Value-Added Services
Managed rewalls
SMBs and teleworkers increasingly
recognize the urgency of protecting
sensitive business information transferred
over the Internet. Often lacking the
IT resources to address their security
vulnerabilities, these customers are a
receptive audience for outsourced security
services. With 5930/5935 ADSL Business
Gateways, service providers can offer
either a basic business rewall or an ICSA-
compliant stateful inspection rewall for
enterprise-grade security (gure 1).
Service providers can quickly provision
highly secure VPNs using the conguration
and management protocols that best t
their environment: HTTP, SNMP, SSH, or
Telnet. VPNs can be congured 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. A VPN accelerator increases IPSec
3DES VPN throughput to up to 8 Mbps.
By offering security services, the service
provider delivers additional value over its
existing infrastructure.
Quality of Service (QoS) for
enterprise teleworkers
SMBs employ growing numbers of
teleworkers who need reliable, secure
high-speed Internet access. This creates
an opportunity for service providers to
manage swelling trafc volume, thus
adding value to their broadband services.
SpeedStream 5930/5935 Business
Gateways enable the service provider
to assign priority to specied types of
trafc 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
(gure 2).
Flexible, secure management
Ease of management directly affects
service protability. SpeedStream
5930/5935 Business Gateways speed
provisioning because business customers
can install them without assistance, using
an intuitive, browser-based interface.
Role-based management gives the service
provider the exibility to decide which
functions the customer can access and
which remain under the service provider’s
exclusive control (gure 3). And 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 ADSL
service for SMBs and teleworkers more
quickly, begin earning revenues sooner,
and scale rapidly.
