The Precision Time Protocol (PTP), defined in IEEE 1588, is a protocol used to synchronize clocks throughout a network. The packet parser block extracts the fingerprint (an ID for the PTP packet) after decoding the PTP packet and sends the fingerprint to MAC Tx along with the packet. Target quality benchmark to provide sufficient PTP synchronisation along the base stations, is to have a PTP deviation lower than 500ns (rms). network is packet-based, relying either directly on the Ethernet network protocol or on a UDP/IP stack. Agema is a Delta product line of Open Networking Solutions for data centers, services providers and enterprises. The internal modular design allows the unit to be factory-configured per the user’s requirements. The CS2100 multiplies the PTP clock to the required MCLK frequency and reduces the jitter as shown in Figure 4-3.

Introduction to Networking and Systems Measurements A packet generator for ≥10 Gbit/s Ethernet (PTP) – microseconds. For 1-step mechanism, the 1588 logic generates a timestamp T1 for the Sync packet before sending it to the PHY. 38) with 82574L and 82566DC-2 (which are not HW timestamp compatible). IEEE std C37. The SYNC packet includes the master’s origin timestamp M i and each slave records the time S i at which it received the ith SYNC packet. It will supply accurate time for all computers and time keeping devices on the network. T Control Generate industry standard and custom physical and packet timing signals. It embeds a GPS (GNSS) receiver (this is still the most effective way to keep in sync with the outside world), the necessary protocol building blocks, PTP packet generator and responder, high accuracy timestamping unit, adequate algorithms and oscillator, and the ability to fanout the PTP packets to multiple physical ports of various operating modes (electrical and optical) supporting common networking speeds (100M,1G, 2. At the network component identified in the address, the packet is received at a first port; the command is read; the packet is forwarded via a second port to the decryption component for decryption; and a response packet is forwarded, including a response and the command identifier, to the user terminal. Developed a packet generator that generates a subset of Layer 2 (Ethernet), IPv4 and IPv6 packets that generate PTP packets and a few non-PTP related packets. org protocol dissector with Osmocom additions (obsolete) Harald Welte. statistics based on an mbox file. MoonGen is able to saturate 10 GbE links with minimum sized packets using only a single CPU core by running on top of the packet. The results are shown in Figure 3.
