The software we need to develop is a windows desktop application that has 3 main screens. The basic tasks of the application are 1) to collect/modify data from a DB, via simple SQL scripts, 2) to establish a connection on a TCP/IP socket to a local server and exchange information in that socket, 3) to get real-time video streamings (preferrably with the ONVIF protocol) from few video surveillance IP cameras and display the videos on a multi-frame screen. Attached you could find a series of screenshots of the software, with explanations of how the UI should "feel" and work. The application should be optimized for portrait-oriented TOUCH-screens. It should also be resizable to fit different resolutions (even though it will be run by modern desktop computers or tablets, so full-HD is to be expected). The UI language will be Italian. We will provide all the wordings. The application should be developed in Java and it should be opened in the NetBeans environment. Currently we already have an application written in C++, similar to what we aim to achieve now. This application has limited functionalities compared to the ones described above and is still a little buggy/unrefined, but we can provide the code for reference or help. We are looking for an experienced developer in Java, with intermediate understanding of SQL commands, ability to establish a TCP/IP connection to a server and exchange data strings on it. We are also looking for someone that can help us finding a technical solution for the video-streaming environment of the software, since this part is still not very well defined. The DB to which the application should connect to retrieve some info is Firebird/Interbase type.

I'm looking for a developer that has already written once an application that uses TCP Hole Punching, I've already written an application but I have issues with the socket port binding. The server part is already written, so both clients already have the Public and Private info of each other I just can't get the clients to connect. I'm not looking for someone to figure this out for me, I'm looking for someone that understands what TCP Hole Punching is and has already done it before using a .NET language. If you've done this before but are not happy with the price, please let me know and I'll gladly negotiate. This is an urgent project, and I expect you to be able to explain this to me quite fast or provide me with a working code sample. I will share the code with you if you're the right candidate. Thanks you

We are looking to implement the attached paper for testing purposes. the paper explains how to add FEC for steams with open source software. Forward Error Correction is an efficient solution to the packet loss problem. Data source symbols being sent across a network may be encoded using erasure codes to create redundant data. This redundant data may then be decoded on the receiving end to recover dropped packets. Many different erasure codes exist. The FEC component of this video streaming library has been implemented using Reed-Solomon based codes from an open-source erasure coding library, Jerasure. Reed-Solomon codes fall under the category of erasure codes labeled as MDS (Maximum Distance Separable). MDS codes have a nice property: k source symbols can be encoded to create m repair symbols such that among the k+m total symbols, any m erasures are tolerable. This means that data recovery is possible for any combination of m packets lost as long as at least k packets are received. The type of packet(s) received (source or repair) does not matter. Kindly check the attached paper for more information. please read the paper carefully and place your bid with REAL value.

I've written a best selling Cisco CCNA RS manual but need help updating it for the brand new CCNA topics which are listed below. I need theory notes writing with comprehensive images when required which I will have recreated by my designer. Most of the topics will also require either mini labs for students to practise the configuration commands and or main labs copying the format I currently use in my manual. I will have your notes proofread and then added to the current manual. You must be a current CCIE RS lab qualified with a CCIE number. I don't want any written only applicants. Must be able to write in clear English: Describe how cloud resources impact an enterprise architecture. This topic includes a discussion of traffic paths to internal (e.g. enterprise) and external (e.g. cloud) resources, virtual services, and basic virtual network architecture. Configure and verify LLDP (Link Layer Discovery Protocol). LLDP is an industry-standard protocol that performs similar features to CDP (Cisco Discovery Protocol). Configure, verify, and troubleshoot multi-area OSPFv2 for IPv4 networks. The previous CCNA version only required that you be able to configure and verify single area OSPFv2. However, this configuration is basic, and does not include authentication, filtering, manual summarization, route redistribution, stub areas, virtual links, or LSAs. Configure, verify, and troubleshoot VLAN Trunking Protocol (VTP) version 1 and 2. Configure, verify, and troubleshoot multi-area OSPFv3 for IPv6 networks. The previous CCNA version only required that you be able to configure and verify single area OSPFv3. However, this configuration is basic, and does not include authentication, filtering, manual summarization, route redistribution, or stub areas. Configure, verify, and troubleshoot EIGRP for IPv6 networks.The previous CCNA version only required that you be able to configure and verify EIGRP for IPv4 networks. However, this configuration is basic, and does not include authentication, filtering, manual summarization, route redistribution, or the stub feature. Configure, verify, and troubleshoot RIPv2 for IPv4. The previous CCNA version did not include any version of RIP. However, this configuration is basic, and does not include authentication, filtering, manual summarization, or route redistribution. Configure and verify Multilink PPP (MLPPP). This feature allows multiple physical interfaces to be logically bundled into a single virtual interface, which can improve WAN throughput. Describe Internet VPN options, including Dynamic Multipoint VPN (DMVPN), site-to-site VPN, and client VPN. Configure and verify a single-homed eBGP (External Border Gateway Protocol) IPv4 connection. Personally, this is the biggest surprise on the new CCNA blueprint, because BGP topics have traditionally been considered too advanced for the CCNA certification. However, the BGP configuration is a basic one, limited to peering and route advertisement using only the network command. Describe Quality of Service (QoS) concepts. This topic includes the theory of marking traffic, trusting certain devices (e.g. Cisco IP Phones), prioritizing some traffic types over others (e.g. preferring voice traffic over network gaming traffic), setting a speed limit on traffic using policing and shaping, and congestion management (i.e. using queuing technologies to allocate bandwidth amounts for different traffic classes). Describe how to secure network access using 802.1x. Explain how to use DHCP snooping to prevent a malicious user from adding their own DHCP server to a network, for the purpose of sending inaccurate IP addressing information to DHCP clients. Verify IPv6 Access Control Lists (ACLs). The previous version of the exam only tested on IPv4 ACLs. Verify Access Control Lists (ACLs) using the APIC-EM Path Trace ACL Analysis tool, where APIC-EM stand for Application Policy Infrastructure Controller – Enterprise Module. Discuss how to secure devices using AAA (i.e. Authentication, Authorization, and Accounting) with either the TACACS+ or RADIUS protocols. Using ICMP echo-based IP SLA to troubleshoot connectivity. Instead of using a basic Ping command to test for connectivity, the IP SLA features allows you to specify the characteristics of traffic sent to a destination network device. Be able to use the Local Switched Port Analyzer (SPAN) features to troubleshoot network issues. SPAN allows you to connect a network monitor to a switch port. That port can then receive a copy of traffic seen on another of the switch’s ports or VLANs, allowing the network monitor to analyze that traffic. Discuss network programmability in an enterprise network architecture. This discussions covers the function of a controller, the separation of the control plane and the data plane, and northbound vs. southbound APIs.
