METHOD AND SYSTEM FOR GUARANTEED END-TO-END DATA FLOWS IN A LOCAL NETWORKING DOMAIN
A local manager in a local networking domain may configure, in conjunction with one or more switching devices, a plurality of network and/or switching devices to establish guaranteed end-to-end data flows in the local networking domain for servicing applications and/or processes running in the network devices. The network devices supporting or using guaranteed end-to-end data flows may determine data flow requirements for each serviced application, and may communicate the determined data flow requirements to switching devices supporting the local manager, for configuring the guaranteed end-to-end data flows. Data flow requirements may comprise bandwidth, quality of service (QoS), security, and/or service level agreement (SLA) related parameters. The network devices may allocate networking resources to guarantee the end-to-end data flow for each application running in each network device. Data flow routing tables maybe maintained and/or updated based on use of existing guaranteed end-to-end data flows.
1 . A method for communication, the method comprising:
in a switching device that provides switching services in a local networking domain that comprises a plurality of network devices:
receiving from at least a first network device of said plurality of network devices, data flow requirements for communicating data for each of a plurality of applications running on said first network device; and
configuring, by said switching device in conjunction with a local manager, said first network device and/or one or more remaining network devices from said plurality of network devices to maintain guaranteed end-to-end data flows for each of said plurality of applications based on said received data flow requirements.
2 . The method according to claim 1 , wherein said switching device comprises a blade switch or a top-of-rack (ToR) switch.
3 . The method according to claim 1 , wherein said data flow requirements comprise bandwidth, quality of service (QoS), security, and/or service level agreement (SLA) based parameters.
4 . The method according to claim 1 , wherein said local manager runs on said switching device.
5 . The method according to claim 1 , comprising maintaining, by said switching device in conjunction with said local manager, a routing table for storing information corresponding to said end-to-end data flows.
6 . The method according to claim 1 , comprising assigning, by said switching device in conjunction with said local manager, each of said guaranteed end-to-end data flows a unique identifier for routing and/or switching operations in said local networking domain.
7 . The method according to claim 1 , comprising assigning, by said switching device in conjunction with said local manager, each of said guaranteed end-to-end data flows a unique virtual local area network (VLAN) tag for routing and/or switching data in said first network device and/or in said one or more other network devices.
8 . The method according to claim 1 , comprising maintaining, by said switching device in conjunction with said local manager, servicing of said guaranteed end-to-end data flows during migration operations in said local networking domain.
9 . The method according to claim 1 , wherein said first network device and/or at least a portion of said one or more other network devices is operable to determine said data flow requirements for each application running in said network device.
10 . The method according to claim 1 , wherein said first network device and/or at least a portion of said one or more other network devices is operable to allocate networking resources to guarantee said end-to-end data flow for each of said plurality of applications.
11 . A system for communication, the system comprising:
one or more circuits and/or processors for use in a switching device that provides switching services in a local networking domain that comprises a plurality of network devices, said one or more circuits and/or processors are operable to:
receive from at least a first network device of said plurality of network devices, data flow requirements for communicating data for each of a plurality of applications running on said first network device; and
configure, by said switching device in conjunction with a local manager, said first network device and/or one or more remaining network devices from said plurality of network devices to maintain guaranteed end-to-end data flows for each of said plurality of applications based on said received data flow requirements.
12 . The system according to claim 11 , wherein said switching device comprises a blade switch or a top-of-rack (ToR) switch.
13 . The system according to claim 11 , wherein said data flow requirements comprise bandwidth, quality of service (QoS), security, and/or service level agreement (SLA) based parameters.
14 . The system according to claim 11 , wherein said local manager runs on said switching device.
15 . The system according to claim 11 , wherein said one or more circuits and/or processors are operable to maintain, by said switching device in conjunction with said local manager, a routing table for storing information corresponding to said end-to-end data flows.
16 . The system according to claim 11 , wherein said one or more circuits and/or processors are operable to assign, by said switching device in conjunction with said local manager, each of said guaranteed end-to-end data flows a unique identifier for routing and/or switching operations in said local networking domain.
17 . The system according to claim 11 , wherein said one or more circuits and/or processors are operable to assign, by said switching device in conjunction with said local manager, each of said guaranteed end-to-end data flows a unique virtual local area network (VLAN) tag for routing and/or switching data in said first network device and/or in said one or more other network devices.
18 . The system according to claim 11 , wherein said one or more circuits and/or processors are operable to maintain, by said switching device in conjunction with said local manager, servicing of said guaranteed end-to-end data flows during migration operations in said local networking domain.
19 . The system according to claim 11 , wherein said first network device and/or at least a portion of said one or more other network devices is operable to determine said data flow requirements for each application running in said network device.
20 . The system according to claim 11 , wherein said first network device and/or at least a portion of said one or more other network devices is operable to allocate networking resources to guarantee said end-to-end data flow for each of said plurality of applications.
