TURN module (rfc5766)

ServerObserver

Observer interface that the application must implement to participate in server-side allocation management and authentication.

#include <icy/turn/server/server.h>

struct ServerObserver

Defined in src/turn/include/icy/turn/server/server.h:96

The observer is responsible for enforcing per-user allocation quotas and bandwidth limits. Implementations may perform authentication synchronously (returning Authorized/NotAuthorized immediately) or asynchronously (returning Authenticating and calling handleRequest() again later).

Public Methods

ReturnNameDescription
voidonServerAllocationCreated virtualCalled after a new allocation is successfully created.
voidonServerAllocationRemoved virtualCalled just before an allocation is destroyed (expired, deleted, or server stopped).
AuthenticationStateauthenticateRequest virtualAuthenticates an incoming STUN request using the long-term credential mechanism (RFC 5389 section 10.2). Return Authorized to proceed, NotAuthorized to reject with a 401, QuotaReached to reject with a 486, or Authenticating to defer until the result is available asynchronously.

onServerAllocationCreated

virtual

virtual void onServerAllocationCreated(Server * server, IAllocation * alloc)

Defined in src/turn/include/icy/turn/server/server.h:101

Called after a new allocation is successfully created.

Parameters

ParameterTypeDescription
serverServer *The server that owns the allocation.
allocIAllocation *The newly created allocation (lifetime managed by the server).

onServerAllocationRemoved

virtual

virtual void onServerAllocationRemoved(Server * server, IAllocation * alloc)

Defined in src/turn/include/icy/turn/server/server.h:106

Called just before an allocation is destroyed (expired, deleted, or server stopped).

Parameters

ParameterTypeDescription
serverServer *The server that owned the allocation.

authenticateRequest

virtual

virtual AuthenticationState authenticateRequest(Server * server, Request & request)

Defined in src/turn/include/icy/turn/server/server.h:115

Authenticates an incoming STUN request using the long-term credential mechanism (RFC 5389 section 10.2). Return Authorized to proceed, NotAuthorized to reject with a 401, QuotaReached to reject with a 486, or Authenticating to defer until the result is available asynchronously.

Returns

An AuthenticationState indicating how to proceed.

Parameters
