Abstract

Aspects of the invention provide a method and system for managing or coordinating data transmission in a Local Area Network (LAN) such that Quality of Service (QoS) concerns are met. A LAN resource manager (LRM) is provided for managing the LAN resources by providing solutions for providing users with several levels of QoS. Once the LRM admits a user at a certain QoS level, the level is assured within the LAN for as long as the user is in the LAN. A user may submit a request to transmit data to the LRM. The LRM may determine if time allocation is possible and allocate the time slots for data transmission. The LRM may send time slot allocation information to an Access Server in a LAN, which may inform the user of the time slot allocation and prepare a queue according to the slot allocation information.

Claims24

Dependent claims

A method for managing data transmission in a local area network comprising:

receiving a request for data transmission;
determining time frames, said time frames comprising time slots, said time slots comprising at least one dedicated traffic slot in an initial state characterized by being unreserved and not in use and being capable of converting to a first state characterized by being reserved and in use by a user if the dedicated traffic slot is in the initial state;
allocating the time slots to determine time slot allocation information;
and
providing the time slot allocation information for data transmission,
wherein the dedicated traffic slot converts to a second state characterized by being idle and reserved for the user if the dedicated traffic slot is in the first state and if data is not transmitted by the user in a first predetermined period of time,
the dedicated traffic slot converts to a third state characterized by being idle and for best effort use if the dedicated traffic slot is in the second state and if data is not transmitted by the user in a second predetermined period of time, and
the dedicated traffic slot converts to the initial state if the dedicated traffic slot is in the third state and if data is not transmitted by the user in a third predetermined period of time.

5 more elements

A method for managing data transmission in a local area network (LAN) comprising:

receiving at a LAN resource manager a request for data transmission, said LAN resource manager comprising a time allocation device for allocating time slots for data transmission among users in the LAN;
allocating the time slots to obtain time slot allocation information;
and
providing the time slot allocation information to an access server, said access server comprising a controller for providing the time slot allocation information to a user in the LAN,
wherein the time slots for data transmission comprise at least one each of an access server control slot, a common control slot, a best effort slot and a dedicated traffic slot.
