This - will be picked up by the Link Monitor, which sends - a new event (L09 DOWN) to the policy. The policy - then will calculate which customer should be - impeded (throttled). This will continue, until SLAs - are violated, then a priority calculation will kick - in (Customer ``A`` is prioritized in the setup). - - .. container:: paragraph - - To initiate this, simply type ``link s5 s6 down`` - in the Mininet console followed by ``exit``. - - .. container:: paragraph - - If you have the video streams running, you will see - one or the other struggeling, depending on the - policy decision. - - .. container:: sect2 - - .. rubric:: Reset the Demo - :name: reset_the_demo - - .. container:: paragraph - - If you want to reset the demo, simple stop (in this - order) the following process - - .. container:: ulist - - - Link Monitor - - - APEX - - - Mininet - - - Floodlight - - .. container:: paragraph - - Then restart them in this order - - .. container:: ulist - - - Floodlight - - - Mininet - - - APEX - - - Link Monitor - - .. container:: sect2 - - .. rubric:: Monitor the Demo - :name: monitor_the_demo - - .. container:: paragraph - - Floodlight and APEX provide REST interfaces for - monitoring. - - .. container:: ulist - - - Floodlight: see `Floodlight - Docs <https://floodlight.atlassian.net/wiki/spaces/floodlightcontroller/pages/40403023/Web+GUI>`__ - for details on how to access the monitoring. In - a standard installation as we use here, pointing - browser to the URL - ``http://localhost:8080/ui/pages/index.html`` - should work on the same host - -VPN SLA Policy -^^^^^^^^^^^^^^ - - .. container:: sectionbody - - .. container:: paragraph - - The VPN SLA policy is designed as a MEDA policy. The - first state (M = Match) takes the trigger event (a - link up or down) and checks if this is a change to the - known topology. The second state (E = Establish) takes - all available information (trigger event, local - context) and defines what situation we have. The third - state (D = Decide) takes the situation and selects - which algorithm is best to process it. This state can - select between ``none`` (nothing to do), ``solved`` (a - problem is solved now), ``sla`` (compare the current - customer SLA situation and select one to impede), and - ``priority`` (impede non-priority customers). The - fourth and final state (A = Act) selects the right - action for the taken decision and creates the response - event sent to the orchestrator. - - .. container:: paragraph - - We have added three more policies to set the local - context: one for adding nodes, one for adding edges - (links), and one for adding customers. These policies - do not realize any action, they are only here for - updating the local context. This mechanism is the - fasted way to update local context, and it is - independent of any context plugin. - - .. container:: paragraph - - The policy uses data defined in Avro, so we have a - number of Avro schema definitions. - -Context Schemas ---------------- - - .. container:: sect1 - - .. container:: sectionbody - - .. container:: paragraph - - The context schemas are for the local context. We - model edges and nodes for the topology, customers, and - problems with all information on detected problems. - - .. container:: ulist - - - |avroSchemaEdges_link| - - |avroSchemaNodes_link| - - |avroSchemaCustomers_link| - - -Trigger Schemas ---------------- - - .. container:: sect1 - - .. container:: sectionbody - - .. container:: paragraph - - The trigger event provides a status as ``UP`` or - ``DOWN``. To avoid tests for these strings in the - logic, we defined an Avro schema for an enumeration (|avroSchemaLinkStatus_link|). - This does not impact the trigger system (it can still - send the strings), but makes the task logic simpler. - - - -Context Logic Nodes -------------------- - - .. container:: sect1 - - .. container:: sectionbody - - .. container:: paragraph - - The node context logic simply takes the trigger event - (for context) and creates a new node in the local - context topology (|cntxtNodes_link|). - -Context Logic Edges -------------------- - - .. container:: sect1 - - .. container:: sectionbody - - .. container:: paragraph - - The edge context logic simply takes the trigger event - (for context) and creates a new edge in the local - context topology (|cntxtEdges_link|). - - -Context Logic Customer ----------------------- - - .. container:: sect1 - - .. container:: sectionbody - - .. container:: paragraph - - The customer context logic simply takes the trigger - event (for context) and creates a new customer in the - local context topology (|cntxtCustomer_link|). - - -Logic: Match ------------- - - .. container:: sect1 - - .. container:: sectionbody - - .. container:: paragraph - - This is the logic for the match state. It is kept very - simple. Beside taking the trigger event, it also - creates a timestamp. This timestamp is later used for - SLA and downtime calculations as well as for some - performance information of the policy . - Sample |taskMatch_link| - - -Logic: Policy Establish State ------------------------------ - - .. container:: sect1 - - .. container:: sectionbody - - .. container:: paragraph - - This is the logic for the establish state. It is the - most complicated logic, since establishing a situation - for a decision is the most important part of any - policy. First, the policy describes what we find (the - switch block), in terms of 8 normal situations and 1 - extreme error case. - - .. container:: paragraph - - If required, it creates local context information for - the problem (if it is new) or updates it (if the - problem still exists). It also calculates customer SLA - downtime and checks for any SLA violations. Finally, - it creates a situation object. - Sample |taskEstablish_link| - -Logic: Policy Decide State --------------------------- - - .. container:: sect1 - - .. container:: sectionbody - - .. container:: paragraph - - The decide state can select between different - algorithms depending on the situation. So it needs a - Task Selection Logic (TSL). This TSL select a task in - the current policy execution (i.e. potentially a - different one per execution). - Sample |tslDecide_Link| - - .. container:: paragraph - - The actual task logic are then ``none``, ``solved``, - ``sla``, and ``priority``. - Sample task logic are as given below : - - .. container:: ulist - - - |taskDecideNone_link| - - |taskDecideSolved_Link| - - |taskDecideSla_link| - - |taskDecidePriority_Link| - - -Logic: Policy Act State ------------------------ - - .. container:: sect1 - - .. container:: sectionbody - - .. container:: paragraph - - This is the logic for the act state. It is simply - selecting an action, and creating the repsonse event - for the orchestrator (the output of the policy). - Sample |taskAct_link| - -CLI Spec --------- - - .. container:: sect1 - - .. rubric:: Complete Policy Definition - :name: complete_policy_definition - - .. container:: sectionbody - - .. container:: paragraph - - The complete policy definition is realized using the - APEX CLI Editor. The script below shows the actual - policy specification. All logic and schemas are - included (as macro file). - Sample |vpnsla-apex_link| - - -Context Events Nodes --------------------- - - .. container:: sect1 - - .. container:: sectionbody - - .. container:: paragraph - - The following events create all nodes of the topology. - - .. container:: ulist - - - |ctxtNodesJson_link| - - -Context Events Edges --------------------- - - .. container:: sect1 - - .. container:: sectionbody - - .. container:: paragraph - - The following events create all edges of the topology. - - .. container:: ulist - - - |ctxtEdgesJson_link| - - -Context Events Customers ------------------------- - - .. container:: sect1 - - .. container:: sectionbody - - .. container:: paragraph - - The following events create all customers of the topology. - - .. container:: ulist - - - |ctxtCustomerJson_link| - - -Trigger Examples ----------------- - - .. container:: sect1 - - .. container:: sectionbody - - .. container:: paragraph - - The following events are examples for trigger events - - .. container:: ulist - - - |triggerEdgeJson_link| - -Link Monitor ------------- - - .. container:: sect1 - - .. container:: sectionbody - - .. container:: paragraph - - The Link Monitor is a Python script. At startup, it - sends the context events to APEX to initialize the - topology and the customers. Then it takes events from - Kafka and sends them to APEX. - Sample |linkMonitor_link| - -Mininet Topology ----------------- - - .. container:: sect1 - - .. container:: sectionbody - - .. container:: paragraph - - The topology is realized using Mininet.
