Encryption support for algorithms like DES, 3DES, and the Advanced Encryption Standard (AES) provides ultimate
end-to-end security for transmitted data.
Authentication support for protocols like RADIUS, LDAP, secure ID, and X509 as well as token and smart card
support and directory-based services are important factors for SME routers.
Stafefull firewall and secure routing services using standard protocols like Open Shortest Path First (OSPF), Routing
Information Protocol (RIP), Network Address Translation (NAT), and industry standard data link switching services
to transport traffic over the public or private IP networks, using the encryption and tunnelling protocols discussed
previously, also need to be considered.
Bandwidth management and Quality of Service (QoS) provide the ability to deliver on the promise of highly
optimized IP networks. With advanced services—Differentiated services (Diffserv) and other sophisticated queue
management—it is critical that an SME router ensure service levels are met for any mission-critical data. Hence,
solutions must support the prioritization of traffic not only by IP traffic type, but also by prioritized users, groups
and VPN tunnels allowing for a very fine granularity in (QoS) and even Class of Service (CoS) must be supported.
Also in multi-user environments the ability to support minimum guaranteed bandwidth for a user or set of users.
LAN/WAN flexibility to support Ethernet, frame relay, PPP, T1/E1, V35, X21, ADSL, VDSL, ISDN, V90 as well
as wireless broadband connectivity such as 802.11 and even over time 802.16 will become key requirements. On the
WAN side, the main layer two protocols used are frame relay (FR), asynchronous transfer mode (ATM) AAL5 over
ADSL, integrated services digital networks (ISDN), dial up, and leased line. On the Lan side, the main layer two
protocol used is Ethernet and the key requirement is to eliminate the need for an Ethernet switch or hub in a small
office environment, while medium sized offices may include an Ethernet switch or hub. In addition, wireless LAN
802.11 can also be deployed to provide mobility to users within the office environment.
In summary, the specific design challenges for SME routers include the following:
Increasing number of different network interfaces
Convergence towards IP packet based networks.
Switching, interworking, parsing, and forwarding of multiple protocols
Managing bandwidth and QoS to ensure prioritization of latency sensitive traffic, such as voice or
guaranteed bandwidth per user
Excellent virtual private networking and advanced security features that support legacy and new emerging
standards and requirements
Providing flexibility to add new features and functions through in-field software upgrades as market
demands dictate
The successful SME solution must provide a balance among system implementation, power dissipation, physical
size, Printed Circuit Board (PCB) area coupled to system performance, the appropriate software, and cost
effectiveness. However, equipment manufacturers face the challenge of providing more system performance,
flexibility, and features without inflating system costs, power dissipation, or PCB area. As a result, a cost-effective
alternative to expensive ASICs, FPGAs or NPUs is needed to meet these demands.

Freescale Semiconductor Solutions
In the competitive SME router market, highly integrated, cost-effective and scalable system solutions are required.
With these system requirements in mind, Freescale is pleased to introduce the latest addition to its popular
PowerQUICC family of microprocessors—the PowerQUICC II Pro MPC8358E.
