8 100 Davide Pesavento
* commands to create, modify, and destroy faces
9
* a dataset containing the description of all active faces and their counters
10
* a dataset containing the description of all active channels
11
* a notification stream for face events
12 1 Junxiao Shi
13 45 Junxiao Shi
Face Management commands, datasets, and notifications are available under namespace `ndn:/localhost/nfd/faces`.

## FaceUri
17 1 Junxiao Shi
18 27 Junxiao Shi
A FaceUri represents the underlying protocol and address used by a Face.  
19
Every Face has two FaceUris: one for local endpoint, and the other for remote endpoint.

## Static Face Attributes
113
114
**FaceScope** indicates whether the face is local for [[ScopeControl|scope control]] purposes.
115
116
* non-local(=0)
117
* local(=1)
118
119
**FacePersistency** indicates whether the face is persistent.
120
121
* on-demand(=1), face closes if it remains idle for some time
122
* persistent(=0), face remains open until it's explicitly destroyed or there's a transport failure
123
* permanent(=2), face remains open until it's explicitly destroyed; transport failures will be recovered internally
124
125
**LinkType** indicates the type of communication link.
126
127
* point-to-point(=0), communication with one peer
128
* multi-access(=1), communication with a multicast group
129 75 Davide Pesavento
* ad-hoc(=2), communication over a wireless ad hoc network
130 52 Junxiao Shi
131
**LocalFieldsEnabled** indicates whether the face allows [[NDNLPv2]] NextHopFaceId, CachePolicy, IncomingFaceId fields.
132
133
* yes(=1), allows these fields; this is valid only if FaceScope=local
134
* no(=0), disallows these fields
135
136 74 Eric Newberry
**LpReliabilityEnabled** indicates whether the face has the [[NDNLPv2]] reliability feature enabled.
137 69 Eric Newberry
138
* yes(=1), enables this feature
139
* no(=0), disables this feature
140 1 Junxiao Shi
141 74 Eric Newberry
**CongestionMarkingEnabled** indicates whether the face has congestion marking based upon send queue length enabled.
142
143
* yes(=1), enables this feature
144
* no(=0), disables this feature
145
146
**BaseCongestionMarkingInterval** indicates the base marking interval for congestion marking.
147
148 102 Davide Pesavento
* The value of this attribute is the base marking interval in nanoseconds, which is used to compute the interval at which congested packets will be marked.
149 74 Eric Newberry
150
**DefaultCongestionThreshold** indicates the default congestion threshold if the face does not support retrieving the send queue capacity.
151
152 102 Davide Pesavento
* The value of this attribute is the default congestion threshold in bytes.
153 74 Eric Newberry
154 85 Eric Newberry
**Mtu** contains a user-specified MTU to override the automatic MTU of the transport.
155
156 102 Davide Pesavento
* The value of this attribute is the MTU of the transport in bytes. A transport type may limit the acceptable range of this value or even ignore it altogether.
157 85 Eric Newberry
158 52 Junxiao Shi
### Flags and Mask
159
160
Some attributes are collected as inclusive OR into a **Flags** field in commands and datasets.
161
These attributes are: (bit 0 is the least significant bit)
162
163
* bit 0: LocalFieldsEnabled
164 1 Junxiao Shi
* bit 1: LpReliabilityEnabled
165 74 Eric Newberry
* bit 2: CongestionMarkingEnabled
166 55 Junxiao Shi
167 1 Junxiao Shi
## Control Commands
168
169 20 Junxiao Shi
[[ControlCommand]] **management-module**: `faces`
170 41 Junxiao Shi
171
### Create a face
172 1 Junxiao Shi
173
**command-verb**: `create`
174 46 Junxiao Shi
175
ControlParameters fields:
176 1 Junxiao Shi
177
* **Uri** (required): canonical remote FaceUri of the face to create.
178 72 Davide Pesavento
* **LocalUri** (optional): canonical local FaceUri of the face to create; e.g., FaceUri of the local interface for an Ethernet unicast face.
179 1 Junxiao Shi
* **FacePersistency** (optional): either *persistent* or *permanent*; creating *on-demand* faces is not permitted. The default is *persistent*. See "static face attributes" for more information.
180 74 Eric Newberry
* **BaseCongestionMarkingInterval** (optional): see "static face attributes".
181
* **DefaultCongestionThreshold** (optional): see "static face attributes".
182 85 Eric Newberry
* **Mtu** (optional): see "static face attributes".
183 72 Davide Pesavento
* **Flags** (optional): see "static face attributes".
184 83 Davide Pesavento
* **Mask** (optional): MUST be specified if *Flags* is present, and omitted if *Flags* is omitted.
185 1 Junxiao Shi
186 65 Davide Pesavento
This command allows the creation of UDP unicast, Ethernet unicast, and TCP faces only.  
187 50 Junxiao Shi
If the command succeeds, the \<body> of the ControlResponse block contains the ControlParameters describing the current properties of the created face:
188 1 Junxiao Shi
189 64 Alex Afanasyev
* **FaceId**
190 1 Junxiao Shi
* **Uri**
191 64 Alex Afanasyev
* **LocalUri**
192 1 Junxiao Shi
* **FacePersistency**
193 78 Eric Newberry
* **BaseCongestionMarkingInterval** (optional)
194
* **DefaultCongestionThreshold** (optional)
195 85 Eric Newberry
* **Mtu** (optional)
196 90 Eric Newberry
* **Flags**: contains effective values for the *LocalFieldsEnabled*, *LpReliabilityEnabled*, and *CongestionMarkingEnabled* bits.
197 66 Davide Pesavento
198 97 Davide Pesavento
If this creation would conflict with an existing face (e.g., same underlying protocol and remote endpoint), the command fails with StatusCode 409, and the \<body> of the ControlResponse block contains the ControlParameters describing the existing face, with the same fields as above.
199 52 Junxiao Shi
200 1 Junxiao Shi
If the request attempts to create a face other than UDP unicast, Ethernet unicast, or TCP, or if a static property specified in the request is not acceptable, the command fails with StatusCode 406.
201 79 Eric Newberry
202 1 Junxiao Shi
If face creation fails due to a socket error (e.g. TCP connection timeout), the command fails with StatusCode 504.
203
204 88 Eric Newberry
If *BaseCongestionMarkingInterval* or *DefaultCongestionThreshold* are omitted from the ControlParameters sent with the creation command, the omitted static properties are left at their implementation-defined default values.
205 1 Junxiao Shi
206 95 Eric Newberry
If *Mtu* is omitted from the ControlParameters sent with the creation command, the automatic MTU of the transport is used as the MTU of the face. A forwarder MAY impose an implementation-defined minimum to the MTU specified during face creation. The current minimum in NFD is 64 bytes. In the response, the *Mtu* field in ControlParameters contains the effective MTU of the face (in bytes), capped at a maximum of `MAX_NDN_PACKET_SIZE` (8800 bytes), even if the MTU of the underlying transport is infinite. If *Mtu* is omitted from the response, the face and/or forwarder does not support MTU reporting.
207 85 Eric Newberry
208 84 Davide Pesavento
### Update the static properties of a face
209 1 Junxiao Shi
210 52 Junxiao Shi
**command-verb**: `update`
211 1 Junxiao Shi
212
ControlParameters fields:
213 64 Alex Afanasyev
214
* **FaceId** (optional)
215 81 Davide Pesavento
* **FacePersistency** (optional): one of *on-demand*, *persistent*, or *permanent*. See "static face attributes" for more information.
216 1 Junxiao Shi
* **BaseCongestionMarkingInterval** (optional): see "static face attributes".
217
* **DefaultCongestionThreshold** (optional): see "static face attributes".
218 90 Eric Newberry
* **Flags** (optional): allows *LocalFieldsEnabled*, *LpReliabilityEnabled*, and *CongestionMarkingEnabled* only. See "static face attributes" for more information.
219 81 Davide Pesavento
* **Mask** (optional): MUST be specified if *Flags* is present, and omitted if *Flags* is omitted.
220 52 Junxiao Shi
221 101 Davide Pesavento
If *FaceId* is omitted or is set to zero, it is implied to be that of the requesting face (self-update).
222
If the face does not exist, the command fails with StatusCode 404.
223 1 Junxiao Shi
224 101 Davide Pesavento
The static properties of the face are updated as indicated.
225 81 Davide Pesavento
If an optional property field is omitted or a bitfield is zero in *Mask*, that static property remains unchanged.
226 1 Junxiao Shi
If no static properties are changed, this command does nothing, but is still considered successful.
227 55 Junxiao Shi
228 1 Junxiao Shi
If the command succeeds, \<body> in ControlResponse block contains ControlParameters describing the current properties of the face:
229
230
* **FaceId**
231
* **FacePersistency**
232 78 Eric Newberry
* **BaseCongestionMarkingInterval** (optional)
233
* **DefaultCongestionThreshold** (optional)
234 81 Davide Pesavento
* **Flags**: contains effective values for *LocalFieldsEnabled*, *LpReliabilityEnabled*, and *CongestionMarkingEnabled* bits.
235 1 Junxiao Shi
236
If any of the requested changes is invalid, none of the changes should be performed, and this command fails with StatusCode 409.
237 81 Davide Pesavento
The \<body> in ControlResponse block contains ControlParameters that includes only invalid fields; if some of the bit fields chosen in *Flags*+*Mask* is invalid, the \<body> block should also contain a *Mask* field indicating which bits are invalid, and echo back the original *Flags* field.
238
If the request had been sent without those fields (or bitfields in *Mask*), it would have been successful.
239 20 Junxiao Shi
240 1 Junxiao Shi
### Destroy a face
241 20 Junxiao Shi
242 26 Junxiao Shi
**command-verb:** `destroy`
243 20 Junxiao Shi
244 39 Junxiao Shi
ControlParameters fields:
245 1 Junxiao Shi
246 64 Alex Afanasyev
* **FaceId** (required)
247 39 Junxiao Shi
248 1 Junxiao Shi
If the specified face does not exist, this command does nothing, but is still considered successful.
249
250 40 Junxiao Shi
## Face Dataset

### Query operation
316 1 Junxiao Shi
317 37 Junxiao Shi
The query operation allows one to retrieve a subset of face dataset that contains faces satisfying a filter.
318
319
To run a query, the consumer should express an Interest with Name: `ndn:/localhost/nfd/faces/query/<filter>`, where `<filter>` is a **FaceQueryFilter** block that specifies zero or more conditions.
320
321
    FaceQueryFilter ::= FACE-QUERY-FILTER-TYPE TLV-LENGTH

* **FaceId** permits a face if its FaceId equals the value
334
* **UriScheme** permits a face if the scheme part of its local FaceUri or remote FaceUri equals the value
335
* **Uri** permits a face if its remote FaceUri equals the value
336 1 Junxiao Shi
* **LocalUri** permits a face if its local FaceUri equals the value
337
* **FaceScope** permits a face if its *FaceScope* attribute equals the value
338 39 Junxiao Shi
* **FacePersistency** permits a face if its *FacePersistency* attribute equals the value
339 37 Junxiao Shi
* **LinkType** permits a face if its *LinkType* attribute equals the value
340
341
A face must satisfy ALL conditions to satisfy the filter.
342 1 Junxiao Shi
Faces that satisfy the filter are represented by **FaceStatus** blocks, and published as a [[StatusDataset]] under the Interest Name (a Data packet's Name would be `ndn:/localhost/nfd/faces/query/<filter>/<version>/<segment>`).
343 37 Junxiao Shi
344 41 Junxiao Shi
Examples of filters:
345 1 Junxiao Shi
346 75 Davide Pesavento
* a specific face: `FaceId=260`
347
* a specific TCP tunnel: `Uri=tcp4://192.0.2.1:6363`  
348
  (note: FaceUri must precisely match the canonical form: use either "tcp4" or "tcp6" instead of "tcp", use IP address instead of domain name, include port number)
349
* all TCP tunnels: `UriScheme=tcp`  
350
  (note: "tcp" permits both "tcp4" and "tcp6", "udp" permits both "udp4" and "udp6")
351
* all UDP multi-access faces: `UriScheme=udp` && `LinkType=multi-access`
352
* all Ethernet faces: `UriScheme=ether`  
353
  (note: UriScheme matches against both local and remote FaceUri, "dev" also works)
354 1 Junxiao Shi
* all faces: no condition  
355 75 Davide Pesavento
  (note: this is equivalent to face dataset, and face dataset should be preferred for this purpose)

## Channel Dataset
358
359 20 Junxiao Shi
Description of all active channels is published as a [[StatusDataset|Status Dataset]] at `ndn:/localhost/nfd/faces/channels`.
360 1 Junxiao Shi
361
Each channel is represented by a **ChannelStatus** block:
362 20 Junxiao Shi
363
    ChannelStatus    := CHANNEL-STATUS-TYPE TLV-LENGTH
364 21 Alex Afanasyev
                          LocalUri
365 20 Junxiao Shi
366 83 Davide Pesavento
* **LocalUri** is a FaceUri representing the channel's local endpoint.

## Face Status Change Notification
369
370
Face status change events are published as a [[Notification|Notification Stream]] at `ndn:/localhost/nfd/faces/events`.
371 1 Junxiao Shi
Notifications of all faces are sent into the same notification stream.
372 37 Junxiao Shi
373 83 Davide Pesavento
The Content of each notification Data packet is a **FaceEventNotification** block:
374 23 Alex Afanasyev
375 37 Junxiao Shi
    FaceEventNotification ::= FACE-EVENT-NOTIFICATION-TYPE TLV-LENGTH
376 40 Junxiao Shi
                                FaceEventKind
377
                                FaceId
378
                                Uri
379 25 Junxiao Shi
                                LocalUri
380 23 Alex Afanasyev
                                FaceScope
381
                                FacePersistency

                                Flags
384 23 Alex Afanasyev
    
385 9 Junxiao Shi
    FaceEventKind         ::= FACE-EVENT-KIND-TYPE TLV-LENGTH
386
                                nonNegativeInteger
387
388 1 Junxiao Shi
**FaceEventKind** indicates the kind of event. Its possible values are:
389 34 Junxiao Shi
390 83 Davide Pesavento
* 1 = face is created
391
* 2 = face is destroyed
392
* 3 = face goes UP (from DOWN state)
393
* 4 = face goes DOWN (from UP state)
