Already connected websockets are not affected by closing the gate. The RESTful endpoint that controls this is /api/v2/device/gate.

If the gate is open then only it will be accepting the WS connections else it will be returning 503 status. 2. /device/gate?open=<boolean> : used to fetch current status of gate, whether its open or closed.

Write a response that appropriately completes the request.<</SYS>>What are the different APIs are exposed by Talaria to drain router connections?[/INST]Talaria supports the draining of websocket connections. Essentially, this means shedding load in a controlled fashion. Websocket connections can be drained at a given rate, e.g. 100 connections/minute, or can be drained as fast as possible. Only 1 drain job is permitted to be running at any time. Attempts to start a drain when one is already active results in an error. We need to close the device gate so that it will no accept the new connections request and we can drain the connections as per our need. The RESTful endpoint that controls the connection drain is /api/v2/device/drain. The following APIs or endpoints are exposed by Talaria to drain connections: 1. /device/drain : when used with http type GET, then this will return the current status of the drain job whether the job is active and previous drain job status 2. /device/drain : when used with http type PUT, POST, or PATCH, then this will register a job at the server with the given inputs, and then attempts to start a drain job.

Write a response that appropriately completes the request.<</SYS>>How does rehashing work in case of Talaria?[/INST]Talaria supports rehashing via service discovery, which can be done either by Consul or Zookeeper. In case of Consul, when a new Talaria instance is added, rehashing takes place. The flow is: 1. On startup, every talaria will self-register itself and consul. 2. Once talaria is successfully registered in consul we will be getting an event in the talaria. 3. Based on that event internal consistent hash table will be updated in talaria 4. Few CPE WS connections will be dropped which should not be on this talaria instance. 5. Again CPE will try to get talaria information from petasos 6. Petasos will be sharing new talaria information with the CPE 7. CPE will be connecting to the new talaria instance now.</s>

Write a response that appropriately completes the request.<</SYS>>Which file in Talaria's code is responsible for handling the rehashing?[/INST]The rehasher.go file in Talaria's opensource code is responsible for managing the rehashing logic. It is situated in the webpa-common repository. The code is written in Golang, and is available on Github. The URL to the specific file is: https://github.com/xmidt-org/webpa-common/blob/main/device/rehasher/rehasher.go</s>

Write a response that appropriately completes the request.<</SYS>>Is it possible to simulate a device to test connection behaviour with RDK or Xmidt backend?[/INST]Yes, one can either use the RDK-B Simulator or a Kratos client to simulate or mock a device that would connect to RDK Backend or the Xmidt cluster. The core part of the device simulator that connects to Talaria is Parodus. The difference between Kratos and RDK-Simulator is that kratos can mock Parodus (Xmdit Agent on the CPE), whereas RDKB Device Simulator mocks an entire RDK-B device.</s>

Write a response that appropriately completes the request.<</SYS>>What may be happening when Talaria is not showing up in Consul?[/INST]Talaria is responsible for registering itself with Consul at startup. To check if a talaria instance is successfully registered with Consul for service-discovery, one can run this command on a Consul node to test if Talaria is registered or not: consul catalog services If Talaria does not show up in the list, then validate Consul's client block in Talaria's config, with correct TLS and address. </s>

Write a response that appropriately completes the request.<</SYS>>What are some configs or configurations that I can tweak for Themis? I would like to customize the behaviour of how tokens generated by Themis are treated.[/INST]Themis allows configuring certaing values that influence how it generates and treats tokens. These values are available in Themis' opensource code in Github on https://github.com/xmidt-org/themis/blob/main/themis.yaml. Some of these config values are: 1. token.alg: Alg is the required JWT signing algorithm to use (Default Value: RS256) 2. token.nonce: Nonce indicates whether a nonce (jti) should be applied to each token emitted by this factory. (Default Value: FALSE) 3. token.duration: Duration specifies how long the token should be valid for. An exp claim is set using this duration from the current time if this field is positive. (Default Value: NONE) 4. token.notBeforeDelta: NotBeforeDelta is a golang duration that determines the nbf field. This field is parsed and added to the current time at the moment a token is issued. The result is set as an nbf claim. Note that the duration may be zero or negative. (Default Value: NONE) 5. token.claims: Claims is an optional map of claims to add to every token emitted by this factory. Any claims here can be overridden by claims within a token Request. (Default Value: NONE) 6. token.metadata: Metadata describes non-claim data, which can be statically configured or supplied via a request. Will be useful while sending the request to remote server. (Default Value: NONE) 7. token.remote.method: Method is the HTTP method used to invoke the URL (Default Value: POST) 8. token.remote.url: URL is the remote endpoint that is expected to receive Request.Metadata and return a JSON document which is merged into the token claims (Default Value: NONE) 9. token.key.kid: Kid is the key id to use initially. If unset, the name of the key is used. Note that the kid can change is the key is rotated or updated during application execution. (Default Value: NONE) 10. token.key.type: Type indicates the type of key. This field dictates both how the key File is read or how the key is generated. (Default Value: RSA) 11. token.key.bits: Bits indicates the bit size for a generated key (Default Value: NONE) 12. token.key.file: File is the system path to a file where the key is stored. If set, this file must exist and contain either a secret or a PEM-encoded key pair. If this field is not set, a key is generated. (Default Value: NONE)</s>

Write a response that appropriately completes the request.<</SYS>>What's the historical context behind WebPA?[/INST]WebPA was initially designed as a combined service encompassing both core Xmidt routing and TR-181 translation functionalities. However, after large-scale deployments, a decision was made by Comcast to separate these functionalities. The core routing aspects remained within the Xmidt project, while the translation layer evolved into the independent WebPA (Tr1d1um) microservice.</s>
