Abstract

Growth of a distributed communication system is facilitated through dynamic addition of routing elements. A new routing element may be added to a network of routing elements by first establishing a connection between the new routing element and an existing routing element in the network. The connection may be either wireless or wireline. At least one address is assigned to the new routing element. Each assigned address comes from a pool of addresses maintained at the existing routing element. At least one pool of addresses is issued to the new routing element, permitting the new routing element to dynamically add yet another new routing element to the network of routing elements.

Claims

1. A method of dynamically adding a routing element to a distributed communications network comprising:

establishing an ATM virtual connection with an existing distribution point already part of the communications network;

requesting an ATM end user address from the existing distribution point;

obtaining an ATM end user address from the existing distribution point, the ATM end user address allocated from a pool of ATM end user addresses in the existing distribution point;

requesting an IP address from the existing distribution point;

obtaining an IP address from the existing distribution point, the IP address allocated from a pool of IP addresses in the existing distribution point;

requesting a pool of ATM end user addresses from an address server;

receiving a pool of ATM end user addresses from the address server;

requesting a pool of IP addresses from the address server; and

receiving a pool of IP addresses from the address server;

whereby an ATM end user address from the pool of ATM end user addresses and an IP address from the pool of IP addresses are assigned to a new routing element requesting to be added to the communications network.

2. A method of dynamically adding a routing element as in claim 1 wherein the routing element is a distribution point.

3. A method of dynamically adding a routing clement as in claim 2 further comprising:

forming a peer relationship with the existing distribution point at the data link layer for voice communication; and

forming a peer relationship with the existing distribution point at the network layer for data communication.

4. A method of dynamically adding a routing element as in claim 1 wherein the routing element is an access point interconnecting user communication devices with a distribution point.

5. A method of dynamically adding a routing element as in claim 4 wherein the access point is a local radio access point serving a plurality of packet radios.

6. A method of dynamically adding a routing element as in claim 4 further comprising:

forming a client relationship at the data link layer with the existing distribution point, the existing distribution point functioning as a server for voice communication; and

forming a client relationship at the network layer with the existing distribution point, the existing distribution point functioning as a server for data communication.

7. A method of dynamically adding a routing element as in claim 6 further comprising:

adding at least one access point as a client;

forming a peer relationship with communicating existing distribution points at the data link layer for voice communication; and

forming a peer relationship with communicating existing distribution points at the network layer for data communication.

8. A communications network for distributing packetized information comprising:

a supervisor operative to supply a plurality of pools of ATM end user addresses and a plurality of pools of IP addresses;

a plurality of access points, each access point operative to transmit packets to and receive packets from at least one subscriber unit; and

a plurality of distribution points, the access points and distribution points forming a network, each distribution point in communication with at least one other distribution point and with the supervisor, each access point in communication with at least one distribution point, each distribution point operative to

(a) obtain a pool of ATM end user addresses from the supervisor,

(b) obtain a pool of IP addresses from the supervisor,

(c) receive a request from a new network element to join the network,

(d) provide the new network element with an ATM end user address from the pool of ATM end user addresses, and

(e) provide the new network element with an IP address from the pool of IT addresses.

9. A communications network as in claim 8 wherein the new network element is a new distribution point.

10. A communications network as in claim 9 wherein the new distribution point forms a peer-to-peer relationship with the existing distribution point at the data link layer for voice communication and forms a peer-to-peer relationship with the existing distribution point at the network layer for data communication.

11. A communications network as in claim 8 wherein at least one distribution point is operative to function as an access point.

12. A communications network as in claim 8 wherein the new network element is a new access point.

13. A communications network as in claim 12 wherein the new access point forms a client relationship with the existing distribution point as a server at the data lint layer and the new access point forms a client relationship with the existing distribution point as a server at the network layer.

14. A communications network as in claim 12 wherein at least one access point is a local radio access point in wireless communication with at least one subscriber unit.

15. A communications network as in claim 12 wherein at least one access point is in wireline communication with at least one subscriber unit.

16. A communication network as in claim 12 wherein at least one access point is in wireless communication with at least one subscriber unit.

17. A communications network as in claim 12 wherein at least one access point is operative to function as a distribution point.

18. A communication network as in claim 8 wherein each distribution point is further operative to:

determine that the new network element is no longer joined to the network;

recover the ATM end user address provided from the pool of ATM end user addresses; and

recover the IP address provided from the pool of IP addresses.
