    MTU and MSS     MTU stands for "Maximum Transmission Unit." MTU is a networking term that defines the largest packet size that can be sent over a network connection. The MTU is typically limited by the type of connection, but may sometimes be adjusted IT network settings. The typical value of the Network MTU is 1514 Byte. If a system sends packets over an Ethernet network that are larger than this size, the data will be fragmented into smaller packets. When referring to Ethernet MTU this includes 4 Byte checksum. The  1514 Byte is the interface MTU without the Ethernet Checksum. In cae there are limitations by the type of connection, the packets will then need to be reassembled on the receiving side (e.g. Bosch video management software or Bosch hardware decoder). However, it can be beneficial to optimize the packet size on the sender side (e.g. IP camera) to the exisitng network infrastructure. As MTU maximum packet size is layer 1 related, the IP MTU that you can be adjusted at the BOSCH device configuration (Configuration Webpages or with the help fo BOSCH configuraiton software like "Configuraiton Manager"). The BOSCH GUI refers to this as “Network MTU”. BOSCH products can manage fragmented data. MSS stands for "Maximum Segment Size" The MSS value is calculated from the MTU. MSS = MTU – (layer 3 TCP header [20 Byte] + Layer 2 IP header [20 Byte]+ Layer Ethernet 1 [6+6+2 = 14 Byte]) For example looking at CPP 6 Platform – like FLEXIDOME IP panoramic 7000 MP in Firmware version 6.50.0128 you can adjust and find the following values: Network MSS (in Byte) - default value = 1460 iSCSI MSS (in Byte) – default = 1460 Network MTU (in Byte) – default = 1514   MTU and MSS can be adjusted at all released firmware versions 4.x and later.

    Which Bosch encoders and decoders are compatible with BVMS? Up until some years ago, new released cameras, encoders, domes and decoders that are introduced into market after a BVMS release could not be connected to an existing BVMS version because these cameras where not known to the BVMS. In the BVMS 4.5.1, a new concept was introduced. This concept treats Bosch video encoders and decoders as generic devices, and automatically recognizes specific device functionality (for example the number of streams, relays and inputs). Based on this information the, at that time, unknown device is added to the system and can be used by the operator. The attached document provides a detailed description of this functionality.
