of-

use and substantial functionality.
