5 | 20 | Junxiao Shi | **Face Management** is a module of [[Management|NFD Management protocol]]. |
6 | It provides: |
||
7 | 1 | Junxiao Shi | |
8 | 20 | Junxiao Shi | * commands to create and destroy faces |
9 | * commands to enable and disable [[LocalControlHeader]] features on a face |
||
10 | * a dataset of description of all active faces and their counters |
||
11 | 33 | Junxiao Shi | * a dataset of description of all active channels |
12 | 20 | Junxiao Shi | * a notification stream for face creating and destroying events |
13 | 1 | Junxiao Shi | |
14 | 45 | Junxiao Shi | Face Management commands, datasets, and notifications are available under namespace `ndn:/localhost/nfd/faces`. |

17 | 20 | Junxiao Shi | ## FaceUri |
18 | 1 | Junxiao Shi | |
19 | 27 | Junxiao Shi | A FaceUri represents the underlying protocol and address used by a Face. |
20 | Every Face has two FaceUris: one for local endpoint, and the other for remote endpoint. |

37 | 1 | Junxiao Shi | |
38 | 61 | Davide Pesavento | LocalUri of a NIC-associated UDP face has the form: |
39 | |||
40 | `udp[4|6]+dev://<NIC>:<port>` |
||
41 | |||
42 | 1 | Junxiao Shi | This is only used in face dataset. |
43 | 61 | Davide Pesavento | |

113 | ## Static Face Attributes |
||
114 | |||
115 | **FaceScope** indicates whether the face is local for [[ScopeControl|scope control]] purposes. |
||
116 | |||
117 | * non-local(=0) |
||
118 | * local(=1) |
||
119 | |||
120 | **FacePersistency** indicates whether the face is persistent. |
||
121 | |||
122 | * on-demand(=1), face closes if it remains idle for some time |
||
123 | * persistent(=0), face remains open until it's explicitly destroyed or there's a transport failure |
||
124 | * permanent(=2), face remains open until it's explicitly destroyed; transport failures will be recovered internally |
||
125 | |||
126 | **LinkType** indicates the type of communication link. |
||
127 | |||
128 | * point-to-point(=0), communication with one peer |
||
129 | * multi-access(=1), communication with a multicast group |
||
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 | 70 | 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 | |||
141 | 52 | Junxiao Shi | ### Flags and Mask |
142 | |||
143 | Some attributes are collected as inclusive OR into a **Flags** field in commands and datasets. |
||
144 | These attributes are: (bit 0 is the least significant bit) |
||
145 | |||
146 | * bit 0: LocalFieldsEnabled |
||
147 | 70 | Eric Newberry | * bit 1: LpReliabilityEnabled |
148 | 55 | Junxiao Shi | |
149 | 52 | Junxiao Shi | In `create` and `update` commands, the **Flags** field must be accompanied by a **Mask** field which indicates which static attributes should be set; in other words, Flags and Mask fields must be both specified or both omitted. |
150 | Bits in the Mask field is arranged in the same order as the Flags field. |
||
151 | If a bit in Mask is zero, `faces/create` command keeps the default setting of the attribute, `faces/update` command keeps the old value of the attribute. |
||
152 | 20 | Junxiao Shi | |
153 | 1 | Junxiao Shi | ## Control Commands |
154 | |||
155 | 20 | Junxiao Shi | [[ControlCommand]] **management-module**: `faces` |
156 | 41 | Junxiao Shi | |
157 | ### Create a face |
||
158 | 1 | Junxiao Shi | |
159 | **command-verb**: `create` |
||
160 | 46 | Junxiao Shi | |
161 | ControlParameters fields: |
||
162 | 1 | Junxiao Shi | |
163 | 65 | Davide Pesavento | * **Uri** (required): canonical remote FaceUri of the face to create (e.g., UDP unicast, Ethernet unicast, or TCP) |
164 | * **LocalUri** (optional): canonical local FaceUri of the face to create (e.g., FaceUri of the local interface for an Ethernet unicast face) |
||
165 | * **FacePersistency** (optional): either *persistent* or *permanent*; creating on-demand faces is not permitted. |
||
166 | 20 | Junxiao Shi | The default is *persistent*. |
167 | 1 | Junxiao Shi | See "static face attributes" for more information. |
168 | 64 | Alex Afanasyev | * **Flags** (optional): see "static face attributes". |
169 | * **Mask** (optional): see "static face attributes". |
||
170 | 1 | Junxiao Shi | |
171 | 65 | Davide Pesavento | This command allows the creation of UDP unicast, Ethernet unicast, and TCP faces only. |
172 | 50 | Junxiao Shi | If the command succeeds, the \<body> of the ControlResponse block contains the ControlParameters describing the current properties of the created face: |
173 | 64 | Alex Afanasyev | |
174 | 66 | Davide Pesavento | * **FaceId** |
175 | 68 | Junxiao Shi | * **Uri** |
176 | 64 | Alex Afanasyev | * **LocalUri** |
177 | 1 | Junxiao Shi | * **FacePersistency** |
178 | 70 | Eric Newberry | * **Flags**: contains effective values for *LocalFieldsEnabled* and *LpReliabilityEnabled* bits |
179 | 68 | Junxiao Shi | |
180 | If this creation would conflict with an existing face (e.g., same underlying protocol and remote endpoint, or a NIC-associated permanent face), 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. |
||
181 | 52 | Junxiao Shi | |
182 | 66 | Davide Pesavento | 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. |
183 | 52 | Junxiao Shi | |
184 | If face creation fails due to a socket error (e.g. TCP connection timeout), the command fails with StatusCode 504. |
||
185 | 1 | Junxiao Shi | |
186 | ### Update static properties |
||
187 | 20 | Junxiao Shi | |
188 | 1 | Junxiao Shi | **command-verb**: `update` |
189 | 20 | Junxiao Shi | |
190 | 52 | Junxiao Shi | ControlParameters fields: |
191 | 64 | Alex Afanasyev | |
192 | * **FaceId** (optional) |
||
193 | 1 | Junxiao Shi | * **FacePersistency** (optional): *on-demand* or *persistent* or *permanent* |
194 | 52 | Junxiao Shi | See "static face attributes" for more information. |
195 | 70 | Eric Newberry | * **Flags** (optional): allows *LocalFieldsEnabled* and *LpReliabilityEnabled* only, see "static face attributes". |
196 | 64 | Alex Afanasyev | * **Mask** (optional): see "static face attributes". |
197 | 52 | Junxiao Shi | |
198 | FaceId is the FaceId returned in [[FaceMgmt|Face Management]]. |
||
199 | If FaceId is omitted or is set to zero, it is implied as the requesting face (self updating). |
||
200 | 1 | Junxiao Shi | If face does not exist, this command fails with StatusCode 404. |
201 | |||
202 | Static properties of the face is updated. |
||
203 | 55 | Junxiao Shi | If an optional property field is omitted or a bitfield is zero in Mask, that static property remains unchanged. |
204 | If no static property is changed, this command does nothing, but is still considered successful. |
||
205 | |||
206 | If the command succeeds, \<body> in ControlResponse block contains ControlParameters describing the current properties of the face: |
||
207 | 1 | Junxiao Shi | |
208 | 64 | Alex Afanasyev | * **FaceId** |
209 | * **FacePersistency** |
||
210 | 70 | Eric Newberry | * **Flags**: contains effective values for *LocalFieldsEnabled* and *LpReliabilityEnabled* bits |
211 | 1 | Junxiao Shi | |
212 | 52 | Junxiao Shi | If any of the requested changes is invalid, none of the changes should be performed, and this command fails with StatusCode 409. |
213 | 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. |
||
214 | 62 | Davide Pesavento | If the request had been sent without those fields (or bitfields in Mask), it would have been successful. |
215 | 20 | Junxiao Shi | |
216 | 1 | Junxiao Shi | ### Destroy a face |
217 | 20 | Junxiao Shi | |
218 | 26 | Junxiao Shi | **command-verb:** `destroy` |
219 | 20 | Junxiao Shi | |
220 | 39 | Junxiao Shi | ControlParameters fields: |
221 | 1 | Junxiao Shi | |
222 | 64 | Alex Afanasyev | * **FaceId** (required) |
223 | 39 | Junxiao Shi | |
224 | 1 | Junxiao Shi | If the specified face does not exist, this command does nothing, but is still considered successful. |
225 | |||
226 | 40 | Junxiao Shi | ## Face Dataset |
227 | 1 | Junxiao Shi | |
228 | Description and counters of all active faces are published as a [[StatusDataset|Status Dataset]] at `ndn:/localhost/nfd/faces/list`. |
||
229 | 39 | Junxiao Shi | |
230 | Each face is represented by a **FaceStatus** block: |
||
231 | 1 | Junxiao Shi | |
232 | 39 | Junxiao Shi | FaceStatus ::= FACE-STATUS-TYPE TLV-LENGTH |
233 | FaceId |
||
234 | 37 | Junxiao Shi | Uri (remote FaceUri) |
235 | 39 | Junxiao Shi | LocalUri |
236 | 1 | Junxiao Shi | ExpirationPeriod? |
237 | FaceScope |
||
238 | FacePersistency |
||
239 | 52 | Junxiao Shi | LinkType |
240 | 1 | Junxiao Shi | Flags |
241 | NInInterests |
||
242 | 67 | Junxiao Shi | NInData |
243 | 1 | Junxiao Shi | NInNacks |
244 | 39 | Junxiao Shi | NOutInterests |
245 | 67 | Junxiao Shi | NOutData |
246 | 49 | Junxiao Shi | NOutNacks |
247 | NInBytes |
||
248 | 46 | Junxiao Shi | NOutBytes |
249 | |||
250 | Uri ::= URI-TYPE TLV-LENGTH |
||
251 | FaceUri in UTF-8 encoding |
||
252 | 39 | Junxiao Shi | |
253 | 46 | Junxiao Shi | LocalUri ::= LOCAL-URI-TYPE TLV-LENGTH |
254 | 1 | Junxiao Shi | FaceUri in UTF-8 encoding |
255 | 46 | Junxiao Shi | |
256 | 1 | Junxiao Shi | ; other TLVs have nonNegativeInteger as value |
257 | |||
258 | * **Uri** is a FaceUri representing remote endpoint. |
||
259 | 40 | Junxiao Shi | * **LocalUri** is a FaceUri representing local endpoint. |
260 | 39 | Junxiao Shi | * **ExpirationPeriod** is the remaining lifetime of this face. |
261 | 40 | Junxiao Shi | If this field is omitted, the face has infinite lifetime. |
262 | 46 | Junxiao Shi | Currently, this is applicable to on-demand datagram faces only. |
263 | 40 | Junxiao Shi | * **FaceScope** indicates whether the face is local for [[ScopeControl|scope control]] purposes. |
264 | 46 | Junxiao Shi | See "static face attributes" for more information. |
265 | 1 | Junxiao Shi | * **FacePersistency** indicates whether the face is persistent. |
266 | 40 | Junxiao Shi | See "static face attributes" for more information. |
267 | 52 | Junxiao Shi | * **LinkType** indicates the type of communication link |
268 | See "static face attributes" for more information. |
||
269 | 70 | Eric Newberry | * **Flags** contains these bitfields: *LocalFieldsEnabled*, *LpReliabilityEnabled*. |
270 | 46 | Junxiao Shi | See "static face attributes" for more information. |
271 | * **NInInterests**: number of incoming Interest packets since the face is established. |
||
272 | 67 | Junxiao Shi | * **NInData** counts the number of incoming Data packets since the face is established. |
273 | 46 | Junxiao Shi | * **NInNacks** counts the number of incoming Nack packets since the face is established. |
274 | 1 | Junxiao Shi | * **NOutInterests** counts the number of outgoing Interest packets since the face is established. |
275 | 67 | Junxiao Shi | * **NOutData** counts the number of outgoing Data packets since the face is established. |
276 | 37 | Junxiao Shi | * **NOutNacks** counts the number of outgoing Nack packets since the face is established. |
277 | * **NInBytes** counts the number of bytes of link layer packets received via this face. |
||
278 | This counter is initialized to zero when the face is established, and can wrap around after overflowing unsigned 64-bit integer range. |
||
279 | * **NOutBytes** counts the number of bytes of link layer packets sent via this face. |
||
280 | This counter is initialized to zero when the face is established, and can wrap around after overflowing unsigned 64-bit integer range. |
||
281 | |||
282 | ### Query Operation |
||
283 | 1 | Junxiao Shi | |
284 | 37 | Junxiao Shi | The query operation allows one to retrieve a subset of face dataset that contains faces satisfying a filter. |
285 | |||
286 | 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. |
||
287 | |||
288 | FaceQueryFilter ::= FACE-QUERY-FILTER-TYPE TLV-LENGTH |
||
289 | 40 | Junxiao Shi | FaceId? |
290 | UriScheme? |
||
291 | Uri? |
||
292 | 37 | Junxiao Shi | LocalUri? |
293 | FaceScope? |
||
294 | 1 | Junxiao Shi | FacePersistency? |
295 | 37 | Junxiao Shi | LinkType? |
296 | |||
297 | UriScheme ::= URI-SCHEME-TYPE TLV-LENGTH |
||
298 | string in UTF-8 |
||
299 | |||
300 | 40 | Junxiao Shi | * **FaceId** permits a face if its FaceId equals the value |
301 | * **UriScheme** permits a face if the scheme part of its local FaceUri or remote FaceUri equals the value |
||
302 | * **Uri** permits a face if its remote FaceUri equals the value |
||
303 | 1 | Junxiao Shi | * **LocalUri** permits a face if its local FaceUri equals the value |
304 | * **FaceScope** permits a face if its *FaceScope* attribute equals the value |
||
305 | 39 | Junxiao Shi | * **FacePersistency** permits a face if its *FacePersistency* attribute equals the value |
306 | 37 | Junxiao Shi | * **LinkType** permits a face if its *LinkType* attribute equals the value |
307 | |||
308 | A face must satisfy ALL conditions to satisfy the filter. |
||
309 | 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>`). |
310 | 37 | Junxiao Shi | |
311 | 41 | Junxiao Shi | Examples of filters: |
312 | 37 | Junxiao Shi | |
313 | 33 | Junxiao Shi | * a specific face: FaceId=260 |
314 | 40 | Junxiao Shi | * a specific TCP tunnel: Uri=tcp4://192.0.2.1:6363 |
315 | 33 | Junxiao Shi | note: FaceUri must precisely match the canonical form: use either "tcp4" or "tcp6" instead of "tcp", use IP address instead of DNS name, include port number |
316 | * all TCP tunnels: UriScheme=tcp |
||
317 | note: "tcp" permits both "tcp4" and "tcp6", "udp" permits both "udp4" and "udp6" |
||
318 | * all UDP multicast faces: UriScheme=udp & LinkType=multi-access |
||
319 | * all Ethernet faces: UriScheme=ether |
||
320 | 1 | Junxiao Shi | note: UriScheme matches on both local and remote FaceUri, "dev" also works |
321 | * all faces: no condition |
||
322 | note: this is equivalent to face dataset, and face dataset should be preferred for this purpose |
||
323 | 33 | Junxiao Shi | |
324 | ## Channel Dataset |
||
325 | |||
326 | 20 | Junxiao Shi | Description of all active channels is published as a [[StatusDataset|Status Dataset]] at `ndn:/localhost/nfd/faces/channels`. |
327 | 1 | Junxiao Shi | |
328 | Each channel is represented by a **ChannelStatus** block: |
||
329 | 20 | Junxiao Shi | |
330 | ChannelStatus := CHANNEL-STATUS-TYPE TLV-LENGTH |
||
331 | 21 | Alex Afanasyev | LocalUri |
332 | 20 | Junxiao Shi | |
333 | 1 | Junxiao Shi | * **LocalUri** is a FaceUri representing local endpoint. |
334 | 21 | Alex Afanasyev | |
335 | 37 | Junxiao Shi | ## Face Status Change Notification |
336 | |||
337 | Face status change events are published as a [[Notification|Notification Stream]] at `ndn:/localhost/nfd/faces/events`. |
||
338 | 1 | Junxiao Shi | Notifications of all faces are sent into the same notification stream. |
339 | 37 | Junxiao Shi | |
340 | The Content of each notification Data packet is a `FaceEventNotification` block: |
||
341 | 23 | Alex Afanasyev | |
342 | 37 | Junxiao Shi | FaceEventNotification ::= FACE-EVENT-NOTIFICATION-TYPE TLV-LENGTH |
343 | 40 | Junxiao Shi | FaceEventKind |
344 | FaceId |
||
345 | Uri |
||
346 | 25 | Junxiao Shi | LocalUri |
347 | 23 | Alex Afanasyev | FaceScope |
348 | FacePersistency |
||
349 | 58 | Eric Newberry | LinkType |
350 | 25 | Junxiao Shi | Flags |
351 | 23 | Alex Afanasyev | |
352 | 9 | Junxiao Shi | FaceEventKind ::= FACE-EVENT-KIND-TYPE TLV-LENGTH |
353 | nonNegativeInteger |
||
354 | |||
355 | 1 | Junxiao Shi | **FaceEventKind** indicates the kind of event. Its possible values are: |
356 | 34 | Junxiao Shi | |
