Abstract

The invention discloses an information switch, which comprises a management system, a core switching system and an information routing system. The core switching system at least comprises an information bus, a switching module and a switching management module. The information bus comprises an access bus (D-Bus) for connecting with device access gateways, a service bus (S-Bus) for connecting with service gateways, a management bus (M-bus) for connecting with the management system, and a routing bus (R-Bus) for connecting with the information routing system. The management system and the information routing system are connected with core switching via the information bus to perform, respectively, system management and routing management.

Claims

1. An information switch for implementing information switching matches comprising:

a management system; and

a core switching system;

wherein the core switching system comprises an information bus which is an interface between the information switch and peripherals, a switching module, and a switching management module, which are used for implementing the switching of a unique format information packet, said unique format information packet comprising an i-SML (information-service mark language) format information packet, wherein the header of the i-SML format information packet comprises a source information address, a destination information address, an information type and an information sequence number;

wherein the management system is connected with the core switching system via the information bus to perform system management; and

wherein the information bus is comprised of an information input/output interface and a data communication channel, and the information bus is further comprised of an access bus connecting with an external device access gateway, a service bus connecting with an external service gateway, and a management bus connecting with the management system.

2. The information switch according to claim 1, further comprising an information routing system for routing management.

3. The information switch according to claim 2, wherein the information bus is comprised of an information input/output interface;

and a data communication channel.

4. The information switch of claim 3, wherein the information bus is divided into an access bus connecting with external device access gateways;

a service bus connecting with external service gateways;

a management bus connecting with the management system; and

a routing bus connecting with the information routing system.

5. The information switch according to claim 2, wherein the information routing system is comprised of:

a remote communication module connecting with remote platform; and

a routing table storing routing information.

6. The information switch according to claim 1, wherein the switching management module is comprised of:

a switching module manager that manages the whole core switching system;

a switching module monitor that monitors and controls the core switching system;

a session manager that manages session type information switching; and

a security manager that controls security of the core switching system.

7. The information switch according to claim 1, wherein the switching module is comprised of a general control module;

and a queued access module.

8. The information switch according to claim 7, wherein the switching management module is further comprised of:

an addressing module;

a system monitoring module; and

an addressing table;

wherein the general control module gets a request from the queued access module, gets a destination service name by unpacking packet head data, gets corresponding destination physical address from the addressing module, and sets the request to the queued access module;

the queued access module accesses data packets in the queue;

the addressing module gets an idlest destination physical address according to destination logic or service address; and

the system monitor module monitors every client state and stores the state data to the addressing table.

9. The information switch according to claim 1, further comprising a plurality of switching modules, with each switching module having a connection to another switching module to form a switching cluster, and where the connections between the switching modules deploy load balancing technology by adding a front-end processor, or implemented by an internal high speed channel of the switching module.

10. The information switch according to claim 1, wherein the management system comprises a certificate authentication service;

a service manager;

a billing manager;

a user manager;

an access manager; and

a monitor.
