Complete
Inline WAN and OC Monitoring
WAN Probes monitor all header and payload data
on serial and digital WAN links. Choose to monitor
up to 16 links individually or in aggregate, obtain
metrics in real time, and solve issues immediately
with a comprehensive Expert system. Probes also
display DCE/DTE traffic individually or in aggregate,
shows CIR to compare with SLA, and tracks conversations
through up to 10 segments or hops.
Observer WAN Analysis Advantages
 Wide
Area Network (WAN) connectivity and throughput
validation is a key part of a healthy, cost-effective
remote connectivity strategy. With WAN costs typically
accounting for the majority of the network’s ongoing
operating budget, tracking performance is critical.
The Observer WAN solution provides in-depth metrics
for comprehensive WAN flow analysis, making WAN
testing and monitoring as easy as monitoring local
resources.
WAN Analysis Advantages
- Manage and monitor VoIP and UC systems with
expert analytics
- Monitor up to 16 connections individually
or in aggregate
- Monitor CIR to verify and enforce Service
Level Agreements
- Perform packet captures, review statistics
that adhere to RMON1/RMON2 and HCRMON
- Capture and decode WAN encapsulation and payload
data
Observer WAN Solution Features
 Multi-Hop
Analysis
- Track conversations through up to 10 segments
- Pinpoint network delay or system processes
as cause
- Measure one-way, round-trip, and individual
hop delay
WAN Vital Signs
- Get comprehensive summary of WAN errors, stats,
utilization, congestion
- View DCE/DTE traffic individually or in aggregate
- Stats shown in packets, bytes, FECNs, BECNs,
number of discard eligibility, errors, and utilization
Plus WAN alarms, filtering, trending, reporting,
real-time experts and more.
T1/E1/DS3 Support
For organizations looking to monitor and troubleshoot
fractionalized and non-fractionalized T1 lines
and more, rely on Observer’s WAN analysis. For
example, monitor Internet or site-to-site connectivity
for your local and remote offices.
With Observer WAN Analysis:
- Monitor up to 16 links individually or in
aggregate
- Ensures full-duplex capture on serial HSSI,
digital T3/DS3/E3, and serial and digital T1/E1
- Localizes processing at the probe to minimize
network overhead
- Reports to any Observer Expert or Observer
Suite console
For T1/E1/DS3, we support protocols including
Frame Relay, Point-to-Point protocol (PPP), HDLC,
and more.
Full OC3 and OC12 Support
For large organizations and carriers monitoring
OC topologies, Observer now monitors and analyzes
OC3 and OC12 traffic and decodes OC-related protocols.
 While
the OC transfer scheme introduces an element of
uniformity, it also creates a certain amount of
network overhead.
ATM is a dedicated-connection switching technology
that organizes digital data into 53-byte cell
units and transmits them over a physical medium
using digital signal technology.
Observer supports Packet over SONET (POS) and
asynchronous transfer mode (ATM) over OC.
Expert analysis helps you quickly determine the
potential source of the problem. Observer provides
40+ unique ATM experts to aide you in resolving
WAN issues. For example, Observer can determine
if errors are caused by cell loss, severe congestion,
and many other ATM-specific indicators.
