1 Introduction
This document describes the functions of the POF (Protocol Oblivious Forwarding). The
content here is mainly about how to use the POF Controller GUI.
The target readers are the researchers, developers, and telecom engineers who relate to the
router, switch, especially the software defined network.
The prototype supports most features of OpenFlow version 1.3, such as multiple tables,
groups, meters, counters, instructions, actions, and metadata.
Below are some differences between POF and OpenFlow version 1.3:
1) POF has no push-MPLS, push-PBB, and push-VLAN actions. These actions are replaced with
the ADD_FIELD action.
2) POF has no pop-MPLS, pop-PBB, and pop-VLAN actions. These actions are replaced with
the DELETE_FIELD action.
3) POF has no decrement TTL action. It is replaced with the MODIFY_FIELD action.
4) The SET_FIELD action in POF does not have any protocol-specific parameters like
OFPXMT_OFB_IPV4_SRC and OFPXMT_OFB_TCP_SRC. Instead, the position and length
of the filed in the packet are used as parameters.
These differences reflect the protocol-oblivious nature of POF. The forwarding plane does not
need to understand the protocol type and the meaning of each field. The protocol header fields are
abstracted as simple offset and length tuples.

2 Glossary
Metadata: a register used to carry global information from one table to the next.
MM: masked match table type. The matching key can have arbitrary bits masked as “don’t
care” bits. A typical example is ACL table.
LPM: longest prefix match table type. A typical example is IP FIB.
EM: exact match table type. A typical example is L2 MAC table.
VPN: virtual private network.
VRF: VPN routing and forwarding.

3 FEATURES
This section describes the functions of the POF Controller. Please refer to the use cases for
detailed configurations.
3.1
Save and Load data
To simplify the configuration, POF controller can save all the configuration data into one file.
The configuration data can be loaded from the file for later usage.
Click “File” button in menu bar and choose “Save”/“Load” to save/load data.
3.2
Resize Window
The GUI is full screen mode when startup.
In full screen mode, click “File” and “Max Screen” to switch to max screen mode.
In max screen mode, click “File” and “Full Screen” to switch to full screen mode.
3.3
Select Switch
Select the switch in the pull-down menu on the right side of “Switch”.
2013-7-18

3.4
Configure Group
A group entry contains an ordered list of actions. The ability for a flow entry to point to a
group enables additional methods of forwarding. A group entry includes the following items:

Group type: OFPGT_ALL: Execute all actions in the group. This group is used for multicast
or broadcast forwarding. The options OFPGT_SELECT, OFPGT_INDIRECT, OFPGT_FF
are not supported in POF.

Switch ID: the device ID, select one device for group.

Group ID: uniquely identifying the group, assigned automatically.

Counter ID: updated when packets are processed by a group, assigned automatically.

Action Num: the total number of the actions included in the group, cumulated automatically.

Action: an ordered list of actions.
1) Click “Group” button in menu bar.
2) Click “Group” and “New Group” to add a new group table.
3) Click “group” and “Group Type”; choose the type in pull-down menu.
4) Click “Action” and “New Action”; configure actions of the group table. See action
configurations in the later chapters.
2013-7-18
Page 8, Total 41
5) “ActionNum” and “GroupID” are automatically generated. Click “SAVE” button to submit all
group configurations.
Refer to Section 5.2 for the configuration.
3.5
Configure Meter
A meter measures the rate of packets assigned to it and enables controlling the rate of those
packets. Meters are attached directly to flow entries. Any flow entry can specify a meter in its
instruction. The meter measures and controls the aggregated rate of all the flow entries to which it
is attached.
POF Controller only defines the meter as a rate limiter. The rate is the maximum output rate.
POF Controller supports only the pass or drop action to the packet. When the output rate exceeds
the rate specified by the meter, the packet is dropped.
A meter includes the following items:

Switch ID: the device ID, select one device for meter.

Meter ID: uniquely identifying one meter; assigned automatically.

Rate: The maximum output rate. The unit is kbps for the total frame length.
1) Click “Meter” button in menu bar.
2) Input the meter rate; click the
3) Click the
icon to submit. Meter ID is automatically generated.
icon if you want to delete a meter ID.
4) Click “SAVE” button to submit all meter configurations.
2013-7-18
Page 9, Total 41
Attention: The meter is single rate and we support only pass or drop action to the
packet.
3.6
Configure Protocol
One packet contains multiple fields. Each field includes a name, an offset (in bit unit), and a
length (in bit unit). The packet has a name too, and the name can show the packet protocol. In the
latter table configuration, it needs to select the packet name first and then select the fields of the
packet.
POF Controller defines a packet template as only one protocol layer header. For example, a
packet template named Ethernet can be defined to include these fields:

Destination: offset is 0, length is 48.

Source: offset is 48, length is 48.

Type: offset is 96, length is 16.
Then a packet template named IPv4 can be defined to include all the IPv4 header fields.
The Ethernet packets are processed in the first flow table, get a matched flow entry, and then go to
the second flow table for IPv4 processing. We can also define a packet template to cover layer 2,
layer 3, and layer 4 headers, even the payload data.
1) Click plus icon on the right side of “Protocol”.
2) Take turns to input name and length of each field, and click “OK” to submit the field. Offset
of the field is automatically generated.

3) Click “SAVE”, enter protocol name, and click “SAVE” to confirm protocol configuration.
4) Click the protocol name label in the line “Protocol” to see the protocol configuration.
Refer to Section 4.2 for the configuration.
3.7
Configure Metadata
POF-enabled switch contains multiple flow tables. The POF pipeline processing defines how
packets interact with those flow tables.
Metadata is in fact a register that is used to carry global information between tables. A table
process can record a value in the metadata and the value can be used in another table process
The metadata contains multiple fields. Each field is referenced by the following items:

Name: user defined string for reference in instructions WRITE_METADATA and
WRITE_METADATA_FROM_PACKET.
A metadata field can also be used as a part of
the match fields for the flow entry in the table.

Offset: the field position in the metadata structure.

Length: length of the field.
The name is convenient for user configuration in GUI but meaningless to the POF-enabled
switch.
To reference a metadata field, the switch uses just the offset and the length.
2013-7-18
Page 11, Total 41
1) Double click “Metadata” label in the line “Protocol”.
2) Take turns to input name and length of each field, and click “OK” to submit the field.
3) Click “SAVE” confirm metadata configuration.
4) Click the “Metadata” label in the line “Protocol” to see metadata configuration.
Refer to Section 4.2 for the configuration.
Attention:
Metadata definition is based on the switch. Different switches may have different metadata
size and different field definition. In our switch, the first 32bit of metadata is fixed to keep some
packet information automatically get from hardware before POF process; the other part is freely
defined.
3.8
Device Information
Click the
icon in the lower right corner to display device information. Device
information includes:

Device info: all the devices connected to the controller.

Port info: port information of all the devices. Each of the network cards will have a Port ID.
2013-7-18
Page 12, Total 41
Choose “POFEnable” in the rank “OpenFlow Enabled” to enable POF forwarding for a port.

Flow table resource: the number of counter, meter, group, table, and table entry supported
by each device.

Recent error messages: Last 10error messages

Packet-In messages: Last 10 packet-in messages.
3.9
Configure Flow Table
A flow table descriptor includes the following fields:

Table ID: uniquely identifying one table; assigned automatically.

Table Name: a user defined string for reference in GUI.

Switch ID: the device ID, select one device for flow table.

Table Type: select one from MM, LPM, EM, and linear. The type determines how to
execute the match process to get a flow entry in the table.
For an MM table, the non wildcard bits in the match keys will be omitted in the match
process.
For an LPM table, the entry with the longest matching prefix with the key is returned.
For an EM table, the match key has to be matched bit by bit.
For a linear table, an index is used to retrieve a table entry.

Table Size: size of the table; should not exceed the resource limit of the device.

Key length: length of match key; calculated automatically after selecting the table fields.

Table Field: the match fields selected to execute the match process against the table. The
match key source is from packet data or from metadata. A direct table does not need to set
2013-7-18
Page 13, Total 41
the table field.

Flow entry: a flow table contains a number of flow entries. A MM, LPM or EM table needs
to execute the match process to find the matching flow entry. A direct table uses the entry
index in the GOTO_DIRECT_TABLE instruction to retrieve the table entry directly.
1) Click the plus icon in the left of “Add New Table” add a new table. Click the diamond to
configure the new table.
2) Click “Table Name”, input the table name, press “Enter” to confirm.

3.10 Configure Flow Entry
A flow entry includes the following items:

Flow entry ID: uniquely identifying one entry; assigned automatically.

Priority: matching precedence of the flow entry. 0 is the lowest priority. The larger value
means higher priority.

Entry field: packet data or metadata fields to match against. These fields inherit from the
table fields for a MM, LPM, and EM table. No entry field needs to be set for a linear table.
An entry field contains ID, name, offset, length, value, and mask. The ID, name, offset, and
length inherit from the table field which cannot be modified. Only the value and mask need
to be set.

Instruction: the pipeline processing instructions which will be executed when the flow entry
is matched against packets.

Counter: count the number of times the flow entry is matched; updated for each matching
packet.
Refer to use case for the configuration.
1) Click “Flow Entry”; click the plus icon in the left of “Flow Entries” to add an entry.

In this use case, you’ll send an ETH + IPv4 packet to POF switch. Following actions are
needed to forward this packet. First, lookup first flow table to parse L2 header. Second, get port
control information through input port. Third, parse L3 packet and determine whether to do ACL
according to the packet content. Finally, get routing information; modify fields in packet, and send
this packet. Four tables should be configured:
