Abstract

Systems and methods for routing communications to a platform service are provided. A message including payload data is received. The information in the payload data of the message is examined in order to determine the type of message. The message is then relayed to an appropriate platform service based on the type of message. Some embodiments assign numbers to the packets that make up the message.

Claims

1. A method for routing a communication to a platform service, comprising:

receiving a first message in a first communication;

sending an acknowledgement message to a source of the first communication in reply to the first message;

receiving a second message in the first communication containing payload data;

analyzing payload data contained in the second message to identify a platform service associated with the payload data;

sending a first message in a second communication to the platform service;

receiving an acknowledgement of the first message from the platform service;

sending a second message in the second communication to the platform service, such that the second message in the second communication includes the payload data contained in the second message of the first communication;

receiving a reply to the second message in the second communication from the platform service; and

relaying the reply from the platform service to the source of the first communication.

2. The method of claim 1,

wherein the messages in the first communication are sequentially numbered and the messages in the second communication are sequentially numbered differently from the messages in the first communication;

and

further comprising

modifying the sequential numbering of the second message in the first communication to correspond with the sequential numbering of the second communication with the platform service; and

modifying the sequential numbering of the reply to the second message in the second communication to correspond with the sequential numbering of the first communication.

3. A method for routing a communication to a platform service, comprising:

receiving a communication comprising payload data;

determining a type of the communication based on at least information provided by the payload data; and

relaying the communication to a platform service based on at least the type of the communication.

4. The method of claim 3, further comprising receiving a reply from the platform service and relaying the reply to a source of the communication.

5. The method of claim 3, wherein the communication is transmitted using sequentially numbered packets.

6. A system for routing a communication to a platform service comprising:

an input module configured to receive a communication comprising payload data;

a processor configured to execute instructions stored in memory for determining a type of the communication based on at least information provided by the payload data; and

an output module configured to relay the communication to a platform service based on at least the type of the communication.

7. The system of claim 6, further comprising one or more platform services.
