  capabilities
• Allows you to see where devices are on your
  networks
• Real-time MAC management
• Real-time upgrades to labeling and documentation
• Significantly decreases troubleshooting and fault
  detection

4

• Discovers all devices
• Logs all events
• Reports by object class, event type, location
• Triggers and escalates alarms or alerts via
  email, voice, page, messaging, cameras etc.
• Dispatches SNMP commands to switches or other
  network devices
• Enforces methodologies for best practice change
  control and management
• Extends third party, in-house, NMS, asset
  management, help desk

2. Better cabling

• Class F/Category 7
• Noise immunity
• Now approved for government installations that
  used to require conduit due to noise
• 10G Category 6
• Will really last 10 years
• Category 5e is not approved for this technology
• Shielded systems
• 50-micron fiber, laser optimized fiber
• Standards are now recommending Category 6 minimum

7
Why does this increase performance?

• Downtime is expensive
• Heartier cabling is less susceptible to problems
• Recabling is expensive and requires downtime
• Retransmissions increase latency and network
  traffic loads
• Auto-negotiation due to poor cabling can keep
  expensive electronics from performing as expected
• ANEXT is not an issue with shielded systems
• External noise such as factory machines are not
  an issue with shielded systems
• Initial investment is 5-7 of network costs, but
  poorly installed cabling is 70 of network
  problems!
• Any time you revisit your cabling you are
  investing in LABOR the most costly factor!

DCLCC cabling
NFPA codes and standards represent a set of
minimum fire safety requirements for the
protection of buildings
9
NFPA 90A is responsible for plenum spaces in
buildings

• NFPA 90A Standard for air conditioning and
  ventilation equipment
• Sets requirements for flame, smoke and fuel load
• 4.3.10.2.6 -- All materials exposed to the
  airflow shall be non-combustible or limited
  combustible and have a maximum smoke developed
  index of 50...
• Combustible (CMP, etc.) cables allowed as
  exception
• Requires listing of limited combustible cable

10
NFPA 70 is responsible for plenum cable products
and applications

• National Electrical Code (NEC)
• Recognizes hazards associated with cables in
  plenums
• Requires removal of abandoned cable from plenums
• Fine print note (FPN) points to NFPA 13
  requirements for plenum sprinklers with
  combustible loading

11
NFPA 13 standard for the installation of
sprinkler systems

• In sprinklered buildings, use of combustible
  cables in concealed spaces, including plenums,
  requires installation of sprinklers in these
  spaces.
• Use of limited combustible cable does not require
  sprinklers in these spaces.
• The options
• 1. Sprinklers in concealed space
• 2. Cable in conduit
• 3. LCC cable (most cost effective)

12
Why does this matter?

• May affect your ability to occupy the building
• Abandoned cable can deplete your cooling
  resources or cause an air dam
• In faults 95 is due to smoke only 5 is actual
  fire
• Fire spreads on parallel cabling

13
3. 10G Its here!

• Fiber-based options
• Utilize SMF or 50 micron laser optimized fiber
• Copper twisted-pair versions are in alpha
• Based on 10GBASE-T standard to publish in June
  2006
• Copper 10GBASE-CX4 products have been out for
  some time
• Predominantly in storage
• Limited to 15m (twinax)
• May be replaced by 10GBASE-T alternatives

14
Difference between copper and fiber

• Fiber does not auto-negotiate
• Copper will auto-negotiate between
  10/100/1000/10G
• Copper limited to 100m on augmented Category 6,
  Class F/Category 7
• Limited to 55m on legacy 6
• No support for Category 5e
• Fiber will be 10X the cost of a 1G fiber port
• Copper will be 3X the cost of a 1G copper port
• Photons versus electricity

15
10G early adopters

• Data centers
• Vertical infrastructures
• High-demand applications
• Graphics
• Simulations
• CAD/CAM/CAE
• Teleradiology and telemedicine
• New non-compressed video applications

16
Gigabit to the desktop

• All PCs come with Gigabit capabilities
• Chip costs have decreased significantly
• Many companies are already moving to gigabit
• Power users see immediate benefit
• Some are already 10G
• Provides additional throughput and decreases
  latency
• Saves on transfer times and increases productivity

17
4. Security appliances

• More than a firewall
• Examines port activity
• Can be in the NIC or at the switch

• Field-programmable gate arrays (FPGA)
• Utilizes pattern matching
• Specialized processors
• IPS/IDS
• Intrusion protection/intrusion detection
• SSL/VPN

20
5. Layer 7 products

• Build on QoS from Layer 3 by adding
  application-specific routing
• Can assist with bandwidth-hungry applications by
  providing specific routing based on priority as
  the application sees it
• Use content management such as HTTP headers, SSL,
  Session IDs, cookies and URI
• Distribute content and services among different
  servers to balance loads
• Can be proxy or transparent

21
Differences between proxy and transparent modes

• Proxy
• A single point of entry
• Centralizes security
• Consolidates logging
• Performance advantages
• Transparent
• Reverse of Web cache
• Can add some minor latency

22
6. Wireless In particular, WiMax

• Designed primarily for last mile
• Can offer increased performance for some
  last-mile and/or campus applications
• Still shared bandwidth
• Still wireless
• Can be operated in protected/licensed spectrum
• Part of IEEE BWA (Broadband Wireless Access)

Why consider blade servers?

• Reduced complexity
• Streamlined deployment and ease of management
• Scalable
• Increased density of processing power in smaller
  footprint
• Consolidated management
• Clusters with additional processing power
• Increased I/O at wire speed for all on same
  backplane
• Increased storage options

29
Differences between blades and traditional servers
30
8. Advancements in switching and routing

• Increased wire-speed processing
• Ethernet on the backplane work in progress in
  IEEE
• 10G switches and 10G uplink ports are available
  from most manufacturers
• Some include layer 7 capabilities
• PoE addition and significant decrease in costs
• PoE gigabit only works on end-span (power
  provided from the switch)

31
Better routing protocols and ELECs

• In many areas, WAN speeds are greater than LAN
  speeds
• Can be used to cluster resources
• Higher levels of traffic now move at increased
  speeds
• Greater competition in this space has allowed for
  greater functionality
• Ethernet local exchange carriers mean
  conversions/encapsulations are now avoidable

32
9. VoIP and IP telephony

• Its not new, but is being readily adopted
• E911 is still an issue
• Product sets are proving to be more scalable and
  interoperability is increasing with SIP and
  product maturity
• 75 of voice traffic expected to be VoIP by 2007
  (IDC Research)

33
VoIP and IP telephony

• IPT includes things such as fax, universal
  messaging, etc.
• Takes voice and samples it into packets for
  delivery across a network
• Provides a significant cost savings to companies
  especially office to office
• Needs some type of gateway to the POTS network

34
VoIP and IP telephony

• Switch may be in phone, may be separate cable
• Standards recommend two outlets per work area
• One for phone, one for PC in this case
• If switch is in phone, cable channel becomes
  shared media
• Phones may be powered via data cable
• Voice traffic is sensitive and requires
  dependable bandwidth
• Video conference may be part of system
• Category 7 cable allows PC and phone to operate
  at 10/100 over one single cable
• New wireless IP phones are being introduced

35
Routing for VoIP

• Call is digitized in phone
• Each packet is about 20ms of voice
• Packets move to IP PBX
• If in house, sends packets to other phone
• If out of house and on VoIP system, sends call to
  other system
• If not in house, not VoIP moves to POTS network

36
Universal messaging

• Part of SIP
• Calls can follow a user
• URL dialing
• Voice mail in e-mail
• Voice system can read you your e-mail
• Single connectivity solution for messaging

37
VoIP and the LAW

• Is it data?
• Is it voice?
• Public service commissions seek tariffs
• EU says quality is too poor to regulate like
  PSTN/cell
• Origination of call is tariff point
• How do you track this with mobile workforces?
• SIP allows location by URL
• Internet allows calls to originate anywhere
• Similar to proceedings from cable industry
  several years ago

38
Using the switch in the phone

• Cost of phone (average retail) 360.00
• Avg. cost of not running a new cable - 150.00
• Stated cost of phone after savings 210.00
• Cost to replace phone once over lifetime of
  system 360.00
• Actual cost with one replacement (210.00
  replacement) 570.00
• Average cost of running an additional
  cable 150.00
• Average cost of phone without switch 200.00
• Average cost of one replacement over lifetime of
  cable 200.00
• Total cost with additional cable 550.00

39
10. Grid computing
40
Whats a grid?

• The ability to group/cluster many systems
  together to increase processing power
• Do not have to be the same computers
• Reaching mainstream corporate environments
• Share processing loads
• Share storage pools
• Virtualization is a great fit for this technology
• Can process requests remotely and send solution
  sets

41
TeraGrid Open scientific computing
42
Allows shares of significant data stores

• Full image of the earth once every 24 hours
• Some are a terabyte in size
• Lawrence and Berkley labs built a grid out of PCs
  that nearly equaled the processing power of a
  small Cray for under 20k
• Becoming an option for large ERP/CRM systems
• Check out www.top500.org for a listing of
  resources
