1.3.2.    If you’re at all typical, all the major trends in
          networking—involving increased requirements
          for services—are at work:

          desktop applications—with different priorities
          and bandwidth demands—increase the need to
          allocate your available network bandwidth.
1.3.5.    And there’s a dramatic increase in the need for      (Button 1 submenu: Drivers of Networking    NAV=Seq. Cont. to 1.3.7
          both internal and external access control,           Requirements)
          especially as Internet access skyrockets and         Seq. #11: Security
          remote computing multiplies.

1.3.8.    However, a fundamental and more pressing             Show Transaction Processing pipe
          requirement is guaranteeing that applications
          such as on-line transaction processing are
          allocated sufficient bandwidth and appropriate
          priority. This can be critical in order entry or
          inventory management situations where response
          times are of the essence.

2.2.2.    Route Processing is the function in which routers
          decide where to send traffic. Usually it does this
          by running a routing protocol, such as IGRP.

2.2.5.    Beyond route processing and network switching,      Build-on Network Services                     NAV=Click Next
          routers perform network services including
          access list checking and protocol translation. As
          with Network Switching, these are called
          "network" services not just because they’re done
          within the network, but because they’re applied
          based on information at the network layer.
2.2.6.    This includes so-called "low touch" services that
          involve just looking at network traffic—such as
          checking access lists and performing traffic
          accounting... and also "high touch" services,
          which let you directly manipulate payload data,
          as is done in encryption or compression.
2.2.7.    "High touch" services are becoming increasingly
          important as the need for more sophisticated
          network services grows. Software and processor-
          based switching systems are ideally suited to
          perform "high touch" network services.
2.2.8.    Cisco’s new NetFlow Switching is a software-         (Button 2 submenu: High Performance          NAV=Seq. Cont. to 2.2.9

2.2.13.   Looking at the mechanism used in conventional         (Button 2 submenu: High Performance    NAV=Seq. (Anim) Cont.
          switching, we see how its processing of network       Network-layer Switching)               To 2.2.15
          services as separate tasks for each packet creates    Seq. #21: Conventional switching       Slow down animation
          a load on system performance. In some cases,                                                 slightly

          this overhead causes users to forego these
          services in favor of performance.
2.2.14.   Plus, it isn’t often practical to extend the                                                 NAV=Click Next
          granularity with which services are applied
          beyond network-layer addresses, in order to
          distinguish between specific applications.

          determine its path, security provisions, queuing
          priority, and traffic information.
2.2.16.   These attributes are cached so that switching and
          services for a given flow are performed in
          tandem, with high efficiency, whenever
          subsequent packets in the same flow are
          received. It is this dramatic simplification of
          packet processing that gives NetFlow greater
          performance for application of services.
2.2.17.   And what exactly constitutes a flow? A flow is a
          uni-directional stream of traffic from a specified-
          source, network-layer address and transport-
          layer port number to a corresponding address
          and port. Since most applications use well-
          known transport-layer port numbers, it is this
          granularity in NetFlow Switching that allows
          services to be applied on a per-user, per-
          application basis.
2.2.18.   Since flows are identified within the router, and
          no connection setup protocol is required between
          routers, NetFlow Switching is completely
          transparent—no external changes are required to
          your network, to the packets themselves, or to
          any other network device. All you need is a
          software upgrade.
2.2.19.   And because NetFlow Switching is done
          independently on each individual
          internetworking device, you don’t need to make
          it operational on every router in your network.
2.2.20.   When you do turn on NetFlow Switching, the                                                   NAV=Click Next to return

2.3.2.   By contrast, applying these services in
         conventional switching can degrade system
         performance by up to 50 percent. This
         sometimes means users choose to leave these
         services turned off.
2.3.3.   When you turn on NetFlow Switching, you’ll see                                                     No Chart

         performance behavior depends more on the
         number of flows than the aggregate amount of
         traffic, and on other traffic characteristics,
         including the number of packets-per-flow.
2.3.5.   NetFlow Switching is software-based, so you              (Button 2 submenu: Performance and        NAV=Seq. cont. to 2.3.7
         can start using it on most Cisco routers with just       Platform Support)

         systems with Route Switch Processors. It will
         also be extended to Cisco’s other RISC-based
         routers, beginning with mid-range systems.
         NetFlow Switching currently supports traffic
         using Internet Protocol (IP) and will be extended
         to handle IPX as well.
2.3.7.   On Cisco 7000 and 7500 systems, NetFlow                  (Button 2 submenu: Performance and

2.3.9.   How well does NetFlow Switching increase the
         performance of network services? The gains can
         be substantial. In fact, using NetFlow Switching
         with VIPs on a distributed basis can boost
         services performance on a 7513 system to over a

2.4.2.   For example, this table is a snapshot of traffic,       Zoom into stats (magnifying glass)

         40-hour period. In it, you can see:
2.4.3.   • That Web traffic accounts for about 50 percent
         of identified flows, with an average of 225 new
         ones created every second;
         • That web traffic generates relatively few
         packets-per-flow compared to Telnet, FTP and X
         sessions, but that bytes-per-packet is high;
         • That in spite of the numbers of total and active
         flows—around 58 million and 30,000
         respectively—the average switching
         performance load was only about eight thousand

         NetFlow Switching generates individual                  column headers
         statistics for each active flow—on this router
         there are about 30,000. For each one, you can see
         total packets, bytes-per-packet, flow duration in
         seconds, and incoming and outgoing interfaces
         on each router.
2.4.5.   This unparalleled level of information is a
         powerful tool to help you design and manage

         infrastructures, Cisco is continuing to expand the   router. No zoom out. As bandwidths are
         capabilities of Cisco IOS software with support      discussed, pipes change size accordingly
         for a variety of protocols and queuing methods.

         Resource Reservation Protocol, or RSVP. It
         enables applications to request a specific quality
         of service across a network. In routed
         environments, these requests require routers
         along a path to confirm a specific quality of

         transmitting secure data, especially compared to
         link encryption. And since it’s independent of

3.5.3.    Network Encryption uses a scalable public key
          method that automatically exchanges encryption
          keys for each session. There are two
          versions—using the DES encryption
          algorithm—to satisfy import and export
3.5.4.    This Cisco IOS Network Encryption service is
          supported on Cisco routers from the 2500 series
          at remote sites to the 7500 series at central sites,
          and needs to operate only at network endpoints.
3.5.5.    Cisco also offers a hardware-based encryption
          port adapter for its new Versatile Interface
          Processors, for environments that require very
          high encryption performance.
3.5.6.    To better understand the benefits of Network                                                           NAV=Click Next
          Encryption, let’s take a closer look at the ways
          encryption can be performed.
3.5.7.    Encryption can be performed by programs on             (Button 3 submenu: Network Encryption)          NAV=Seq. Cont. to 3.5.10
          workstations and hosts at the application layer.       Seq. #36: Encryption Alternatives
          The advantage here is that it operates on a
          complete, end-to-end basis. However, not all           Top view tilts to reveal layers. The
          applications support encryption, and since this        workstations represent the application layer.
          kind of encryption is usually controlled by            Highlight the three layers at which
          individual users, it isn’t completely reliable.        encryption can be performed, as they’re
                                                                 discussed by VO.
                                                                 Video: Packet Flow Encryption
3.5.8.    Encryption can also be performed at the network        Hold multi-layer diagram on screen
          layer by general networking devices, for specific      Remove the packet flows
          protocols. This has the advantages of operating
          transparently between subnet boundaries and
          being reliably enforceable.
3.5.9.    Finally, encryption can occur at the data link                                                         NAV=Click Next
          layer by specific encryption devices, for a given
          media or interface type. The main advantage
          here is protocol independence, but it has to be
          performed on a link-by-link basis.
3.5.10.   Link layer encryption encrypts all traffic on a        (Button 3 submenu: Network Encryption)          NAV=Seq. Cont. to 3.5.13
          given link, including network-layer headers and        Seq. #37: Link Encryption
          protocol information. This makes it protocol-
          independent, but in order to accommodate link          Fade back the routers to indicate that when
          layer variations, it must be media/interface           using link encryption you don’t need to
          specific.                                              encrypt at other layers—show all traffic
                                                                 encrypted on network
                                                                 Video: Packet Flow Encryption
3.5.11.   So, every link the encrypted traffic might pass
          through has to be encrypted and decrypted
3.5.12.   The usefulness of link layer encryption therefore                                                      NAV=Click Next
          depends almost entirely on a network’s topology.

3.5.13.   By contrast, network encryption encrypts on a        (Button 3 submenu: Network Encryption)       NAV=Seq. Cont. to
          flow-by-flow basis, and operates only on             Seq. #38: Network Encryption       
          payload data— packet headers are left
          untouched. This makes the encrypted traffic          Show that only a specific flow becomes
                                                               encrypted—all other traffic remains clear,
          transparent to any intermediary network-layer
          devices.                                             and all traffic travels freely

3.5.14.   Because it operates at the network layer, network                                                 NAV=Click Next
          encryption is protocol specific, but media,

         increased bandwidth performance. By using a
         common motherboard that can be equipped with
         a variety of media and interface types, and
         plugging in modular port adapters, these new
         VIPs significantly improve your operational
         flexibility and reduce costs.
4.2.3.   This modularity lets you mix and match                VIPs chart                                NAV=Click Next

         multiple, specific media and interface cards, you
         can now stock generic VIPs and selected port

         conjunction with the new VIPs, switching              Chart builds
         performance scales to over a million packets-

         higher port densities, so that with new high-
         density port adapters, the capacity of the 7513 is
         doubled, to nearly 200, ten-megabit ports!
4.2.6.   Cisco’s new generation of VIPs supplies the           Chart stays on
         processing performance needed for high capacity
         distributed switching. And performance of
         services on a distributed basis allows them to be
         applied in a highly scalable way.
4.2.7.   This combination of NetFlow Switching and
         distributed services, with VIPs enhancing
         capacity, is an example of the extensibility of the
         7500 platform, which Cisco will continue to
         expand. A further example of this extensibility is
         Cisco’s Packet OC3 card.
