Abstract
Abstract An improvement in the Open Systems Interconnection model in which Service Access Points can be established directly between peer entities in the same layer of a protocol stack. This direct seamless peer-to-peer communication is vastly superior to the use of a higher level relay function to set up and manage the communication path. In particular, setup messages are exchanged between the peer entities and a higher layer to create the Service Access Point between the peer entities. The setup and management capabilities are contained in each of the peer entities and hence no relay function is required after the peer Service Access Point, substantially speeding up the communication and reducing the management overhead.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
229 words
A data transmission system having a layered communications architecture in which a service user entity in one layer of a node of said system secures services from a service provider entity in an adjacent lower level layer of said node by means of service access points through which information blocks are routed between said service user entity and said service provider entity, said system comprising: a peer service access point for connecting any two peer entities in the same layer of said node for direct, seamless peer-to-peer communications of said information blocks between said any two entities, and means in each of said any two peer entities for setting up and maintaining communications between said any two peer entities via the peer service access point, said means for setting up and maintaining communications further comprising: a directory services entity responsive to a request from a first one of the peer entities for identifying an address associated with a second one of the peer entities, and a directory services entity responsive to a request from a first one of the peer entities for identifying an address associated with a second one of the peer entities, and means responsive to the address identification from the directory services entity for activating the peer service access point between said first one of the peer entities and said second one of the peer entities.
Claim 2
Dependent Claim
229 words
A data transmission system having a layered communications architecture in which a service user entity in one layer of a node of said system secures services from a service provider entity in an adjacent lower level layer of said node by means of service access points through which information blocks are routed between said service user entity and said service provider entity, said system comprising: a peer service access point for connecting any two peer entities in the same layer of said node for direct, seamless peer-to-peer communications of said information blocks between said any two entities, and means in each of said any two peer entities for setting up and maintaining communications between said any two peer entities via the peer service access point, said means for setting up and maintaining communications further comprising: a directory services entity responsive to a request from a first one of the peer entities for identifying an address associated with a second one of the peer entities, and a directory services entity responsive to a request from a first one of the peer entities for identifying an address associated with a second one of the peer entities, and means responsive to the address identification from the directory services entity for activating the peer service access point between said first one of the peer entities and said second one of the peer entities.
Claim 3
Dependent Claim
21 words
The data transmission system according to claim 1 wherein said layered communications architecture conforms to the Open Systems Interconnection (OSI) model.
Claim 4
Dependent Claim
21 words
The data transmission system according to claim 1 wherein said layered communications architecture conforms to the Systems Network Architecture (SNA) model.
Claim 5
Dependent Claim
22 words
The data transmission system according to claim 1 further comprising means for interchanging call setup messages between said any two peer entities.
Claim 6
Dependent Claim
51 words
The data transmission system according to claim 1 further comprising a control block associated with each of said peer service access points for storing the identification of that peer service access point and for storing the identification of the two peer entities with which that peer service access point is associated.
Claim 7
Dependent Claim
45 words
The data transmission system according to claim 1 wherein one of said two peer entities first requested to provide peer-to-peer communications services is designated as said service user entity and the other one of said two peer entities is designated as said service provider entity.
Claim 8
Dependent Claim
192 words
In a data transmission system having a layered communications architecture in which a service user entity in one layer of a node of said system secures services from a service entity in an adjacent lower level layer of said node by means of service access points through which information blocks are routed between said service user entity and said service provider entity, a method comprising the steps of: establishing a peer service access point for connecting any two peer entities in the same layer of said node for direct, seamless peer-to-peer communications of said information blocks between said any two entities, and setting up and maintaining communications between said any two peer entities by means included in each of said any two peer entities via the peer service access point, said step of setting up and maintaining communications further comprising: requesting by a first one of the peer entities from a directory services entity an address associated with a second one of the peer entities, and responsive to the address, activating the peer service access point between said first one of the peer entities and said second one of the peer entities.
Claim 9
Dependent Claim
192 words
In a data transmission system having a layered communications architecture in which a service user entity in one layer of a node of said system secures services from a service entity in an adjacent lower level layer of said node by means of service access points through which information blocks are routed between said service user entity and said service provider entity, a method comprising the steps of: establishing a peer service access point for connecting any two peer entities in the same layer of said node for direct, seamless peer-to-peer communications of said information blocks between said any two entities, and setting up and maintaining communications between said any two peer entities by means included in each of said any two peer entities via the peer service access point, said step of setting up and maintaining communications further comprising: requesting by a first one of the peer entities from a directory services entity an address associated with a second one of the peer entities, and responsive to the address, activating the peer service access point between said first one of the peer entities and said second one of the peer entities.

Dependent Claim
46 words
The method according to claim 7 further including the step of designating the one of said two peer entities first requested to provide peer-to-peer communications services as said service user entity and designating the other one of said two peer entities as said service provider entity.
