Example Network Elements

ATCA* NPU blades can be used in a wide range of access/edge equipment

– Multiservice switch (MSS)– Modular secure content processing– Wireless– And many others (DSLAM, CMTS,…)

Good targets– Heterogeneous networking– Heavy protocol processing– Technology change


23

MSS Technology EvolutionMSS are based on ATM, Frame Relay, IP routers, typically in proprietary modular form factorDedicated ATM & FR switches are evolving to flexible, configurable, scalable platforms – Multi-Service SwitchesFewer base boxes with more service options per box

– Traditional stand-alone platforms become option blades added to a Multi-Service Switch: ATM Switches, IP/Edge Routers, VoP Gateways, Wireless Gateways

MSS System RequirementsMultiple physical interfaces

– SONET – OC-12, OC-48, OC-192, … – Ethernet – Gig and 10Gig– DS-1, DS-3, …..

Multiple data link layers– ATM, Frame relay– PPP– Ethernet (L2)

Multiple “services”– ATM, FR, IP, and MPLS switching – VoATM, VoIP, circuit emulation – wireless aggregation, DSL aggregation– VPN gateway services– QoS and CoS for delay sensitive traffic– Goal is ASAP – Any Service Any Port

Secure Content ProcessingDefinition

– Inspection and transformation of packet data as well as packet headers to perform network services

Examples:– Simple firewall examines IP addresses (header) and the

session requested, such as ftp, http,… (data)– VPNs encrypt and encapsulate Intranet packets (header and

data) inside Internet packets – Load balancers (L4-7 switches) examine session data to

determine the best destination to use, then modify address header accordingly

27

NPUs in Secure Content Processing Solutions

IA is the platform upon which many of the preeminent security applications now run. IXPs provide an opportunity to accelerate the performance of many of these applications to support higher security and line rate demands.

– Evolution to gigabit and beyondATCA* enables development of bladed security plaforms with high performance/availability etc.


28

Example Secure Content Processing Cards

POS / POS / Ethernet Ethernet Line CardLine Card

Ingress / Egress Card – ATM, POS, Ethernet– Terminates WAN and LAN connections– Performs layer 2-4 processing, forwarding, etc– Optionally includes crypto capability via Intel®

IXP2850 or crypto co-processor

Layer 4-7 Processing Card– Intel® Pentium® based compute resource using

standard operating system and network stack– Performs control functions and higher level

protocol processing– L4-7 switching– Firewall– Intrusion detection– Routing control
