Jitter Operations SLM
(SM-Pro-SLManager)
(SM-ProUpd-SLManager)
(SM-ProPlus-SLManager)
Solution Introduction & Details Overview:
This solution presentation focuses
on building and enforcing Service Level Agreements based in turn on performance
measurements capabilities built into the operating systems of all router
network devices which are essential in Managing Telecoms and Service Provider
backbone network’s service delivery to their prospective clients.
It introduces an SOSL based management script to build a
management process to monitor and ensure Service Level Agreement technology
concepts and requirements using the SNMP Protocol as an interface to
retrieve/poll Service Level Statistics data.
The solution presentation is based
on the ability of the management process to communicate with the particular
entity within the routers operating system in charge of measuring performance
metrics of certain applications performances, round trip delay and response
times, connection setup times, Packet losses, and inter-packet separation times
and variances in those separations. More metrics could also be supported
depending of the router device and the particular operating system software
image version as supplied by the particular vendor.
SLA is a formalization of a
pre-set and contracted quality of service delivery typically between the
service provider and clients.
