Function
Allows applications on any card to share the same TCP/SCTP connection
to the same remote endpoint instead of opening a new connection for each
application on the card.
Manages physical chassis components.
Maintains all global CSS properties which include a list of CSS servers
that can be bound to a service in a context.
CSS defines how traffic will be handled based on the "content" of the data
presented by or sent to a mobile subscriber. CSS encompasses features
such as load balancing, NAT, HTTP redirection, DNS redirection.
The content server (services) can be either external to the platform or
integrated within the platform. External CSS servers are configured via the
Context Configuration mode css server command.
The CSS Controller does not create CSS Managers. CSS Managers are
stopped and started by VPN Managers. A CSS Manager is automatically
created for each context.
Spawned by the VPN Manager within a StarOS context.
Manages the keepalives to a CSS server within the specific VPN context.
Fetches the CSS related information for a subscriber
If a CSS server goes down, the cssmgr task reprograms the NPUs to by-pass
the service or redistribute the data among the rest of the servers in the
service.
Spawns daughter card managers during system initialization and monitors
daughter card managers during system steady state execution. It also spawns
daughter card managers whenever a daughter card manager task fails.
Responsible for managing IPSec Security Associations for AH- and
ESP-based sessions.
Interfaces with the on-board hardware accelerated cryptographic chip which
executes cryptographic algorithms associated with the given IPSec Security
Associations.
Started automatically on each CPU by SITPARENT.
Coordinates establishment of locally terminated TCP, SCTP, and UDP
connections on behalf of multi-instanced tasks such as Diameter endpoints
among sessmgr tasks.
Centralizes access to many of the system device drivers. It also performs
temperature and voltage monitoring.
Controls and manages the drive array spanning the management cards.
