IPv4/IPv6 Endpoint Option

• IPv4 or IPv6 Endpoint Option transports IP Address, Layer 4 Protocols (e.g. UDP or TCP), and Port Number.
  IPv4 Endpoint Option或IPv6 Endpoint Option 用來傳輸IP地址，第4層協(xié)議（例如UDP或TCP）和端口號。

• When receiving a Service Discovery message offering a service and transporting an IPv4 Endpoint Option or IPv6 Endpoint Option, ECUs receiving this message can dynamically configure the Socket Adaptor for using this service by updating a Socket Connection.
  當(dāng)ECU收到的Service Discovery message是offer服務(wù)并發(fā)送了IPv4 Endpoint Option或 IPv6 Endpoint Option時，則該ECU可以通過更新Socket連接來使用這個服務(wù)。

• Every OfferService entry shall reference up to two IPv4 or Endpoint Options (up to one for UDP and up to one for TCP) that describe endpoint(s) (IP and Port) the server accepts methods on and sends events from for this service instance.
  每個OfferService entry最多應(yīng)引用兩個IPv4端點選項（最多一個用于UDP，最多一個用于TCP），用于描述服務(wù)器端為這個服務(wù)實例接受Method和發(fā)送Event的端點（IP和端口） 。

• Different service instances of the same service on the same ECU shall use different endpoints, so that they can differentiated by the endpoints. Different services may share the same endpoints.
  同一ECU上相同service的不同service instance應(yīng)使用不同的endpoint，以便endpoint能區(qū)分它們。不同的service可能共享相同的endpoint。

• Every SubscribeEventgroup entry shall reference up to two IPv4 Endpoint Options (up to one for UDP and up to one for TCP) that describe(s) the endpoints (IP and Port) the client wishes to receive events. The client shall use these endpoints for sending methods as well.
  每個SubscribeEventgroup條目最多應(yīng)引用兩個IPv4端點選項（最多一個用于UDP，最多一個用于TCP），用于描述客戶端希望用于接受Event的端點。客戶端也應(yīng)該使用這些端點來發(fā)送Method。

• IPv6 Endpoint Option, which is the same as the IPv4 Endpoint Option except that it transport IPv6 Addresses instead IPv4 Addresses.
  IPv6端點選項與IPv4端點選項相同，只是它將傳輸IPv6地址而不是IPv4地址。
