New Features

The OCSLB S-Cz8.3.0m1p2 release provides system and performance enhancements over prior release versions. This section also list new customer-facing operational features.

Bidirectional Forwarding Detection

The OCSLB supports Bidirectional Forwarding Detection (BFD) over Acme Packet 6100 network interfaces. BFD is a network protocol used to detect faults between two forwarding engines connected by a link. It provides low-overhead detection of faults, even on physical media that doesn't support failure detection of any kind, such as Ethernet, virtual circuits, tunnels and MPLS Label Switched Paths. You configure BFD for functions, including gateway path verification.

See the "System Configuration" chapter in the ACLI Configuration Guide for explanations of BFD support and configuration on the OCSLB.

SLB Balancing based on Proportional Capacity

The OCSLB supports balancing based on proportional capacity on target OCSBCs. This balancing strategy causes the OCSLB to maintain a calculation using the registration cache limit and the current endpoint count on each applicable OCSBC. You configure the OCSLB to distribute traffic via this calculation by configuring the new lbp-config, strategy parameter to capacity-proportional. By default, strategy is set to least-occupied, which balances based on registered endpoints and ignores registration cache size.

See the "Overview" chapter in the OCSLB Essentials Guide for explanations of Proportional Capacity support and configuration on the OCSLB.
