Abstract
A switching device and methods thereof are disclosed. One of the methods includes an arbitration process for communicating a data payload between interface modules. A first intra-chassis packet is sent by a source interface module to the target interface module. The first intra-chassis packet represents a request for permission to transmit a data payload to the target interface. A second intra-chassis packet is received at the source interface module from the target interface module indicating whether the request has been approved. If the request is approved, the source interface module sends a third intra-chassis packet comprising at least a portion of the data payload to the target interface module.
Claims20
A method, comprising:
- transmitting a first intra-chassis packet comprising first information representing a first authorization request to transmit a data payload to a second device;
- receiving a second intra-chassis packet comprising second information in response to transmitting the first intra-chassis packet;
- and
- transmitting a third intra-chassis packet in response to the second information representing approval of the first authorization request, the third intra-chassis packet comprising third information representing a first portion of the data payload.
A method, comprising:
- receiving a first intra-chassis packet comprising first information representing a first authorization request to transmit a first data payload to a second device;
- transmitting a second intra-chassis packet comprising second information in response to receiving the first intra-chassis packet;
- and
- receiving a third intra-chassis packet in response to the second information representing approval of the first authorization request, the third intra-chassis packet comprising third information representing a first portion of the first data payload.
A device, comprising:
- a first communication interface comprising:
- a first output configured to transmit a first intra-chassis packet comprising first information representing a first authorization request to transmit a data payload to a second device;
- a first input configured to receive a second intra-chassis packet comprising second information in response to transmitting the first intra-chassis packet;
- a second output configured to provide the second intra-chassis packet;
- and
- a second input;
- and
- a control module comprising:
- an input coupled to the second output of the first communication interface;
- and
- an output coupled to the second input of the first communication interface, the output to indicate to the first communication interface to transmit a third intra-chassis packet in response to the second information representing approval of the first authorization request, the third intra-chassis packet comprising third information representing a portion of the data payload.
