Difference between direct TCP & WAP

Hello

I'm confused on the difference between 2 Protocol: direct TCP & WAP.

What really happens for each protocol? What are the differences?

(Of course the connection string for OpenConection is difference but what the architecture of the network)?

How does WAP support roaming is not the case for direct TCP?

Thank you

Hai

Ah. If I have understood correctly, you're asking about TCP and WAP as technologies, not on the programming for them.

I recommend you to read wapforum.org technical WAP white paper to learn more about WAP technology.

WAP is more than a communications architecture, involving several layers of the OSI model. It defines the protocols at the transport level application; It does not have the network, linking of data or physical layers. Analogue to the TCP WAP worldwide is WTP - Wireless Transaction Protocol. Similarly, WML - Wireless Markup Language - is the equivalent in WAP in HTML format. WAP 2.0 introduced the TCP, IP, and HTTP protocols to WAP.

Carriers have invested heavily in technology WAP and generally provide strong support throughout their networks. He can't even for TCP/IP directly (although it seems change quickly).

There is nothing inherent TCP that prevents homelessness; in fact, it has been around for years. My impression is that carriers have just does a better job of integration WAP cellular technology.

Also, I believe that it can be added cost of data to users for direct TCP using compared to WAP 2.0.

The sticky thread by Peter Strange looks at some of this. Others on this forum are better informed of what I am and I hope that they will quickly correct any inaccuracies and also provide you with a better answer.

  • Difference between IPSec over TCP and UDP IPsecover

    Hello world

    I'm testing the VPN to the user's PC.

    When I test the PC of the user using IPsecoverTCP it uses protocol 10000.

    When I check on ASA - ASDM under connection details

    ike1 - UDP Destination Port 500

    IPsecOverTCP TCP Dst Port 10000

    using Ipsecover UDP

    IKEv1 - Destination UDP 500 Port

    IPsecOverUDP - Port of Destination UDP Tunnel 10000

    Therefore when using TCP or UDP uses the same port 500 and 10000.

    Is need to know what is the major difference between these two connections just TCP or UDP?

    Concerning

    MAhesh

    IPSec over TCP is used in scenarios where:

    1 UDP port 500 is blocked, resulting in incomplete IKE negotiations

    2 ESP is not allowed to cross and encrypted traffic thus do not cross.

    3. network administrator prefers to use a connection oriented protocol.

    4. IPSec over TCP may be necessary when the intermediate NAT or PAT device is stateful firewall.

    As there are IPSec over UDP with IPSec over TCP, there is no room for negotiation. IPSec on the TCP packets are encapsulated from the beginning of the cycle of implementation of the tunnel. This feature is available only for remote access VPN not for tunnel L2L. Also does not work with proxy firewall.

    While IPSec via UDP, similar to NAT - T, is used to encapsulate ESP packets using a UDP wrapper. Useful in scenarios where the VPN clients don't support NAT - T and are behind a firewall that does not allow the ESP packets to pass through. IN IPSec over UDP, the IKE negotiations has always use port UDP 500.

  • Hi, I can not find the cuda switch in my PowerMac dual g4 in the opposite direction, what is the difference between reset pram by touch or cuda?

    Hello

    I can't find the switch cuda in my PowerMac g4 dual mirrored, 1.00

    Thanks for your attention and sorry for my English...

    First of all, I have to warn. G4 MDD don't have a CUDA button and old Macs - it has a PMU reset button. The difference is that, for a computer with the PMU system like yours, you give the key ONLY a short thrust, not longer than a second.

    If treat you it as if it was a CUDA button and hold for 20 seconds, you will seriously damage your computer. That said, this image shows the location of the PMU reset in a G4 MDD:

    What is the difference between reset pram by keyboard or cuda?

    Since your G4 has no CUDA reset ability, this becomes a moot point. In the old Mac (G3 Beige and more - the "Old world ROM" Macs) reset PRAM via the keyboard is not completely zero everything; the CUDA reset did.

    Hello

    Do you know what are the main differences between terminals AMP installation and activation of malicious software services in the management of Firesight Center?

    They are not doing the same thing or is there a big difference?

    Thanks in advance.

    Hello

    There is difference. AMP on client's protection of endpoint that is controlled by the connection of cloud and Firesight central management console can be (optionally) connected to it to collect the reports of customers as well.

    While the activation of services of malware in the CMF (firesight) resembles a network based AMP that can detect/prevent malware from traffic passing through a managed sensor.

    Final AMP is more for customers who are moving and are not always behind a firewall/sensor protected.

    This could shed more light.

  • Portege R600 - difference between the cooling options

    I have a Portege R600 with Windows 7 installed, but I guess my request is generic for all Porteges regardless of the version of Windows.

    Could someone please explain to me what really mean "options of cooling" in the power settings? I could not find the details of anywhere.

    Optimized battery means that the cpu fan is activated only beyond a certain temperature? And what is the difference between cooling and maximum performance?

    Is there another way to set the speed of the cpu fan directly?

    It is a very important point for me, because the fan of the Portege is terrible, too noisy, insofar as I plan to return the laptop unless I find a solution. Sometimes, this looks like a Ferrari to RPM 1 billion engine!

    Thank you!

    Hello

    I think the explanation is quite simple: optimized cooling battery means that the fan is activated only on a temperature higher than the maximum performance mode and that s all I think.

    For example, if I put the battery optimized cooling notebook is a little hotter than the maximum performance mode, but if I can save energy. ;)

    In addition it s advisable to clean the laptop from time to time using a jet of compressed air!

  • What is the difference between AXIEM and EMSIght? What are the benefits of AXIEM by EMSight if any?

    I wonder what are the differences between AXIEM and EMSight. Are associated with application? One is better than the other? Please explain.

    AWR estimated AXIEM most powerful plan EM Simulator around.   AXIEM is at the center of continuous research and improvement, while EMSight is only worked on if revealed serious flaws.  Here is a summary of the differences:

    Mesh

    • EMSight must mesh the nearest grid drivers using rectangles.  This causes the mesh to have more elements mesh when there are small and large geometries.  The grid should be small enough to capture the small geometry but then causes large geometries to mesh more.   In addition, angled or curved structures causes inefficiencies mesh.

    • AXIEM STS forms, rather than a grid.  In addition, the mesh can be rectangle or triangle.   This allows a much more efficient mesh.   AXIEM generally have a much more efficient

    • AXIEM contains the ability to process forms to clean geometries that cause inefficiencies of the mesh.  EMSight does not have this feature.

    • AXIEM can forms thick metal mesh, EMSight can not, and user must make approximations when thick metal will change coupling (loss is recorded properly with the thickness of the metal)

    Ports

    • The ports are for the most part similar, but parasites due on AXIEM ports are less.  In addition, the AXIEM has a side wall, thus the effects of not move of the terms of reference of the edge of the line are a lot less AXIEM in.

    • Ports can be added to most any place in geometry with AXIEM.  For EMSight, the ports are usually only added outside the geometry and have limitations to the aircraft on either side of the reference speaker.

    Problem solvers

    • EMSight does not have a low frequency Solver.  Stop low-frequency and then extrapolate to DC.  This usually works well, but you must take into account if the extrapolation is accurate.  AXIEM presents both a low and high frequency Solver so will do better in a low frequencies generally much better in DC.

    • Solver of EMSight scales O (n) ^ 2 for memory and O (n) ^ 3 for the moment.   It has a special algorithm to break the question of memory, but the question of time is the killer.  AXIEM has a direct Solver which scales in the same way and an iterative Solver which will scale O (nlogn).   In other words, AXIEM can solve a lot of bigger problems than EMSight.

    • Several AXIEM processes are multithreaded as EMSight.

    Speaker

    • EMSight is inside a perfect driver side wall.   This works well if you the circuit is in the same cavity.  If not, you must know the rules of them on to the forms of space of the flanks and how that much to extend the port could reference planes.   AXIEM is not here.   AXIEM does not currently have to simulate a perfect driver side wall.

    I don't know that I missed a few aspects of the tools.   From the point of view of the AWR that AXIEM is the tool of choice, except in a few cases have been EMSight may be required.

  • Settings of the AFN for a direct TCP (3G v.s. GPRS) connection

    Today, I read a lot of articles about the transportation options for the Blackberry network.

    I installed the Tool of Network Diagnostics on my device (BlackBerry 9300 v5.0).

    I'm Tournai on "Mobile network" and disabled the "WiFi". Therefore, my device must use the direct TCP (HTTP protocol) only.

    According to this article, for a cell TCP connection, we need to set up the APN settings, otherwise we will have 'Tunnel failed' error

    http://docs.BlackBerry.com/en/developers/deliverables/21128/Network_transport_options_1293321_11.jsp

    However, without specifying the AFN, I was still able to have labour Direct TCP (HTTP).

    I'm in New Zealand, I tested the Network Diagnostic tool with 2 dgree and vodafone sim cards. Two of them work properly. Two of them are 3 G networks

    However, a lot of people on the internet saying that if they do not specify the APN for GPRS or EDGE networks, they would get the error "failure of Tunnel.

    So, I had the impression that with 3G networks, don't need us to specify the APN.

    I don't know if that's okay?

    One of the really annoying things on the treatment on the Blackberry network is its inconsistency.  I think you've hit one of them.  I saw this in the past with Vodafone, I wasn't sure that this has happened with other networks but maybe so.

    The inconsistency is the following.

    If your connection URL looks like

    http://...; deviceside = true

    If you think that this will force the connection to use the carrier TCP aka Direct TCP.  However, on some phones of brands, including Vodafone, is not correct.  On these phones a connection as it goes actually on WAP.

    To force the direct TCP, you must follow the instructions in this post:

  • Difference between are created by default and 0.0.0.0 network in BGP

    Hello

    Please I need someone to clarify what is the difference between the command "come from default" and "network 0.0.0.0 - ip route 0.0.0.0 0.0.0.0 null0" commands. I see both serve the same purpose by a default route to a counterpart of the advertising, but at the same time, I feel a difference on them.

    THX

    Kind regards

    B....

    Dear friends,

    Lingam summarizes the options to inject the default route in BGP very well. Thank you!

    In addition, let me point out a few differences between these approaches.

    The default information is created, redistribution from a different source and the network 0.0.0.0 are all similar in the resulting effect: they will inject the default route in BGP RIBS and it will be announced to all the BGP neighbors. The difference is originally from the default route that is injected into BGP:

    • default information is created causes the default route generated artificially and injected in the BGP RIB, launch to know if it is present in the routing table.
    • Redistribution and 0.0.0.0 network will inject the default route in BGP only if the default route is currently present in the routing table, and in addition in the case of redistribution, if learned by a specific protocol source we're redistribution of.

    The nearby X.X.X.X are created by default is different in that the default route is announced only this specific BGP neighbor and not to all the existing BGP neighbors as with previous approaches. The default route will not present in the BGP RIBS of the router that is configured with the command nearby X.X.X.X are created by default and so it will not usually be announced to all the BGP neighbors. At the same time, this command is similar to the default information are created in that the default route is generated artificially and didn't need to be present in the routing table.

    Lingam, let me correct a small inaccuracy: you wrote:

    The "network 0.0.0.0" command enables the router to advertise the default route because the router thinks that 0.0.0.0 is directly connected via Null0.

    In regards to the PMO, the network command does not seek for networks connected directly (as opposed to IGP protocols) but for the networks present in the routing table. They do not need to be directly connected. Properly, the statement should say:

    The command 'network 0.0.0.0' active router advertise the default route because the router has the 0.0.0.0/0 road shows in its routing table.

    Best regards

  • Direct TCP APN question

    Hello

    I recently created a blackberry application that consumes a web service using TCP direct to help our carrier APN. I discovered the AFN in this site: http://forums.pinstack.com/f24/tcp_apn_wap_gateway_and_port_carrier_settings-360/

    However when I asked our tech support carrier, it does not seem to be aware of such a CAMERA. So I'm just confused as to who provides this APN. Is RIM who welcomes direct TCP APN as they do with BIS? And it seems to be free because I was inapplicable to such a service before using it. Hope someone can enlighten me on that.

    Thank you
    Sally

    In my view, a number of carriers don't support direct TCP.  See for example:

    http://supportforums.BlackBerry.com/Rim/Board/message?board.ID=java_dev&view=by_date_ascending&Messa...

    Some of them also carry all traffic in France through this gateway is the traffic of a browser and they apply to their optimization to the source engine to reduce the data sent over the network.  It will screw you up if you wanted really want has been sent.

    If you are WAP and TCP, I think you're going to cover the majority of cases.  This will tell you how to do WAP 2, without any intervention of the user:
