Route
Explorer can be deployed in a distributed, multi-appliance
architecture consisting of:
- Route Recorders: Streamlined appliances that
are geographically distributed to monitor and
record routing activity in one or more routing
domains (e.g., IGP areas or BGP ASs), and forward
routing data to a Modeling Engine for interactive
analysis. Route Explorer appliances can also
be deployed where a local user interface is
required.
- Modeling Engine: A centralized appliance that
synthesizes routing topologies collected by
distributed Route Explorer and Route Recorder
appliances, and provides unified monitoring,
analysis and modeling of network-wide routing
activity.
Key Features and Benefits of Distributed
Route Explorer:
- Increases network management availability
and continuity by geographically distributing
route recording appliances,. If a network error
or partition leads to loss of connectivity between
a Modeling Engine and a remote Route Recorder/Route
Explorer, the remote appliance continues to
record locally.Even though the Modeling Engine
will temporarily lose visibility to the remote
appliance’s portion of the network during the
partition, full routing history is resynchronized
to the Modeling Engine once connectivity is
restored.
- Supports any combination of global and regional
network management domains. If Route Explorer
appliances are distributed for route recording,
their local graphical user interfaces allow
for local monitoring of each routing domain.
If a local GUI is not required, Route Recorders
provide a lower-cost option for distributed
route recording with a centralized interface.
- Offers flexibility for a range of route analytics
deployment models, including redundant Route
Recorders per routing domain, and multiple Modeling
Engines to support more users or provide fault-tolerance.
- Meets the needs of organizations with multi-tiered
and regionalized network management domains.
- Supports network deployments where GRE tunneling
is not available.
