Overview SLA

SLA (Service Level Agreements) calculates the related parameters according to the packet transmission and outputs the report at last. SLA, also called RTR (Response Time Reporter), is one network detection and monitoring tool. SLA regularly sends the packets of the specified protocol to detect and monitor the network communication. SLA can diagnose different network applications and output the test result by configuring different types of RTR entities and adjusting.

SLA basic concepts:

• RTR Entity: RTR Entity is one universal concept and not related with the specific type of RTR entity. The current RTR entity types of the system include: the ICMP-echo entity, ICMP-path-echo entity, ICMP-path-jitter entity, and UDP-echo entity used to detect the network communication; the VoIP-jitter entity used to detect the network transmitting the VoIP packets; the FLOW-statistics entity used to detect the interface traffic.
• LSP-ping entity: Used to detect the MPLS network communication
• RTR Group: One RTR entity group is the set of one or multiple entities;
• RTR responder: The RTR responder is configured at the destination, mainly used to set up the connection with the source and respond the detection packet sent by the source. Most entities do not need to configure the responder, but when using the UDP-echo entity and VoIP-jitter entity, we should configure the responder.
• RTR Schedule: If only configuring the RTR entity or RTR entity group, we cannot detect, but should initiate the scheduling so that the detection can be completed.
