Session Accelerator Module for the Cisco CSS 11500 Content Services Switch
The session accelerator module is a cost-effective way to add flow performance when additional connectivity is not
required. Using the same flow setup and forwarding processors as the I/O modules, it provides the flexibility to
optimize the system for port density and performance. Table 1 gives the features of the Cisco CSS 11500 models.
