Switching device with asymmetric port speeds
First Claim
Patent Images
1. A switching device comprising:
- a plurality of ports to transmit data to and receive data from external sources, wherein the ports operate at asymmetric speeds;
a switching matrix to provide selective connectivity between the ports;
a plurality of channels to connect the ports to the switching matrix, wherein number of channels associated with each port is determined by speed of the port; and
a scheduler to select connectivity between the ports and to configure the switching matrix accordingly, wherein said scheduler connects all the channels associated with a first port to a subset of the channels associated with a second port, if the first port is operating at a lower speed than the second port.

Abstract
In general, in one aspect, the disclosure describes a switching device that includes a plurality of ports. The ports operate at asymmetric speeds. The apparatus also includes a switching matrix to provide selective connectivity between the ports. The apparatus further includes a plurality of channels to connect the ports to the switching matrix. The number of channels associated with each port is determined by speed of the port.

10. A method comprising:
-
selecting connection paths between a plurality of ports, wherein the ports are capable of operating at different speeds from one another, wherein the ports are connected to a switching matrix via a plurality of channels, and wherein number of channels associated with a port is determined by speed of the port; and configuring the switch matrix, in response to said selecting, to connect the channels associated with an incoming port to the channels associate with a corresponding outgoing port, wherein said configuring includes connecting all the channels associated with a first port to a subset of the channels associated with a second port, if the first port is operating at a lower speed than the second port. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A store and forward device comprising:
-
a plurality of Ethernet cards to receive data from and transmit data to external sources, wherein a first one of the plurality of Ethernet cards is capable of operating at a first speed and a second one of the plurality of Ethernet cards is capable of operating at a second speed that is different than the first speed; a switching matrix to provide selective connectivity between the Ethernet cards; a backplane consisting of a plurality of channels to connect the plurality of Ethernet cards to the switching matrix, wherein number of channels associated with an Ethernet card is based on speed of the Ethernet card; and a scheduler to select connectivity between Ethernet cards and to configure the switching matrix accordingly, wherein said scheduler connects all the channels associated with a first Ethernet card to a subset of the channels associated with a second Ethernet card, if the first Ethernet card is operating at a lower speed than the second Ethernet card. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)
