Mirroring Performance

Replication of mirrored packets can, typically, affect performance and should be used carefully.

Alcatel-Lucent 7750 SR routers minimize the impact of mirroring on performance by taking

advantage of its distributed Flexible Fast Path technology. Flexible Fast Path forwarding allows

efficient mirror service scaling and, at the same time, allows a large amount of data to be mirrored

with minimal performance impact. When a mirror destination is configured, the packet slice

option can truncate mirrored packets to the destination, which minimizes replication and tunneling

overhead. The mirroring architecture also supports mirror rate limiting both at the ingress and

egress Flexible Fast Path NPA. This rate limiting is accomplished though a shaping queue and is

set according to the maximum amount of mirroring desired.

Mirroring can be performed based on the following criteria:
