Traditional Design
Floor 1..Floor x
Design Issues At layer 2 these extra links need
to be blocked to prevent network loops. This is
usually implemented using a protocol called
spanning tree (802.1d) Spanning tree protocol
prevents these loops by deciding the best links
to use and blocking all the rest. Basically
youre paying for stuff you cant use !

Two-Tier Infrastructure design
Edge High density 10/100 Ethernet ports for user
connections and Gigabit Ethernet for riser
connections. Access security controls and QoS
mapping.
Core High Density Gigabit Ethernet for riser
connections. ATM, SONET and Optical connections
for MAN/WAN access and L4-7 Applications
switching for Data Center integration.

S-MLT Link Aggregation
  • Split Multi-Link Trunking
  • A Fresh approach to the spanning tree problem
  • Description
  • Edge switches normally dual-homed for resilience.
  • Current network rules mean that one connection
    must be blocked.
  • Split MLT makes two core switches act as one.
  • Now both Links are active and appear as one.
  • Advantages
  • Fail-over reduced to lt1sec
  • No wasted - You can use what you pay for!

Optical Metro Solution
17
Metro Bandwidth Challenge
  • New multimedia applications require more
    bandwidth
  • Multi channel Gigabit metro solution is the
    answer, but
  • Normally this would require
  • Multiple expensive leased fiber runs for
    resilience or
  • Expensive and complex DWDM equipment to reduce
    fibers
  • Challenge is to provide High bandwidth services,
    while.
  • Keeping leased fiber costs to a minimum
  • Without wasting fibers (dead sparing)
  • Maintaining reliability (Application state)
