is Quality of Service (QoS)
of Service (QoS) provides a stable and predictable
data transmission service that satisfies different
applicationsˇ¦ requirement. Although it doesnˇ¦t
create a new or larger bandwidth, it relies on
the requirement of application or the network
management settings to provide manageable bandwidth
was the problem with network transmission service
in the past?
Protocol) was designed to provide network transmission
service from point to point. It is used on OSI
Layer 4 and above, such as TCP to acknowledge
the recipient of data packets. However it does
not provide the protection of bandwidth, it is
simply a ˇ§best effortˇ¨ try-its-best solution.
This is acceptable for transmission such as Web,
Email and FTP as the delay is hardly noticeable,
but not for ERP, E-Commerce, VoIP, VoD or any
other service that require a more instant transmission.
is never enough when dealing with multimedia
transmission, large file downloads etc. It is
not justifiable to increase bandwidth just because
important data are queuing behind the less important
ones and cannot be transferred on time.
Queuing, Policy Management or queuing type products
may increase the efficiency of the network. However
it does not guarantee a consistent response time
for important network services. QoS has this
ability to optimize the bandwidth, and provide
manageability of network traffic.
do you choose a QoS product?
the QoS equipment hung for any reason, it
should have the intelligent to allow data
to continue being transferred, even though
QoS functionality is lost. Also, a QoS equipment
should not require reconfigurations of usersˇ¦
computers or routers.
