    [Skype for Business] Configuration QoS dans un environnement sans-fil Cisco

    La technologie AVC (Application Visibility and Control) permet de classifier et prioriser le flux des différents clients lync dans un WLAN

    Technologie utilisant NBAR2 (Based Application Recognition) classifie le flux applicative via une base de signatures, vous pouvez identifier la version de Lync 2013 et également sous-classer les différents trafic (video, audio,...) et appliquer la stratégie adéquate.

    Le trafic sans fil Wi-Fi est identifié par un identificateur d'ensemble de services (SSID). Dans la définition d'un SSID particulier, il ya une plage de classes de priorité d'utilisateur WMM (0-7) qui correspondent à peu près au classe de priorités 802.1Q.

    AVC DSCP marque seulement les paquets originaux dans le controlêur dans les deux directions (upstream and downstream).

    Description (source cisco):

    Upstream

    1. Packet comes with or without inner DSCP from wireless side (wireless client).
    2. AP will add DSCP in the CAPWAP header that is configured on WLAN (QoS based configuration).
    3. WLC will remove CAPWAP header.
    4. AVC module on the controller will overwrite the DSCP to the configured marked value in the AVC profile and send it out.

    Downstream

    1. Packet comes from switch with or without inner DSCP wired side value.
    2. AVC module will overwrite the inner DSCP value.
    3. Controller will compare WLAN QoS configuration (as per 802.1p value that is actually 802.11e) with inner DSCP value that NBAR had overwritten. WLC will choose the lesser value and put it into CAPWAP header for DSCP.
    4. WLC will send out the packet to AP with QoS WLAN setting on the outer CAPWAP and AVC inner DSCP setting.
    5. AP strips the CAPWAP header and sends the packet on air with AVC DSCP setting; if AVC was not applied to an application then that application will adopt the QoS setting of the WLAN.

    Depuis la version 7.6, des applications AVC sont disponibles pour Lync, vous pouvez les trouver dans Wireless - Application Visibility and Control - Profil AVC:

    [Skype for Business] Sonus SBC firmware version 5

    Sonus a publié un nouveau firmware pour les versions SBC 1000/2000:

    Version: 5.0.0

    Nouvelles fonctionnalités:

    ASM Enhancements: The ASM now supports images based on Microsoft Windows Server 2012R2.

    Skype for Business: Sonus SBC 1000/2000 is now certified for Microsoft's Skype for Business.  All existing Sonus 1000/2000 features and Lync 2010/2013 features interoperate with Skype for Business. Also, all features released in Skype for Business are compatible with Sonus SBC 1000/2000.

    Third Party Skype/Lync Presence: The Third Party Skype/Lync Presence feature enables the status of non-Lync endpoints to be communicated on behalf of Lync Clients. Presence will be updated when a call is connected to indicate “On-the-Phone/Busy”. At the end of a call, Presence will be updated to clear the Busy status.

    NTTCom Support: Several enhancements are now included for NTTCom certifications.
        
    NFS Storage: The Sonus 1000/2000 provides storage for the Sonus SBC 1000/2000's internal files. This feature is applicable only if the Sonus SBC 1000/2000 has an ASM module installed.

    NAT Traversal/NTP Latching: The NAT Traversal/NTP Latching feature enables SIP endpoints that are behind NAT routers to register and communicate with the Sonus SBC 1000/2000. This feature handles NAT Traversal for both signaling (SIP) and media (RTP).

    Split DNS: The SBC1000/2000 can now be configured to use a Primary DNS Server, a Secondary DNS Server, and a Domain Specific DNS Server (Split-DNS) to resolve FQDNs.

    Direct Media: Direct Media support for SIP-to-SIP calls enables SIP Signaling to go through the SBC 1000/2000 without media being passed through the SBC. Endpoints on either side are reachable directly and negotiates the codecs and media capabilities, without any need for the SBC support for the media path (audio streams run directly between the endpoints).

    Connected Name Support: Connected Name is now supported in SIP and QSIG ISDN. The SIP Connected Name is derived from the To header.

    Packet Capture: Packet Capture is a new diagnostic feature in the Sonus SBC 1000/2000, which captures IP traffic to troubleshoot problems, such as SIP, AD, etc. Through Packet Capture configuration, select what should be included in the packet capture, such as interface, protocols, media, and hosts.

    Easy Configuration: The Sonus SBC 1000/2000 Web interface now includes a built-in step-by-step setup Easy Configuration wizard, which enables end-users to quickly deploy SBC1000/2000 within a couple of minutes. Depending on the scenario or application in which the SBC is deployed, the Easy Configuration Wizard configures the SBC, Skype for Business/Lync, IP Phones, or ISDN in a very easy manner.
        
    Auto Configuration with BroadSoft Web Services: Sonus SBC 1000/2000 now enables configuration and and updating of SBC 1k/2k remotely from a BroadSoft Server, using SIP NOTIFY message. Configuring, firmware, and software updates are supported. This feature uses password authentication and HTTPS for accessing files, and updates are performed only if required.

    SIP Registration and Subscription WebUI: A new feature has been added to the Sonus SBC 1000/2000 to monitor selected SIP register and subscribe sessions.

    Initial Setup Enhancement: The Initial Setup Enhancement features provides the ability to configure Ethernet 2 in the Initial Setup, along with Additional Routes apart from the Default Route in the Initial Setup Page.

    Alarm and Event History: The Alarm/Event History display provides diagnostics and troubleshooting capabilities for the Sonus SBC 1000/2000 by rendering the latest alarms/events in the system.

    [Skype for Business] Cisco WLC et SDN

    Avec la version de firmware 8.1.102.0, les controleurs sans-fil Cisco supporte le SDN Lync:

    Cisco WLC integration with Lync SDN API —This feature enables a Cisco WLC to integrate with a Microsoft Lync Server. Using Microsoft Lync SDN API, the Lync Server sends a notification when a Lync event, such as a voice call, video call, file transfer, or Desktop sharing, occurs on the network. The Cisco WLC interprets the API message, to take the appropriate QoS actions, and provides more visibility (mean opinion score [MOS] or Lync Client Heath) into the Lync events on the wireless network using the Lync SDN dashboard.

    Observation:

    In Cisco Wireless Release 8.1.102.0, Microsoft Lync SDN API 2.0 is supported (with backward compatibility flag set to “true”).

    The Cisco WLC integration with Lync SDN API feature is not supported on Cisco 2504 Wireless Controller.
