Problems solved by technology

[0006] The disadvantage of using sorted lists in DNS servers is that there is no guarantee that the original order will always be maintained when passing information from DNS server to DNS server
[0010] The problem with static pool handling is that the pool must be configured and updated at any node that can be affected by pool handling changes
[0011] Another problem with static and DNS-based pooling is that it cannot account for changes in the network without being reconfigured
However, in this scenario, adding / removing pool elements to / from the pool can become a frequent event, significantly affecting the configuration

Embodiment Construction

[0032]The following description sets forth specific details, such as specific embodiments, procedures, techniques, etc., for purposes of explanation and not limitation. In some instances, detailed descriptions of well-known methods, interfaces, circuits, and devices are omitted so as not to obscure the description with unnecessary detail. Additionally, individual blocks are shown in some of the drawings. It should be understood that the functions of these blocks may be implemented using individual hardware circuits, using software programs and data, in conjunction with a suitably programmed digital microprocessor or general purpose computer, using application specific integrated circuits, and / or using one or more digital signal processors.

[0033] refer here figure 1 , when a host 101 attaches to a fixed access network and requests service from an Access Edge (AE) or Service Edge (SE) node, the most appropriate AE 102 or SE 103 node to be used by the host is selected from th...

Abstract

A method and apparatus for selecting an edge node from a plurality of edge nodes in a fixed access communications network. A selection node receives from a host entity a request for a network service. The selection node then obtains, from at least one further network node, data relating to a plurality of edge nodes. On thebasis of the retrieved data, the selection node selects an edge node from the plurality of edge nodes, wherein the selected edge node provides a path between the host entity and the requested network service. The selection node then sends a response to the host entity, the response including information identifying the selected edge node.

Description

technical field [0001] The present invention relates to a method and a device used in a communication network, in particular to a method and a device for allocating pooled nodes to hosts in a fixed access network. Background technique [0002] The Internet and mobile communication networks such as Global System for Mobile Communications (GSM) and 3G use gateway nodes to allow hosts to access the communication network and to allow server nodes to provide services to the hosts. Edge nodes, such as access and service edge nodes, are frequently "pooled" in the network to allow load sharing and balancing among pool members, as well as to allow higher availability and to allow better resource utilization. Pools are traditionally configured statically, and static pool processing can also be based on Domain Name System (DNS). [0003] Statically configured pools are based on the idea of ​​statically preconfiguring information about edge nodes selectable for a given service. A sele...
