This is sent by the server when it needs to migrate the client.

The client should cease transmitting SNACs and generate a OSERVICE__PAUSE_ACK SNAC to acknowledge it is ready. If the client ignores the PAUSE it will be kicked off after a short time period.

See more information about client migration.

SNAC Data

This SNAC has no fields and is always empty.

From Aleksandr Shutko: SNAC(01,0B) OSERVICE__PAUSE_REQ


This is the first SNAC in client migration sequence. See also known families list. Client should ack pause command with SNAC(01,0C) and stop send packets until it receive server resume SNAC(01,0D), or migration notice SNAC(01,12). Migration sequence used to redirect client to new BOS server during current BOS shutdown. Families array is optional.

OSERVICE SNACs

SNAC List
Subgroup Origin Name
0x0001 Any OSERVICE__ERR
This is the error SNAC for the OSERVICE foodgroup.
0x0002 Client OSERVICE__CLIENT_ONLINE
This message is sent by the client once it has initialized the host state (set preferences, Buddy Lists, locate information, capabilities) and is ready to be announced as being online by the host.
0x0003 Host OSERVICE__HOST_ONLINE
This is the very first SNAC sent from the host to the client after the FLAP signon frames are sent. It contains an array of all of the foodgroups the service supports.
0x0004 Client OSERVICE__SERVICE_REQUEST
This SNAC requests that the specified service (foodgroup) be provided to it in a way further specified by qualifying parameters.
0x0005 Host OSERVICE__SERVICE_RESPONSE
This SNAC contains information about connecting to the new server. It is the response from the server to a service request.
0x0006 Client OSERVICE__RATE_PARAMS_QUERY
This SNAC is sent by the client to query for the current rate limit parameters.
0x0007 Host OSERVICE__RATE_PARAMS_REPLY
Contains response to the OSERVICE__RATE_PARAMS_QUERY.
0x0008 Client OSERVICE__RATE_PARAMS_SUB_ADD
Subscribe to any rate parameter changes among the specified class IDs. If there was no prior subscription for a given class ID, an immediate notification will be queued.
0x0009 Client OSERVICE__RATE_DEL_PARAM_SUB
Cancels any rate parameter subscriptions for the specified class IDs.
0x000A Host OSERVICE__RATE_PARAM_CHANGE
This contains an array of class rate parameters that have changed since last query or notification.
0x000B Host OSERVICE__PAUSE_REQ
This is sent by the server when it needs to migrate the client.
0x000C Client OSERVICE__PAUSE_ACK
This is sent by the client to acknowledge the receipt and processing of a OSERVICE__PAUSE_REQ SNAC request.
0x000D Host OSERVICE__RESUME
In certain situations the server may abort a migration after having told the client to PAUSE.
0x000E Client OSERVICE__USER_INFO_QUERY
This is a query to find out one's current info. The server will send a OSERVICE__USER_INFO_UPDATE.
0x000F Host OSERVICE__USER_INFO_UPDATE
This SNAC is sent by the server whenever significant parts of a user's info change.
0x0010 Host OSERVICE__EVIL_NOTIFICATION
This is a notice that the user's evil level has changed.
0x0011 Client OSERVICE__IDLE_NOTIFICATION
This SNAC is sent by the client to inform the server of the user's idle state.
0x0012 Host OSERVICE__MIGRATE_GROUPS
This SNAC commands the client to reconnect to the server specified by the included OSERVICE__TLV_TAGS_RECONNECT_HERE TLV.
0x0013 Host OSERVICE__MOTD

0x0018 Host OSERVICE__HOST_VERSIONS
The host responds to OSERVICE__CLIENT_VERSIONS with its foodgroup version list so that the client knows what this host provides and its capabilities.
