IP SLA Management and WAN Link Monitoring
Monitoring availability, reliability and performance of WAN links (logical connections between two geographically distant network hosts) is essential for all enterprises. We'll try to be succinct here. Remote branches of large multi-office corporations will seriously suffer if elements of IT infrastructure located in the HQ will be unavailable. Those corporations rarely own WAN channels – these channels are normally rented from telecom operators. All channel quality complaints will be forwarded to the telecoms who will obviously need even better link monitoring service for proactively solving quality degradation issues and planning capacity.
AggreGate Network Manager offers different methods of WAN link monitoring:
The status and performance of monitored links can be visualized on network overview dashboards and geographical maps created in the integrated UI Builder.
Basic Monitoring: Ping and Route Tracing
The simplest WAN Link monitoring tools are ping and traceroute commands known to any network administrator. The Network Manager can automate such basic monitoring by:
IP SLA Monitoring and Management
Cisco IP SLA technology enables Cisco routers and switches to perform various network tests by exchanging simulated data with other Cisco devices ("responders") or ordinary network hosts.
IP SLA ensures monitoring of
The Network Manager fully supports the following IP SLA test types: ICMP Echo, ICMP Path Echo, UDP Echo, TCP Connect, UDP Jitter, ICMP Path Jitter, VoIP Call, RTP, DNS, DHCP, FTP, HTTP.
AggreGate Network Manager is the only product allowing to build custom tests through the central monitoring server by manually specifying a test protocol and all configuration parameters (over 50 parameters in total).

Probe-based WAN Channel Monitoring
AggreGate Network Manager can collect network link measurement statistics from diverse network probes. Those probes can be custom-build hardware devices or software applications (usually running on industrial or micro PCs) from different manufacturers. Most of probes support SNMP making their integration with the network manager extremely quick and easy. However, the underlying AggreGate IoT Platform ensures that all possible data collection methods are supported (see connectivity).
Probe-based monitoring has its own advantages:
