A method for spooling diameter transactions is provided. The method comprises receiving from a Diameter client a Diameter request message; determining based in part on a type of the received request message if the received request message should be spooled; determining if a current transaction rate exceeds a predefined spooling threshold, if the received request message should be spooled; and queuing the received request message if the current transaction rate exceeds the spooling threshold.

Method and system for spooling diameter transactions

A mechanism for achieving resiliency and load balancing for SIP application services and, in particular, in geographic distributed sites. A method performs a distribution of SIP requests among SIP servers, where at least two sites with a load balancer in each site is configured. The method includes receiving a SIP request by a first load balancer in a first site; determining whether the SIP request should be redirected to a second site; and redirecting the SIP request to an address of a second load balancer in the second site. The invention also includes a SIP proxy including a receiving unit receiving SIP requests; a load balancing unit distributing SIP requests between SIP entities; and a health monitoring unit verifying availability of the SIP entities. The SIP proxy may further be configured with a proximity measuring unit determining a proximity to a SIP entity.

Geographic resiliency and load balancing for SIP application services

A system, method and device for providing connection resiliency. The method including maintaining, by a first proxy, a TCP connection with a TCP client and a TCP connection with a TCP server through one or more TCP networks; maintaining information of both TCP connections by a forwarding component between the TCP networks and the first proxy; establishing, by the forwarding component, a new TCP connection with a second proxy for each of the TCP connections maintained by the first proxy; and forwarding data, to and from both the client and the server, to and from the second proxy without disconnection of the TCP connections of the TCP client and TCP server.
