▄  VPC-VSM System Administration Guide, StarOS Release 19 

 

 

 

afio

 

ASR 5500 Fabric I/O 
Driver

 

Responsible for the direct configuration of the fabric chipset. afio supports non-messenger 
interprocess communication (IPC) with the local afmgr and with other local afio instances

 

connproxy

 

TCP/SCTP 
Connection proxy

 

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.

 

cspctrl

 

Card-Slot-Port 
Controller 

 

Manages physical chassis components.

 

cssctrl

 

Content Server 
Selection (CSS) 
Controller

 

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.

 

cssmgr

 

Content Server 
Selection (CSS) 
Manager

 

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.

 

dcardctrl

 

Daughter Card 
Controller  
[ASR 5x00 only] 

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. 

dcardmgr

 

Daughter Card 
Manager  
[ASR 5x00 only] 

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.

 

dhmgr

 

Distributed Host 
Manager 

 

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.

 

drvctrl

 

Driver Controller 

 

Centralizes access to many of the system device drivers. It also performs temperature and 
voltage monitoring. 

hdctrl

 

Hard Drive Controller 

 

Controls and manages the drive array spanning the management cards. 

hwctrl

 

Hardware Controller 

The hwctrl task has several timers that manage polling loops for hardware sensor readings, 
sensor threshold monitoring, and fan tray monitoring.

 

hwmgr

 

Hardware Manager 

The hwmgr task runs on all cards in the chassis to read local accessible hardware sensors 
and report them back to the hwctrl.

 

inetd

 

InterNET Service 

The subsystem responsible for starting most of the network services.
