VAN SDN Manager overview

Virtual Application Networking (VAN) is a network solution on virtualization, automation, and software-defined networks.

SDN is a new networking architecture that separates the control plane from the data plane of a network device. SDN is mainly implemented by using the OpenFlow technology.

SDNM is an IMC service component used to manage OpenFlow-based SDN.

OpenFlow

OpenFlow keeps the flow-based forwarding function. A non-OpenFlow switch matches five or seven tuples only, while an OpenFlow switch can match more tuples, including VLAN tag, MPLS tag, PBB tag, and so on.

To improve network resource usage, use the controller to create multiple OpenFlow instances on a single OpenFlow switch. Each instance operates as an independent virtual OpenFlow device. By creating and deploying flow entries to one or more virtual OpenFlow devices, the controller directly controls the packet forwarding to set up different forwarding paths for different network users.

The OpenFlow specification defines contents of the OpenFlow technology, including:

·     OpenFlow switch components.

·     OpenFlow ports.

·     OpenFlow tables.

·     OpenFlow channel.

·     OpenFlow protocol.

The OpenFlow specification includes multiple versions; SDNM uses OpenFlow 1.3.1.

OpenFlow network

OpenFlow switch

An OpenFlow switch may be a physical switch or a virtual switch (vSwitch) that supports the OpenFlow protocol.

OpenFlow switches consist of two types:

·     OpenFlow-only, which supports only OpenFlow operation.

·     OpenFlow-hybrid, which supports both OpenFlow operation and Ethernet switching operations.

Controller

A controller is typically a dedicated Linux server on which controller applications are deployed. The controller controls various resources in the OpenFlow network and provides APIs for applications to control packets forwarding.

OpenFlow network

In an OpenFlow network, as shown in Figure 1, the controller directly controls the packet forwarding for OpenFlow switches. The control packets (defined by the OpenFlow protocol) between OpenFlow switches and controller are transmitted through a secure channel.

The controller provides centralized control on the data plane of OpenFlow switches through the OpenFlow protocol.

An OpenFlow switch can communicate with multiple controllers. The OpenFlow channel between the OpenFlow switch and each controller can have only one main connection.

An OpenFlow switch communicates with the controller through a secure channel; the connection must use TCP or SSL.

An OpenFlow switch forwards packets between endpoints and servers according forwarding rules deployed by the controller.

Figure 1 OpenFlow Network

Figure-1.png

 

OpenFlow instance

For OpenFlow switches that support multiple OpenFlow instances, each OpenFlow instance is considered a separate logical OpenFlow switch and is identified by a unique DataPath ID (DPID).

For OpenFlow switches that do not support multiple OpenFlow instances, such as vSwitches, the OpenFlow switch itself is considered an OpenFlow instance and is identified by a unique DPID.

A DPID is 64 bits in length. By default, the lower 48-bits are for the MAC address of the network bridge of the device to which the OpenFlow instance belongs; the upper 16-bits are vendor-defined.

OpenFlow table

Each OpenFlow instance includes the following elements:

·     One or more flow tables.

·     One group table.

·     One meter table.

For more information about the flow table, pipeline, meter, and group, see "Managing OpenFlow."

Flow table

Flow tables in an OpenFlow instance are identified by flow table IDs. An OpenFlow switch matches packets against one or more flow tables in the pipeline. Each flow table includes one or more flow entries.

A flow entry consists of the following fields:

Figure 2 Flow entry

Figure-2.png

 

For more information about the flow entry referenced in Figure 2, see version 1.3.1 of the Open Networking Foundation "OpenFlow Switch Specification" located at:

https://www.opennetworking.org/images/stories/downloads/sdn-resources/onf-specifications/openflow/openflow-spec-v1.3.1.pdf

The field descriptions are as follows:

·     Match Fields—Match fields contained in a flow entry.

·     Priority—Priority of a flow entry. The larger this number, the higher the priority.

·     CountersCounter for a flow entry.

·     Instructions—A set of instructions contained in a flow entry. When a packet matches the flow entry, the instructions are executed.

·     Timeouts—Timeout time for a flow entry.

·     Cookie—Cookie for a flow entry.

Group table

Groups are used for multicasting and broadcasting. An OpenFlow instance has only one group table. The group table has zero or more group entries. Any flow entry can add an action that points to a group and to its instructions set, and executes the action bucket according to the group type.

A group entry consists of the following fields:

Figure 3 Group entry

Figure-3.png

 

For more information about the group entry referenced in Figure 3, see version 1.3.1 of the Open Networking Foundation "OpenFlow Switch Specification" located at:

https://www.opennetworking.org/images/stories/downloads/sdn-resources/onf-specifications/openflow/openflow-spec-v1.3.1.pdf

The field descriptions are as follows:

·     Group ID—A unique identifier for a group.

·     Group Type—Type of the group:

?     All

?     Indirect

?     Select

?     Fast Failover

·     Counters—Counter for a group.

·     Action Buckets—An ordered action bucket list for a group. Each action bucket contains a set of actions to be executed along with associated parameters. Algorithms performed for an action bucket vary with group types.

Meter table

Meters are used for OpenFlow to support Quality of Service (QoS). An OpenFlow instance has only one meter table. A meter table has zero or more meter entries. Any flow entry can specify a meter in its instructions set; the meter measures and controls the rates of flows assigned to it.

A meter entry consists of the following fields:

Figure 4 Meter entry

Figure-4.png

 

For more information about the meter entry referenced in Figure 4, see version 1.3.1 of the Open Networking Foundation "OpenFlow Switch Specification" located at:

https://www.opennetworking.org/images/stories/downloads/sdn-resources/onf-specifications/openflow/openflow-spec-v1.3.1.pdf

The field descriptions are as follows:

·     Meter ID—A unique identifier for a meter.

·     Meter Bands—An unordered meter band list. Each meter band specifies a flow rate and a processing mode.

·     Counters—Counter for a meter.

Managing OpenFlow

OpenFlow uses a flow-based forwarding method. SDNM manages the elements involved in the OpenFlow forwarding process, including flow tables, flow entries, groups, meters, and service flows.

Managing flow tables

In an OpenFlow network, each packet is processed by the OpenFlow pipeline of every OpenFlow switch that the packet passes through. Each OpenFlow instance maintains a set of flow tables, which are uniquely identified by their table IDs. A flow table contains one or multiple flow entries for matching and processing packets.

To better understand OpenFlow forwarding rules, view and query flow tables by using the flow management module of SDNM.

Pipeline processing

As shown in Figure 21, the pipeline of every OpenFlow switch can contain multiple flow tables. An OpenFlow switch uses the flow entries in the flow tables to match and process received packets.

Figure 21 OpenFlow pipeline of an OpenFlow switch

image2.emf

 

For more information about the OpenFlow Switch diagram, referenced in Figure 21, see version 1.3.1 of the Open Networking Foundation "OpenFlow Switch Specification" located at:

https://www.opennetworking.org/images/stories/downloads/sdn-resources/onf-specifications/openflow/openflow-spec-v1.3.1.pdf

OpenFlow pipeline processing can only go forward. Flow tables in the OpenFlow switch are sequentially numbered starting at 0. When a packet arrives at the switch, the pipeline starts packet matching at table 0. The packet is first matched against the flow entries in table 0. Then the packet is forwarded to another flow table based on the match result of table 0. A flow entry can pass the packet only to a flow table whose ID is larger than its table ID.

The OpenFlow pipeline defines how each flow entry acts on a packet. If a packet does not match any flow entry, a table miss occurs. A table-miss flow entry defines how to process an unmatched packet.

As shown in Figure 22, the OpenFlow pipeline processes a packet by following these steps:

1.     Match the packet against the flow entries of a flow table in descending order of priority. The greater the priority value, the higher the priority.

2.     Execute the instruction set if the packet is matched:

a.     Modify the packet and update its match fields by using the Apply-Actions instruction.

b.     Update the action set by using the Clear-Actions and Write-Actions instructions.

c.     Update metadata by using the Write-Metadata instruction.

d.     Send the matched packet and action set to the next flow table by using the Goto-Table instruction.

 

 

NOTE:

The flow entries in the last flow table do not contain the Goto-Table instruction.

 

3.     Execute the action set of the packet when pipeline processing stops.

Figure 22 OpenFlow packet matching process

For more information about the OpenFlow packet matching process, referenced in Figure 22, see version 1.3.1 of the Open Networking Foundation "OpenFlow Switch Specification" located at:

Managing flow entries

OpenFlow uses flow entries to match and process packets. Figure 23 shows the main components of a flow entry.

Figure 23 Main flow entry components

Figure-2.png

 

For more information about the flow entry components, referenced in Figure 23, see version 1.3.1 of the Open Networking Foundation "OpenFlow Switch Specification" located at:

https://www.opennetworking.org/images/stories/downloads/sdn-resources/onf-specifications/openflow/openflow-spec-v1.3.1.pdf

In a flow table, a flow entry is uniquely identified by its match fields and priority. A table-miss flow entry's match fields are omitted, and its priority is 0. In a flow table, the fields of a packet are matched against the match fields of flow entries in order of priority. If the packet matches a flow entry, the instruction set of the flow entry is executed on the packet.

The flow entry management module of SDNM views, queries, adds, modifies, and deletes flow entries, which helps when making OpenFlow forwarding rules.

Match fields

Match fields of a flow entry are used in packet matching. If a packet matches a flow entry, the instruction set of the flow entry is executed on the packet. Match fields originate from packet fields, including the input port, physical input port, inter-table metadata, Layer 2 header, Layer 3 header, and Layer 4 header fields. Table 5 shows detailed information about each match field.

Configuring the instruction set for a flow entry

The instruction set of a flow entry defines the actions to be executed on a matched packet. It can contain multiple types of instructions, but each instruction type can contain only one instruction. When a packet matches the flow entry, the instruction set is executed on the packet. The instructions affect the contents and action set of the packet, and the pipeline processing flow.

Table 6 Instructions

Instruction

Function

Meter

Forward the packet to a specified meter for processing.

Apply-Actions

Execute specified actions in the action list.

Clear-Actions

Clear the action set of the packet.

Write-Actions

Add specified actions to the action set of the packet.

Write-Metadata

Write metadata into the metadata field of the packet.

Goto-Table

Forward the packet to a specified flow table for processing.

 

To configure the instruction set for a flow entry:

1.     Access the Add OF Entry page.

2.     Configure the following instructions. These instructions are in descending order of priority:

?     Meter—Select Meter, and enter a meter ID.

?     Apply-Actions—Select Apply-Actions. Click Add for this instruction, and specify an action. For more information about the configuration procedure, see "Configuring actions." You can add multiple actions for each action type. Information about the action is displayed after the action is added.

?     Clear-Actions—Select Clear-Actions.

?     Write-Actions—Select Write-Actions. Click Add for this instruction, and specify an action. For more information about the configuration procedure, see "Configuring actions." Only one action can be added for each action type. Information of the action is displayed after the action is added. The added action overrides the original action, if the action of the specified type already exists.

?     Write-Metadata—Select Write-Metadata, and enter metadata.

?     Goto-Table—Select Goto-Table, and enter a flow table ID. The table ID must be larger than the table ID of the flow entry. The flow entries of the last flow table do not have the Goto-Table instruction.

Configuring actions

The Apply-Actions instruction specifies a sequence of actions to be immediately executed on a packet. The action set of the packet is not affected when the action list is executed. The Write-Actions instruction adds actions to the action set of a packet.

Action set

An action set is bound to each packet. Initially, the action set does not contain any actions, but as the packet is processed by flow tables, actions accumulate in the action set. A flow entry can use the Write-Actions or Clear-Actions instruction to modify or clear the action set. The action set does not immediately change contents of the packet after the packet is processed by a flow entry. After the packet is processed by a flow entry that does not contain the Goto-Table instruction, the pipeline processing ends. Then the action set of the packet is executed.

In an action set, each action type includes only one action. If the action set contains groups, actions in each group are executed in order.

The actions in an action set or group are executed in the following order:

1.     Copy TTL Inwards

2.     Pop VLAN/MPLS/PBB Tag

3.     Push MPLS Tag

4.     Push PBB Tag

5.     Push VLAN Tag

6.     Copy TTL Outwards

7.     Decrement MPLS/IP TTL

8.     Set MPLS TTL/IP TTL/Field

9.     Set Queue

10.     Group

11.     Output

Action list

The Apply-Actions instruction modifies a packet by applying an action list to the packet. The actions in an action list are the same as those in an action set, except that the actions in the action list immediately modify the contents of a packet. Effects of the actions are cumulative. The actions are executed in the order specified by the action list.

Table 7 shows the actions supported by an OpenFlow switch.

Table 7 Actions

Managing groups

The ability of a flow entry to point to a group enables OpenFlow devices to apply additional forwarding methods. A group table consists of group entries. An OpenFlow switch can have only one group table. Figure 24 shows the components of a group entry.

Figure 24 Group entry components

Figure-3.png

 

For more information about the group entry components, referenced in Figure 24, see version 1.3.1 of the Open Networking Foundation "OpenFlow Switch Specification" located at:

https://www.opennetworking.org/images/stories/downloads/sdn-resources/onf-specifications/openflow/openflow-spec-v1.3.1.pdf

Each group includes multiple buckets where each action bucket contains a set of actions to execute and associated parameters. The group type determines which action buckets are to be executed when packets match a group.

The group management module of SDNM views, queries, adds, modifies, and deletes groups, which helps create extra OpenFlow forwarding rules.

Network virtualization

To improve network resource usage for different network users, SDNM provides the network virtualization function. This function virtualizes the physical OpenFlow network in a horizontal view. For example, it can be used to create multiple OpenFlow instances on a single OpenFlow switch. Each instance operates as an independent virtual OpenFlow device. Tenants can use one or more virtual OpenFlow devices to build their respective OpenFlow logical networks.

With network virtualization, the following functions can be implemented:

·     Manage virtual OpenFlow devices.

·     Manage the tenant's logical network.

Managing virtual OpenFlow devices

SDNM provides an OpenFlow device virtualization module for operators to add virtual OpenFlow devices based on OpenFlow switches and to centrally manage the virtual devices.

Viewing the virtual OpenFlow device list

Virtual OpenFlow devices in the list come from:

·     Virtual OpenFlow devices that are synchronized from the controllers in SDNM.

·     OpenFlow instances that are created by SDNM operators.

A virtual OpenFlow device takes the DPID as its device label if it is synchronized from a controller.

To view the virtual OpenFlow device list:

1.     Click the Service tab.

2.     From the navigation tree, select VAN SDN Manager > Network Virtualization > OF Device Virtualization.

Adding virtual OpenFlow devices

Add one or more virtual OpenFlow devices individually or in batches. When adding virtual OpenFlow devices in batches, make sure the virtual OpenFlow devices to be added do not have overlapping VLANs. Otherwise, traffic cannot be correctly processed in a VLAN on which multiple instances take effect. SDNM uses the following rules:

·     SDNM prohibits the addition of a virtual OpenFlow device if it includes a VLAN on which another virtual OpenFlow device has taken effect.

·     If non-existent VLANs for a new virtual OpenFlow device are specified, SDNM creates the VLANs after the virtual OpenFlow device is activated.

When a virtual OpenFlow device is added, SDNM assigns an interface to the device. For information about adding or modifying an interface for the virtual OpenFlow device, see "Adding virtual OpenFlow devices."

To add virtual OpenFlow devices:

1.     Access the virtual OpenFlow device list page.

2.     Click Add in the virtual OpenFlow device list.

3.     Configure the following parameters:

?     Instance Name—Enter the label of the virtual OpenFlow device. On the OpenFlow switch, multiple virtual OpenFlow instances cannot be configured with the same instance name.

?     OF Switch—Select the OpenFlow switch to which the virtual OpenFlow device belongs. The list includes only OpenFlow switches that have been added to SDNM. For information about adding an OpenFlow switch to SDNM, see "Adding devices to IMC."

?     Controller—Select the controller that manages the virtual OpenFlow device.

?     VLAN (Available)—Specify the ID of the VLAN on which the virtual OpenFlow device takes effect.

?     VLAN Mask—Enter the VLAN mask of the OpenFlow switch. The VLANs to be associated are calculated by a bitwise AND operation on the specified VLAN ID and mask. The VLAN mask supports non-contiguous 1s and ignores all 0 bits. If the OpenFlow switch does not support the VLAN mask, this field is grayed out. For example, if the entered VLAN ID is 17 and VLAN mask is 4094, the bitwise AND operation result is 16. Because the lowest-order bit of the VLAN mask is 0, the lowest-order bit of 16 can be 0 or 1. The VLANs in which the OpenFlow device takes effect is VLAN 16 and VLAN 17.

?     In-Band Management VLAN—Enter the ID of the in-band management VLAN for the virtual OpenFlow device. In this VLAN, the virtual OpenFlow device establishes connections to the controller.

?     Expected DPIDExpected DPID of the virtual OpenFlow device that is populated when an OpenFlow switch and a controller have been selected. The rules for generating the DPID vary with device models.
