A proxy directory server discovers the topology of distributed directory server immediately after starting up and before accepting client requests. Immediately after starting up, the proxy server executes queries to extract the structured data corresponding to directory distribution information from the distributed directory servers. Dynamic topology reconfiguration of the distributed directory is achieved by any dynamic configuration changes made to the topology information directly at the proxy during operation being propagated by means of directory update operations to the distributed directory servers.

The invention discloses a method and a system for allowing a mobile terminal to access a webpage, and belongs to the field of networks. According to method and the system for allowing the mobile terminal to access the webpage, when a user uses the mobile terminal to access the to-be-accessed webpage, and a webpage resource of the to-be-accessed webpage is not cached locally or the webpage resource of the to-be-accessed webpage is overdue, the webpage resource of the to-be-accessed webpage is acquired by a pre-established transit proxy server rather than directly from a webpage server; the webpage resource is wholly forwarded by the transit proxy server, so that the problem that an access failure due to a bad network environment between a certain webpage server and the mobile terminal in a certain time period can be solved; and the webpage is displayed directly when the webpage resource of the to-be-accessed webpage is cached and the webpage resource of the to-be-accessed webpage is not overdue, so that a success rate of using the mobile terminal to access the webpage is increased.

The invention discloses a seamless communication method for a substation and a dispatching master station. The method comprises the following steps: an IEC61850 proxy server is set up in the substation; the IEC61850 proxy server is added to a SCD model of the substation as an IED device; simulation proxy is carried out on the IED device in the substation through the IEC61850 proxy server; and the dispatching master station and the IED device in the substation communicate through the IEC61850 proxy server. Information transmission between the substation and the master station is improved, the problems of accuracy and reliability in information transmission are effectively solved, a high-quality and efficient basic information transmission and exchange way is provided for multiple application functions of an intelligent substation through seamless information and model transmission, and a good foundation platform is constructed for power grid dispatching and monitoring.

Provided are a system and method for transmitting and receiving Session Initiation Protocol (SIP) messages. The system includes user equipment (UE) including an SIP client configured to generate an SIP message, and an external transport configured to receive the SIP message from the SIP client, generate a packet by combining a tunneling header with the received SIP message, and transmit the generated packet to an SIP broker server, and the SIP broker server configured to receive the packet from the external transport in the UE, remove the tunneling header from the packet, and transmit the SIP message from which the tunneling header has been removed to a communication counterpart.

The invention discloses a compiling system, an electronic device and a readable medium. The system comprises a plurality of compiling devices and a shared cache server. The shared cache server is usedfor receiving a request for querying at least one cache middleware corresponding to the to-be-compiled object sent by the compiling devices; and based on the request, feeding back response information containing the cache middleware to the compiling devices. The compiling devices are used for obtaining a compiling object and sending a request for querying cache middleware to the shared cache server; and receiving response information which is fed back by the shared cache server and contains the cache middleware, and finishing the allocated compiling task by utilizing the cache middleware. According to the technical scheme, before the compiling proxy server carries out compiling, whether the compiled cache middleware corresponding to the to-be-compiled object exists in the shared cache server or not is searched for firstly, and if the corresponding cache middleware exists, repeated compiling is not needed; therefore, the compiling efficiency of the compiling system can be effectively improved.
