Circuit bonding can also provide redundant diverse path protection. It maps client
information onto a set of line-side transmission paths. By using physically diverse routes,
a circuit-bonded system can offer path protection. Circuit bonding reacts very quickly to
failures and automatically performs ???load sharing??? across all available paths well within
the MEF-required 50??“ms timeframe. This capability allows a service provider to offer
protected off-net or on-net Ethernet service without the cost of SONET transmission.
Hard QOS/Throughput One of the primary strengths of packet networking, such as
Ethernet, is that statistical multiplexing becomes possible. This greatly increases the
bandwidth efficiency of networks. A typical customer requires the bandwidth to transmit
data in minimal time. Because of expense, it is very difficult to provide customers
with a full-time, fast end-to-end network. Fortunately, most customers do not require
the maximum bandwidth be available all the time. Because of this, packet networks
that allow some of the resources to be shared can be utilized. Each Ethernet segment is
capable of a maximum bit-rate based on the physical layer transmission medium.
