Abstract

A operating system creates a semantic-based platform or fabric that provides a service oriented network. The operating system assigns virtual addresses to services registered with the network. Messages for the services are sent by service requesters using their virtual addresses. The virtual address is then mapped to the actual address of the service provider, which is then sent to the intended service provider. The messages are processed according to an SOA stack, where messages can be routed at the virtual IP, transport, or message layer without the need to process the message at the IP layer. The web services can be classified into a service zone, with the zone exposed to a service requester as a single entity. The zone is an independent domain, with communication within the zone managed by a semantic-based switch in the switch fabric.

Claims

1. A network, comprising:

a first table comprising a list of web services registered with a semantic-based switch fabric;

a second table comprising a list of virtual addresses assigned to the web services; and

a plurality of semantic-based switches, wherein each semantic-based switch provides an end-to-end connection between service requesters and service providers utilizing the virtual addresses.

2. The network of claim 1, wherein a first switch receives a message from a service requester comprising a virtual address assigned to a web service, wherein the first switch performs a look-up in the second table to obtain an address of a service provider assigned to the virtual address, wherein the first switch sends the message to the service provider.

3. The network of claim 1, further comprising a third table comprising a list of unmapped virtual addresses.

4. The network of claim 3, wherein when a web service deregisters from the network, a virtual address assigned to the web service is listed in the third table.

5. The network of claim 1, wherein one of the plurality of semantic-based switches is assigned to be a gateway for a service requester.

6. The network of claim 5, wherein the assigning of the gateway comprises:

receiving an address resolution query from the service requester;

making an address resolution call; and

returning an address of the gateway to represent the network to the service requester.

7. The network of claim 1, wherein a plurality of web services are classified into a service zone, wherein the service zone is exposed to the service providers as a single entity.

8. The network of claim 7, wherein the service zone is an independent domain, wherein communication within the service zone is managed by one or more semantic-based switches.

9. The network of claim 1, further comprising a WS-Ping call for pinging one or more web services.

10. The network of claim 1, further comprising a WS-Tracert call for tracing a route between a service requester and a service provider.

11. The network of claim 1, further comprising a WS-SPF call for determining a shortest path first between a service requester and a service provider.

12. A method for providing a service in a network, comprising:

registering a web service with the network, wherein the web service is listed in a first table of registered web services;

assigning to the web service a virtual address, wherein the web service and its assigned virtual address are listed in a second table;

receiving a web service request from a service requester;

obtaining from the second table the virtual address assigned to the requested web service; and

sending the virtual address to the service requester, wherein the service requester can send a message to a switch using the virtual address.

13. The method of claim 12, further comprising:

receiving the message by a first switch, wherein the message comprises the virtual address;

obtaining from the second table an address for a service provider of the web service assigned to the virtual address in the message; and

sending the message to a second switch servicing the service provider.

14. The method of claim 12, further comprising:

deregistering the web service from the network; and

listing the virtual address assigned to the web service in a third table of unmapped virtual addresses.

15. The method of claim 12, further comprising:

assigning the switch to function as a gateway to the network for the service requester.

16. The method of claim 15, wherein the assigning comprises:

receiving an address resolution query from the service requester;

making an address resolution call; and

returning an address of the switch to the service requester.

17. The method of claim 12, further comprising:

classifying one or registered web services into a service zone, wherein the service zone is exposed to the service provider as a single entity.

18. The method of claim 17, wherein the service zone is an independent domain, wherein communication within the service zone is managed by one or more semantic-based switches.

19. The method of claim 12, further comprising:

issuing a WS-Ping call for pinging one or more web services.

20. The method of claim 12, further comprising:

issuing a WS-Tracert call for tracing a route between the service requester and a service provider.

21. The method of claim 12, further comprising:

issuing g WS-SPF call for determining a shortest path between the service requester and a service provider.

22. An operating system stack, comprising:

a physical and link layer;

an Internet protocol layer;

a virtual internet protocol layer overlaid on the Internet protocol layer, wherein virtual addresses are assigned to web services registered with a semantic-based switch fabric;

a transmission control protocol layer;

a transport protocol layer; and

a message protocol layer.

23. The stack of claim 22, further comprising:

a proxy or gateway layer for processing a message when a semantic-based switch in the semantic-based switch fabric functions as a gateway for a service requester or as a proxy for a service provider; and

a caching layer for caching network information for switching functionalities.

24. The stack of claim 22, wherein a message is routed with processing at the message protocol layer without a need to process at the IP layer.

25. The stack of claim 22, wherein a message is routed with processing at the transport protocol layer without a need to process at the IP layer.

26. The stack of claim 22, wherein a message is routed with processing at the virtual IP layer without a need to process at the IP layer.
